OPTIONAL ACCESSORY
Sequential Trip Mechanism Kit (Code No.876762)
(Sequential Fire Parts Set, Single Shot Parts)
With the sequential fire parts,the nail is driven only

PREPARATION PRIOR TO OPERATION
1. Prepare the hose
Be sure to use the hose provided with minimum
6 mm (1/4") 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. Lubrication
(1) Prior to operating this nailer, be sure to provide an air
set between the air compressor and this device.
Lubrication through the air set offers smooth operation,
extended service life, and anticorrosion.
