2. AIR SUPPLY AND CONNEC-
TIONS (Fig.3)
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 pres-
sure higher than the conventional nailers. To use the tool, you al-
ways need the special air compressor 1 and the air hose 2
(MAX PowerLite 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:
HN25C2: 12 to 23 bar / 170 to 320 p.s.i.
HN120: 15 to 23 bar / 210 to 320 p.s.i.
Select the operating air pressure within this range for best per-
formance 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

1.

BEFORE 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 & the 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 contact
arm against the work-piece. (The tool must not operate.)
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
PIN / NAIL LOADING
1 Lock the trigger and disconnect the air hose.
2 (Fig.4) First, push the magazine cap lever 1 to open the
magazine cap.
3 ● HN120
(Fig.5) Check adjustment:
Release the magazine lock lever 1 to detach the magazine
from the magazine hook, and remove the magazine 2 from
the magazine holder 3.
4 ● HN120
(Fig.6 to 8) Determine the magazine direction in tune with
the length of pins (or nails) used, fit the magazine collar 4
into the groove in the magazine holder, set the magazine
hook 1 onto its mating part 2, and push the magazine lock
lever 5 to secure the magazine 3.
At shipment, the magazine has been set in the direction for
the pin/nail length of 22 to 32 mm. When using 38 mm or
longer pins/nails, set the magazine reversely. Be sure to set
the magazine direction in tune with the length of pins (or
nails) used. If used in the inadequate direction, the pins (or
nails) are not fed properly.
(Fig.6) For 22 to 32 mm, (Fig.7) For 38 to 65 mm
5 (Fig.9) Set the pins (or nails) and pull out the front end of the
pin (or nail) coil.
6 (Fig.10) Push the door lever 1 to open the door 2.
7 (Fig.11) Push in the pin (or nail) coil 1 along the bridge 2
until it has reached the end. Pushing it in causes a feed
pawl 3 to swing away in between the first and second pins
(or nails). Stop pushing it there.
Confirm that the first pin (or nail) has been entirely set be-
fore the feed pawl (into the nose).
8 (Fig.12) Push the door to close it.
Push the door firmly until the door lever has clicked.
9 Close the magazine cap.
0 Connect the air chuck to the air plug. You are now ready to
drive the pins (or nails).
TEST OPERATION
1 Adjust the air pressure at 12 bar (170 p.s.i.) for HN25C2 and
15 bar (210 p.s.i.) for HN120 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. (The
tool should not fire the fastener.)
4 Adjust the air pressure as lowest as possible according to
the diameters and length of the fastener and the hardness
of work-piece.
DRIVING FASTENERS
This tool is assembled with FULL SEQUENTIAL ACTUATION.
FULL SEQUENTIAL ACTUATION OPERATION
For full sequential actuation operation, depress the contact arm
against work surface and pull trigger. A fastener will be driven.
Release both trigger and Contact Arm. Begin again.

TRIGGER LOCK MECHANISM (Fig.13)
This tool has a Trigger Lock. The trigger should be locked at all
times until you intend to drive nail into the work surface. Push and
rotate the trigger lock dial 1 clockwise from LOCK to UNLOCK
position immediately before driving nails. When fastening is com-
plete, push and rotate switch counterclockwise to LOCK position.
