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.
Adjust the oiler so that a single drop of oil is supplied
at intervals of 5 to 10 nailing cycles.
(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix
two or more types of different oils.
3. Load nails
(1) Depress the magazine stopper and open the cover to
load nails, being sure to insert the end of the nail-
linking band into the magazine opening to facilitate
subsequent procedures. (See Fig. 1)
(2) Close the cover after confirming that the nails are
loaded in the magazine.
(3) Grip the nail guide and knob with the fingers. Then
depress the knob to open the nail guide towards the
left. (See Fig. 2)
(4) Extend the nail line from the magazine. Insert the first
nail between the two pawls of main feeder so that the
nail head is passed into the guide slot.
To close smoothly the nail guide, never insert the first
nail in front of the pawl of main feeder. (See Fig. 3)
(5) Grip the nail guide and knob. Then depress the knob
and turn the nail guide to the right. Nails are loaded by
adopting the above procedures.
CAUTION
To prevent unitentional operation, never touch the
trigger or place the top end of the push lever on a work
bench or floor. Also, never face the nail outlet toward
any part of a person.
