2. AIR SUPPLY AND CONNECTIONS
(Fig.2)
A. HOSES AND SUPPLY SOURCE:
WHEN USING THE TOOL, BE SURE TO USE A SPECIAL AIR
COMPRESSOR (1) AND AIR HOSE (2).
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 and air hose (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:
18 to 23 bar (250 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. Oil added thru the air line connection will lubricate
the internal parts.
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 & 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
SCREW LOADING
1 (Fig.3) Open the Magazine:
Pull up Door Latch 1 and swing Door 2 open. Swing Mag-
azine Cap open.
2 (Fig.4) Screw loading:
Place a coil of screws in the magazine. Uncoil enough
screws to reach the feed pawl, and place the second screw
on the feed pawl. The screw heads fit in slot on the nose.
3 (Fig.5) Swing Magazine Cap closed.
4 Close the door.
5 Check that latch engages. (If it does not engage, check that
the screw heads are in the slot on the nose.)
∗ It is also possible to close the door first, followed by the
Magazine Cap. (Fig.6)
TEST OPERATION
1 Adjust the air pressure at 18 bar (250 p.s.i.) and connect the
air supply.
2 Without touching the Trigger, depress the Contact Arm
against the work-piece.
Pull the Trigger. (The tool must 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 must fire the fastener.)
4 Adjust the air pressure as much as the lowest possible
according to the diameters and length of fastener and the
hardness of work-piece.
DRIVING FASTENERS
This tool is shipped with ANTI-DOUBLE FIRE MECHANISM 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 ANTI-DOUBLE FIRE MECHANISM TO SEQUEN-
TIAL ACTUATION (Option)
To change the trigger system, please contact MAX CO., LTD. au-
thorized distributors and have them change the system.
SWITCHING SEQUENTIAL ACTUATION (Option) TO ANTI-
DOUBLE FIRE MECHANISM
To change the trigger system, please contact MAX CO., LTD. au-
thorized distributors and have them change the system.
CONTACT ACTUATION OPERATION
For contact fire operation, pull the Trigger and depress the Con-
tact Arm against the work surface.
ANTI-DOUBLE FIRE MECHANISM OPERATION and SEQUEN-
TIAL ACTUATION OPERATION
For single fire operation, depress the Contact Arm against the
work surface and pull the Trigger. A fastener will be driven. Re-
lease trigger. Begin again.
