daily maintenance
before and after each use:
•
Check for leaking or cracked air fittings;
bubbled, cut, or worn hoses; and
replace as required.
• place a few drops of air tool oil (not
motor oil) in the air inlet fitting.
• drain the air supply compressor
tank and the water filter separator
reservoirs.
• Make sure the trigger lock is operational
and that the collet holds the tooling
tightly. Verify that the collet nut and
insert are free of cracks and wear.
periodically as required:
•
remove the quick disconnect fitting
and clean the filter screen. see
figure
1 on page 5 for location.
• Wipe the grinder housing and the
shanks of the tool bits with a lightly
oiled cloth.
• Check and adjust the automatic in-line
oiler.

lubrication
in most cases for periodic tool use, manual
lubrication is sufficient. however, if the tool
is to be used on a consistent basis, we
recommend installing an automatic oiler to
eliminate dry runs and ensure maximum
tool life. the two methods are explained
below.
Manual Lubrication: every two hours of
use, place a few drops of air tool oil in
the air inlet fitting and at all pivot points.
do not use motor oil as the additives can
corrode the tool seals. next, connect the
tool to the air line and cover the exhaust
port (see
figure 1, on page 5) with a rag.
position the end of the tool safely away
from you, and run the tool for 30 seconds
to completely circulate the oil through the
tool and into the rag.
Automatic Lubrication: Adjust the
automatic in-line oiler. place a sheet of
paper next to the exhaust port, run the tool
at three or four 30-second intervals. When
finished, the paper should show a slight oil
stain. if no oil is seen or excessive oil drips
from the paper, adjust the oiler and repeat
this process until the adjustment is correct.
