PRE-OPERATION CHECK

TEST OPERATION

To avoid serious personal injury:

A

Keep engine speed at low idle during the test
operation.

A

Escaping hydraulic fluid under pressure can
have sufficient force to penetrate skin, causing
serious personal injury.
Before disconnecting lines, be sure to relieve
all pressure by moving the controls.
Before applying pressure to the system, be
sure all connections are tight and that lines,
tubes and hoses are not damaged.
Fluid escaping from a very small hole can be
almost invisible. Use a piece of cardboard or
wood, rather than your hands to search for
suspected leaks.
If injured by escaping fluid, see a doctor at
once. Serious infection or allergic reaction will
develop if proper medical treatment is not
administered immediately.

A

When the lever is at each corner position marked by
asterisk (*) or lower left, boom and bucket cylinders
work at the same time. However, the lower left position
(Raise & Roll back) is not recommended for scooping
because of insufficient lift force.

To begin a test operation, slightly move the control lever
from the "N" position. Slowly raise the loader boom just
enough for the bucket to clear the ground when fully
dumped. Slowly work through the dump and roll back
cycles.

A

If the boom or bucket does not work in the directions
indicated on the label, lower the bucket to the ground,
stop the engine, and relieve all hydraulic pressure.
Recheck and correct all hydraulic connections and oil
level.

REMOVING AIR FROM THE HYDRAULIC

SYSTEM

Repeat raising and lowering the boom and bucket
operations until all the air is removed from the system and
the system responds properly.

A

Do not move the control lever into the float position
when the bucket is off the ground.
