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.

7. Automotive type wax may be applied to
all painted and chrome plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may mar the
paint or protective finish.
When finished, start the engine and let it
idle for several minutes.
WARNING

Wet brakes may have reduced stopping abili-
ty, increasing the chance of an accident. Test
the brakes after washing. Apply the brakes
several times at slow speeds to let friction dry
out the linings.
