6 - WORKING OPERATIONS
To backfill a trench efficiently it is necessary to move the
maximum amount of soil without losing speed. If "stall" oc-
curs downshift or reduce the depth of cut. If the machine
is not working at capacity in the gear selected, increase
the depth of cut. Operate at right angles to the trench
with the loader bucket level. Leave the soil in the bucket
as emptying the bucket on each pass is time-consuming,
and leave soil that drifts over the side of the bucket for
the final clean up. One lengthwise cleanup is usually suf-
ficient to gain an acceptable grade after backfilling. When
backfilling from a large pile, shovel the top of the pile by
pushing toward the excavation. Drag some soil rearwards
to form a work ramp of the convenient grade. If during the
backfill operation the machine front wheels get stuck in a

trench dump the bucket and apply down pressure to lift
the front wheels from the trench. Actuate the bucket as
engine power is applied to move the machine rearwards.
NOTE: Maximum bucket down pressure may be obtained
by progressively shifting the loader attachment lever to the
right.
NOTICE: The safe working load of the loader attachment
is calculated using a standard bucket, therefore, when us-
ing another bucket or attachment for lifting or handling a
load, the weight of the bucket or attachment must be taken
into account when calculating the rated load of the loader
attachment. Safe working load = 1000 kg (2205 lb).
