— 3 —
16. CHECK DAMAGED PARTS AND AIR LEAK.
Before further use of the compressor, a guard or
other part is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts,
mounting, air leak, and any other conditions that may
affect its operation.
24. USE ONLY GENUINE HITACHI REPLACEMENT PARTS.
Replacement parts not manufactured by Hitachi may
void your warranty and can lead to malfunction and
resulting injuries. Genuine Hitachi parts are available
from your dealer.
25. DO NOT MODIFY THE COMPRESSOR.
Do not modify the compressor. Always contact the
Hitachi authorized service center any repairs.
Unauthorized modification may not only impair the
compressor performance but may also result in
accident or injury to repair personnel who do not have
the required knowledge and technical expertise to
perform the repair operations correctly.
A guard or other part that is damaged should be
properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this
Instruction Manual.
Have defective pressure switches replaced by
authorized service center.
Do not use compressor if switch does not move it on
and off.
26. PUSH THE KNOB OF THE PRESSURE SWITCH TO OFF
WHEN THE COMPRESSOR IS NOT USED.
17. NEVER USE COMPRESSOR FOR APPLICATIONS
OTHER THAN THOSE SPECIFIED.
When the compressor is not used, push the knob of
the pressure switch OFF, disconnect it from the power
source and open the drain cock to discharge the
compressed air from the air tank.
Never use compressor for applications other than
those specified in the Instruction Manual.
18. HANDLE COMPRESSOR CORRECTLY.
27. NEVER TOUCH HOT SURFACE.
To reduce the risk of burns, do not touch tubes, heads,
cylinder and motors.
Operate the compressor according to the instructions
provided herein. Never allow the compressor to be
operated by children, individuals unfamiliar with its
operation or unauthorized personnel.
28. DO NOT DIRECT AIR STREAM AT BODY.
Risk of injury, do not direct air stream at persons or
animals.
19. KEEP ALL SCREWS, BOLTS AND COVERS TIGHTLY
IN PLACE.
Never use compressed air for breathing or respirators.
Keep all screws, bolts, and covers tightly mounted.
Check their conditions periodically.
29. DRAIN TANK.
Risk of bursting. Water will condense in the air tank. If
not drained, water will corrode and weaken the air
tank causing a risk of air tank rupture.
Drain tank daily or after 4 hours of use.
To drain tank open valve slowly and tilt compressor to
empty accumulated water.
20. KEEP MOTOR AIR VENT CLEAN.
The motor air vent must be kept clean so that air can
freely flow at all times. Check for dust build-up
frequently.
21. OPERATE COMPRESSOR AT THE RATED
VOLTAGE.
30. DO NOT STOP COMPRESSOR BY PULLING OUT
THE PLUG.
Operate the compressor at voltages specified on their
nameplates.
If using the compressor at a higher voltage than the
rated voltage, it will result in abnormally fast motor
revolution and may damage the unit and burn out the
motor.
This could result in damage to the unit.
Use the “ON/OFF” knob of pressure switch.
31. MAKE SURE THE COMPRESSOR OUTLET PRESSURE
IS SET LOWER THAN THE MAXIMUM OPERATING
PRESSURE OF THE TOOL.
22. NEVER USE A COMPRESSOR WHICH IS DEFECTIVE
OR OPERATING ABNORMALLY.
Too much air pressure causes a hazardous risk of
bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The
regulator outlet pressure must never exceed the
maximum pressure rating.
If the compressor appears to be operating unusually,
making strange noises or vibration, or otherwise
appears defective, stop using it immediately and
arrange for repairs by a Hitachi authorized service
center.
32. DO NOT ATTEMPT TO OPERATE THIS
COMPRESSOR WITHOUT FIRST ADDING OIL TO THE
CRANKCASE. (only for EC12)
23. DO NOT WIPE PLASTIC PARTS WITH SOLVENT.
Solvents such as gasoline, thinner, benzine, carbon
tetrachloride, and alcohol may damage and crack
plastic parts. Do not wipe them with such solvents.
Wipe plastic parts with a soft cloth lightly dampened
with soapy water and dry thoroughly.
The compressor is shipped without oil in the
crankcase.
Serious damage can result from even limited
operation unless filled with oil and broken in correctly.
Make sure to closely follow initial prior to operation
procedures.
— 4 —
33. THE SAFETY VALVE MUST WORK PROPERLY.
Risk of bursting. Before starting the compressor pull
the ring on the safety valve to make sure the valve
moves freely. If the safety valve does not work
properly, over-pressurization may occur, causing air
tank rupture or an explosion.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
Repairs should be conducted only by a Hitachi authorized service
center.
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with a
three-conductor cord and three-prong grounding type plug to fit the
proper grounding type receptacle. The green (or green and yellow)
conductor in the cord is the grounding wire. Never connect the
green (or green and yellow) wire to a live terminal.
We recommend that you never disassemble the compressor or try to
do any rewiring in the electrical system. Any repairs should be
performed only by HITACHI Service Centers or other qualified service
organizations. Should you be determined to make a repair yourself,
remember that the green colored wire is the “grounding” wire. Never
connect this green wire to a “live” terminal. If you replace the plug on the
power cord, be sure to connect the green wire only to the grounding
(longest) prong on a 3-prong plug.
If in doubt, call a qualified electrician and have the receptacle checked
for ground.
— 5 —
EXTENSION CORD
Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept the
compressor’s plug. Replace or repair damaged cord.
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Table shows the correct size to use depending on cord length and name plate ampere rating. If in doubt, use
the next heavier gage. The smaller the gage number, the heavier the cord.
