GENERAL TROUBLESHOOTING GUIDE
SYMPTOM
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Tool runs slowly or
will not operate.
1. Grit or gum in tool.
1. Flush the tool with air tool oil, gum
solvent, or an equal mixture of SAE
10 motor oil and kerosene. If air tool
oil is not used, lubricate the tool
after cleaning.
2. No oil in tool.
2. Lubricate the tool according to
the lubrication instructions in this
manual.
3. Low air pressure.
3a. Adjust the regulator on the tool to a
higher setting (If applicable).
3b. Adjust the compressor regulator to
90 PSI while the tool is running free.
4. Air hose leaks.
4. Tighten and seal hose fittings, if
leaks are found.
5. Pressure drops.
5a. Be sure the hose is the proper size.
Long hoses or tools using large
volumes of air may require a hose
with an I.D. of 1/2 inch or larger
depending on the total length of
the hose.
5b. Do not use a multiple number of
hoses connected together with
quick connect fittings. This causes
additional pressure drops and
reduces the tool power. Directly
connect the hoses together.
Moisture blowing out
of tool.
1. Water in tank.
1. Drain tank. Oil tool and run until no
water is evident. Oil tool again and
run 1–2 seconds.
2. Water in the air lines/hoses.
2a. Install a water separator/filter.
NOTE: Separators only work properly
when the air passing through
the separator is cool. Locate the
separator/filter as far as possible
from the compressor.
2b. Install an air dryer.
2c. Anytime water enters the tool, the
tool should be oiled immediately.
Ratchet mechanism
slips or will not loosen
nut.
1. Ratchet mechanism is dirty.
1. Clean mechanism with air tool oil.
