● It is most important that the product be properly
lubricated by keeping the air line lubricator filled
and correctly adjusted. Without proper lubrication
the product will not work properly and parts will
wear prematurely.
● Use correct lubricant in the air line lubricator. The
lubricator should be of low air flow or changing air
flow type, and should be kept filled to the correct
level. Use only recommended lubricants, specially
made for pneumatic applications. Substitutes
may harm the rubber compounds in the product's
O-rings and other rubber parts.
IMpORtANt!
See Figure 7.
If a filter/regulator/lubricator is not installed on the air
system, air operated tools should be lubricated at least
once a day or after 2 hours of work with 2 - 6 drops
of oil, depending on the work environment, directly
through the male fitting in the tool housing.
LOADINg AND OpERAtION
WARNINg
Ensure the air supply is clean and does not exceed
6.3 bar (90 psi) while operating the product. Too high an
air pressure and unclean air will shorten the product's
life due to excessive wear, and may be dangerous
causing damage and/or personal injury.
■ Clean the air inlet filter weekly.
■ Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The minimum
hose diameter should be 6.35 mm (1/4”) I.D. and the
fittings must have the same inside dimensions.
■ Keep hose away from heat, oil and sharp edges. Check
hose for wear, and make sure that all connections are
secure.
■ Use the product only for its intended purpose.
MAINtENANcE
■ Keep the product safe by regular maintenance.
■ Always keep your air tool clean and lubricated. Daily
lubrication is essential to avoid internal corrosion and
possible failure.
■ Maintenance shall be performed weekly.
■ Drain the air tank daily. Water in the air line will
damage the product.
■ If the product cannot be used anymore, make sure to
dispose of it so as not to impose hazards on people
and the environment.
■ Air tool white oil is recommended for lubrication.
■ Only lubricants recommended by the manufacturer
should be used.
■ Clean the air inlet filter weekly.

WARNINg
If any of the following symptoms appears during
operation, stop using the product immediately, or
serious personal injury could result. Only qualified
persons or an authorised service centre can perform
repairs or replacement of the product.
Disconnect the product from the air supply before
attempting repair or adjustment. When replacing O-rings
or cylinder, lubricate with air tool oil before assembly.
pROBLEM: product runs at normal speed but fails
under load.
pOSSIBLE cAUSES
■ Motor parts are worn.
■ Cam clutch is worn or sticking due to lack of lubricant.
REMEDIES
■ Lubricate 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 tool requires
14.20 ml (1/2 ounce) of oil.
grease lubrication
NOtE:
Heat usually indicates insufficient grease in
chamber. Severe operating conditions may require
more frequent lubrication.
pROBLEM: product runs slowly. Air flows slightly
from exhaust.
pOSSIBLE cAUSES
■ Motor parts are jammed with dirt particles.
■ Power regulator is in closed position.
■ Air flow is blocked by dirt.
REMEDIES
■ Check air inlet filter for blockage.
■ Pour air tool lubricating oil into air inlet as per
instructions.
■ Operate the product in short bursts quickly reversing
rotation back and forth where applicable.
■ Repeat above as needed.
