CAUTION:
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high pressure detergent
applications such as those available in coin-
operated car washers.
4. Once the majority of the dirt has been
hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the machine off immediately with
clean water and dry all surfaces with a
chamois, clean towel or soft absorbent
cloth.
6. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.
