HOW TO USE THE NAILER
CAUTION
䡬
Never use the head or body of this device as a
hammer.

2. How to drive nails
This product is a nailer using SINGLE SEQUENTIAL
ACTUATION MECHANISM. If you pull the trigger
first, nothing will happen even if you press the push
lever up against an object.
Depress the nail outlet onto the desired point; then
pull the trigger to drive a nail in a single shot (See
Fig. 11 ).
After nailing once, nailing will not be possible again
until the trigger is released and pressed again.
You cannot drive a nail by first pulling on the trigger
and then pressing the push lever against an object
(continuous nailing).
WARNING:
A nail will fire each time the trigger is depressed as
long as the push lever remains depressed.
CAUTION
Exercise care when nailing corners of lumber, metal
plate or concrete. When continuous nailing corners
of lumber, metal plate or concrete, a nail may go
astray or break through the corner.
NOTE:
䡬
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 bumper, 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.
䡬
After completing operation, put into the body about
2 cc oil through the hose joint to protect the tool from
rust.
䡬
Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
(1) Selecting hardened nails for use with concrete
CAUTION
䡬
Use hardened nails designed for use with concrete.
䡬
Place the nailer vertically over the location into which
the nail is to be driven.
䡬
Do not drive nails into the edge of concrete.
䡬
Do not use the nailer in locations from which other
items are suspended (suspended pipes, etc.).
