APPLICATIONS
○ Construction wooden works such as fl oor and wall
framing, roof decking and subfl ooring.
○ 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
Use an air hose designed for high-pressure operation.
Be sure to use the hose provided with minimum 5 mm
(13/64") inside diameter.
NOTE
The air supply hoses must have a minimum working
pressure rating of 29.4 bar (420 psi) .
Piston reciprocating
12 – 23 bar (170 – 320 psi.)

2. Check on safety
CAUTION
○ Unauthorized persons (including children) must be kept
away from the equipment.
○ Wear eye protector.
○ Check the retaining screws which fi x 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
Use a compressor designed for high-pressure
operation.
The air pressure must be constantly maintained at 12 –
23 bar (170 – 320 psi.).
Adjust the air pressure between 12 to 23 bar (170 – 320
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 specifi ed limit. Note that excessive pressure
may aff ect 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.
To drive a nail, turn the lock lever to the "Free" position.
When not driving nails set the lever to the "Lock"
position (Fig. 2).
CAUTION
Keep the trigger locked at all times except when driving
nails.
3. Lubrication
(1) Be sure to lubricate this nailer at least twice a day. To
lubricate, pour 10 to 15 drops of oil into the air plug
before and after using this nailer. The oil applied before
use lubricates this nailer; the oil applied after use
prevents rust.
(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix two
or more types of diff erent oils.
4. Nose Selection and Switching
This nailer allows you to switch the nail outlet between
two sizes to extend the range of usable types and sizes
of nails. Set the nose switch lever to select the outlet
size matching the head diameter of the nail to be used
as shown below (Fig. 3).
