7. Rinse out garden hose to flush out debris. PRESSURE WASHER MAINTENANCE Check and Clean Inlet Screen Examine the screen on the 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 Chemical Injection Hose Examine the filter on the detergent tube and clean if clogged.The tube should fit tightly on the barbed fitting. Examine the tube for leaks or tears. Replace the filter or tube if either is damaged. Check Gun and Adjustable 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. Purge Pump of Air and Contaminants To remove air from the pump, follow these steps: 1. Set up pressure washer as described in “Preparing Pressure Washer For Use”. Connect water supply and turn water on. 11 2600 PSI Pressure Washer 12 2. Squeeze trigger on spray gun and hold. 3. When water supply is steady and constant, engage safety latch. To remove contaminants from the pump, follow these steps: 1. Set up pressure washer as described in “Preparing Pressure Washer For Use”. Connect water supply and turn water on. 2. Remove nozzle extension from spray gun. 3. Start engine according to instructions in “How To Use Your Pressure Washer”. 4. Squeeze trigger on spray gun and hold. 5. When water supply is steady and constant, engage safety latch and refasten nozzle extension. Check In-Line Filter Refer to Figure 13 and service the in-line filter if it becomes clogged, as follows: 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. 2. If screen is damaged, the maintenance kit contains a replacement in-line filter screen and an o-ring. If undamaged, reuse screen. 3. Place in-line filter screen into threaded end of nozzle extension. Direction does not matter. Push the screen in with eraser end of pencil until it rests flat at bottom of opening.Take care to not bend screen. 4. Place o-ring into threaded end of extension. Push o-ring snugly against in-line filter screen. 5. Assemble nozzle extension to spray gun, as described earlier in this manual. 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 an orifice clogged or restricted with foreign materials, such as dirt, etc.To correct the problem, immediately clean the orifice using the tools included with your pressure washer and follow these instructions: 1. Shut off engine and turn off water supply. 2. Detach nozzle extension from spray gun.Twist nozzle clockwise to stream position. Using supplied 2mm (5/64) allen wrench, remove orifice from end of nozzle extension (Figure 14). 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 orifice (Figure 14). 5. Using a garden hose, remove additional debris by back flushing water through nozzle extension (Figure 15). Back flush between 30 to 60 seconds.Turn adjustable nozzle extension to stream spray and move nozzle from low to high while flushing. 6. Reinstall orifice and in-line filter into nozzle extension. DO NOT overtighten orifice with allen wrench. 7. Reconnect nozzle extension to spray gun.

Reconnect water supply, turn on water, and start engine. 9. Test pressure washer by operating with nozzle in high and low positions. O–Ring Maintenance O-Rings keep the connections of the hoses and spray gun tight and leak–free.Through normal operation of the pressure washer, they may become worn or damaged. An O–Ring Maintenance Kit is provided with the pressure washer which includes replacement o-rings, rubber washer and water inlet filter. Refer to the instruction sheet provided in the kit to service the 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 sm...
