MAINTENANCE
EVERY 1000 HOURS
CLEANING THE ENGINE COOLING
SYSTEM
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine, muffler, radiator and many
other parts of the machine are hot
immediately after the engine is
stopped. Touching these parts will
cause burns.
· The engine coolant is also hot and
under high pressure immediately after
the engine is stopped. Be careful when
loosening the caps or plugs. Working
on the machine under these conditions
could result in burns or injuries due to
the hot coolant spurting out.
• If maintenance must be performed with
the engine running, always work as a two
person team communicating each other.
· One person must sit in the operator’s
seat so that he/she can immediately
stop the engine when necessary. He/
she must take care not to touch the
lever or pedal unless necessary.
· The one who performs maintenance
must make sure to keep his/her body
or clothing away from the moving part
of the machine.
• Standing at the back of the machine
while the engine is running is extremely
dangerous, as the machine could move
suddenly. Never stand at the back of the
machine while the engine is running.
• Do not remove the radiator cap or the
drain plug when the cooling water is
hot. Stop the engine and wait until the
engine and the cooling water cool.
Then, slowly loosen the radiator cap
and the drain plug to remove them.
• Be sure to secure the rear door or
radiator before working the inside.
EVERY 1000 HOURS
Note: When cleaning, if the temperature of
the coolant is low, the thermostat will be
closed and the coolant will not circulate in
the radiator. Heat the coolant water to at
least 90°C (194°F) before cleaning.
1. Open the rear door and remove the under
cover (5).
2. Gradually loosen the radiator cap (3) to
release the internal pressure, and then
remove the cap.
3. Place a pan for catching the waste coolant
under the drain plug (4), and then loosen
the drain plug (4) to drain the coolant.
4. Tighten the drain plug (4).
5. Add tap water to the radiator through the
coolant fill port up to the top of the port.
Take time and slowly add water, so that no
air enters the radiator.
6. Close the radiator cap (3).
7. Start the engine and run it at a speed
slightly above low idling. Raise the water
temperature to at least 90°C (194°F), and
then run the engine for about 10 minutes
with the thermostat open.
