Change oil after the first 50 hours of use. Use a SAE20 or 30 non-detergent oil. After that, change oil every 200 hours, once a year or when it looks milky, more frequently if used in demanding environments.
Changing oil is one of the most important and lease expensive maintenance items, it will prolong the life of your pressure washer.
1. Check water inlet screens for signs of debris.
2. Check nozzle for debris and signs of extensive wear. Worn nozzle will result in poor performance. Only check nozzle with the motor turned “OFF” and the pressure relieved from the system!
3. Check all fittings and connections for leaks and worn areas.
The gun nozzle supplied with the pressure washer provides optimum cleaning for universal cleaning applications if used properly.
Cleaning agents are most effective when the surface is rinsed first to loosen dirt. After pre-rinsing to loosen dirt, then clean with detergent.
Detergent should be applied from the bottom to the top of the washing area. Apply detergent and allow the detergent to react with the dirt, then rinse from the top to the bottom. This detergent applying and rinsing technique will help to avoid streaks and skips in the washing area.
Never use more detergent than is necessary to clean the surface.
Always follow directions supplied by the detergent manufacturer on the container.
For best spraying results, hold the gun 6 – 12” away from the washing surface and use long, slow deliberate side to side strokes, similar to using a paint sprayer. This technique will provide the most effective cleaning impact and minimize streaks and skips in the cleaning process. Waving the spray gun aimlessly across the surface wastes water and expensive detergent and prolongs the cleaning process.
If the pressure washer is used to apply wax, the gun should be held further from the surface to optimize the “misting” effect when applying the wax. For best results, follow the directions supplied by the wax manufacturer.
GUN, WAND AND NOZZLE:
Hold the gun/wand in the normal operating position. Turn the nozzle sleeve clockwise for a fan spray and counterclockwise for a stream. (Pull the nozzle sleeve forward for high pressure while pushing the sleeve away from the gun for low pressure). After shutting down the unit and draining the hose, spray a lubricant, such as WD40, on the backside of the nozzle and work the nozzle back and forth from high to low pressure. This will help prevent the nozzle from sticking. Examine nozzle tip for blockage only with pressure washer “OFF” and pressure relieved from systems.
