Excavation

Loading Accumulated Soil

IMPORTANT:
 Do not dig or scoop with machine frame articulated.
 Avoid operating the machine with the front wheels
raised off the ground. Machine traction force is
reduced and excessive loads are applied to the
undercarriage.
Scoop load while moving the machine forward as
described below. As load increases the wheels begin to slip,
slightly raise the lift arm to increase tire grip.
f
NOTE: When loading rocks or hard packed material, the use
of bucket teeth is recommended.
1. Move the machine forward to the material.
Steer the machine in a straight ahead position when
entering the material.
2. Lower the bucket parallel to the ground. Drive the
bucket straight into the material.
f
NOTE: Use approximately 1/2 - full engine speed.
3. Raise the lift arm while running the machine forward
slowly in 1st or 2nd speed. Use 2nd speed for loose
materials.
4. Move the bucket control lever to the "Roll Back" and the
"Hold" position several times to get more material in the
bucket.
When the bucket is filled, move the bucket control lever
to the "Roll Back" position.
5. Move the machine with the bucket rolled back fully and
held at the driving position.
f
NOTE: Steer the machine in a straight ahead position when
entering the material. Aim the center of the bucket at the
protruding portion of the material.
