WARNING
FILLING THE BUCKET
Approach and enter the pile with a level bucket. A To avoid serious personal injury:
Do not attempt to lift bucket loads in
excess of the loader capacity.
Before raising the bucket to full height,
make sure the tractor is on level ground.
If not, it may tip over, even if the tractor
is not moving.

To avoid serious personal injury:
Handling large, heavy objects can be
dangerous due to :
(A) Danger of rolling the tractor over.
(8) Danger of upending the tractor.
(C) Danger of the object rolling or
sliding down the loader boom onto

If you must perform the above work,
protect yourself by :
(A) Do not lift the load higher than
necessary to clear the ground when
moving.
(8) Add rear ballast to the tractor to
compensate for the load.
(C) Do not lift large objects with
equipment that does not have an
anti-rollback device.
(D) Move slowly and carefully.
(E) Avoid rough terrain.
