SAFETY
WARNING! Follow these safety instructions to
avoid any personal injury.
• Do not use a malfunctioning or structurally
damaged hopper. Examples of structural damage
include:
a. damage to the hopper release mechanism (that
allows the hopper to dump);
b. broken fork pocket(s);
c. damaged main connection pin; or
d. broken welds. Inspect the hopper before each
use according to the inspection instructions on
page 6. Do Not use the hopper unless it passes
every part of the inspection.
• DO NOT use the hopper if the safety chain is
damaged or absent.
• DO NOT lift the hopper until it is securely connected
to the carriage of the fork truck with the safety chain.
• DO NOT fill the hopper with a load weighing more
than its capacity (2,000 lb.).
• DO NOT stand beneath or travel under the hopper
at any time. Do not permit any person to stand
beneath or travel under the hopper.
• Hoppers with lifting lugs can be lifted with overhead
hoists and cranes. DO NOT lift a hopper unless the
chute is securely latched to the frame. The hopper
must not be able to rotate while it is suspended.
• DO NOT allow people to ride on or in the hopper.
• DO NOT use the hopper if any product label is
unreadable, damaged, or missing. Contact Uline
Customer Service at 1-800-295-5510 to order
replacement labels.
• Always apply proper (fork) lift truck operation
practices learned during your training program.
Before raising the hopper from the floor, tilt the (forklift)
mast toward the cab of the truck to ensure that the
hopper will not slide towards the tips of the forks.
• DO NOT modify the hopper in any way!
Modifications might make the hopper unsafe to use
and automatically void the limited warranty.
• DO NOT dump the hopper unless every person in the
vicinity is safely behind the forklift truck.
• DO NOT dump the hopper if the forklift is facing
down a slope. Only dump the hopper while parked
on a level surface.
• ALWAYS engage the caster brake when the hopper
is stationary or not in use.

LOADING
WARNING! Do not exceed the load rating or fill
the hopper above the top of the sides. Serious
personal injury (or property damage) could
result from overloading the hopper.
DUMPING
1. Mount the hopper on the forks of a lift truck and
secure it to the carriage with the safety chain. Wrap
the free end of the chain around the lift carriage;
then fasten the quick link to a link in the chain. The
chain must be taut (no slack) to prevent the hopper
from sliding on the forks.
2. Store the handle of the release cable within reach
of the forklift operator. For example, hook the cable
to the frame of the forklift cab. Make sure that there
is plenty of slack in the cable to avoid accidentally
releasing the chute.
3. The chute cannot dump unless the latch is unlocked.
To unlock the latch, pull the finger tab at the top
end of the latch lock bracket until the bracket
disengages the latch bar (See Figure 10)

Low profile hoppers are designed for indoor and
outdoor use in most industrial and commercial
settings. They should only be used to collect and dump
non-hazardous wastes.
1. Confirm the hopper chute is solidly latched to the
base frame before filling the chute with refuse.
2. When the hopper is stationary, engage the caster
brake.

6. Latch the chute to the base.
a. Manually: Slowly lower the forks until the hopper
rests on the ground. The chute will pivot towards the
frame. Press the back end of the chute onto the
base until the latch lever engages the latch bar.
b. Using the forklift: Raise the fork tips by tilting the
forklift mast toward the cab. Then, back away
from the dumpster. Slowly lower the forks until the
front end of the chute contacts the top of the
side of the dumpster. Continue to slowly lower
the forks until the chute pivots onto the base
frame. You should hear the latch lever snap over
the latch bar. Confirm that the chute is securely
latched by raising the forks. The chute should not
rotate. If necessary, lower the forks completely
and manually latch the chute to the frame.
7. Lock the latch by reversing the process described in
step 3.
WARNING! DO NOT move the hopper until the
latch is locked!
5. Dump the contents of the hopper by releasing the
chute. To release the chute, pull the release cable.
The chute will pivot about the dump axis.

MAINTENANCE
WARNING! If an inspection reveals issues,
restore the hopper to normal operating
condition BEFORE using it again. DO NOT use
a structurally damaged hopper. Structural
damage includes but is not limited to,
cracked welds, warping or deformation of the
chute, pivot points, or the supporting frame,
particularly the fork pockets.
DAILY INSPECTION
Before each use, inspect the following components:
• Release cable – Look for fraying, birdcaging,
thinning.
• Hopper chute or base frame – Check for damage,
deformation, corrosion or severely rusted regions.
• Pivot points – As the chute rotates (after releasing
it), listen for unusual noise and watch for binding as
the chute rotates. Also look for distortion of the axle
points or axle receivers.
• Release/latch mechanisms – Test the chute release
mechanism (lock release, lever assembly). The
torsion spring should cause the lever assembly to
automatically recoil and firmly latch the chute to the
frame.
• Safety chain – Check the chain for damaged links
(broken, cracked, elongated).

MONTHLY INSPECTION
Inspect the following components at the least once per
month. Replace any component that is excessively worn
or no longer operates normally:
• Pivot points – Look for excessive wear, warping, or
other damage to the release lever pin, pin brackets,
axle pins and axle receivers. Listen for unusual
noises and watch for irregular movement. Remove
dirt and debris from areas that could affect the
hopper's dumping motion.
• Fasteners (bolt, locknuts, axle pins, cotter pins,
retaining rings) – Inspect for looseness and wear.
• Casters – Check for looseness, excessive wear or
damage to the casters, caster bearings, mounting
brackets and hardware. Confirm that the brake
functions properly.
• Release Mechanism – Verify the mechanisms
function properly:
a. Torsion spring firmly latches the lock release lever
assembly to the chute.
b. The latch lock bracket should seat on the latch
bar unless manually disengaged.
• Chute – Examine the chute. The structure should be
rigid and square without corroded holes or severely
rusted areas.
• Supporting frame – Examine the frame. It should be
rigid and square, welds should be intact and fork
pockets should be square and sound.
• Labels – All labels must be applied to the hopper
in the locations shown in the labeling diagram on
page 4.
WARNING! The end user should understand
the significant difference between necessary
adjustments and repairs, and modification.
Adjustments are simple corrections that restore
the hopper to normal operating condition,
such as tightening loose fasteners, or removing
dirt or other debris from the surface. Repairs
involve removing worn parts and installing new/
replacement parts.
A modification is a change that alters the
hopper from normal operating condition, such
as bending the frame or removing a part
or several parts. NEVER modify the hopper.
Modifications automatically void the Warranty
and might make the hopper unsafe to use.
c. Lever assembly pivots smoothly and securely
engages the latch bar.
