Before Use - Hitachi NT 65M2 Handling Instructions Manual

PREPARATION PRIOR TO OPERATION
1. Prepare the hose
Be sure to use the hose provided with minimum
6 mm inside diameter.
NOTE
The air supply hoses must have a minimum working
pressure rating of 12.8 bar or 150 percent of the
maximum pressure produced in the air supply
system, whichever is higher.
2. Check on safety
CAUTIONS
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the exhaust
cover, etc. for tightness.
Check the nailer for air leaks and defective or rusty
parts.
Check whether or not the push lever works correctly.
Also check whether or not any dirt has adhered to
the moving parts of the push lever.
Recheck on operational safety.

BEFORE USE

1. Check the air pressure
CAUTION
The air pressure must be constantly maintained at
4.9 – 8.3 bar.
Adjust the air pressure between 4.9 to 8.3 bar
according to the diameters and length of nails and
hardness of the wood being nailed. Pay special
attention to the output pressure, capacity, and piping
on the air compressor, so that air pressure does
not exceed the specified limit. Note that excessive
pressure may affect overall performance, service
life, and safety.
2. Lubrication
(1) Prior to operating this nailer, be sure to provide an
air set between the air compressor and this device.
Lubrication through the air set offers smooth
operation, extended service life, and anticorrosion.
Adjust the oiler so that a single drop of oil is
supplied at intervals of 5 to 10 nailing cycles.
(2) It is recommended using the recommended oil
(SHELL TONNA). Other applicable oils are listed.
Never mix two or more types of different oils.
3. Load nails
(1) Pull the nail feeder until the concave portion of the
magazine cover clicks. (See Fig. 2)

(3) 1 While holding the nail feeder adjust the magazine
cover in place.
2 Slide the nail feeder slowly forward until it
contacts nails.
NOTE
Use nails at least 5 nails remaining.

If the nail feeder is released roughly, it may be stuck
between the magazine and nails, which makes mis-
feeding trouble.

(1) do not pull trigger;
(2) do not depress push lever; and
(3) keep Nailer pointed downward.
