STORAGE & MAINTENANCE INSTRUCTIONS
Engine
The engine instructions that accompany your unit detail specific procedures for maintenance of the engine. Fol- lowing the engine manufacturer’s recommendations will extend engine work life.
Pump
The pump oil must be changed after the first 25 hours of operation on all units. Once the initial oil change has been completed, it is recommended the oil be changed every 3 months or 250 hour intervals. If oil appears dirty or milky, changes may be required at a greater frequency. Add pump oil and fill only to the center of the sight glass (Refer to the parts listing for the correct pump oil). Do not overfill.
Nozzles
Water flow through the spray nozzle will erode the ori- fice, making it larger, resulting in a pressure loss. Noz- zles should be replaced whenever pressure is less than 85% of the maximum. The frequency of replacement will depend upon such variables as mineral content in the water and number of hours the nozzle is used.

There is an
Belt Tension Adjustment
To maintain peak performance of your pressure washer, it may be necessary to adjust the belt tension on occa- sion. Follow the procedure outlined below.
1.Remove the belt guard and loosen the two nuts on each side of the pump. (Reference A) There are a total of 4 nuts.
2.Turn the cap screw (Reference B) clockwise until a 1/2 inch belt deflection is noticed between the pulleys.
3.Tighten the side nuts. (Reference A)
4.Put a straight edge across both pulleys. If necessary, loosen one set of pulley screws and adjust in or out to properly align. Tighten the pulley screws and check the tension again.
