HYDRAULICS
5-4 ATLV 4300 330495 (10--98)
HYDRAULIC FLUID RESERVOIR
The reservoir is located on the left side of the
machine next to the engine.
A filler cap is mounted on top of the reservoir. It
has a built in breather and fluid level dipstick.
Replace the cap after every 800 hours of
operation.
Check the hydraulic fluid level at operating
temperature daily. The dipstick is marked with full
and add markings to indicate the level of hydraulic
fluid in the reservoir. Cold fluid level is mid-point of
add and full lines.
Lubricate the filler cap gasket with a film of
hydraulic fluid before putting the cap back on the
reservoir.
ATTENTION! Do not overfill the
hydraulic fluid reservoir or operate the
machine with a low level of hydraulic
fluid in the reservoir. Damage to the
machine hydraulic system may result.
Drain and refill the hydraulic fluid reservoir with
new hydraulic fluid every 800 hours of operation.
NOTE: When the hydraulic filter bypass light
(optional) comes on, replace the filter, and change
the hydraulic fluid as soon as possible.
The hydraulic fluid filter is located in front of the
hydraulic reservoir near the rear of the engine
compartment. Replace the filter element every
800 hours of operation.
