Check the fluid level daily.

With the platform fully lowered, open the control module and remove the reservoir breather/cap. Fluid
should be at the full mark.

C A U T I O N

The hydraulic fluid may be of sufficient temperature to cause burns. Wear safety gloves and safety
glasses when handling hot fluid.

Clean the breather/cap at
the same time that the
fluid filter is replaced. Use
cleaning solvent and blow
dry with clean dry com-
pressed air.

EPLACEMENT

Figure 2-13:

Fluid Filter

Replace the filter every 250 hours or six
months.

1. Unscrew the filter from the filter assembly.

2. Apply a thin film of clean hydraulic fluid to

the gasket of the replacement filter.

Screw the replacement filter onto the filter
head until the gasket makes contact, then
turn the filter ¾ of a turn further.
