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.

4. About the thermal protector

The thermal protector operates to stop the motor when a problem such as a motor overload, etc., occurs. If the motor should stop during operation, proceed as follows.

(1)Push the pressure switch knob to the "OFF" position and disconnect the plug from the receptacle (Fig. 2).

(2)If the extension cord does not conform to the specifications given on page 7 replace with an extension cord such as that shown on page 7. If the capacity of the power supply is insufficient, increase the power supply capacity to remove the cause of a flow of excessive current (over-current).

(3)Wait approximately 5 minutes, then press the reset switch of the thermal protector (Fig. 8).

(4)Start up. If the motor still stops during operation, please contact the service center.
