Maintenance
flushing out radiator and replacing coolant
„ Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open
the radiator cap while draining. Remove the overflow

radiator cleaning
The radiator (Figure 42) should be sprayed (cleaned) with
a high pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.

BaTTery/charging sysTem
Mishandling of the battery shortens its service life and adds
to maintenance cost.
1. Check and clean battery terminals for corrosion.
2. Check the battery regulatory and make sure that each
electrolyte level is to the bottom of the vent well (Figure
43). If necessary, add only distilled water in a well-
ventilated area. Never operate or recharge without
sufficient fluid in the battery.
Figure 43. Battery Fluid Levels
3. Never attempt to charge a battery that is frozen. The
battery can explode unless first allowed to thaw.
warning

hydrogen gas while charging or during
operation). Keep area around battery well
ventilated and keep from any fire source.

chemical (dilute sulfuric acid). Avoid
contact with eyes and skin. always wear
eye protection and rubber gloves. If your
clothing or skin comes into contact with battery acid,
immediately wash off with running water and get
