CAUTION

o avoid damaging the pressure control, which may result in poor equipment performance and compo nent damage:

Always use grounded, flexible spray hose (85) at least 50 ft (15 m) long.

Never use a wire braid hose as it is too rigid to act as a pulsation dampener

Never install any shutof (15) and the main hose. See Fig. 1.

a 3/16 in. ID, 3 ft (0.9 m) hose (86) between the main hose and the gun (87). Don’t use thread sealant, and don’t install the spray tip yet!

2. Fill the packing nut/wet-cup (221) Throat Seal Liquid (TSL), supplied.

Check the electrical service.

Electrical requirements: 120 V 15A (minimum).
