NOTE:
This tool features a power
regulator valve. Press the air
regulating knob (D) downward and
then slowly turn it either clockwise or
counterclockwise to have either of 4
settings pointing at the triangle mark
on the housing. The settings 1, 2, 3,
4 are only for reference and do not
denote a specific power output.
"Setting 1" is the least amount of
power while "Setting 4" is most
amount of power.
NOTE:
This tool also features a
grease cap (G) on the tool body.
Remove the screw in the grease cap
with a hex key (not provided). Use a
grease gun (not included) and insert
the gun nozzle into the grease cap.
Several drops of grease are
recommended for lubrication. After
lubrication, replace the screw secure
and tight. This will protect the rotor
gears of motor assembly in good
working condition and extend tool life.
Lubricate the rotor gears once every working day. (See Figure 9)
