AIR SUpply pRESSURE AND VOlUME
Air volume is as important as air pressure. The air volume
supplied to the tool may be inadequate because of
undersize fittings and hoses, or from the effects of dirt and
water in the system. Restricted air flow will prevent the tool
from receiving an adequate volume of air, even though
the pressure reading is high. The results will be a slow
operation or reduced driving power. Before evaluating tool
problems for these symptoms, trace the air supply from
the tool to the supply source for restrictive connectors,
low points containing water and anything else that would
prevent full volume flow of air to the tool.

1. Disconnect the air supply from the tool and remove
all fasteners.
2. Check all screws, nuts, bolts, and pins on the tool. If
any of these are loose, they must be tightened with the
appropriate size wrench.
3. Hold the tool with the muzzle pressed against a
workpiece.
4. Press the trigger lock and then squeeze the trigger.
The trigger lock and trigger should move smoothly,
without binding.
5. While the tool is not loaded, connect the appropriate
air supply at 4.8 bar (70 psi) to the tool.
● Without pulling the trigger, press the muzzle
against a workpiece several times. The tool must
not operate.
● Hold the tool with the muzzle against the workpiece,
and pull the trigger. The tool must operate.
● With the muzzle still engaged on the workpiece,
release the trigger. The driver must return to its up
position.
6. If the tool successfully meets all the requirements
in this checklist, it is ready for use. Load the proper
fasteners for the desired application.
WARNINg
Do not use any attachments or accessories not
recommended by the manufacturer of this tool. The use
of attachments or accessories not recommended can
result in serious personal injury.
lUbRIcAtION
An
automatic
in-line
filter-regulator-lubricator
is
recommended (Fig. 8) as it increases product life and keeps
the product in sustained operation. The in-line lubricator
should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by
placing a sheet of paper next to the exhaust ports and
actuate the tool 10 - 15 times without fasteners loaded.
The lubricator is properly set when a light stain of oil
collects on the paper. Excessive amounts of oil should be
avoided.
If it becomes necessary to store the product for an extended
period of time (overnight, weekend, etc.), it should receive
a generous amount of lubrication at that time. Actuate the
tool 10 - 15 times without fasteners loaded to ensure oil
has been evenly distributed throughout the product. The
product should be stored in a clean and dry environment.
● 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 8.
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.
