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 the
maximum setting (If applicable).
3b. Adjust the compressor regulator to tool
maximum 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.
6. Worn rotor blade in motor.
6. Replace rotor blade.
7. Worn ball bearing in motor.
7. Remove and inspect bearing for rust, dirt
and grit or worn race. Replace or clean and
regrease bearing with bearing grease.
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 (PA2121).
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.
Troubleshooting Chart
