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
iJ, 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.
