Hitachi HISCREW 2000 Series Instruction Manual page 5

WARNING
ROTATING PARTS!
Return any detached cover to its original
place before starting the air compressor.
Keep your hands and any objects away from
the incoming-air louvers because the cooling
fan is underneath.
Keep your hands/face and any objects away
from the outgoing-air louvers.
WARNING
ROTATING PARTS!
Keep your hands and any objects away from the
rotating parts (belts, pulleys, etc.).
Be careful on the stopped air compressor in an
automatic stop/restart control because it may
restart without pressing the START button.
CAUTION
USE THE GENUINE SYNTHETIC OIL ONLY.
Always use the "NEW AOIL 2000"
(Hitachi's genuine synthetic oil) for the air
compressor. Do not mix it with any other
brands of oil.
Replace the oil regularly as scheduled by the
Instruction Manual.
WARNING
HOT OIL UNDER PRESSURE!
Before replacing the oil, stop the air compressor,
disconnect the power, and make sure that the
discharge pressure gauge reads 0 (zero) MPa.
Be careful on the stopped air compressor in an
automatic stop/restart control because it may
restart without pressing the START button.
1. TO USE IN SAFETY
WARNING
RESPIRATORY DISEASES!
Do not use the air compressor for a direct-breath
application. Failure to observe this may cause
hazards (respiratory diseases etc.) as the com-
pressed air from the air compressor contains oil
particles.
It may also cause hazards to operate the air com-
pressor in a badly ventilated room, tunnel, etc.
WARNING
HOT OIL OR AIR UNDER PRESSURE!
Before replacing the oil or servicing the air com-
pressor, stop the air compressor, disconnect the
power, and make sure that the discharge air pres-
sure gauge reads 0 (zero) MPa. Be careful on the
oil filling port plug, the relief valve, etc. because
the hot pressurized oil or air may gush from these
parts.
WARNING
FLAMMABLES!
Keep a container of the flammable hazards (sol-
vents etc.) away from the air compressor. Fail-
ure to observe this may cause it to explode.
Do not use any brands of oil other than "NEW
A OIL 2000" (Hitachi's genuine syn-
thetic oil). Replace the oil and the oil separator
(element and housing) regularly as scheduled
by the Instruction Manual. Failure to observe
these may deteriorate the oil and eventually
cause a fire and/or explosion.
WARNING
ROTATING PARTS!
Keep your hands and any objects away from the
rotating parts (pulleys, belts, cooling fans, etc.).
Be careful on the stopped air compressor in an
automatic stop/restart control because it may
restart without pressing the START button.
WARNING
LIVE CIRCUITRY!
Before servicing or wiring the air compressor,
disconnect the power to avoid an electric shock.
Also, put a notice saying 'Men at Maintenance
Work. Do not turn on the switches.' on the power
supply, and thereby prevent someone from care-
lessly turning on the switches.
Ask a qualified electrician for wiring and any other
electrical works.
Ground the air compressor.
CAUTION
FIRE!
Do not use fire around the air compressor. Oth-
erwise, the sparks from the fire may cause the
air compressor to be internally burnt.
Do not remove any protective relays on the air
compressor. Also, do not make a modification
of the control circuit that will result in impairing
the protective relay's function. Otherwise, a fire
may occur and/or the air end may be burnt.
Install an earth leakage fuse free breaker on
the power supply.
Check the oil level gauge and verify that the oil
level is between the upper and lower red lines.
CAUTION
HOT!
Do not touch the air compressor when it is op-
erating or immediately after you have stopped
it, because its components and the oil are hot.
Keep your hands/face away from the outgoing-
air louvers because the hot air is exhausted from
the louvers.
