Preventive Maintenance
This pressure washer was produced with the best available materials and quality craftsmanship. However, you as
the owner have certain responsibilities for the correct care of the equipment. Attention to regular preventative main-
tenance procedures will assist in preserving the performance of your equipment. Contact your dealer for mainte-
nance. Regular preventative maintenance will add many hours to the life of your pressure washer. Perform
maintenance more often under severe conditions.
Check pump oil level before first use of your new pressure washer. Change pump oil after first 50 hours and
every year or 500 hours thereafter. Use SAE 10W-40 weight oil, non-foaming.
Refer to the engine's operating manual included with machine for recommended engine oil.
