WA RNlNG HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand.all instruction manuals before operating equipment.
' 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- -. ~~~
tions have your doctor call the NATIONAL POISON CENTER NETWORK

USE EXTREME CARE WHEN CLEANING TIPS AND SERVICING.
Always follow this pressure relief procedure when shutting off the unit for any reason: shut off the engine. trigger the spray gun. engage fhe trigger EafeQ, close the en ine fuel cock and 0 en the drain VE~VE.
SPRAY GUN SAFETY
When spray gun or dispensing valve is not ECtUaib spraying. ahays set the gun safeQ latch in the Closed or "SAFE position, making the trigger inoperative.
00 NOT REMOVE OR MODIFY any part of the gun.
Check diffuser operation by using the lowest Pmible spray pressure with spray tip removed. Trigger gun end maintain firm metal to metal contact belwean aun and metal waste container. Fluid emitted should be diffused into a i irregular streern
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- mum working pressure rating of at least 4500 pai (310 barl. which is the maximum working pressure of the GH 723. NEVER alter or modify the equipment.
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
Always be sure all equipment end objects being sprayed are Properly grounded. This unit is equipped with a grounding wire end clamp. The
fire or explosion. high Velocity flow of fluid creates static electricity. Sparks may cause
Useonly conductiveor grounded fluid hoses. Be sure gun is grounded through hose connections. Check ground continuity in hose end equipment once e week. Overall (end to end) resistance of un- pressurized hose must not exceed 29 megohms for any coupled length or Combination of hose lengths.
When flushing equipment, remove spray tip, use the lowest possible pressure, end maintain firm metal to metal contact between gun and metal waste container. This reduces the chance of static sparking.
GAS ENGINE PRECAUTIONS
ALWAYS locate unit et least 20 feet awayfrom spraying area because of possible sparking hazard from gasoline engine.
NEVER fill fuel tank while engine is running or hot. Avoid the possibil- ky of spilled fuel causing a fire. Always refuel slowly to avoid spillage.
NEVER operate engine in e closed building unless the exhaust is piped outside. The exhaust contains carbon monoxide, a poisonous,

pull the rope firmly and rapidly to start the engine. If the engine does not start after one or two attempts, try opening the choke a little further. If the engine floods, open the choke all the way and continue pulling the rope.
After the engine has warmed 'up, gradually open the choke lever (GI and close the bypass valve (78). See Fig 3 and 4. Raise the foot brace and engage the hitch (34).
In cold weather, run the engine for about 15 minutes before starting the material pump. This helps to make sure the hydraulic motor does not stall.
Stopping the Engine Open the bypass valve (78) and depress the stop button (J), holding the button down until the engine stops. Close the fuel cock (E). See Fig 3.
Flush the Material Pump Your new unit was tested in oil and the oil was left in to protect the material pump parts. Before using the sprayer, flush the pump as instructed below.
1. Pour enough clean, compatible solvent to fill the system into a large empty metal pail.
2. Place the suction tube into the pail, or tilt the unit back (it will support itself), place the pail under the pump, then tilt the unit forward to lower the pump into the pail.
Lower the foot brace by disengaging it from the hitch (34). Refer to Fig 3. 3. Be sure the bypass valve (78) and fuel cock (E) are

or completely. 4. Close the bypass valve (78). Point the gun into a metal waste container, holding a metal part of the gun firmly against the metal pail. See Fig 5. Squeeze the trigger. At the same time, slowly turn the pressure control knob (F) clockwise just enough to operate the pump. Always use the lowest possi- ble pressure when flushing the unit. Operate the pump until clean solvent comes from the gun. Then release the trigger and engage the trigger safety.

Prepare the Material end Prime the Pump Prepare your material according to the manufacturer's instructions.
Place the displacement pump or the suction tube into the material supply container. Install a spray tip in the gun (see the gun instru,ct#on manual), and start the engine. Trigger the gun Into a metal waste container, holding a metal part.of the gun firmly against the metal container. Refer to Fig 5. Hold the gun trigger open until all air is forced out of the system. Release the trigger, engage the trigger safety, and let the pump stall.
NOTE: The GH 733 can be tilted backwards and will support itself while placing a 5 gallon pail under the material pump.

pattern. The tip size and angle determines the panern width and flow rate. Don't try to get more coverage by increasing the pressure; use a larger tip instead. See the separate instruction manual 306-997 for the correct method'of airless spraying. -H -
:leaning a Clogged Tip
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.

Remove and clean the gun tip at least twice a day when spraying. Always stop the pump at the bonom of its stroke when you are through spraying for the day.
periodically and tighten it if necessary. Refer to Fig 9. Check the tightness of the wet-cuplpacking nut (106)
page 10. The nut should be tight enough to stop leakage, but no tighter. Always relieve the system pressure according to the Pressure Relief Procedure (see above) before adjusting the packing nut.
Check the hydraulic oil level occasionally. Unscrew the cap of the intake filter (9); there should be 1 in. (25 mm) of oil visible in the bottom of the filter screen. Refer to Fig 7, page 7. Use Graco-approved oil only. See AC- CESSORIES.

Periodically,. or if the engine is overheating, follow the Pressure Relief Procedure Warning on page 6. Clean all dirt, dust, etc., off the fan blades, motor and cooler grill. Fig 7
The unit should be level whenever you are checking the hydraulic oil or the engine oil and when replacing or refilling these oils. Refer to the section on "Lubrication" on page 4.
