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 Campbell Hausfeld air
tool oil, gum solvent, or an equal mixture of
SAE 10 motor oil and kerosene. If Campbell
Hausfeld 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 3. a. Adjust the regulator on the tool to the
maximum setting
b. Adjust the compressor regulator to the
tool’s maximum working pressure while
the tool is running free
4. Air hose leaks 4. Tighten and seal hose fittings if leaks are
found
5. Pressure drops 5. a. 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
b. 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

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
b. Install an air dryer

all the water from the air, install a
Campbell Hausfeld belt air filter (MP2121)
