to the wrong step, poor nail feed or malfunction of the tool
may result. (Fig. 13)
Place the nail coil over the change plate. Uncoil enough
nails to reach the nail guide. Place the first nail in the
feeder and the second nail in the feed claw. Place other
uncoiled nails on feeder body. After checking to see that
the nail coil is set properly in the magazine, close the
magazine cap slowly and then close the door until it locks.
Connecting air hose
Slip the air socket of the air hose onto the air fitting on the
nailer. Be sure that the air socket locks firmly into position
when installed onto the air fitting. A hose coupling must be
installed on or near the tool in such a way that the
pressure reservoir will discharge at the time the air supply
coupling is disconnected.
Changing the trigger for intermittent
nailing
CAUTION:
• Always disconnect the air hose and unload the tool with
nails before replacing the trigger.
• After the trigger replacement, always check the tool
operates properly before actual work. Do not load the
tool with any nails before checking the function to avoid
unexpected nailing. (Fig. 14)
The trigger for continuous nailing is factory-installed. To
change the nailing mode to intermittent nailing, replace
the switch trigger with the one for intermittent nailing.
(Fig. 15)
1. Turn the lock lever to the "LOCK" position.
2. Push the pin securing the trigger from the urethane
washer side, and then remove the urethane washer by
fingers or flathead screwdriver and so on. Pull the pin
and remove it from the hole in the housing.
3. Set the trigger assembly for intermittent nailing. Turn
the hinged part inward the trigger, and then set the
part to contact the rod of the valve in the housing.
4. Insert the pin to the hole and then secure it by
urethane washer.
5. Connect the air hose, and then check whether the tool
operates properly. Refer to the section "Checking
intermittent nailing mode".
If the tool does not actuate properly, disconnect the air
hose, and then reassemble the trigger according to 1-
4 shown above.
NOTE:
To set back to continuous nailing, follow the procedures
for changing the trigger above.
OPERATION
CAUTION:
• Make sure all safety systems are in working order
before operation.
• When not operating the tool, always lock the trigger by
turning the change lever to the LOCK position.
• Make sure that the trigger is locked when the change
lever is set to the LOCK position.
Checking continuous nailing mode
- The tool must not operate only by connecting the air
hose. (Fig. 16)
- The tool must not operate only by pulling the trigger.
(Fig. 17)
- The tool must not operate only by placing the contact
element against the work piece without pulling the
trigger. (Fig. 18)
- The tool should operate properly when pulling the
trigger first and then place the contact element against
the work piece.
Checking intermittent nailing mode
- The tool must not operate only by connecting the air
hose.
- The tool must not operate only by pulling the trigger.
- The tool must not operate only by placing the contact
element against the work piece without pulling the
trigger.
NOTE:
• The operating conditions shown above are the same
as the operating conditions mentioned in "Checking
continuous nailing mode". (Fig. 19)
- The tool must not operate when pulling the trigger first
and then placing the contact element against the work
piece.
Nailing method (Fig. 20)
1. To drive a nail, you may pull the trigger first and then
place the contact element against the workpiece, or
2. Place the contact element against the workpiece and
pull the trigger. (Fig. 21)
• No. (1) method is for continuous nailing.
No. (2) method is for intermittent nailing, when you
wish to drive a nail carefully and very accurately.
CAUTION:
• However when the tool is set to the "Intermittent
Nailing" mode, WITH THE TRIGGER HELD IN A
HALF-PULLED POSITION, an unexpected nailing
could occur, if contact element is allowed to re-contact
against the workpiece or the other surface under the
influence of recoil.
In order to avoid this unexpected nailing, perform as
follows;
- A. Do not place the contact element against the
workpiece with excessive force.
- B. Pull the trigger fully and hold it on for 1-2 seconds
after nailing.
To prevent the trigger from being accidentally pulled, a
lock-off button is provided. (Fig. 22)
To lock the trigger, turn the lock lever to the "LOCK"
position. (Fig. 23)
To start the tool, turn the lock lever to the "FREE" position.
Nailing of steel plate
WARNING:
• Use 3.2 mm or less steel for C-shaped one.
The tool will bounce severely and a nail struck back,
causing serious injuries.
• Use hardened nails only for steel plate.
Using other purposed nails may cause serious injuries.
