1.
Park the machine on a level surface.
2.
Lower the tines to the ground.
3.
Shut off the engine, engage the parking brake,
remove the key, and wait for all moving parts to
stop before leaving the operating position.

Remove the cap and check hydraulic-fluid level
in the reservoir
(Figure
Note:
The hydraulic-fluid level should cover the
word Cold that is embossed into the baffle of
the reservoir.

If necessary, add the specified hydraulic fluid to
the reservoir until the fluid covers the Cold fluid
level on the baffle

level depending upon the temperature of the
fluid. The fluid level varies with the temperature
of the fluid. The Cold level shows the level of
the fluid when it is at 24°C (75°F). The Hot
level shows the level of fluid when it is at 107°C
(225°F).
For example: If the fluid is at ambient-air
temperature, about 24°C (75° F), fill only to the
Cold level. If the fluid is about 65°C (150° F), fill
to halfway between the Hot and Cold levels.

Replace the hydraulic reservoir cap and tighten
it until it is snug
Note:
Do not overtighten the reservoir cap.
