7. Insert the 3 blades together into the cutting head (H)
aligning the holes closest to the top of the blades with the
top hole in the cutting head (H). Insert an allen screw
through the cutting head (H), 3 blades and then through the
bottom of the cutting head. Thread a nut (F) onto the
bottom of the allen screw. Do not overtighten the allen
screw at this time.
8. Line up the back holes of the side blades (A & D) with the
center hole in the cutting head (H). Place the spacer (E)
between the blades and insert an allen screw through the
cutting head (H), side blade (A), spacer (E), side blade (D)
and then through the bottom of the cutting head. Thread a
nut (F) onto the bottom of the allen screw. Do not overtighten
the allen screw at this time.
9. Install the assembled cutting head back onto the tool motor.
10. Tighten all 3 allen screws securely with the allen wrench.
Cutting Head Lubrication
To keep the blades operating smoothly, lubricate the contact points each time you use
the tool (see Figure 6).
Air Motor Lubrication
To maintain the maximum performance of the air tool, it must be lubricated each time
it is used. Dust, dirt, rust and oil residue will build up inside the tool and reduce the perfor-
mance. An in-line oiler is recommended for proper automatic tool lubrication (see Figure 1).
If an in-line oiler is not available, the tool can be lubricated manually through the inlet port
(see Figure 7).
1. Disconnect the air tool from the air supply.
2. Turn the tool upside down and while depressing the trigger, add 4-6 drops of air tool oil or SAE10 nondetergent oil
into the air inlet. NOTE: Depressing the trigger helps circulate the oil in the air motor.
3. Reconnect the tool to the air supply, cover the exhaust port end with a towel and run
for approximately 30 seconds to remove excess oil. NOTE: If the tool remains
sluggish after it has been lubricated, the internal components may need to be
cleaned.
To Clean:
Disconnect the air tool from the air supply and pour or spray a generous amount of
WD-40® into the air inlet with the trigger depressed. Connect the tool to the air supply,
cover the exhaust port end with a towel and run for approximately 30 seconds. Follow the
air motor lubrication instructions above after cleaning is completed to re-lubricate the tool.
After oiling or cleaning, cover the exhaust port with a towel and
operate the tool for a few seconds to safely remove the excess oil. Clean the handle and surface of the tool of
any oil residue. Failure to cover the exhaust port and clean the tool, can result in serious injury.
Note: Keep the towel away from moving parts!
SYMPTOM
Tool will not run or runs
slowly
Rough cut edges or tool
jams
USER-MAINTENANCE INSTRUCTIONS (continued)
TROUBLESHOOTING GUIDE
POSSIBLE CAUSE(S)
Grit in tool; tool gummed up
No oil in tool
Low air pressure
Air hose leaks
Applying uneven pressure
Blades are dull.
CORRECTIVE ACTION
Clean the air motor inside the tool with WD-40®
(see "user maintenance" section).
Add 4-6 drops of air tool oil into the air inlet of the
tool (see "user maintenance" section).
Adjust compressor regulator to 90 PSI.
Tighten and seal hose fittings with Teflon® tape if
leaks are found.
Apply even pressure. Too much pressure can
cause a rough cut or cause the tool to jam.
Replace blades (see "user maintenance" section).
