System must be manually relieved to prevent it from starting or spraying accidentally. Fluid under high pressure can be injected into the skin and cause serious injury. To reduce risk of injury from injection, follow this procedure whenever you are instructed to relieve pressure, stop spraying, service equipment or install or clean spray tip. Read warnings, page 4.
1 Set pump valve OFF. Turn engine OFF.
TIA
2Turn pressure to lowest setting. Trigger gun into pail to relieve pressure.
Operation
General Repair Information
•Hydraulic system and engine may become very hot during operation and could burn skin if touched. Flammable materials spilled on hot, bare motor could cause fire or explosion. Have belt guard in place during operation to reduce risk of pinching or loss of fingers.
•Install belt guard before operation of sprayer and replace if damaged. Belt guard reduces risk of pinching and loss of fingers.
To reduce risk of serious injury,:
•Keep all screws, nuts, washers, etc. removed during repair procedures. These parts usually are not pro- vided with replacement kits.
•Test repairs after problems are corrected.
•If sprayer does not operate properly, review repair procedure to verify you did it correctly. See Trouble- shooting, page 7.
•Do not touch moving parts with fingers or tools while testing repair.
3 Open prime valve (vertical).
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 pres- sure gradually, then loosen completely. Then clean tip and hose.
