1. SAFETY INFORMATION

1.1 Operating Safety

Only trained personnel are permitted to start, operate, and shut down the machine.

They have received instruction on how to properly use the machine and are familiar

with required safety devices

The machine must not be accessed or operated by children and people impaired by

alcohol or drugs.

NEVER operate this machine in application for which it is not intended.

NEVER allow anyone to operate this equipment without proper training. People

operating this equipment must be familiar with the risks and hazards associated with

it.

NEVER operate the machine with the beltguard missing. Exposed drive belt and

pulleys create potentially dangerous hazards that can cause serious injuries.

DO NOT allow anyone to stank or lean on the unit during operation.

Do not run the machine indoors or in an enclosed area such as a deep trench unless

adequate ventilation, through such items as exhaust fans or hoses, is provided.

Engine exhaust contains carbon monoxide. This is a poison you cannot see or smell.

Exposure to carbon monoxide can cause loss of consciousness and CAN KILL YOU

IN MINUTES.

Do not operate the machine with unapproved accessories or attachments.

ALWAYS Keep the safety stop switch system in adjustment and good operating

condition at all times. Do not operate the trowel if it does not work properly. Out of

control Trowels can cause serious personal injury and damage to fresh concrete

surfaces. This system will automatically stop the unit if the operator loses control of it

during operation.

ALWAYS make sure the safety stop switch is disengaged (lever in the down position)

before starting the unit. Keep one hand firmly on the handle while starting and do not

let go of the handle during operation.

ALWAYS wear protective clothing appropriate to the job site when operating the

machine.

ALWAYS close fuel valve on engines equipped with one when machine is not being

operated.

ALWAYS store the machine properly when it is not being used. The machine should

be stored in a clean, dry location out of the reach of children.

Read, understand, and follow procedures in the Operator’s Manual before attempting

to operate the machine.

1.2 Operator Safety while using Internal Combustion Engines

DO NOT smoke when refueling the engine or during any other fuel handling operation.

DO NOT refuel a hot or running engine.

DO NOT refuel the engine near an open flame.

DO NOT spill fuel when refueling the engine.

Do not touch the engine or muffler while the engine is on or immediately after it has

been turned off. These areas get hot and may cause burns.

If fuel is spilled during refueling, wipe it off from the engine immediately and discard

the rag in a safe place. Do not operate the unit if fuel or oil leaks exist-repair

immediately.

NEVER operate this equipment in an explosive atmosphere.

NEVER operate any gas powered equipment in a poorly ventilated or enclosed area.

NEVER perform any work on the unit while it is running. Before working on it, stop the

engine and disconnect the spark plug wire to prevent accidental starting.

Avoid prolonged breathing of exhaust gases.

Avoid contact with hot exhaust systems and engine parts.

Allow engine to cool before performing any repairs or service.

ALWAYS transport and handle fuel only when contained in approved safety

containers.

ALWAYS keep the area around the muffler free of debris such as leaves, paper,

cartons, etc. A hot muffler could ignite the debris and start a fire.

2. OPERATION

2.1 Operating Principle

The following instructions were compiled to provide you information on how to obtain long

and trouble free use of the machine. Periodic maintenance of the machine is essential.

Read the manual carefully and thoroughly familiarize yourself with the machine and all it’s

functions. Failure to do so may injure yourself or a bystander.

2.2 Application—Standard Features

Your new Power Trowel comes standard with many features to enhance productivity,

performance and safety. Listed below are just a few of these features.

1. Safe Stop Switch—The switching mechanism of this switch should operate freely and should

always be kept in this condition. With the switch in the OFF position, the engine should not

start or run. The purpose of this switch is to stop the engine in a runaway situation, (i.e. the

operator releasing the handle during operation).

2. Adjustable Throttle—Located in a convenient location, this push-pull throttle control can be

set to provide any blade speed from 50 to 130 RPM, and located in place at the desired

operating speed.

3. Bent Arm Adjustable—Allows blades to be adjusted to compensate for bent arms caused by

dropping or mishandling the trowel. Can be easily adjusted on-site for consistent finishing.

4. Heavy Duty Ring Guard—Protects operator and unit while providing lower center of gravity

which contributes to unit stability and performance.

5. Cast Iron Spider—Extra strong for insure alignment. Also contributes to lower center or

gravity for increased trowel performance.

6. Adjustable Handle—Can be positioned to provide comfort and control for any operator’s

height.

7. Tilt Adjustment Knob – adjusts the angle of the blades for different curing stages and

conditions of the concrete. Turning the knob clockwise increases the angle of the blades to

the concrete. Turning the knob counter-clockwise flattens or decreases the angle of the

blades.

2.3 Delivery Checks

Immediately on taking delivery of your new machine and before putting it into service.

Read the operation manual completely—it could save a great deal of unnecessary

expense.Read the engine manual supplied.

Check the general condition of the machine – has it been damaged during delivery?

Check engine oil level.

Check fuel level.

Recommended lubricants are detailed in the Care and Maintenance section.
