SAFETY GUIDELINES

DANGER!

Potential hazard that will result in serious injury or loss of life.

•Keep children away from the work area. Do not allow children to handle

power tools.

•Do not use this tool in the presence of flammable liquids or gases. Sparks

that are created during use may ignite gases.

•Do not point the tool toward yourself or other people. Keep hands, feet and

all other parts of the body clear from work area.

•Always ensure that the workpiece is firmly secured, leaving both hands free

to control the tool.

•Always ensure that the tool has stopped after use, for safety purposes and

to prevent possible damage to the tool/user.

•Do not use oxygen or any other combustible or bottled

gas to power air-powered tools. Failure to observe this

warning can cause explosion and serious personal injury

or death. Use only compressed air to power air-powered

tools. Use a minimum of 25’(7.6 m) of hose to connect

the tool to the compressor. Failure to comply will result in

serious injury or loss of life.

•Risk of bursting: Make sure the regulator is adjusted so

that the compressor outlet pressure is set lower than the

maximum operating pressure of the tool. Before starting

the compressor, pull the ring on the safety valve to make

sure the valve moves freely. Drain water from tank after

each use. Do not weld or repair tank. Relieve all pressure

in the hose before removing or attaching accessories.

•Risk of electric shock: Do not expose a compressor to rain. Store it indoors.

Disconnect the compressor from the power source before servicing.

Compressor must be grounded. Do not use grounding adaptors.

SAFETY GUIDELINES

•Risk of personal injury: Do not direct compressed air from the air hose

toward the user or other people.

•Breathing risk: Never directly inhale the air produced by the compressor.

•Risk of bursting: Do not adjust the pressure switch or safety valve for any

reason. They have been preset at the factory for the compressor’s maximum

pressure. Tampering with the pressure switch or the safety valve may cause

personal injury or property damage.

•Risk of burns: The pump and the manifold generate high temperatures. In

order to avoid burns or other injuries, do not touch the pump, the manifold or

the transfer tube while the compressor is running. Allow the parts to cool

down before handling or servicing. Keep children away from the compressor

at all times.

WARNING!

Potential hazard that could result in serious injury or loss of life.

•Do not allow unskilled or untrained individuals to operate the Air-powered

Hammer/Chisel.

•Always ensure that the accessories are specially designed/rated for use with

the tool. Also ensure they are secured and correctly fastened before

connecting the tool to the air supply.

•Use only lightweight coil type hoses to connect the tool to the compressor

coupling.

•Locate the compressor in a well-ventilated area for cooling, at a minimum of

12"(31 cm) away from the nearest wall.

•Protect the air hose and the power cord from damage and puncture. Inspect

them for weak or worn parts every week, and replace them if necessary.

•Always wear hearing protection when using the air compressor. Failure to do

so may result in hearing loss.

•Do not carry the compressor while it is running.

•Do not operate the compressor if it is not in a stable position.

•Do not operate the compressor on a rooftop ori n an elevated position that

could allow the unit to fall or be tipped over.

CAUTION!

Potential hazard that may result in moderate injury or damage to

equipment.

•Always ensure that the tool has stopped before connecting it to the air

supply.

•Do not wear watches, rings, bracelets or loose clothing when using any air-

powered tool.

•Maintain proper footing at all times in order to ensure correct balance.

•Do not overload the tool. Allow the tool to operate at its optimum speed for

maximum efficiency.

•Do not use the tool if it is leaking air, has missing or damaged parts, or if it

requires repairs. Verify that all screws are securely tightened.

• For optimal safety and tool performance, inspect the tool daily in order to

ensure free movement of the trigger, safety mechanisms and springs.

•Always keep your air tool clean and lubricated. Daily lubrication is essential

to avoid internal corrosion and possible failures.

•Keep the work area clean. A cluttered or dirty workbench may lead to an

accident. Floors should be kept clear.

•Use the tool only in a well-ventilated area.

•Handling and storage of oil: Use with adequate ventilation. Avoid contact of

oil with eyes, skin, and clothing. Avoid breathing spray or mist. Store in a

tightly closed container in a cool, dry, well-ventilated area free from

incompatible substances.

•Do not use the tool when temperature of the work area is near or below

freezing, as doing so may cause tool failure.

•Do not store the tool in freezing temperatures to prevent ice formation on

the operating valves of the tool, as doing so may cause tool failure.

Raynaud's Disease to operate the vibrating tool.

•Seek medical attention immediately for vibration-related symptoms such as

tingling, numbness, and white or blue fingers.

•Do not smoke while using the vibrating tool to avoid the risk of the

vibration-related injury.
