'

INJECTION HAZARD

Fluids under high pressure from spray

or

leaks

can

penetrate the skin and cause extremely serious injury, Including the need for amputation.

NEVER

point the spray gun et anyone

or

any part

of

the body

NEVER

put hand or fingers over the spray tip.

NEVER

try to stop

or

deflect leaks with your hand or body

ALWAYS

have the tip guard in place when spraying.

MEDICAL TREATMENT

If

any fluid appears to penetrate your skin, get

EMERGENCY MEDICAL CARE AT ONCE.

DO

NOT TREAT AS A SIMPLE CUT.

Tell the doctor exactly what fluid was iniected. For treatment instruc-

CHECK OPERATION OF ALL GUN SAFETY DEVICES BEFORE EACH USE.

AVOID COMPONENT RUPTURE

Always be sure that all components used with this unit have e max-

Before each use, check hoses for weak, worn or damaged conditions that may be caused by traffic, sharp corners, pinching, kinking end general wear. Tighten all fluid connections securely before each use.

REPLACEany damaged hose.

NEVER

use tape

or

any device to mend

the hose.

PREVENT STATIC SPARKING

GAS ENGINE PRECAUTIONS

ALWAYS

locate unit et least

Pressure Relief Procedure

WARNING

Always relieve system pressure whenever you are done spraying for a while and before installing, removing or cleaning any parts to avoid possible injury from high pressure fluid in the system.

Always

follow

this procedure: shut

off

the engine

by depressing the stop bunon

(J),

trigger the spray gun, engage the trigger safety, close the engine fuel cock

(E),

and slowly open the dram

valve

(143).

Leave the drain valve open until you

are ready to use the unit again.

Clean out the front of the tip frequently during the day's operation with a solvent soaked brush. This helps to prevent material build up and tip clogging.

If the spray tip clogs while spraying, follow the Pressure Relief Procedure, above. Loosen the tip guard slowly before removing

it

completely. Remove the tip and put

it

and the nozzle of the gun in solvent. Let the tip soak

long enough to dissolve the obstruction, or blow

it

out

with

air

through the front of the'tip. If the

air

and

sol-

vent does not loosen the obstruction, tap the back of the tip against a flat surface to jar

it

out.

Flush the unit

if

the material you are pumping will dry

leave mineral spirits in the pump during storage to help prevent corrosion of material pump.

Whenever

it

is possible, park the unit

in

the shade or in a relatively cool area to reduce the possibility of overheating.

Remove and clean the gun tip

at

least twice a day when

CAUTION

The alignment of the engine mounting flange

(641

to the engine and the alignment of the coupler

(661

which connects the hydraulic

pump

1691 shaft

and the engine shaft are critical. If the coupler has failed, Graco recommends that you contact your

~

nearest factory branch or the Graco Service

Department for detailed service information.

Cooler

Special care must be used if the return tube 1139). the

9oo

elbow

(43)

or the hose

(88)

leading

into

the elbow

are removed from the cooler (47). The return tube and elbow each connects to a hex-shaped male adapter

(K)

which is part of the cooler core assembly.

See

Fig 10.

The adapter is made of aluminum and can be easily

damaged.

So,

whenever

you

are working on these

adapter. Remove and replace the necessary cooler parts

parts, hold a wrench stationary on the hex of the male

as instructed

in

paragraphs 2 and 3 of the Hydraulic

Pump section (column

1

).

Reassemble the cooler in the

elbow, use a liquid sealant on the threads and screw the

reverse order of disassembly. When installing the

elbow~onto the adapter by hand. Tighten the nuts (L). Refer to Fig 10.

Motor

Mounts

If the motor mounts (32) must be replaced, be careful to install them correctly and evenly. The

nut

(30) must be

screwed onto the capscrew (31)

so

the first thread of

the screw is just flush with the top of the nut. Refer to

the Parts Drawing, page 14.
