(5) Lock the knob correctly.
NOTE
Be careful not to disengage the nails with the guide
surface.
Otherwise, the nail guide will not close correctly.
CAUTION
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a work
bench or fl oor. Also, never face the nail outlet toward
any part of a person.
NOTE
Before loading the nails in the magazine, position the
nail holder according to the length of the nail. If the nail
holder position is not adjusted properly, nail feed may
jam. If the cover is forcibly closed without adjusting
the position of the nail holder, the nail holder may be
damaged.
HOW TO USE THE NAILER
CAUTION
○ Do not use the body or any portion of the tool as a
hammer as nails may be discharged unexpectedly or
the tool may become damaged and serious injury could
occur.
○ Take precautions to ensure the safety of persons in the
vicinity during operation.
○ Ensure tool is always safely engaged on the workpiece
and cannot slip.
○ Never carry a pneumatic tool by its hose.
○ Never drag a pneumatic tool by its hose.
1. Set the lock lever to "Free" position
Turn the lock lever and align it with the "Free" position
(Fig. 10).
2. How to drive nails
This product is a nailer using SINGLE SEQUENTIAL
ACTUATION MECHANISM. If you pull the trigger fi rst,
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. 12).
After nailing once, nailing will not be possible again until
the trigger is released and pressed again.
You cannot drive a nail by fi rst pulling on the trigger
and then pressing the push lever against an object
(continuous nailing).
WARNING
A nail will fi re 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
○ 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 confi rm 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 about 2 cc
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.
(1) Selecting hardened nails for use with concrete
CAUTION
○ Use hardened nails designed for use with concrete.
○ Place the nailer vertically over the location into which
the nail is to be driven.
○ Do not drive nails into the edge of concrete.
○ Do not use the nailer in locations from which other items
are suspended (suspended pipes, etc.).

NOTE
○ When attaching wood to concrete, test-fi re one nail into
soft concrete. If the concrete is too hard, the nail may
bend or not be driven in suffi ciently.
○ There are cases in which nails will not be properly
driven into concrete with an intrusion level deeper than
15mm or hard concrete.
[When attaching thin steel plates (equally-partitioned
runners) to concrete]
WARNING
Ensure that special nails are used when attaching thick
steel plates to concrete.
Failure to observe this may result in the nail not being
driven into the concrete, or in it bending or ricocheting
out, which may lead to injury.
Thin steel sheets
Concrete intrusion level
of 18 mm to 24 mm.
NOTE
Only use runners or other grooved steel plates when
driving special concrete nails into concrete. Also, as the
material is thin, it is necessary to adjust the depth with
the adjustor to ensure that it is equal with the surface
