2. AIR SUPPLY AND CONNEC-
TIONS (Fig.2)
A. HOSES AND SUPPLY SOURCE
WHEN USING THE TOOL, BE SURE TO USE A SPECIAL AIR
COMPRESSOR AND AIR HOSE.
In order to improve its performance, it has set its working pressure
higher than the conventional nailers. To use the tool, you always
need the special air compressor
1
and the air hose
2
(MAX Pow-
erLite Compressor and MAX PowerLite Hose).
Use of high pressure gas (for example, oxygen, acetylene, etc.)
causes abnormal combustion, possibly resulting in explosion.
Use only the special air compressor and air hose.
B. OPERATING PRESSURE:
12 to 23 bar / 170 to 320 p.s.i. Select the operating air pressure
within this range for best performance based upon the fastener
application and work surface. Using the lowest acceptable to
minimize noise, vibration and wear.
DO NOT EXCEED 23 bar / 320 p.s.i.
NOTICE:
Frequent, but not excessive, lubrication is required for the best
performance. Upon completion of operations, place 2 or 3 drops
of oil into the air plug inlet with the jet oiler.
3. INSTRUCTIONS FOR OPERATION

OPERATION
ATTACHING THE CONTACT NOSE (HN65)
Attach the following contact noses depending on the nail head di-
ameter used.
1
(Fig.3) Pull the contact nose to remove it.
2
(Fig.4,5) Aligning the rail with the contact arm, press the
contact nose as shown in the figure to fit it until it clicks.
NAIL LOADING
1
(Fig.6) Open the Magazine:
Pull up Door Latch
1
and swing Door open. Swing Maga-
zine Cap open.
2
(Fig.7) (HN65) Check adjustment:
The Nail Support
2
can be moved up and down to four set-
tings. To change setting pull up on the Nail Post and twist to
the correct step. The Nail Support should be adjusted cor-
rectly to the position indicated in inches and millimeters in-
side Magazine
3
.
(Fig.8) (HN90F)
The nail support
2
can be moved up and down to four set-
tings. The nail support moves down by turning it counter-
clockwise and moves up by turning it clockwise. The nail
support should be adjusted correctly to the position indicat-
ed in inches and millimeters.
(Fig.9,10) (HN65J) When using 40mm / 1-1/2" nails, attach
the nail support
2
in such a manner that a mark “40” can
been seen. When using 65mm / 2-1/2" ones, attach the nail
support
2
upside down.
To detach, push the latch on the back of the magazine with
a finger.

(Fig.11) Nail loading:
Place a coil of nails
4
over the Nail Post in the Magazine.
Uncoil enough nails to reach the Feed Pawl

closed.
5
(Fig. 12) Close the Door
8
.
Check that Door Latch
1
engages. (If it does not engage, check
that the nail heads are in the slot
6
on the Nose).
TEST OPERATION
1
Adjust the air pressure at 170 p.s.i. (12 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 with red triggers should fire the fastener, but tool with
orange triggers should not.)
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.
