APPLICATIONS
Construction wooden works such as floor and wall
framing, roof decking and subflooring.
Mobile and modular home construction.
Making wooden boxes, palletes, and drums.
Packing operations in manufacturing plants, and other
types of packing and crating work in general.
PREPARATION PRIOR TO OPERATION
1. Prepare the hose
Be sure to use the hose provided with minimum 8.5
mm (11/32") inside diameter.
NOTE
The air supply hoses must have a minimum working
pressure rating of 12.8 bar (180 psi) or 150 percent of
the maximum pressure produced in the air supply
system, whichever is higher.
2. Check on safety
CAUTIONS
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the exhaust
cover, etc. for tightness.
Check the nailer for air leaks and defective or rusty
parts.
Check whether or not the push lever works correctly.
Also check whether or not any dirt has adhered to the
moving parts of the push lever.
Recheck on operational safety.
BEFORE USE
1. Check the air pressure
CAUTION
The air pressure must be constantly maintained at
4.9 – 8.3 bar (70 – 120 psi.).
Adjust the air pressure between 4.9 to 8.3 bar (70 ~
120 psi.) according to the diameters and length of
nails and hardness of the wood being nailed. Pay
special attention to the output pressure, capacity,
and piping on the air compressor, so that air pressure
does not exceed the specified limit. Note that
excessive pressure may affect overall performance,
service life, and safety.
2. Lock mechanism of the trigger
This device has a lock mechanism to prevent the
trigger from pulling.
Set the lock lever to "Lock" position to lock the trigger
in place.
