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. If your unit is for use on less than 150 volts, it has a plug that looks like that shown in sketch (A) in Figure on the right. An adapter, see sketches (B) and (C), is available for connecting sketch (A) type plugs to two-prong receptacles. The green-colored rigid ear, lug, or the like extending from the adapter must be connected to a permanent ground, such as a properly grounded outlet box.

Note: The grounding adaptor, sketch (C), is prohibited in Canada by Canadian Electrical Code Part 1. Therefore, the instructions for its use are not applicable in Canada.

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.

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.

APPLICATIONS

○ Air source of the pneumatic nailer and stapler.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.

2. Power switch

Ensure that the knob of the pressure switch is in the "OFF" position. If the plug is connected to a receptacle while the knob is in the "ON" position, the compressor will start operating immediately and can cause serious injury.

3. Extension cord

When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity (refer page 6). The extension cord should be kept as short as practicable.

WARNING: Damaged cord must be replaced or repaired.

4. Confirm the power receptacle

If the power receptacle only loosely accepts the plug, the receptacle must be repaired. Contact the nearest electric store for repair service.

If such a faulty receptacle is used, may cause overheating, resulting in a serious hazard.

5. Air coupler installation

Screw in the air coupler to the joint (Refer to Fig. 1 and Fig. 2). The screw size of the joint is 3/8". Use an air coupler which has the same screw size.

OPERATION

1. Start up

Insert the plug into the receptacle and start the compressor by pulling the knob of the pressure switch to "ON". (Refer to Fig. 1 and Fig. 2).

WARNING: Do not stop or start the compressor by use of the plug. Always use "ON/OFF" knob located on the pressure switch.

The operation of the compressor is automatic and is controlled by the pressure switch which stops it when the pressure in the air-tank reaches the maximum level and restart it when the air pressure drops during use to the restart level. The motor of the compressor is fitted with a thermal protection inside-the wrap, which stops the compressor when the temperature is too high. Should this be tripped, the compressor will restart automatically after 15–20 minutes.

2. Adjustment of working pressure

Unlock the knob of the pressure reducer pulling it up, adjust the pressure to the required level by turning the knob clockwise to increase and counterclockwise to decrease.

A pressure gauge is provided to know when the required pressure is reached, lock the knob by pushing it down firmly (Fig. 2).

When adjusting the pressure, check and make sure that a pressure gauge for the tank has the pressure level that is higher than that of the pressure to be adjusted.

It is also imperative that you make adjustment by slowly starting up the pressure from the level that is lower than the pressure to be adjusted.

WARNING: Check the manufacturer's maximum pressure rating for nailers, staplers and accessories. Compressor outlet pressure must be regulated so as to never exceed the maximum pressure rating of the nailers, staplers and accessories.
