Operating Instructions - Cocraft HI 750-T Original Instructions Manual

Lubrication of the hammer mechanism
If you do not use the impact wrench very often, the hammer mechanism does not
need lubricating more than 1–2 times a month. If the impact wrench is used daily,
the hammer mechanism should be lubricated every day.
Disconnect the impact wrench from the air hose.
Remove the screw (2) and drip 2–3 drops of oil
into the hole. There is a little o-ring on the screw,
make sure that it is not misplaced. Screw in
the screw again, making sure that the o-ring is in
place. Engine oil can be used here.
