OPERATION

CAUTION:
Make sure all safety systems are in working order
•
before operation.
1. To drive a nail, you may place the contact element
against the workpiece and pull the trigger, or

Fig.14
2. Pull the trigger first and then place the contact
element against the workpiece.
No. 1 method is for intermittent nailing, when you
•
wish to drive a nail carefully and very accurately.
No. 2 method is for continuous nailing.
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.
For No. 1 method, set the change lever to
•
the position.
For No. 2 method, set the change lever to
the position.
After using the change lever to change the nailing
method, always make sure that the change lever is
properly set to the position for the desired nailing
method.

Anti dry fire mechanism
This tool is equipped with an anti dry fire mechanism.
When there are a few nails remaining in the magazine,
the contact arm will be locked in the undepressed
position to prevent the tool from being activated. Load
more nails to resume operation.
Jammed nailer
Fig.16
CAUTION:
Always lock the trigger, disconnect the hose and
•
remove the nails from the magazine before clearing
a jam.
When the nailer becomes jammed, do as follows:
Insert a small rod or the like into the ejection port and tap
it with a hammer to retract the driver.
Use pliers to bend the jammed nail so that the nail head
comes out of the slot in the driver guide. Then remove
the jammed nail.
