PREVENTIVE MECHANISM FOR
UNLOADED OPERATION
The machine employs a preventive mechanism for
unloaded operation.
The machine enters a state where the push lever stopper
runs into the upper part of the push lever and the push
lever cannot be pushed up. This takes place when the
magazine is not loaded with nails or when the remaining
number of nails becomes less than 5 (This differs by the
type of nail).
Load the nails immediately if you come across with such a
condition during operation.

CAUTION
Use caution not to throw the push lever tip onto
wood and the like while the push lever stopper is in
the upper part of the push lever.
METHODS OF OPERATION
This Nailer is equipped with the push lever and does not
operate unless the push lever is depressed (upward
position).
There are two methods of operation to drive nails with
this Nailer.
They are :
1. Intermittent operation (Trigger fire) :
2. Continuous operation (Push lever fire) :
(1) Intermittent operation (Trigger fire)
Use the SINGLE ACTUATION MECHANISM setting.
WARNING
Unlike the FULL SEQUENTIAL ACTUATION
MECHANISM, please note that the SINGLE
ACTUATION MECHANISM of this Hitachi nailer
will drive a nail each time the push lever is
pressed against the wood as long as the trigger is
pressed.
For intermittent operation, set the switching
device to the upward position completely. (i.e.
Set to SINGLE ACTUATION MECHANISM.)
To avoid double firing or accidental firing due to
recoil.
1) Set the switching device to SINGLE
ACTUATION MECHANISM.
2) Pull the trigger rapidly and firmly.
1 Set the switching device to the upward position
(to set to SINGLE ACTUATION MECHANISM).
(Set the switching device to the upward position
completely as shown in the diagram. Otherwise, it
will be set to CONTACT ACTUATION
MECHANISM.)
2 Position the nail outlet on the workpiece with
finger off the trigger.
3 Depress the push lever firmly until it is completely
depressed.
4 Pull the trigger to drive a nail.
5 Remove finger from the trigger.
To continue nailing in a separate location, move the
nailer along the wood, repeating steps 2 - 5 as
required.

(2) Continuous operation (Push lever fire)
Using CONTACT ACTUATION MECHANISM
To avoid double firing or accidental firing due to
recoil.
1) Do not press the nailer against the wood with
excessive force.
2) Separate the nailer from the wood as it recoils
after nailing.
1 Set the switching device to the downward position
(to set to CONTACT ACTUATION MECHANISM).
(Set the switching device to the downward
position completely as shown in the diagram.
Otherwise, it will not operate properly.)
2 Pull the trigger with the Nailer off the workpiece.
3 Depress the push lever against the workpiece to
drive a nail.
