machine and unscrew the four star handles (9-
3/1).
Remove the filter cover (9-3/2).
Remove the filter cartridge (9-4/1) and clean.
NOTICE
The filter cartridge may be cleaned with
water.
ATTENTION
Do not spray filter cartridge with the high-
pressure washer. Insert the filter cartridge
only when dry.

cleaned semi-annually.
