Westward Operating Instructions and Parts Manual

Model 3JR70A

Portable Air Compressor

BEFORE FIRST START-UP

Serious damage

may result if the

following break-in instructions are

not closely followed.

This procedure is required

before the

air compressor is put into service and

when the check valve or a complete

compressor pump has been replaced.

1. Make sure the On/Auto/Off lever

is in the "OFF" position.

NOTE: Pull coupler back until it clicks

to prevent air from escaping through

the quick connect.

2. Plug the power cord into the

correct branch circuit receptacle.

(Refer to Voltage and Circuit

Protection paragraph in the

Installation section of this

manual.)

3. Open the drain valve fully

(counter-clockwise) to permit

air to escape and prevent air

pressure build up in the air tank

during the break-in period.

NOTE: Always drain tank on a

washable surface or in a suitable

container to prevent damaging or

staining surfaces.

4. Move the On/Auto/Off lever

to "ON/AUTO" position. The

compressor will start.

5. Run the compressor for 15

minutes. Make sure the drain

valve is open and there is

minimal air pressure build-up in

tank.

6. After 15 minutes, close the

drain valve (clockwise). The

air receiver will fill to "cut-out"

pressure and the motor will stop.

will stop.

The compressor is now ready for use.

HOW TO STOP

1. Set the On/Auto/Off lever to

"OFF".

HOW TO START

1. Turn the On/Auto/Off lever to

"AUTO" and allow tank pressure

to build. Motor will stop when

tank pressure reaches "cut-out"

pressure.

2. Turn regulator knob clockwise to

increase pressure and stop when

desired pressure is reached.

NOTE: Always operate the air

compressor in well-ventilated areas

free of gasoline or other combustible

vapors. If the compressor is being

used to operate a sprayer DO NOT

place near the spray area.

BEFORE EACH START-UP

1. Place On/Auto/Off lever to "OFF".

2. Turn the regulator knob

counterclockwise to set the outlet

pressure to zero.

3. Attach hose and accessories.

NOTE: The hose or accessory

will require a quick connect plug

if the air outlet is equipped with a

quick connect socket.

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.
