firmly with both hands and gently squeeze the trigger.
5. Turn the air regulator in the direction indicated by the
arrow on the regulator to increase the power. Turn in the
other direction to decrease the power.
IMPORTANT! If the impact wrench does not tighten the
fastener to your satisfaction, do not raise the air pressure on
the compressor over 100 PSI. Pressures above 100 PSI will
strip the workpiece and damage the tool, potentially causing
tool failure and serious injury. Use other appropriate methods
and tools to tighten the nut.
6. When the fastener is tightened, release the trigger and
remove the tool and socket.
7. Use a mechanical torque wrench to check fastener torque.
8. To loosen, set the reverse valve to the right, so that the

AIR TOOL LUBRICATION
NOTICE! Only use air tool oil to lubricate the tool. Other
lubricants are not suitable and will damage the tool or cause
a malfunction during use.
NOTICE! Never use a penetrating oil to lubricate an air tool.
Penetrating oil acts as a solvent that will dissolve the tool’s
grease packing and may damage the o-rings, causing the tool
to seize or malfunction.
1. All air tools have an internal coating of grease to prevent
corrosion during shipping and storage. Remove this
grease by adding a generous amount of air tool oil in the
air inlet and then run the tool under no load until the
exhaust is clear.
2. The maintenance-free design of this tool means that the
daily addition of air tool oil is not required. However, for
optimum performance, you should add 1 or 2 drops of air
tool to the air inlet every 3 months.
3. Avoid adding too much air tool oil as this can cause premature
power loss and eventual tool failure. A qualified technician will
need to take the tool apart and clean out the excess oil.
STORAGE
When not in use for an extended period, apply a thin coat of
lubricant to the steel parts to avoid rust. Remove the lubricant
before using the tool again.
DISPOSAL
Recycle a tool damaged beyond repair at the appropriate facility.
Contact your local municipality for a list of disposal facilities or
by-laws for electronic devices, batteries, oil or other toxic liquids.
IMPORTANT! DO NOT pollute the environment by allowing
uncontrolled discharge of waste oil.
