NOTICE
Chemicals left in the pressure washer can damage the pump and void the warranty. Always rinse the unit thoroughly by running clean water through the chemical hose after using chemicals or cleaning solvents.
To apply chemicals:
1.Push the chemical hose onto the barbed fitting located near the pump water outlet as shown in Figure 8.
Figure 8. The attached chemical hose.
2.Push the other end of the chemical hose onto the chemical hose filter (Figure 9) and fully submerge in a container holding the chemical or cleaning solution.
Figure 9. The attached chemical hose filter.
3.Connect the low pressure chemical nozzle to the spray gun as described on Page 13.
4.After use of chemicals or cleaning solutions, draw clean water through the chemical hose and pressure washer to rinse the internal components.
Standing Water
Source
To draw water from a standing source:
1.Attach the supplied input hose filter to the input hose and place the input hose filter in the standing water source.
Note: Be sure the water source is free from debris which could clog the filter and cause a loss of water flow.
2.Prime the pump by pouring water into the other end of the input hose (the end without the filter) while the filter end is submerged in the water source. Without spilling water out of the hose, connect the input hose to the input port on the pump.
Note: Be sure the water source is large enough to provide 5 GPM of flow for the duration of the pressure washer operation.
NOTICE
If the pump is not able to provide pressurized water when drawing from a standing water source, shutdown the pressure washer immediately and
