6. Select Single Sequential Actuation Operation. Check for leaks. Without pulling
the trigger, press the work piece contact against the work piece. The tool
MUST NOT operate. Holding the tool away from the work piece, pull trigger
and hold for 5 seconds. The tool MUST NOT operate. Repeat steps several
times. Without pulling trigger, press nailer against work piece and pull trigger.
The tool MUST operate. Release trigger. Driver MUST move up.
7. Select Contact Actuation Operation. Holding nailer away from work piece, pull
trigger. The tool MUST NOT operate. While still pulling trigger, press the nailer
against work piece. The tool MUST operate.
8. If Steps 1 through 7 function properly, prepare the tool for use. Select opera-
tion mode and load fasteners.
9. Set the required depth of drive.
10.Repeat these steps daily. Test again if the nailer is dropped, jammed, etc.
USING THE AIR NAILER
To drive a nail, place the work piece contact of the brad nailer against the work
piece and pull the trigger. See Figure 6.
To avoid any unexpected nailings,
perform the operation as follows:
1. Avoid placing the work piece contact
against the work piece with excessive
force.
2. Pull the trigger fully and hold it in the
fired position for 1 to 2 seconds
before releasing the trigger. This will
give the brad nailer time to complete-
ly expend the previous nail and build
enough pressure for the next nail.
DO NOT hold the trigger in a half-pulled position. This
could cause an unexpected nailing to occur if the work piece contact is permit-
ted to re-contact the work piece. Failure to comply could result in damage to
work piece.

In order to prevent the surface of the work piece from being
scratched or damaged, use the no-mar nosepiece. Install
no-mar nosepiece by pressing it into place on the nose
frame. See Figure 5.
Store the no-mar nosepiece in place when not being used.
Never use a non-relieving air coupler with the brad nail-
er. Always use couplers that release any built-up charge in the brad nailer’s
firing mechanism. A non-relieving air coupler can allow the brad nailer to
discharge a fastener while the tool is disconnected from the power source.
Failure to comply with this warning can result in serious or permanent injury
or even death to the operator or to bystanders.
When the air hose is disconnected, the pressure reservoir in the air nailer will dis-
charge removing any built-up air inside the tool.
REQUIRED DAILY PREPARATION
The following steps should be performed on a daily basis to ensure the brad nailer
is operating correctly:
1. Disconnect air supply from nailer and remove fastener strip.
2. Check all screws, nuts and pins and ensure all are tight.
3. Press the pusher release button and slide back the pusher assembly
(Overriding the reload indicator). Press the work piece contact against a work
piece ensuring smooth movement.
4. With work piece contact against the work piece, pull trigger. The trigger must
operate smoothly.
5. Connect air supply and set regulator for 70 psi. DO NOT load a fastener strip.
