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
