Adjusting The Nailing Depth; Using The Blow Nozzle - Hitachi NT 50A5 Instruction And Safety Manual

3) supply 5 – 10 drops of Hitachi pneumatic tool
lubricant into the air plug on the Nailer; and
4) open the petcock on the air compressor
tank to drain any moisture.

ADJUSTING THE NAILING DEPTH

● When adjusting the Adjuster, be sure to
remove your fi nger from the trigger and
disconnect the air hose from the nailer.
To assure that each nail penetrates to the same depth, be
sure that:
1) the air pressure to the Nailer remains constant
(regulator is installed and working properly), and
2) the Nailer is always held fi rmly against the workpiece.
If nails are driven too deep or shallow into the workpiece,
adjust the nailing in the following order.
1 DISCONNECT AIR HOSE FROM NAILER.

2 If nails are driven too deep, turn the adjuster to the
shallow side.

If nails are driven too shallow, turn the adjuster to the

3 Stop turning the adjuster when a suitable position is
reached for a nailing test.

5 DISCONNECT AIR HOSE FROM NAILER.
6 Choose a suitable position for the adjuster.
NOTE
● The nail might not drive deep enough if using high
pressure with the adjuster set upwards (shallow side)
due to factors such as the material hardness or nail
type.
If that happens, reduce pressure and set the adjuster
to lowest position so the nail drives in at a good
position.

USING THE BLOW NOZZLE

● Be sure to release your fi nger from the trigger
before using the blow nozzle.
● Do not point the air outlet of blow nozzle at a
person.
● Do not use the blow nozzle when depress the
push lever against the workpiece.
This Nailer has a blow nozzle that blows out wood
shavings which occur during work.
Press the knob with your thumb to use the blow nozzle, as
shown in the fi gure.

NOTE
● When the blow nozzle is used for a long time, the
nailing force may degrade temporarily. In this case,
allows the air supply pressure to stabilize before
starting work.
● Oil in the body or drained water from the compressor
can sometimes spout out of the air outlet of blow
nozzle. It is recommended that you once conduct a
test before use and see if such phenomenon happens
at an environment where spouted oil will cause any
inconvenience.
