PREPARATION FOR USE

Proper Use Of The Tool

Your new 1/2" Drive Impact Wrench is designed for driving, tightening and loosening threaded fasteners, usually nuts and bolts, when fitted with a suitable impact socket. Always use impact-rated extension bars, universal joints and socket adapters between the square output drive of the impact wrench and the female square drive of the socket. Do not use the tool for any other purpose than that specified without consulting the manufacturer or the manufacturer’s authorized supplier. To do so may be dangerous.

Never use the impact wrench as a hammer to dislodge or straighten cross threaded fasteners. Never attempt to modify the tool for other uses.

Work Stations

Your impact wrench should only be used as a hand operated tool. It is always recommended that the tool is used when standing with solid footing. It can be used in other positions but before any such use, the operator must be in a secure position having a firm grip and footing and be aware that when loosening fasteners the tool can move quite quickly away from the fastener being undone. An allowance must always be made for this rearward movement so as to avoid the possibility of hand/arm/body entrapment.

Putting Into Service

Air Supply

CAUTION: This air tool requires lubrication BEFORE initial use, also before and after each additional use.

WARNING: Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 psi/6.2 bar when the tool is running with the trigger fully depressed.

Use recommended hose size. It is recommended that the tool is connected to the air supply as shown in figure A on page 11. Do not connect the tool to the air line system without incorporating an

easy to reach and operate air shut off valve. The air supply should be lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used as shown in figure A on page 11 as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used then the tool should be lubricated by shutting off the air supply to the tool and then depressurizing

the line by pressing the trigger on the tool. Disconnect the air line and pour into the air inlet 1 teaspoon (5cc.) of a

suitable pneumatic motor lubricating oil, preferably incorporating

a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil.

Lubricate tool daily if used frequently, or when it starts to slow or lose power.
