2. AIR SUPPLY AND CONNEC-
TIONS (Fig.4)
A. TOOL AIR FITTINGS/COUPLIGS:
This tool uses a 1/4" N.P.T. male plug. The inside diameter
should be .28" (7mm) or larger. Install a male plug on the tool
which is free flowing and which will release air pressure from the
tool when disconnected from the supply source.
B. OPERATING PRESSURE:
70 to 100 p.s.i. (5 to 7 bar). Select the operating air pressure with-
in this range for best performance based upon the fastener appli-
cation and work surface. Using the lowest acceptable to minimize
noise, vibration and wear.
DO NOT EXCEED 120 p.s.i. (8 bar).
C. HOSES 1:
Hose has a min. diameter of 1/4" (6 mm) and max. length of no
more than 17' (5 m).
The supply hose should contain a fitting that will provide "quick
disconnecting" from the male plug on the tool.
D.SUPPLY SOURCE:
Use only clean regulated compressed air with pressure regulated
not to exceed maximum air pressure marked on the tool.
If regulator fails, maximum air pressure delivered to tool shall
not exceed 200 p.s.i. (13.8 bar) or 1.5 times maximum air pres-
sure, whichever is greater.
E. 3-PIECE AIRSET 2
To optimize performance use a 3-piece air set 2. A filter 3 will
help to get the best performance and minimum wear from the tool
because dirt and water in the air supply are major causes of wear
in the tool.
Frequent, but not excessive, lubrication (one drop in every 100-
200 nails) is required for the best performance. Oil added thru the
air line connection will lubricate the internal parts.

3. INSTRUCTIONS FOR OPERATION

1.

BEFORE OPERATION

Check the following prior operation.
1 Wear Safety Glasses or Goggles.
2 Do not connect the air supply.
3 Inspect screw tightness.
4 Check operation of the contact arm & trigger if moving
smoothly.
5
Connect the air supply.
6 Check the air leakage. (The Tool must not have the air
leakage.)
7 Hold the Tool with finger-off the trigger, then push the con-
tact arm against the work-piece. (The tool must not oper-
ate.)
8 Hold the Tool with contact arm free from work-piece and pull
the trigger. (The Tool must not operate.)
9 Disconnect the air supply.
2. OPERATION
NAIL LOADING
NF255FA/18
1 (Fig.5) Push the click lever 1 and pull the slider unit 2 gen-
tly as far as it will go.
2 (Fig.6) Insert the nails 1 into the magazine 2.
3 Push the slider unit forward until it stops. Ensure the point
of nail stick to be ridden in the bottom of magazine (Fig.7).
NF565A/16
1 (Fig.8) Pull pusher 1 back into "locked" position
2 (Fig.9) Insert the finish nails 1 into the magazine.
3 (Fig.10) Push the pusher lock button 1 and put back the
pusher.
(Air filter 3, Regulator 4, Oiler 5):
NF665A/15
1 (Fig.11) Insert the finish nails 1 into the magazine.
2 (Fig.12) Pull back the pusher 1.
3 (Fig.13) Release and return the pusher.
TEST OPERATION
1 Adjust the air pressure at 70 p.s.i. (5 bar) and connect the
air supply.
2 Without touching the Trigger, depress the Contact Arm
against the work-piece.
Pull the Trigger. (The tool should fire the fastener.)
3 With the tool off the work-piece, pull the Trigger.
Then depress the Contact Arm against the work-piece.
(Tool set to FULL SEQUENTIAL ACTUATION should not
fire the fastener, but tool set to CONTACT ACTUATION
should.)
4 Adjust the air pressure as much as the lowest possible ac-
cording to the diameters and length of fastener and the
hardness of work-piece.
DRIVING FASTENERS
This tool is shipped with FULL SEQUENTIAL ACTUATION se-
lected. It is the responsibility of employer, tool owner or tool op-
erator to select the appropriate actuation system for the fastener
application and training of tool operator before changing the trig-
ger setting.
SWITCHING FULL SEQUENTIAL ACTUATION TO CONTACT
ACTUATION
1 (Fig.14) Press the button 1 on the trigger.
2 (Fig.15) Turn the switching lever 2 in the direction of the ar-
row.
3 (Fig.16) Set the switching lever as the picture.
CONTACT ACTUATION OPERATION
For contact fire operation, hold the Trigger and depress the Con-
tact Arm against the work surface.
FULL SEQUENTIAL ACTUATION OPERATION
For single fire operation, activate the Contact Arm against work
surface and pull trigger. A fastener will be driven.
