OPERATION
WARNING:
•
Do not touch around the exhaust vent.
The surface
will be very hot during or after an operation. Touching
around the exhaust vent may cause burns or injuries.
CAUTION:
•
Make sure all safety systems are in working
order before operation.
Checking proper action before operation
Before operation, always check following points.
— Make sure that the tool does not operate only by
installing the battery cartridge and fuel cell.
— Make sure that the tool does not operate only by
pulling the trigger.
— Make sure that the tool does not operate only by
placing the contact element against the workpiece
without pulling the trigger.
— Make sure that the tool does not operate when
pulling the trigger first and then placing the contact
element against the workpiece.
Driving nails

Fig.18
1. To drive a nail, place the contact element against
the workpiece.
The fan motor is activated, fuel gas is injected
into combustion chamber and mixed with air by
the fan.

Trigger
2. Hold the contact element pressing firmly and pull
the trigger.
Fuel gas is combusted and the nail is driven.
3. Further driving can be initiated only after both the
contact element and the trigger are released.
Nail-driving of concrete
WARNING:
•
Use hardened nails only for concrete.
Using other purposed nails may cause serious
injuries. Do not nail directly on the concrete.
Failure to do so may cause concrete fragments
to fly off or nails to strike back, causing serious
injuries.
•
When driving nails, hold the tool so that it stands
upright to the driving surface.
Slanted nail-driving may cause concrete frag-
ments to fly off or nails to strike back, causing
serious injuries.
•
Do not use the tool on the surface that objects
hang from, such as area where hangers for
sewer pipe, dust pipe etc. are set up
CAUTION:
•
Use this tool only for soft concrete built up not
so long before. Using on the hard concrete may
cause nail bending or nail-driving to insufficient
depth.
•
When the penetration amount into concrete is
required more than 20 mm, driving nails to the
sufficient length may not be obtained. Nails may
be driven too shallow causing unstable work
-
piece, resulting in personal injury and damage
to property.
•
When driving nail directly onto hard surfaces
such as steel and concrete, press the contact
element firmly against the workpiece to prevent
slipping.
Choose and use appropriate nails so that the penetra-
tion amount into concrete ranges 15 mm - 20 mm.

Anti dry fire mechanism
This mechanism prevents the tool from firing without
nail.
Dry fire prevention automatically functions when the
rest of nails get to the last 2-3 pieces.
