6 - WORKING OPERATIONS
Raise the loader high enough to clear any obstruction
prior to dumping the load.
After the bucket is dumped, back away while lowering and
leveling the bucket, using the return-to-dig feature if re-
quired.
During hard surface operation, place the loader attach-
ment lever in “float” position and keep the bucket level.
This will permit the bucket to “float” on the contour of the
working surface.
If hydraulic down pressure is exerted, the bucket will wear
faster than normal.
The “float” position will prevent the mixing of surface ma-
terial with stockpile material.
It will also reduce the chance of surface gouging when
removing snow or other material.
When loading from a bank select the highest forward gear
which will provide the most efficient loading operation
without going into a “stall”.
Keep the working area free of ruts and holes occasionally
back grading with the bucket using the low rear edge of
the bucket.

For site stripping peeling or scraping, use down pressure
with the loader attachment lever in the lowered position,
and a slight bucket angle to start the cut. Begin the cut at
the notch approximately
50 m
(
1.96 in
) deep and hold the
depth by feathering the bucket to adjust the cutting lip up
or down as required.
When the machine front tires enter the cut, adjust the lift
arms to maintain the correct depth.
Make additional cuts until the desired depth is reached.
Back grade the working area occasionally with the bucket
flat and slight down pressure to keep the working area
smooth and free from ruts or holes.
If the loader attachment lever is moved for lift cylinder ac-
tion without controlling the bucket angle, the bucket may
gouge and leave a series of ruts in the surface.
