CLEANING
Clean external surfaces of the tool with a clean, dry cloth, and apply a
thin coat of tool oil to exposed metal to prevent corrosion before storing
the tool. Remove the oil coating before using the tool again.
AIR TOOL LUBRICATION
WARNING! 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, or may be highly flammable, causing an explosion.
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. Manually add a drop or two of air tool oil into the tool’s coupler
plug before each use and after every hour of continuous use. The
tool will not work properly without lubrication and parts will wear
prematurely.
2.1 Every week, add a high-quality machine oil to the oil inlet by
removing the oil screw (B).
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.
