GENERAL SAFETY INSTRUCTIONS

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and

instructions may result in electric shock, re and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool.

1) WORK AREA SAFETY

a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b. Do not operate power tools in explosive atmospheres, such as in the presence of ammable liquids,

gases or dust. Power tools create sparks which may ignite the dust or fumes.

c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose

control.

2) ELECTRICAL SAFETY

a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter

plugs with earthed (grounded) power tools. Unmodied plugs and matching outlets will reduce risk of

electric shock.

b. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase

the risk of electric shock.

d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep

cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk

of electric shock.

e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of

a cord suitable for outdoor use reduces the risk of electric shock.

f. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)

/ ground fault circuit interrupter (GFCI) protected supply. Use of an RCD / GFCI reduces the risk of

electric shock.

3) PERSONAL SAFETY

a. Stay alert, watch what you are doing and use common sense when operating a power tool.

Do not use a power tool while you are tired or under the inuence of drugs, alcohol or medication.

A moment of inattention while operating power tools may result in serious personal injury.

b. Use personal protective equipment. Always wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions

will reduce personal injuries.

c. Prevent unintentional starting. Ensure the switch is in the o-position before connecting to

power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your

nger on the switch or energising power tools that have the switch on invites accidents.

d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may result in personal injury.

e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the

power tool in unexpected situations.

f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g. If devices are provided for the connection of dust extraction and collection facilities, ensure

these are connected and properly used. Use of dust collection can reduce dust-related hazards.

h. Do not let familiarity gained from frequent use of tools allow you to become complacent and

ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4) POWER TOOL USE AND CARE

a. Do not force the power tool. Use the correct power tool for your application. The correct power tool

will do the job better and safer at the rate for which it was designed.

b. Do not use the power tool if the switch does not turn it on and o. Any power tool that cannot be

controlled with the switch is dangerous and must be repaired.

c. Disconnect the plug from the power source and/or the battery pack from the power tool

before making any adjustments, changing accessories, or storing power tools. Such preventive

safety measures reduce the risk of starting the power tool accidentally.

d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with

the power tool or these instructions to operate the power tool. Power tools are dangerous in the

hands of untrained users.

e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts

and any other condition that may aect the power tool’s operation. If damaged, have the

power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

g. Use the power tool, accessories and tool bits etc. in accordance with these instructions,

taking into account the working conditions and the work to be performed. Use of the power

tool for operations dierent from those intended could result in a hazardous situation.

h. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles

and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5) SERVICE

Have your power tool serviced by a qualied repair person using only identical replacement parts.

This will ensure that the safety of the power tool is maintained.

GENERAL CHAIN SAW SAFETY WARNINGS

a. Keep all parts of the body away from the saw chain when the chain saw is operating. Before

you start the chain saw, make sure the saw chain is not contacting anything. A moment of

inattention while operating chain saws may cause entanglement of your clothing or body with the saw

chain.

b. Always hold the chain saw with your right hand on the rear handle and your left hand on the front

handle. Holding the chain saw with a reversed hand conguration increases the risk of personal injury

and should never be done.

c. Hold the chain saw by insulated gripping surfaces only, because the saw chain may contact

hidden wiring or its own cord. Saw chains contacting a "live" wire may make exposed metal parts of

the chain saw "live" and could give the operator an electric shock.

d. Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is

recommended. Adequate protective equipment will reduce personal injury from ying debris or

accidental contact with the saw chain.

e. Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support.

Operation of a chain saw in this manner could result in serious personal injury.

f. Always keep proper footing and operate the chain saw only when standing on xed, secure

and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain

saw.

g. Carry the chain saw by the front handle with the chain saw switched o and away from your body.

When transporting or storing the chain saw, always t the guide bar cover. Proper handling of the

chain saw will reduce the likelihood of accidental contact with the moving saw chain.

h. Follow instructions for lubricating, chain tensioning and changing the bar and chain.

Improperly tensioned or lubricated chain may either break or increase the chance for kickback.

i. Cut concrete, masonry, and similar materials only. Do not use chain saw for purposes not intended.

For example: do not use chain saw for cutting wood, metal, or plastic materials. Use of the chain

.......read these instructions

......always wear a dust mask.

.....wear eye, ear and head protection.

.....Do not expose to rain.

.....Remove plug from the mains immediately if the

cable is damaged or cut.

do not dispose of electric tools, accessories and

packaging together with household waste material

saw for operations dierent than intended could result in a hazardous situation.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

Kickback may occur when the nose or tip of the guide bar touches an object, or when the workpiece closes in

and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking

the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may

push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose

control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety

devices built into your saw. As a chain saw user, you should take several steps to keep your cutting

jobs free from accident or injury. Kickback is the result of chain saw misuse and/or incorrect operating

procedures or conditions and can be avoided by taking proper precautions as given below:

a. Maintain a rm grip, with thumbs and ngers encircling the chain saw handles, with both

hands on the saw and position your body and arm to allow you to resist kickback forces.

Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of

the chain saw.

b. Do not overreach and do not cut above shoulder height. This helps prevent unintended tip

contact and enables better control of the chain saw in unexpected situations.

c. Only use replacement guide bars and saw chains specied by the manufacturer. Incorrect

replacement guide bars and saw chains may cause chain breakage and/or kickback.

d. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing

the depth gauge height can lead to increased kickback.

hand guard in place. Replace if damaged.

2. Splash Flap: Protects from thrown debris and slurry. Never operate without the splash ap in place.

Replace if damaged.

ELECTRICAL CONNECTION

The network voltage must conform to the voltage indicated on the tool name plate.

Under no circumstances should the tool be used when the power supply cable is damaged. A damaged

cable must be replaced immediately by an authorized Customer Service Center. Do not try to repair the

damaged cable yourself. The use of damaged power cables can lead to an electric shock.

WARNING: This machine is equipped with a Portable Residual

Current Device (PRCD) also known as a Ground Fault Circuit

Interrupter (GFCI). Always use this device whenever using the

machine to reduce the risk of shock hazards. Test and reset the

PRCD device before each use. Press the“Test” button to test.

Press the“Reset” button to energize the circuit.

WARNING!: If 110V UK machines are not equipped with a PRCD portable residual current device or

GFCI ground fault circuit interrupter interrupter, the machine must always be used with an isolating

transformer for protection in case an electrical fault should occur. Use an RCD in a separate control box

with one or more socket outlets in accordance with EN 60309-2 with the earthing contact position 1 h.

Always use a residual current device with a tripping current of 30 mA or less.

INSTALLING THE GUIDE BAR AND CHAIN

1. With the 2 side cover nuts removed and the side cover removed, slacken the tension adjustor by turning

anticlockwise.

2. Slip the guide bar into position over the studs with the hole

engaged with the adjustor pin. (the bar is symmetrical and may

be installed with either side up)

3. Place the chain around the drive sprocket rst, ensuring that

the drive links engage the sprocket teeth.

4. Starting from the drive sprocket end, loop the chain around the

guide bar nose sprocket, ensuring that the drive links engage

with the guide bar groove and remain engaged with the sprockets.

5. Place the side cover in position and thread on the 2 side cover nuts, leaving them nger tight only (to

allow the tension adjustor to be adjusted). They will be tightened fully after tensioning according to the

instructions below.

TENSIONING THE CHAIN

Note: Proper chain tension with a concrete chain saw is much looser than with a wood chain saw. It must

be loose enough to run freely with only water as its lubrication.

• An over tensioned chain will give unnecessary load to the motor and will lead to premature chain stretch,

sprocket damage, and spindle bearing damage.

• An overly slack chain could y o the guide bar and could also jump teeth on the drive sprocket, leading

to premature wear of the sprocket and the chain’s drive links.

• In use, the chain must be readjusted if it hangs below the guide bar 10mm or more

1. To tension the chain, rst loosen the 2 side cover nuts and leave

them nger tight.

CAUTION: attempting to turn the adjustor without loosening

the side cover nuts could result in damage to the adjustor

mechanism.

2. While holding the guide bar upward from the nose end, turn the

tension adjustor clockwise to tighten.

3. Rotate the chain by hand, grabbing the chain by its diamond

segments, to ensure the chain rotates freely.

WARNING: Wear gloves when handling the chain and bar.

Keep ngers away from the edges of the guide bar rails.

When worn, they will have a very sharp edge.

When the associated parts have some wear, there will be some

positions where the chain is looser and other positions where it

is tighter. Find the tightest point, and make the nal adjustment

at that position.

4. Tension is correct when the chain is free to run around the

guide bar, and the chain will hang with the drive links just barely

engaging the guide bar groove at the bottom center position.

5. Once adjustment is satisfactory, the 2 side cover nuts may be

tightened. While still holding guide bar upward, tighten the 2

side cover nuts rmly.

CAUTION: Running the saw with the side cover nuts loose will cause a hazardous situation and

could lead to damage to the tension adjustor mechanism.

WATER SUPPLY

This tool must always be used with a supply of clean water at a minimum pressure of at least 1.5bar (20 psi).

The water serves as a coolant to avoid the working surface of the diamond segments from overheating and

since it is not possible to use oil, the water also serves as the only lubricant available for the chain and guide

bar. Sucient water pressure will maximize chain life.

To connect the water supply, attach the quick-release water coupling

to a water hose and regulate the water ow by adjusting the water

feed valve.

CAUTION: Never use this tool without water, the diamonds will

overheat and the O-rings in the chain will fail from the excessive

heat.

WARNING: Check all connections of the water feed system to

ensure there are no leaks. Inspect hoses and other critical parts which could deteriorate.

WARNING: The maximum water pressure should not exceed 70 psi (4 bar).

WARNING: Never allow water to enter the motor.

NOTE: Contaminants in the water supply can easily plug up the water nozzles in the water feed system.

Ensure that the supply water is clean. If you nd that there is no water ow to the chain, then clean out

the water feed system on the machine.

NOTE: Use a wet vacuum to collect cooling water if nearby objects could be damaged by water.

DIAMOND SEGMENTS

The diamond impregnated segments on a diamond chain operate on a principle of controlled erosion. The

bond matrix holding the diamonds is continually worn away by abrasion with the work piece, exposing the

harder diamonds to stand proud from the bond matrix. Without adequate water, the segments would overheat

and be destroyed. With not enough feed pressure, there would not be adequate erosion of the bond matrix

and the segments will smooth over and become dull. This is called glazing. If the chain seems to refuse to cut

anymore, it is glazed. See below: ”SHARPENING A NEW OR GLAZED CHAIN ”

Don’t feed too gently or the diamond segments will become glazed. If you push too hard, the motor will

overload. Find the sweet spot to keep the chain steadily working.

If the cut is very deep, the work material may be obstructing the ow of cooling water. Expect increased chain

wear in this situation.

NOTE: A new chain will not have its diamonds exposed yet. They will be hidden in the bond matrix. To

open up the diamonds, sharpen in the same manner as a glazed chain below.

Closed

Water Feed Valve

SHARPENING A NEW OR GLAZED CHAIN

If the chain is new, or if the chain’s diamond segments become glazed, sharpen by making a few cuts into an

appropriate alumina oxide or silicon carbide dressing stone. Simply make shallow plunge cuts into the stone

as many times as necessary to restore its cutting performance. If a dressing stone is not available, cutting into a

highly abrasive work material, such as cinder block will also work.

CHOOSING A DIAMOND CHAIN

This chain saw uses a 25 link diamond chain and a 13”guide bar. Chains with dierent types of diamond

segments are available for dierent applications.

• Choose a chain with soft bond segments for hard materials, such as reinforced concrete. Trying to use a

chain with hard bond segments to cut hard materials will lead to unsatisfactorily slow cutting and the

chain will need to be resharpened many times.

• Choose a chain with a hard bond segments for softer, more abrasive materials. Using a chain with soft

bond segments to cut soft materials will lead to unnecessarily shorter segment life. By choosing the

correct chain for the application, cutting will be more eective and economical.

STARTING AND STOPPING TOOL

To switch on:

This machine has a lock-o type switch. First press the trigger release, then squeeze the trigger switch to

switch on. For safety reasons, the switch is not possible to lock on.

To switch o:

Release the trigger switch to stop the machine. After the machine has

been switched o, the chain will still rotate for a few seconds, take care

that parts of your body do not come into contact with the chain while

it is still rotating !

WARNING: Do not set the machine down until the

chain has stopped turning.

OVERLOAD PROTECTION, OVERHEAT PROTECTION

Overload & Load Warning Indicator

When the tool is operating within its normal load range, the LED load indicator will glow green.

When full load is reached, the load indicator will ash red. If full load is exceeded and sustained for too long,

the motor will shut down and the load indicator will glow solid red. In this case, the motor must be rst shut

o and then restarted.
