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
For retaining various types of internal materials.
For retaining various types of sheet metal (thickness
of 0.35 mm (.014") or less).
General construction operations.
CAUTION
To avoid accidents when working with wood or sheet
metal, be sure to use the special linked nails for wood
and sheet metal. Never work with more than a maxi-
mum of three layers of materials with an individual
thickness of 0.35 mm (.014"). Working with four or
more layers at a time is dangerous.

(.181") (.205")
1.6 mm 2.0 mm
(.063") (.079")
Copper nails should be used only for copper sheet or of
driving into soft materials. Work with a maximum of
two sheets of copper plate at a thickness 0.35 mm
(.014"). Never work with three or more sheets at a time.
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 atten-
tion 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. 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) Load nails in the magazine
Grip the nail guide and knob with fingers. Then
depress the knob to open the nail guide towards
the left (See Fig. 2).
Adjust the position of the nail holder according to the
length of the nail (Fig. 3).
For adjustment, turn the nail holder 1 counterclockwise
about 90 degrees. Move the nail holder 2 up and
down, adjust to the length of a nail to be used, and
adjust the surface of the nail holder to the marked
position of the magazine.
Turn the nail holder 3 clockwise (about 90 degrees)
until it goes click (Fig. 4).
