Owner’s Manual Model No. 875.199810
Maintenance
Excessive amounts of off should be
avoided. In the event that it becomes
necessaty to store the tool for an
extended period of time {overnight,
v№ekend, 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 looi oil or any other high grade
turbine oil containing moisture absorbent,
rust inhOtitors, metal wetling agents and
an EP (extreme pressure) additive. See
Figure 3 for localion/air inief.
IMPACT MECHANISM LUBRICATION
The in^iact mechanism transfers power
from the tool to a nul or bolt. Oil in the
merltanism is forced out and must be
replaced. Lubricate the impact
mechanism one time a yean 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.
Lubrication
An in-line filter-regulator-lubricator (fig 1)
is recommended as it increases tool Bfe
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 pladng 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 coSecfs on the
paper.
2. Remove the slotted screw or Allen
head screw from the oil port hole
(Ref. No. 51) (Referto figure 3).
3. Squeeze approximately 1 oz. of 30 weight oil
through the oil port hole. Replace the screw.
4. Reconnect the ar 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 toot.
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 dear. Install the screw
and tighten. The residual oil remaining in the
impact mechanism chamber is all that is
needed for proper lubrication.
