Setting The Air Pressure; Depth Adjustment; Firing The Tool - Power Fist 8558421 Manuel D'utilisation

8558421
WARNING: Disconnect the tool from the air source whenever clearing a jam. After
disconnecting the tool from the air compressor, there should still be enough air pressure
to fire the tool. After the air hose is disconnected, always fire the tool into scrap wood
repeatedly to make sure all of the compressed air is expended.
NON-MARRING PAD
The non-marring pad attached the nose of the tool helps prevent marring and denting when
working with softer woods.
WARNING: Disconnect the tool from the air source before removing or replacing the non-
marring pad or replacing the non-marring pad. Failure to do so could result in serious
personal injury.

SETTING THE AIR PRESSURE

The amount of air pressure required depends on the size of the fasteners 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 fastener 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.

DEPTH ADJUSTMENT

The driving depth of the fasteners are adjustable.
To adjust the depth, use the drive depth adjustment
wheel(C) on the tool.
1. Disconnect the tool from the air source.
2. Turn the depth wheel left or right to
change the driving depth. Reconnect the
tool to the air source.
3. Drive a test nail after each adjustment
until the desired depth is set.
CAUTION: 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. Never exceed 120 psi.

FIRING THE TOOL

(USING THE SELECTABLE TRIGGER)
The tool is equipped with a selectable trigger set in the single sequential actuation mode(black
trigger). The selectable trigger(blue trigger) can also be set for contact actuation mode.
SINGLE SEQUENTIAL ACTUATION MODE
Single sequential actuation provides the most accurate fastener placement.
1. Disconnect the tool from the air source.
2. Remove the o-ring from the trigger pin(D).
3. Pull the trigger pin(D) out.
4. Put the black trigger on.
