TROUBLESHOOTING
Problem
Tool runs slowly. Air flows
slightly from exhaust:
Tools will not run. Air flows
freely from exhaust:
Tool will not shut off:
Solution
• Check air inlet filter for
blockage.
• Flush and [our air tool
lubricating oil into air inlet as
per instructions.
• Operate tool in short bursts
quickly reversing rotation
back and forth where
applicable.
• Drain air tank and supply
line
• Use PTFE tape at all fittings
and joints. Check tool for
worn or damaged O-rings &
seals.
• Pour air tool lubricating tool
into air inlet.
• Operate tool in short bursts
of forward and/or reverse
rotation where applicable.
• Tap motor housing gently
with plastic mallet.
• Disconnect supply. Free
motor by rotating drive
shank manually where
applicable
• Replace as necessary.
• Replace "O" ring.
Probable Cause
• Motor parts jammed with
dirt particles
• Power regulator in closed
position
• Air flow blocked by dirt
• Air leakage
• One or more motor vanes
stuck due to material build
up.
• Worn/damaged wear & tear
parts.
• "O" rings throttle valve
dislodged from seat inlet
Oil tool before each use.
4 to 5 drops of a good grade Air Tool Oil placed in the air inlet is
sufficient. Use proper air pressure and CFM rating listed for this tool.
Drain water from hoses and compressor tank.
Water in the air supply line will cause
gumming and loss of power. Clean the air filter on the supply line and flush the tool with
gum solvent or a 50/50 mix of air tool oil and kerosene. It may be necessary to
disassemble the tool to properly clean and re-lubricate.

TROUBLESHOOTING
The following form lists the common operating system with problem and solutions. Please
read the form carefully and follow it. Always be sure you are using a tool suited for the
torque requirements of the job at hand.
WARNING:
If any of the following symptoms appears during your operating, stop using
the tool immediately, or serious personal injury could result. Only a qualified persons or an
authorized service center can perform repairs or replacement of tool.
Disconnect tool from air supply before attempting repair or adjustment. When replacing
O-rings or Cylinder, lubricate with air tool oil before assembly.
Problem
Tool runs at normal speed
but loses power under load:
Solution
• Lubricating clutch housing.
• Check for excess clutch oil.
Clutch cases need only be
half full. Overfilling can
cause drag on high speed
clutch parts, i.e. a typical
oiled/lubricated wrench
requires 1⁄2 ounce of oil.
• NOTE: Heat usually indicates insufficient
grease in chamber. Severe operating
conditions may require more frequent
lubrication.
• Increase line pressure,
Make sure compressor
matches tool's air pressure
and consumption needs.
Probable Cause
• Motor parts worn
• Cam/clutch worn or sticking
due to lack of lubricant
• Insufficient air supply
Note:
Repairs should be carried out by a qualified person.
