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.

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.
