2.Do not alter the ground prong or use an adapter.

3.A 12 AWG, 3-wire, grounded 150 ft extension cord may be used with this equipment.

NOTE: Long extension cords affect sprayer perfor- mance.

How to use the gun safety latch

When engaged, the gun safety latch prevents the gun from accidental triggering. See Fig. 4.

WARNING

If the gun still sprays when the gun safety latch is engaged, adjust the gun. See manual 307614, supplied.

How to use the pressure control

The pressure control controls the motor operation so the sprayer maintains constant fluid pressure at the pump outlet. Turn the pressure control knob fully counterclockwise to obtain the minimum setting. Turn the knob clockwise to increase pressure. See Fig. 6.

How to use the pressure drain valve

Use the pressure drain valve to relieve fluid pressure from the pump and to help prime the pump. If the valve senses an over-pressure condition, it opens automati- cally to relieve fluid pressure. If this happens, stop spraying immediately, shut off and unplug the sprayer. Determine the cause of the problem and correct it before operating the sprayer again. Refer also to the Troubleshooting Guide, page 14. See Fig. 5.
