Pull, ok Fig. 6 Push, no

CAUTION: Do not use the handle (B) to lift and carry unit.

Do not push unit by handle (B). Only use handle (B) to pull unit.

OPERATION

1.Start up

(1)Open the drain cock located at the lower part of the tank (Refer to Fig. 8).

(2)Insert the plug into the receptacle.

(3)Start the compressor by pulling the knob of the pressure switch to “ON” (Refer to Fig. 1 and Fig. 2).

(4)Close the drain cock.

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 with manual reset (push-button), which stops the compressor when the temperature is too high. Should this be tripped, the compressor will restart only if reset is done.

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 (B) is provided to know when the required pressure is reached, lock the knob by pushing it down firmly (Refer to Fig. 7).

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.
