General Troubleshooting Guide
1. Flush the tool with air tool oil, gum solvent, or an
equal mixture of SAE # 10 motor oil and kerosene.
Lubricate the tool after cleaning.
2. Lubricate the tool according to the lubrication
instructions in this manual.
3. Adjust the compressor regulator to tool maximum
while the tool is running free.
4. Tighten and seal hose fittings if leaks are found.
5-1. 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 12.7 mm (1/2") or larger
depending on the total length of the hose.
5-2. 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. Remove and inspect bearing for rust, dirt and grit
or worn race. Clean and regress bearing with bearing
grease.
1. Drain tank. (See air compressor manual). Oil tool
and run until no water is evident. Oil tool again and
run 1-2 seconds.
2-1. 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.
2-2. Install an air dryer.
1. Lubricate the air motor and the impact
mechanism.(See lubrication section of
this manual)
2. Adjust the regulator setting of the tool.
3. Adjust regulators in the air system.
