While your pressure washer has been produced
with quality materials and craftsmanship, you as the
owner have certain responsibilities for the correct
care of the equipment. Attention to regular
preventative maintenance procedures will assist in
preserving the performance of your equipment.
Contact your Hydro Tek dealer for maintenance. A
small investment in preventative maintenance will
add many hours to the life of your pressure washer.
Perform maintenance more often under severe
conditions. Do not spray high-pressure water onto
the machine.
Not all maintenance items apply to
all machines.
