7-4. Precautions in Operation
(1) Pay special attention to the pressure, capacity and piping of the air compressor in order to keep the air
pressure supplied to the Model NV 83A2 within the range from 5 kgf/cm
2
(70 psi, 4.9 bar) to 8.5 kgf/cm
2
(120 psi, 8.3 bar). Otherwise, ill effect may be given to the performance, service life and safety of the Model
NV 83A2. (Be sure to install a regulator when using a high-pressure air compressor whose set pressure is
10 kgf/cm
2
(140 psi, 9.8 bar) or more. In this case, adjust the air pressure at 8.5 kgf/cm
2
(120 psi, 8.3 bar) or
less.)
(2) If dust in the compressed air settles on the sliding portion, the Model NV 83A2 will not operate properly.
Lubrication is effective to remove dust and also to prolong the service life of the Model NV 83A2 keeping good
performance. It is recommended to lubricate the Model NV 83A2 daily. Supply 5-10 drops of lubricant into the
air plug on the Model NV 83A2.
When not in use for an extended period, supply lubricant and perform idle driving two or three times to
lubricate the inside, then apply a thin coat of the lubricant to the steel parts to avoid rusting.
Usable lubricant is specified in the following table. Please recommend the customers to use Hitachi nailer/
tacker oil.
(3) Be sure to drain the tank of the compressor securely to prevent deteriorated performance or malfunction of the
Model NV 83A2 due to rusting.
(4) Instruct the customers (especially the heavy users) to perform inspection and maintenance securely.

7-3. Related Laws and Regulations
As nailers and staplers are designed to instantaneously drive nails and staples, there is an ever-present danger of
misfiring and subsequent possible serious injury. Accordingly, close attention in handling is absolutely necessary
at all times. Carefully ensure that the customer is fully aware of the precautions listed in the Instruction Manual
provided with each unit.
While there are no specific safety regulations, there are related items in various general safety regulations with
which the salespersons should be familiar in order to properly advise the customer. Please check your national
and/or local regulations for applicable items. Some applicable items are outlined below.
