GENERAL MAINTENANCE RECOMMENDATIONS The pressure washer warranty does not cover items that have been subjected to operator abuse or negligence.To receive full value from the warranty, the operator must maintain the pressure washer as instructed in this manual. NOTE: Should you have questions about replacing components on your pressure washer, please call 1-800-743-4115 for assistance. • Some adjustments will need to be made periodically to properly maintain your pressure washer. • All maintenance in this manual and the engine operator’s manual should be made at least once each season. Before Each Use • Check engine oil level. • Check water inlet screen for damage. • Check in-line filter for damage. • Check high pressure hose for leaks. • Check chemical tanks and filters for damage. • Check spray gun and nozzle extension for leaks. • Rinse out garden hose to flush out debris before connecting to pressure washer. PRESSURE WASHER MAINTENANCE Check and Clean Inlet Screen Examine the screen on the pumps water inlet. Clean it if the screen is clogged or replace it if screen is damaged. Check High Pressure Hose The high pressure hose can develop leaks from wear, kinking, or abuse. Inspect the hose each time before using it. Check for cuts, leaks, abrasions or bulging of cover, damage or movement of couplings. If any of these conditions exist, replace the hose immediately. WARNING The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation. • NEVER repair high pressure hose. Replace it. • Replacement hose rating MUST exceed maximum pressure rating of unit. Check Gun and Nozzle Extension Examine the hose connection to the spray gun and make sure it is secure.Test the trigger by pressing it and making sure it “springs back” into place when you release it. Put the safety latch in the ON position and test the trigger.You should not be able to press the trigger. Check In-Line Filter Refer to Figure 21 and service the in-line filter if it becomes clogged, as follows: Nozzle Extension Filter Screen O-ring Figure 21 — Clean In-Line Filter 1. Detach spray gun and nozzle extension from high pressure hose. Detach nozzle extension from spray gun and remove o-ring and screen from nozzle extension. Flush screen, spray gun, and nozzle extension with clean water to clear debris. 15 Section 5: Maintenance 2. If screen is damaged, o-ring kit contains a replacement in-line filter screen and o-ring. If undamaged, reuse screen. 3. Place in-line filter screen into threaded end of nozzle extension. Direction does not matter. Push screen in with eraser end of pencil until screen rests flat at bottom of opening.Take care to not bend screen. 4. Place o-ring into recess. Push o-ring snugly against in-line filter screen. 5. Assemble nozzle extension to spray gun. Nozzle Maintenance A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive pump pressure.The principal cause of excessive pump pressure is a nozzle clogged or restricted with foreign materials, such as dirt, etc.To correct the problem,immediately clean the nozzle using the tools included with your pressure washer and follow these instructions: 1. Shut off engine and turn off water supply. 2. Remove nozzle from end of nozzle extension. 3. Remove in-line filter from other end of nozzle extension. 4. Use wire included in kit (or a small paper clip) to free any foreign material clogging or restricting nozzle (Figure 22). Use wire here to remove debris. Figure 22 — Nozzle Maintenance 5. Using a garden hose, remove additional debris by back flushing water through nozzle extension (Figure 23). Back flush between 30 to 60 seconds. Figure 23 — Backflushing the Nozzle Extension 6. Reinstall nozzle and in-line filter into nozzle extension. 7. Reconnect nozzle extension to spray gun. 8. Reconnect water supply, turn on water, and start engine. 9. Test pressure washer by operating with each quick connect nozzle. O–Ring Maintenance Through the normal operation of your pressure washer, o–rings, which keep the connections of the hoses and spray gun tight and leak–free, may become worn or damaged. Provided with your pressure washer is an O–Ring Maintenance Kit which includes replacement o-rings, rubber washer and water inlet filter. Refer to the instruction sheet provided in the kit to service your unit’s o-rings. Note that not all of the parts in the kit will be used on your unit. To remove a worn or damaged o–ring; use a small flathead screwdriver to get underneath the o-ring and pry it off. WARNING The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation. • NEVER repair leaking connections with sealant of any kind. Replace o-ring or seal. Pump Maintenance This model does not require any pump maintenance.The pump i...
