Section 2: Operating Procedures
2/5/19
CB0550 4-in-1 Combination Bucket 381-139M
16
If digging into a pile:
a. Lower loader arms until the bucket is on the
ground.
b. Tilt front of bucket down until cutting edge is on the
ground.
c. Start driving slowly into the pile. As the bucket
begins to fill, slowly raise loader arms until bucket
if filled to rated capacity.
4. With bucket filled, stop and raise bucket. At the same
time, tilt top of bucket back to keep material from
spilling out of the bucket.
5. Make sure bucket and load clears all obstacles when
making a turn or backing away.
6. Position load at a safe, low height and top of bucket
tilted slightly back to transport to the dump site.
Picking Up A Load With The Jaws/Clamshell
1.
Make sure load does not exceed rated lift capacity of
the tractor being used to lift the load.
2. Center tractor on the material to be picked up.
3. Make a complete stop in front of the material and
position bucket at the proper height.
4. Fully open the jaw and drive forward until the bucket
is above the pile. Do not ram bucket into the pile.
5. Lower bucket onto the pile and close the jaw to
secure the load.
6. Lift load a few inches to make sure you have good
control of the load. If load is not secure, release and
recapture load in a more secure location.
7.
Lift load above the pile and then back load out of the
pile slowly making sure load clears all obstacles.
8. Not always will the load be secured properly in the
bucket when pulled free from a pile. Before traveling
with a loose load, lower load to ground, release load,
and re-clamp load to make it more secure.
9. Position load at a safe, low traveling height and begin
transferring to the dump site.
Traveling With A Load
1.
Pedestrians always have the right-of-way.
2. Keep load tilted back slightly.
3. When possible, travel with the load low to the ground.
4. Continually scan all sides for pedestrians, other
traffic, and obstacles.
5. If load is large and blocks your view, travel in reverse.
6. Always drive at a safe speed and slow down when
going around corners. Avoid sudden braking.
7.
Leave enough clearance when turning so that the
bucket and load does not contact obstacles such as
vehicles, buildings, trees, fences, etc.
8. When traveling over a ramp or incline, keep load on
the “uphill” side of tractor.
9. When possible, travel straight up and down grades,
ramps, and inclines. Avoid making turns on grades,
ramps, and inclines.
10. Raise or lower load only when stopped, never when
traveling.
11. Slow down when traveling over rough or hilly terrain.
12. Do not transport loads on public roadways.
13. Transport on public roadways without a load and
transport in such a way that faster moving vehicles
may pass you safely.
14. Plan your route to avoid heavy traffic.
Releasing A Load
1.
Stop in front of desired location and slowly raise load
to the required height for dumping.
2. Move slowly forward while checking to make sure
bucket and load clears all obstacles.
3. Stop forward movement when load is positioned over
its release location.
4. Releasing the load requires a combination of tilting
the front of bucket down or opening the jaw, and
raising the loader arms. The order in which the load
is released will vary depending on type of material
being released. The most important objective is to
have the load under control throughout the release.
5. Once the load has settled onto the pile, tilt bucket
level and close the jaw if opened.
6. Slowly back up making sure the bucket clears all
objects and no pedestrians or other traffic are behind
or on either side of tractor.
7.
As you back away, leave enough clearance when
turning and/or lowering the bucket so that it does not
make contact with obstacles such as vehicles,
buildings, trees, fences, etc.
8. When clear of the pile, stop and lower bucket to
transporting height (low to the ground) before moving
again.
Scraping, Leveling, & Digging With The Jaw
1.
Make a complete stop in the area to work and fully
open the jaw.
2. Rotate top of hitch plate forward and lower loader
arms down until cutting edge of the jaw is on the
ground.
3. Begin backing up to dig, scrape, level, or fill an area.
4. Lower loader arms to make a deeper cut and raise
loader arms to make a shallower cut.
5. Tilt top of hitch plate as needed to angle blade for
your operation.
6. Allow excess material to discharge over the top of the
jaw when scraping and leveling.
7.
If material needs to be removed, close the jaw to
capture accumulated material and remove it.
