Actuator Oil Level
Under normal conditions, actuator oil level should re-
mainconstant.Ifanyoilisspilledfromthereservoirdur-
ing air bleeding, the oil level in the actuator should be
checked and adjusted.
1. Make sure that the exterior of actuator is thoroughly
clean to prevent contaminates from entering the actua-
tor.
2. Makesurethattheactuatorcylinderisfullyretracted.
IMPORTANT: To prevent actuator damage, use vise
with protective jaws when clamping actuator.
3. Placetheactuatorinavisemakingsurethatactuator
is clamped in the area identified in Figure 66. Use just
enough clamping force to hold the housing securely.
Make sure that the reservoir plug is orientated up.
CAUTION
The actuator reservoir is pressurized. If the res-
ervoir plug is removed too quickly, oil under
pressure can be ejected from the actuator.
4. Slowly loosen and remove the reservoir plug at the
top of the reservoir.
5. Using a light through the plug hole, confirm that the
reservoiroilis clear.Iftheoil appears milky,performac-
tuator air bleeding procedure.

7. Whenoilleveliscorrect,usea12voltDCpowersup-
ply to power the actuator and extend the cylinder com-
pletely.
IMPORTANT: To ensure proper reservoir pressure,
make sure that cylinder is extended before instal-
ling reservoir plug.

Actuator Disposal
If actuator disposal is necessary, remove hydraulic oil
from actuator before disposal.
1. Open actuator reservoir (see Steps 1 through 4 in
Actuator Air Bleeding above).
2. Drain oil from actuator.
