OPTIONAL ACCESSORY
Sequential Fire Parts Set (Code No.881-012)
With the sequential fire parts,the nail is driven only
by squeezing the trigger after pushing down the
push lever.
By installing these parts, driving nails into improper
positions and unexpected firing of nails caused by
accidental operation of the push lever can be pre-
vented.
APPLICATIONS
Construction – retaining various types of internal
materials.
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 pres-
sure 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. Lubri-
cation 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. Loading nails
(1) Open the nail guide and the cover.
Place your finger on the nail guide and the knob. Push
the knob downward and open the nail guide to the left
(see Fig. 2).
(2) Insert nails in the magazine.
Adjusting the nail holder.
Pull the nail holder out in your direction and insert in
either the upper or lower groove. Insert in the upper
side when using nails that are 32 mm (1-1/4") or 38 mm
(1-1/2") in length.
Insert in the lower side when using nails that are 45
mm (1-3/4") or 50 mm (2") in length (see Fig. 3).
Insert the nails in the magazine (see Fig. 4).
CAUTION
Before inserting the nails in the magazine, be sure to
adjust the nail holder to a position that is appropriate
to the length of the nails you are using. Using the
nailer set at the wrong position will cause problems
with transfer of nails.
(3) Loading the nails in the nail guide.
Pull the first section of the nails from the magazine.
While pressing the sheet to the guide surface, insert
the first nail into the driving hole and the second nail
between feeder (A) and feeder (B).
Insert the nail so that the nails head and the upper side
sheet engage the guide slot (Fig. 5, 6).
