MAINTENANCE
Very little regular maintenance is required, other than general cleaning on the outside of
the machine. Wipe over with a clean dampened soft cloth, use a mild household detergent
if necessary. Never use harmful chemicals.
If detergents have been used in the washer, it is important to flush the system with clean
water for a few minutes after use.
If there is a danger of freezing, anti freeze should be mixed with the flush water, or the
system must be completely drained.
Storage
Store in an upright position, completely drained of water, in a dry frost free location.
Engine
Refer to the engine handbook, and service accordingly.
NOTE: Engine oil should be checked before each use.
Pump
Change the oil after the first 50 hours of service, and every 500 hours thereafter.
