OPERATION USING PUMP PROTECTOR See Figure 13. Regular use of a commercially available pump protector prolongs the life of the pressure washer by removing hard water mineral deposits, lubricating pump seals and pistons, and preventing freeze damage. Pump protector should be added to the unit after every use and before storage. Pump protector can be purchased at the retailer where you purchased your pressure washer, or by calling customer service. The instructions that follow are typical for adding pump protector but you should always verify the specific instructions provided by the manufacturer of the pump protector used. n Turn off the pressure washer motor, disconnect the power supply, and shut off the water supply. Pull trigger to release water pressure. n Disconnect garden hose and high pressure hose. n Unscrew threaded top from pump protector bottle and remove paper seal from bottle. Reinstall top on bottle and tighten securely. NOTE: The rubber seal should remain inside the threaded top. If it comes out, be sure to replace before reinstalling the top. n Remove bottle cap and attach threaded end of bottle securely to pressure washer pump water intake. n Squeeze bottle to inject contents into pump. n Pump is protected when the protector fluid exits the pump outlet. MOVING THE PRESSURE W­ ASHER n Turn the pressure washer off. Point nozzle in a safe direction and pull trigger to release water pressure. n Disconnect pressure washer from power supply. n Using the carrying handle, get a firm grasp of the unit. Lift the unit into a safe and comfortable carrying position. Move machine to the desired location. MAINTENANCE WARNING: When servicing, use only identical replacement parts.
