Lubrication
An in-line filter-regulator-lubricator
(fig 1)
is recommended
as it increases tool life
and keeps the tool in sustained operation.
The in-line lubricator should be regularly
checked and filled with air tool oil. Proper
adjustment
of the in-line lubricator is
performed
by placing a sheet of paper
next to the tools exhaust
ports and holding
the throttle open approximately
30
seconds. The lubricator is properly set
when a light stain of oil collects on the
paper.
Excessive amounts of oil should be
avoided.
In the event that it becomes
necessary
to store the tool for an
extended period of time (overnight,
weekend, etc.), it should receive a
generous
amount of lubrication through
the air inlet (Figure
3). The tool should be
run for approximately
30 seconds to
ensure oil has been evenly distributed
throughout
the tool. The tool should be
stored in a clean and dry environment.
Recommended
Lubricants
Use air tool oil or any other high grade
turbine oil containing
moisture absorbent,
rust inhibitors, metal wetting agents and
an EP (extreme
pressure) additive. See
Figure 3 for location/air
inlet.
IMPACT MECHANISM
LUBRICATION
The impact mechanism
transfers power
from the tool to a nut or bolt. Oil in the
mechanism
is forced out and must be
replaced. Lubricate the impact
mechanism
one time a year; more
often if a tool is used more than ten
hours a week.
To lubricate and clean the impact
mechanism
and the front bearing:
1. Disconnect
the impact wrench from
the air supply.
2. Remove
the slotted screw or Allen
head screw from the oil port hole (Ref. #41)
(Refer to figure
3).
3. Squeeze
approximately
1 oz. of 30 weight oil
through the oil port hole. Replace the screw.
4. Reconnect
the air supply to the impact
wrench
and run for 20 to 30 seconds.
Lubricate
the entire impact mechanism
by rotating the tool upside down
and sideways
while running the tool.
5. Remove
the screw and hold the oil
port hole over a suitable
container
to
allow excess
oil to drain. Sometimes
triggering
the tool when dumping
the oils
helps to force out the excess oil.
6. If the oil is dirty, repeat the procedureabove
until the oil comes out clear. Install the screw
and tighten.
The residual oil remaining
in the
impact mechanism
chamber
is all that is
needed for proper
lubrication.
