Set the change lever to the LOCK position to lock the
trigger.

Before driving pins, set the change lever to the FREE
position. When NOT driving pins, be sure to set the
change lever to the LOCK position and disconnect the
air hose
ASSEMBLY
CAUTION:
Always disconnect the air hose before loading the
•
nailer.
Loading the nailer
Fig.9
Disconnect the air hose from the tool. Select pins
suitable for your work. Depress the latch lever and open
the door and magazine cap.
Fig.10
Place the pin coil in the magazine. Uncoil enough pins
to reach the pin guide. Place the first pin in the feeder
and the second pin in the feed claw. Place other
uncoiled pins on feeder body. Close the magazine cap
slowly until it lock after checking to see that the pin coil
is set properly in the magazine.
Connecting air hose
Slip the air socket of the air hose onto the air fitting on
the nailer. Be sure that the air socket locks firmly into
position when installed onto the air fitting.

OPERATION

CAUTION:
Be sure to set the change lever to the LOCK
•
position to avoid unexpected misfiring when the
tool is not in use.
Make sure all safety systems are in working order
•
before operation.

Only pulling trigger without contact element contacting
workpiece must not bring about the tool firing.

This nailer is only for intermittent pin-driving. Intermittent
pin-driving is a method of pinning piece by piece with
the following step.
1. Set the change lever to the FREE position.
2. Place the contact element against the workpiece
3. And then pull the trigger.
Pin-driving of concrete
WARNING:
Use hardened pins only for concrete.
•
Using other purposed pins may cause serious
injuries. Do not pin directly on the concrete.
Failure to do so may cause concrete fragments to
fly off or pins to strike back, causing serious
injuries.
When driving pins, hold the tool so that it stands
•
upright to the driving surface.
Slanted pin-driving may cause concrete fragments
to fly off or pins to strike back, causing serious
injuries.
Do not use on the surface that objects hang from,
•
such as area where hangers for sewer pipe, dust
pipe etc. are set up
Choose and use pins so that the penetration amount
into concrete ranges 15 mm - 20 mm.
Fig.14
CAUTION:
Use this tool only for soft concrete built up not so
•
long before. Using on the hard concrete may
cause pin bending or pin-driving to insufficient
depth.
When the penetration amount into concrete is
•
required more than 20 mm, driving pins to the
sufficient length may not be obtained. Pins may be
driven too shallow causing unstable workpiece,
resulting in personal injury and damage to property.
Cutting off the sheet
CAUTION:
Always disconnect the hose before cutting off the
•
sheet.
Fig.15
Tear off the output sheet in the direction of the arrow
when using the sheet collated pins.

MAINTENANCE

CAUTION:
Always disconnect the air hose from the tool
•
before attempting
maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
Jammed nailer
CAUTION:
Always disconnect the air hose and remove the
•
pins from the magazine before cleaning a jam.
