Troubleshooting
Trouble Possible cause(s) Suggested remedy(s)
Tool runs slowly or will not
operate.
1. No oil in tool. 1. Lubricate the tool according to the
lubrication instructions.
2. Grit or gum in tool. 2. Flush the tool with air tool oil, gum
solvent, or an equal mixture of motor
oil and kerosene.
3. Low air pressure. 3. a. Adjust the regulator on the tool to
the maximum setting.
b. Adjust the compressor regulator to tool
maximum 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” 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.
6. Worn rotor blade. 6. Replace rotor blade.
7. Worn ball bearing. 7. Remove and inspect bearing for rust,
dirt and grit. Replace or clean and
regrease bearing with bearing grease.
