CAUTION:
This tool will sometimes fire twice in rapid succession
when strongly pressed flush against a surface or when
using on hard materials. In such cases, fire the nails
by squeezing and quickly releasing the trigger.
(2) Push lever
When depressing the nail outlet, be sure to fully lift
the push lever (See Fig. 6) to release the safety lock.
Thus, nails cannot be driven without releasing the
safety lock even though the trigger is pulled.
(3) Continuous nailing
First, pull the trigger. Then depress the devise onto
the desired position to automatically drive nails. (See
Fig. 7).
Previously pull the trigger

CAUTION:
Excercise care when nailing corners of lumber. When
continuous nailing corners of lumber, a nail may go
astray or break through the corner.
Do not drive a nail on another nail.
Do not drive a nail on metal parts.
NOTES:
Precautions on no-load operation
Sometimes nailing will continue after driving in all
nails previously contained in the magazine.
This is termed "no-load operation". Such operation
may deteriorate the damper, magazine, and nail
feeder.
To avoid no-load operation, occasionally confirm the
amount of remaining nails. On the other hand, all nails
should be removed after using this nailer.
After completing operation, put into the body 5–10
drops oil through the hose joint to protect the tool
from rust.
Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
