SETTING THE AIR PRESSURE
The amount of air pressure required will depend on the size
of the nail and the workpiece material.
Begin testing the depth of drive by driving a test nail into the
same type of workpiece material used for the actual job.
Drive a test nail with the air pressure set at 90-95 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.
DRIVE DEPTH ADJUSTMENT
See Figure 9.
The driving depth of the nail may be adjusted. 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 nail. To achieve the desired depth, use the drive
depth adjustment on the tool.
 Disconnect the tool from the air supply.
 Turn the depth selector left or right to change the driving
depth.
 Reconnect the tool to the air supply.
 Drive a test nail after each adjustment until the desired
depth is set.
WARNING:
Disconnect the tool from the air supply before removing
nails. Failure to do so could result in serious personal
injury.
REMOVING NAILS FROM THE TOOL
See Figure 10.
 Disconnect the tool from the air supply.
 Slide the pusher all the way to the rear of the magazine
until it locks into place.
NOTE: Always keep fingers clear of nail track of magazine
to prevent injury from unintended release of the pusher.
 Tilt the tool as shown so that the nails slide out of the
magazine.
