Lower loader and boom to the ground until front tires are off ground.

Pivot and lock operator seat into position facing to the rear.

Lower stabilizers until rear tires are off ground and machine is level.

Remove swing lock pin and store in holder.

Unlock boom lock.

Check control lever response.

ositioning Spoil Piles

104828

o prevent cave-ins, place spoil pile at least 1m (3 ft) away from edge ofxcavation. Deeper excavations require larger area for spoil pile. Place spoilles in convenient locations for easier truck loading or backfilling.

n slopes, place piles on upper side for improved machine stability and easierackfilling.

eveling Machine


Prevent unexpected machine movement. Stabilizers must be lowered onto aard, level surface. Do not dig under stabilizers. Be alert to possible machine

movement when raising the stabilizers and loader bucket.

Keep both feet on subframe platform and away from stabilizers whenperating attachment.

Do not operate attachment controls from the ground. Operator must be

ositioned on the operator seat.

Position machine on a hard, level surface when operating the backhoe.

Level work area as necessary.

OTE: When stabilizers are lowered to level machine, they may not bextended the same length due to variations in surface.
