CAUTIONB
Never run thecleaning unit dry. Costly damage to thepumpwill result. Always be sure the water supply is completely turned on before operating.
Inspect all connections for any leaks. Tighten if necessary.
Cleaning
For cleaning with harsh chemicals, see the Chemical In- jector Kit manual
For cleaning with clear water, test the distance you will need to hold the spray nozzle from the surface on a scrap piece of similar material. For softsurfaces such as wood, hold the nozzle about 3 ft (1 mm) from thesur- face and gradually bring it closer, checking to see if the high pressure spray is damaging the surface. Always hold the nozzle at an angle to thesurface and "chisel" off the dirt. When you have finished cleaning, shut off the unit and trigger the spray gun to relieve pressure.
WARNING
Follow these precautions when removing and in- stalling nozzles:
1.Shut off the cleaning unit and trigger the gun to relieve pressure. Engage the trigger safety.
2.Keep the nozzle and the tubepointed away from you and everyone else.
3.Do not put your hand over the tip topush the nozzle into place.Grasp it from the side and keep your fingers away from thetip.
14. Do not let anyone else touch the spray valve while you are changing nozzles.
5. Be sure the slip ring is pushed forward to lock the nozzle in place before triggering the spray gun.
Shutdown and Care of Unit
When the unit is not in use, turn off the water supply.
When shuning down forthe day or weekend, shut off the unit, shut off the watersupply valve, and trigger the gun to relieve pressure. Wipe off the unit with a damp rag.
Check the filter screen in the water inlet connection as often asnecessary, at least daily. Do not operate the unit with theinlet and filter screen removed.
DO NOT try to adjust the unloader valve or change the engine speed. Changing these settings may cause ex-
cessivepressure, intermittent unloader operation, wasted fuel and increased wear on parts and will void the warranty.
THE PUMP MUST NOT BE RUN DRY and must be
drained of waterbefore exposure to freezing temperatures. Use and store the unit where it will not be subjected to freezing temperatures. If water does freeze in the unit, thaw before tryingto start. A 50% anti- freeze solution may be pumped prior to cold weather storage.
Use only spray tips thatare matched to the unit to avoid excessive cycling and wear of the unloader valve. See
ACCESSORIES.
pour hot water on a frozen pump. A sudden
I temperature change may crack .the ceramic I plungers.
Do not pump caustic materials.
Before extended storage, flush the pumpwith light oil.
Avoid dragging hose over an abrasive surface such as cement. This causes~excessivewear and shorter hose life.
Clean the intake line strainer daily.
Lubrication and Care
Fill the pump crankcase to the dot theon oil gauge win- dow with 25 oz (0.75 liters) of crankcase oil
NEVER alter adjustment or modify the unloader
Alteringor adjusting unloader wi// not increase' erformance of unit.
