Squeeze trigger to purge air from pump. 6. Insert nozzle. 7. Start engine. Shut-Down Instructions 1. Turn engine OFF. 2. Turn water supply OFF. 3. Squeeze trigger to relieve system pressure. 4. Remove garden hose. 5. Remove pressure hose. 6. Turn fuel valve OFF (if equipped). WARNING Skin puncture hazard.
Operation Instructions Spray Gun Safety Lock When not spraying, use the spray gun safety lock to prevent accidental high pressure discharge. spray gun spray gun safety lock * Note: Depending on model, gun may appear differently. Attaching the Lance Tighten spin-on coupler hand tight. Note: The o-rings make the seal so there is no need to tighten with a wrench.
Operation Instructions To install a nozzle pull back the collar and push the nozzle into the coupler.
