9. MAINTAINING THE DSP

●

Before you service the

DSP

, carefully read pages 2 through 5, Chapter 1 “SAFETY.”

●

Before you service the

DSP

, disconnect the power; otherwise you may receive an electric shock.

●

Before you remove or disassemble a bolt, pipe, or any other part of the

DSP

, stop it, disconnect the

power, and make sure that the internal pressure has dropped to an atmospheric pressure. Otherwise
the compressed air may gush out of the

DSP

Overhauling consists changing the existing air end
with a new replacement air end.
Overhaul the

DSP

at 6 yearly.

9.1 Air Compressor Maintenance

①

The

DSP

standard maintenance schedules are listed

in pages 71 through 74. Periodic maintenance inter-
vals in these schedules mean daily, monthly, halfyear-
ly, yearly, two-yearly, 4-yearly, and 6-yearly.

They are based on the normal environmental and

operating conditions. If your

DSP

is in sever environ-

mental and operating conditions, service it at more
frequent intervals.

Standard maintenance schedule (A) is based on the

8,000 operating hours per year while (B) 4,000 hours.
Select either (A) or (B) according to your own operat-
ing hours per year. If your

DSP

is in sever (high-

humid, dusty, etc.) conditions, however, always select

(A) regardless of your operating hours.

②

Any of the maintenance intervals is not a warranty

period.

③

If the part you inspected is abnormal, faulty, or dam-

aged, replace it.

④

Do not neglect a yearly maintenance schedule as it is

most important from a preventive maintenance stand-
point.

⑤

Use HITACHI genuine parts for replacement.

(1) Daily fill the

OPERATION RECORD LOGBOOK

(

p. 88 - 89) and check the operating data and

conditions.

If the data deviates from the benchmark in the

logbook, service the

DSP

(2) Regularly drain the condensate and observe the other

daily operating instructions; see pages 6 through 7.
