Cooling System
Important: Check the cooling system daily to prevent overheating, loss of perfor-
mance and engine damage. Drain, flush and refill coolant every year or 1,000
hours.
Checking Coolant Level
1. With the engine at operating tempera-
ture, open the engine cover. Looking
at its plastic coolant recovery tank,
check that the coolant tank fluid is
half way up on the recovery tank,
between full and low markings on the
coolant tank (Figure 48).
2. Allow the coolant to cool. Do not
remove the fill tube cap when the
coolant is hot. Serious burns may
occur.
3. Add premixed coolant, 50% water and
50% ethylene glycol, to the tank if the
coolant level is low.
Cleaning the Cooling System
Allow sufficient time for the oil radiator to
cool before working on or near it. Parts get
extremely hot during operation and can burn you.
The radiator assembly is mounted between the engine and the hinged rear grille.
When operating correctly, air is blown through the openings between the fins by
the engine fan. During operation dust and debris can build up on the engine side
of the radiator and restrict air flow through the fins. To remove this restriction,
use compressed air and direct the flow through the fins from the rear of the radi-
ator toward the engine.
1. Lower the lift arm and stop the engine. Allow the machine to cool.
2. Raise the engine cover and open the rear grille (page 70).
3. As necessary, clean the radiator and air cooler by blowing compressed air
through the fins from the rear, toward the engine.
