• Unscrew the drain plug (Ref. 1, Fig. 23).

The oil level should be 55 mm below the filler cap.

Check the oil level every day using the dipstick (Fig. 25).
NOTE: When using hydraulic implements taking a large
quantity of oil out of the transmission (hydraulic
motors, large capacity cylinders) top up oil to the max-
imum level. When you change transmission oil, you
MUST bleed the hydraulic and braking circuits. If nec-
essary, ask your nearest dealer for assistance.

micron steering suction strainer (2. Fig. 27) and the 300
micron LS pump suction strainer (1. Fig. 27)
.
NOTE: the tank must be disassembled for this latter
operation (see your dealer or agent).
