MAINTENANCE 29
IF COOLANT OVERFLOW PERSISTS:
1. Clean dirt and debris from the radiator guard, if equipped,
and the radiator core (fins and tubes) to ensure that cool-
ing air flow is not obstructed.
2. Check and adjust the fan belt (see page 34).
3. If a cooling system blockage is suspected, drain and flush
the cooling system with a suitable radiator cleaner. Refill
with fresh coolant. If a blockage persists, contact your
dealer or professional radiator service.
CHECKING RADIATOR HOSES
1. Inspect radiator hoses every 6 months or 200 operating
hours; whichever comes first.

Check for leaks and repair or replace promptly. Tighten
hose clamps regularly.
! ! ! ! !
Hoses that are cracked, swollen or brittle must be re
placed as failure is eminent. Hose failure will result in
engine overheating and possible injury.
2. Replace cooling system hoses every 2 years. New hose
clamps should always be used when replacing hoses.
IF ENGINE OVERHEATING OCCURS:
1. Never disregard an engine warning light or other alarm.
2. Safely stop the machine. Remove any load from the engine
and reduce the engine speed to idle.
3. If the engine stalls, do not restart. For your safety, stay
away from the engine until it cools.
4. Allow the engine to idle for 5 minutes before shutting it
down.
5. After shutdown, allow the engine to cool before trouble-
shooting and repair. Stay away from an overheated en-
gine until it cools as steam or hot coolant may escape vio-
lently without warning.
6. After the engine cools, consult the “Troubleshooting” sec-
tion of this manual to determine the cause. Make repairs
and adjustments as required.
7. For your safety, never pour coolant or water into a hot
system.
CLEANING THE RADIATOR CORE
Flush the radiator core with fresh water to remove external
dirt and debris. Cleaning should only be done when the system
is cold.
