5.3. Put three teaspoons of air tool oil in the oil port hole. Replace the screw.
5.4. Reconnect the air supply to the ratchet wrench and run for 20 to 30 seconds.
Lubricate the entire ratchet mechanism by rotating the tool upside down and sideways while
running the tool.
5.5. Remove the screw and hold the oil port hole over a suitable container to allow excess oil to
drain.
5.6. If the oil is dirty, repeat the procedure above until the oil comes out clear. Install the screw and
tighten. The residual oil remaining in the ratchet mechanism chamber is all that is needed for
proper lubrication.
General Troubleshooting Guide
Symptom
Possible Cause(s)
Corrective Action
Tool runs slowly
or does not
operate.
1. Grit or gum in tool.
2. No oil in tool.
3. Low air pressure.
4. Air hose leaks.
5. Pressure drops.
6. Worn ball bearing in motor.
1. Flush the tool with air tool oil, gum solvent,
or an equal mixture of SAE # 10 motor oil and kero-
sene. 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.
