Adjusting the adjuster (Fig. 12)
Carry out test driving. If the nails are too deep, turn
the adjuster to the shallow side (
If the nail depth is too shallow, turn the adjuster to
the deep side (
mark) (See Fig. 12, 13).
Depth is changed 1 mm with each rotation of the
adjuster.
NOTES
When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a nail goes
down. Do not rotate the adjuster by force beyond
that point.
The nail-driving depth can also be adjusted by
changing the air pressure used. Carry this out together
with movement of the adjuster. Using a high air
pressure that does not match the nail-driving
resistance will shorten the life of this nailer.
3. How to use nosecap
CAUTION
Remove the hose from the nailer and release the
compressed air before installing or removing the
nosecap to prevent accidental nail ejection.
Attach the nose cap on the tip of the push lever when
you wish to protect the surface of wood, etc., from
scratches.
(1) Attaching and detaching nose cap
The nose cap can be attached by simply pressing it
into the push lever.
Press it in until a convex part inside the nose cap
enters into a hole of the push lever (Fig. 14).
For removal, insert a thin rod such as a screw driver
into the gap on the back of the push lever, and then
pull it out.
(2) Safekeeping of nose cap
Put the removed nose cap in a space behind the
magazine for safekeeping (Fig. 15).
INSPECTION AND MAINTENANCE
CAUTION
Be sure to disconnect the hose during cleaning jams,
inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) Remove the nail roll from the magazine, open the
nail guide, insert a rod into the outlet and tap the rod
with a hammer (Fig. 16).
(2) Remove the jammed nail with slotted screwdriver
(Fig. 17).
(3) Cut off the defective part of the steel wire which links
the nails with cutting nippers, correct the deformation,
then load the nail roll in the magazine.
(4) In case of frequent jams, consult the Authorized
Service Center from which you bought this machine.
2. Check on mounting screws for each part
At regular intervals check every part for loose
mounting screws and whether or not there are any
air leaks. Retighten any loose screws. Operating the
equipment with loose screws untightened will incur
a hazard.
3. Inspecting the push lever
Check if the push lever can slide smoothly (Fig. 18).
Clean up the sliding area of the push lever and use the
provided oil for lubrication from time to time.
Lubrication enables smooth sliding and simultaneously
serves to prevent the formation of rust.
4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then
mark).
apply the recommended oil (See Fig. 19).
(2) Open the nail guide and remove dust, etc., as shown
in Fig. 20. Apply lubricant to the sliding groove of the
feeder and shaft. Check the nail stopper (A) and nail
stopper (B) slide smoothly by pushing them with
your finger.
(3) Also, apply the recommended oil to the feeding
surface of the nose and nail guide after cleaning. This
promotes smooth operation and retards corrosion.
CAUTION
Check for smooth movement of the feeders and
stoppers before use. If movement is uneven, nails
could be fired at an irregular angle, presenting a
hazard to the operator and others nearby.
5. Inspecting the magazine
Clean the magazine. Remove dust of wooden chips
which may have accumulated in the magazine.
6. Storing
When not in use for an extended period, apply a thin
coat of the lubricant to the steel parts to avoid rust.
Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area.
When not in use, the Nailer should be stored in a
warm and dry place.
Keep out of reach of children.
7. Service parts list
CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without
prior notice.
COMPRESSOR
CAUTION
When the maximum, operating pressure of the air
compressor exceeds 8.3 bar (120 psi.), be sure to
provide a reducing valve between the air compressor
and nailer. Then, adjust the air pressure within the
operating range of 4.9 – 8.3 bar (70 – 120 psi.). If the
air set is installed, lubrication is also possible, thus
providing additional convenience.
OILER-FILTER-REDUCING VALVE (Air Set)
So that the equipment can be operated under an optimum
condition to ensure extended service life, it is advisable
to use an oiler filter reducing valve. Please limit the
length of the hose between the unit and the air set to
within 10m when using (Fig. 21).
