2. AIR SUPPLY AND CONNEC-
TIONS (Fig.2)
A. TOOL AIR FITTINGS/COUPLINGS:
CN55, CN70 and CN80 use a 1/4" N.P.T. male plug. The inside
diameter should be .28" / 7mm or larger.
CN100 uses a 3/8" N.P.T. male plug. The inside diameter should
be .39" / 9.9mm or larger. The fitting must be capable of discharg-
ing tool air pressure when disconnected from the air supply. In-
stall 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
(Air filter
3
, Regulator
4
, Oiler
5
):
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-
200nails) 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.

(Fig.3)Open the magazine:
Pull down door latch
1
and swing door
2
open. Swing
magazine cap

open.
2
(Fig.4) Check adjustment:
The nail support
1
can be moved up and down to four set-
tings. To change setting pull up on the post and twist to the
correct step. The nail support should be adjusted correctly
to the position indicated in inches and millimeters inside
magazine.

(Fig.5)Nail loading:
Place a coil of nails
1
over the post in the magazine. Uncoil
enough nails to reach the feed pawl
2
, and place the sec-
ond nail between the teeth on the feed pawl. The nail heads
fit in slot on nose.
4
Swing magazine cap closed.
5
Close the door.
Check that latch engages. (If it does not engage, check that
the nail heads are in the slot on the nose).
TEST OPERATION
1
Adjust the air pressure at 70 p.s.i. / 5bar 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 fire the fastener.)
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 CONTACT ACTUATION selected. It is
the responsibility of employer, tool owner or tool operator to se-
lect the appropriate actuation system for the fastener application
and training of tool operator before changing the trigger setting.
SWITCHING CONTACT ACTUATION TO FULL SEQUENTIAL
ACTUATION (Option)
To change the trigger system, please contact MAX CO., LTD. au-
thorized distributors and have them change the system.
SWITCHING FULL SEQUENTIAL ACTUATION (Option) TO CON-
TACT ACTUATION
To change the trigger system, please contact MAX CO., LTD. au-
thorized distributors and have them change the system.
CONTACT ACTUATION OPERATION
For contact actuation operation, hold the Trigger and depress the
Contact Arm against the work surface.
FULL SEQUENTIAL ACTUATION OPERATION (Option)
For full sequential actuation operation, activate the Contact Arm
against work surface and pull the Trigger. A fastener will be driv-
en.
PROCEDURE
1
Pulling the Trigger and keeping it
pulled.
2
Depressing the Contact Arm.
CONTACT ACTUA-
TION
The tool fires a nail each time when the
Contact Arm is depressed.
FULL SEQUENTIAL
ACTUATION
The tool cannot fire a nail.
PROCEDURE
1
Depressing the Contact Arm.
2
Pulling the Trigger and keeping it
