Setup Setup Shipping Damage Connect to Water Supply Check pressure washer for shipping damage. Notify the carrier immediately if there is any damage. Connect hose from water supply to the garden hose inlet on the pressure washer. Connecting High-Pressure Hose and Gun • Connect high-pressure hose between pump outlet and gun inlet. Both of these connections are made with quick couplers. • The supply hose should not be longer than 50 ft (15 m) in length.
Operation Operation Pressure Relief Procedure 4. Turn off water supply and disconnect pressure washer from water. Follow this procedure when you stop spraying and before cleaning, checking, servicing or transporting equipment. ti5425a 1. Engage trigger lock. 5. Unlock trigger lock. Trigger gun to relieve pressure. Engage trigger lock. TI A 2. Turn pressure washer OFF.
Operation Startup • Always engage the gun trigger safety latch when you stop spraying. This reduces the risk of fluid injection or splashing in eyes or on skin if the gun is bumped or triggered accidentally. Be sure latch is pushed fully down or it will not prevent the gun from being triggered. 3. Check oil level in pump. It should be half way up the sight glass, located on the front of the pump. Add pump oil as necessary. The system is equipped with a thermal overload to help prevent severe damage.
Operation 7. Move switch to ON position and set throttle to HALF throttle position. • • OFF ON • ti5434a • • • • CAUTION Do not allow pressure washer to idle for more than 10 minutes. This causes the recirculating water to overheat and can seriously damage the pump. Turn off pressure washer if it will not be spraying at least every 10 minutes. If heated inlet water is used, reduce this time more. Do not operate pressure washer with inlet water screen removed.
Operation 3. Install black (large orifice) chemical tip (Installing and Changing Spray Tips, page 9). The large orifice of the chemical tip causes a drop in pressure that actuates the chemical injector. Changing back to a small orifice spray tip, deactivates the chemical injector and produces high pressure for rinsing. The chemical filter can be left in the chemical container during high pressure spraying. To regulate the flow rate of the chemical, turn the chemical adjustment knob on the injector.
Shutdown, Flushing and Storage Shutdown, Flushing and Storage Short-term Storage (less than 30 days) Long-term (more than 30 days)/Winter Storage • • Do not store unit outside where it can be exposed to rain, dirt or adverse weather conditions. • Do not expose pressure washer to freezing temperatures or allow water to freeze in pressure washer components which could cause the pump to lock-up. If this happens, allow the pump to thaw naturally in a WARM ENVIRONMENT.
Maintenance Chart Maintenance Chart Follow Pressure Relief Procedure, page 6. Interval Daily What to do • Clean water inlet screen and filter. • Check engine and pump oil levels.
