Such use could result in a chemical reaction, with the possibility of explosion. DDo not fill fuel tank while engine is running or hot. DDo not flush with gasoline. Fluid injection and high pressure hazard: High pressure spray or leaks can inject fluid into the body. To help prevent injection, always: DEngage trigger safety latch when not spraying. DKeep clear of nozzle and leaks. DNever spray without a tip guard. DDo PRESSURE RELIEF if you stop spraying or begin servicing sprayer. DDo not use components rated less than sprayer Maximum Working Pressure. DNever allow children to use this unit. If high pressure fluid pierces your skin, the injury might look like “just a cut”, but it is a serious wound! Get immediate medical attention. 309412 3 Maintenance CAUTION WARNING INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D D D D are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray tip. Pressure Relief Procedure 1. Lock gun trigger safety. 2. Turn engine ON/OFF switch to OFF. 3. Move pressure control switch to OFF and turn pressure control knob fully counterclockwise. 4. Unlock trigger safety. Hold metal part of gun firmly to side of grounded metal pail, and trigger gun to relieve pressure. 5. Lock gun trigger safety. 6. Open pressure drain valve. Leave valve open until ready to spray again. If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Now clear tip or hose. 4 309412 For detailed engine maintenance and specifications, refer to separate Honda Engines Owner’s Manual, supplied. DAILY: Check engine oil level and fill as necessary.

This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations. This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non--Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco. This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
