Do not use high-pressure water or
steam to clean the engine or drive
compartment. Water and cleaning
detergent may damage electrical
components and terminals, pos-
sibly leading to component and
safety circuit failure.
In very dirty conditions, debris can build up in
the radiator ns, which blocks air ow. This
can cause the engine to run hot. To clean
out, use a vacuum cleaner or air blower to
remove foreign material from the engine and
drive compartment. Following air cleanout,
use the Radiator Cleaning Wand (PN 609015
available from your Grasshopper dealer) with
water from a normal pressure garden hose to
comb water pressure between radiator ns to
dislodge residual packed-in dust and debris.
Ensure spray angle is straight into the radia-
tor ns and movement is side-to-side from top
to bottom. DO NOT USE HIGH PRESSURE
SPRAY. High pressure, directed at an angle
to the ns, will bend ns, preventing air from
owing through the radiator.
BATTERY MAINTENANCE
Follow the procedure below for battery main-
tenance.
Clean battery.
Inspect cables for loose connection.
Clean terminals.
Inspect battery tray and hold-down.
Inspect battery case for cracks or leaks.
Batteries contain sulfuric acid.

ly explosive hydrogen gas while
being charged. Always keep ciga-
rettes, sparks, open ame and other
sources of ignition away from bat-
tery. Always shield eyes and face
from battery. In the event of ac-
cident, ush with water and call a
physician immediately. Keep bat-
teries and acid out of the reach of
children.
