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 (Ref. 47)from the oil port hole
(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 procedure above
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.
