Grounding

o reduce the risk of static sparking, ground the pump,

object being sprayed, and all other spray/dispensing

equipment used or located in the spray/dispensing

area. Check you local electrical code for detailed

grounding instructions for your area and type of equip

ment. Be sure to ground all of this spray/dispensing

equipment:

Pump

: loosen the grounding lug locknut (W) and

washer (X). Insert one end of a 1.5 mm

2(12 ga)

minimum ground wire (Y) into the slot in lug (Z)

and tighten the locknut securely

. See Fig. 1.

Connect the other end of the wire to a true earth

ground. Order Part No. 237–569, Ground Wire and

Clamp.

Air compressor: follow manufacturer

’

s recommen

dations.

Air and fluid hoses: use only grounded hoses with

a maximum of 500 ft (150 m) combined hose

length to ensure grounding continuity

Spray gun: grounding is obtained through connec

tion to a properly grounded fluid hose and pump.

Object being sprayed: according to your local

code.

Fluid supply container: according to your local

code.

All solvent pails used when flushing, according to

local code. Use only metal pails, which are con

ductive, placed on a grounded surface. Do not

place the pail on a nonconductive surface, such as

paper or cardboard, which interrupts the grounding

continuity.

8. T

o maintain grounding continuity when flushing or

relieving pressure, always hold a metal part of the

spray gun firmly to the side of a grounded metal

pail, then trigger the spray gun.

All Models (See Fig 2)

NOT install the spray tip in the gun yet.

Install an air line filter (H) in the main air line, to re

move harmful dirt and moisture from the compressed

air supply

. Install a bleed–type master air valve (J)

close to the pump air inlet, and downstream from the

pump air regulator (K). Install a second bleed valve (L)

upstream from all other accessories, to isolate the

accessories for servicing.Connect an air supply hose

between the main air supply line and the sprayer

’

s air

inlet swivel (1).

CAUTION

o avoid contaminating the air supply to the gun, do

not use an automatic air line lubricator; lubricate the

motor manually

, instead. See

OPERATION

on page

11.

WARNING

The bleed-type master air valve (J), air relief valve

(9), and fluid drain valve (E) are required in your

system, to help reduce the risk of serious injury

including fluid injection, splashing in the eyes or on

the skin, overpressurization, or injury from moving

parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped

between this valve and the pump. T

rapped air can

cause the pump to cycle unexpectedly

The air relief valve (supplied) opens automatically

to relieve air pressure to the pump if the pressure

exceeds a preset level. This valve prevents over-

pressurization of the spray gun.

The fluid drain valve assists in relieving fluid pres

sure in the displacement pump, hose, and gun;

triggering the gun to relieve pressure may not be

sufficient.
