The tool is shipped from the factory with a dual trigger
actuation system. The secondary trigger must be pulled in
order to pull the primary trigger. Each time the primary trigger
is pulled, the tool will drive a fastener.
Each time a fastener is driven, the exhaust will direct a blast
of air from the rear of the tool. Keep your face away from
this area.
 Remove fasteners or make sure that the magazine is
empty of fasteners.
 Connect the tool to an air supply.
 Load the tool with fasteners.
 Grip the tool firmly to maintain control.
 Press the nose of the tool against the work surface. Pull
the secondary trigger.
 Pull the primary trigger to drive a fastener.
 Allow the tool to recoil away from the work surface as the
fastener is driven.
WARNING:
During normal use the tool will recoil immediately
after driving a fastener. This is a normal function of
the tool. Do not attempt to prevent the recoil by holding
the nailer against the work. Restriction to the recoil can
result in a second fastener being driven from the nailer.
Grip the handle firmly, let the tool do the work, and do
not place second hand on top of tool or near exhaust at
any time. Failure to heed this warning can result in seri-
ous personal injury.
SETTING THE AIR PRESSURE
The amount of air pressure required will depend on the size
of the fastener and the workpiece material.
Begin testing the depth of drive by driving a test fastener into
the same type of workpiece material used for the actual job.
Drive a test fastener with the air pressure set at 80-85 psi.
Raise or lower the air pressure to find the lowest setting that
will perform the job with consistent results.
It may be possible to achieve the desired depth with air
pressure adjustments alone. If finer adjustments are needed,
use the drive depth adjustment on the tool.
OPERATION
DRIVE DEPTH ADJUSTMENT
See Figure 9, page 13.
The pinner is factory-set to its maximum depth.The driving
depth of the fastener may be adjusted to a more shallow
depth. It is advisable to test the depth on a scrap workpiece
to determine the required depth for the application.
To determine depth of drive, first adjust the air pressure and
drive a test fastener.
To fine-adjust to a shallower depth of drive:
 Disconnect the tool from the air supply.
 Using a 3 mm hex key, loosen the two bolts on the front
plate. Do not remove the bolts.
 Slide the front plate toward the nose slightly. Adjustment
is accomplished with very little movement of the front
plate.
 The plate should be positioned so that it cannot slip over
the bolts.
 Tighten the bolts securely with the hex key.
 Reconnect the tool to the air supply.
 Drive a test fastener after each adjustment until the desired
depth is set.
WARNING:
Disconnect the tool from the air supply before removing
fasteners or clearing a jammed fastener. Failure to do so
could result in serious personal injury.
CLEARING A JAMMED FASTENER
See Figure 10, page 13.
If a fastener becomes jammed in the tool, disconnect the
air hose and keep the tool pointed away from you while
clearing the jam.
 Disconnect the tool from the air supply.
 Remove fasteners from the magazine.
 Using a 3 mm hex wrench, remove the two bolts and front
plate.
 Remove the jammed fastener. Make sure the nail track
is free of bent fasteners or fragments.
 If the driver blade prevents removal of bent fasteners or
fragments, use a small flat-blade screwdriver to gently tap
the driver blade backwards past the jammed fastener.
 Remove the jammed fastener and make sure the nail
track is free of bent fasteners or fragments.
 Reinstall the front plate and bolts, making sure they are
secure.
 Reconnect the tool to the air supply.
 Reload the tool with fasteners.
