CHECKING COOLANT LEVEL
The coolant level can be checked in expansion tank (1) with the engine
cold, coolant must be between the MIN. and MAX. lower marks.
The check must be performed through the hole positioned on the right
side of the engine hood and the coolant level must be above the MIN.
lower mark.
If the level is near the lower limit of the MIN. mark, fill the tank with
coolant, and if the level decreases considerably and constantly, check
the radiator, engine, and radiator body for leaks. Also check fluid level
in the radiator. See “CHECKING COOLANT LEVEL” on page 3-27.
Expansion tank (1) can be reached after opening the engine hood.
CHECKING ENGINE OIL LEVEL
Dipstick (1) can be reached through opening in the right side of engine
hood, which is protected by inspection cover (2).
The check must be performed with cold engine and the machine located
on level ground.
Oil level can be checked on the graduated dipstick (1) and must be
between MIN. and MAX. marks. If the level is near the MIN. mark, top
off with oil suitable for the ambient temperature, as prescribed in the
lubricant chart. See “FUEL, COOLANT, AND LUBRICANTS” on
page 3-7.
• Do not remove the radiator cap; the coolant must be
checked with the engine cold, through the expansion
tank.
• The upper MIN. and MAX. marks indicate the expansion
level of the coolant at operating temperature.
• After the machine is stopped, the engine is very hot.
• Let the engine cool down before performing any check.
• Hot engines may cause burns.
• If it is necessary to check the oil level during or soon
after work, stop engine and wait for 15 minutes before
checking.
