SIGNAL WORDS:
This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the
probable seriousness of those injuries, if the product is misused in the ways described. Other signal
words call attention to uses of the product likely cause property damage.
The signal words used appear below along with the meaning of each word:
Identifies a hazardous situation which, if not avoided, WILL result in DEATH or
SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.
Identifies a hazardous situation which, if not avoided, COULD result in DEATH or
SERIOUS INJURY.
Indicates a hazardous situation which, if not avoided, COULD result in MINOR or
MODERATE injury.
Identifies practices likely to result in product/property damage, such as operation that
might damage the product.
Each person who assembles, installs, uses, or maintains this product should read the entire manual in
advance and fully understand the directions. If after reading the manual you do not understand an
instruction, ask your supervisor or employer for clarification, because failure to adhere to the directions in
this manual might result in serious personal injury.
Safe Use Recommendations:
Vestil diligently strives to identify foreseeable hazards associated with the use of its products. However,
material handling is inherently dangerous and no manual can address every conceivable risk. The end-
user ultimately is responsible for exercising sound judgment at all times.
Electrocution might result if any part of the dumper contacts electrified wires. Reduce the likelihood
that platform occupants or bystanders might be electrocuted by applying common sense:
DO NOT contact electrified wires with any part of the dumper;
DO NOT install the HBD in an area where contact with electrified wires is likely;
DO NOT use the dumper close to electrified wires or other sources of electricity;
Before using the dumper, always inspect the usage area for unusual conditions that require special precautions.
Material handling is dangerous. Improper or careless operation might result in serious personal
injuries sustained by the operator(s) and/or bystanders. Work platform users should conform to the following:
ONLY use the box dumper as a means for mechanically emptying appropriately sized (see “Load the dumper” on
p. 4-5) boxes, crates and other containers. ALWAYS properly load the dumper according to the directions on p. 4-5.
DO NOT use a damaged dumper. Examples of structural damage include: broken container restraining tube,
broken fork pockets, and holes caused by rust or corrosion. Inspect the dumper before each use according to the
inspection instructions on p. 5. DO NOT use the HBD unless it passes every element of the inspection, or until
authorized maintenance personnel approve the dumper for service.
Inspect the unit before each use according to the inspection instructions on p. 5.
DO NOT stand beneath or travel under the dumper chute while it is elevated or allow others to do so.
DO NOT use UNLESS each label shown in Fig. 8 on p. 14 is affixed to the dumper, undamaged and readable.
DO NOT exceed the maximum rated load (capacity) of the dumper. The weight of the container to be dumped
plus the weight of its contents must not exceed the maximum rated load of the dumper.
DO NOT modify the box dumper in any way UNLESS you first obtain express, written approval from Vestil.
Unauthorized modifications might make the dumper unsafe to use, and could result in operator and/or bystander
injury.
DO NOT fill the hydraulic system with brake fluid or jack oils. Only fill the hydraulic system with
either anti-wear hydraulic oil, viscosity grade 150 SUS at 100°F (ISO 32cSt at 40°C) or Dexron transmission fluid.

Installation instructions
Responsibility for compliance will local building code(s) requirements, municipal/county ordinances, etc. rests
exclusively with the end-user. The instructions that appear below are recommendations about essential, minimum
steps necessary for safe installation. If law enforced where the dumper is used requires you to depart from these
directions, Vestil is not responsible for any consequential damages sustained as a result of the installation.
Installation requires at least:
Forklift rated for loads equal to the net weight of your HBD model (see Table on p. 2);
Lag bolts: ½ in. by at least 4in. (length) [approximately equivalent to 1.3cm by at least 10.2cm]
Masonry drill and ½ in. masonry drill bit
Wrench: ½ in.
Grout and steel shims
Power supply circuit: matched to motor voltage and current requirements (see Label #250 in FIG. ## on p. ##).
NOTE: End-user is responsible for providing overcurrent and short circuit protection.
Step 1: Position the dumper as desired
with a forklift.
Step 2: Drill holes approximately 4in.
(10cm) deep.
Step 3: Secure the dumper to the floor by
inserting the lag bolts through the (5/8 in.)
bolt holes in the anchor brackets (dotted
lines in FIG. 1.
Step 4: Shim and/or grout the sides of the
frame.
Step 5: Connect the power cord to the
power supply.
Operation instructions
Load the dumper:
1. Use only properly sizes waste containers: HBD’s are designed to dump open-top containers. Container width
should be at least ½ the width of the chute.
2. Place the container inside the chute: the back of the container should rest against the back of the chute.
3. Insert retaining tube: to prevent the container from sliding out of the chute along with the trash, install the
container-retaining tube through the sockets that are most closely matched to the height of the container. The
top of the container should not be more than 5 inches (~12½ cm) below the tube.
4. Dump the container: press the “UP” button on the pendant controller to raise the chute to the dumping position.
The cylinders will extend, which raises the chute, only while the operator presses the “UP” button. When the
operator releases the UP button, the chute will maintain its position as of the instant the button is released.
NOTE: If the net weight of the container and its contents exceeds the maximum rated load of the dumper, a relief
valve (incorporated into the hydraulic system) will open. While the relief valve is open, the hydraulic cylinders will
not extend, and therefore the chute will not raise/dump.
5. Return the chute to the loading position: press the “DOWN” button on the controller—the cylinders will retract,
which pulls the chute toward the ground. If the DOWN button is released before the chute is completely retracted,
it will maintain its position. Always completely lower the chute.
Models rated for up to 6,000 pounds (2,727kg) include a lower limit switch that prevents the cylinders from
retracting more than necessary to lower the chute to the loading position.

Step 6: Run the dumper through several
complete cycles. Press the “UP” button o
f
the hand controller until the chute raises
as far as it can, and then lower i
t
completely. Repeat the cycle a few more
times to confirm that the product operates
properly.
Step 7: Check the oil level in the reservoir.
Fully raise the chute (to the 45°) “dumping
position,” and then observe the level of oil
in the reservoir. The surface of the oil
should be 1 to 1½ inches below the fill
hole.

Inspections
Before each use, inspect the listed components:
1. Wires: look for frays;
2. Hydraulic system: check lines for chafes, pinches or leaks, and
the reservoir for punctures or leaks;
3. Container-restraining tube (and the openings in the chute that
receive each end of the tube): damage deformation, looseness
of fit;
4. Frame: check the cylinder brackets, vertical and horizontal
frame members, horizontal cross-member, and angle cross
member, hinge blocks, and pivot shaft and spacer assemblies
for cracking, deformation and corrosion;
5. Limit switches: verify normal function. The chute should not
rotate beyond approximately 45 degrees or below 0 degrees.
(See FIG. 1).
Also listen for unusual sounds that might indicate binding or
grinding during operation and watch for erratic movement(s).
Contact maintenance personnel if you observe any unusual
sound or movement and do not use the dumper until approved for
service.
At least once per month, inspect the dumper as follows:
1. Oil level: fully raise the chute (to the 45°) “dumping position,” and then observe the level of oil in the reservoir. The
surface of the oil should be 1 to 1½ inches below the fill hole.;
2. Pivot points: check the dumper for excessive wear at the pivot points between hydraulic cylinders and cylinder
brackets, and between pivot shafts and hinge blocks;
3. Floor connection points: anchor bolts should prevent the frame from lifting off of the ground during chute
operation. Concrete around each anchor bolt should be intact—no cracking or flaking;
4. Fasteners: check each fastener connection. Tighten any loose connection;
5. Hoses and wires: check each wire and hose for damage (fraying, binding, etc.);
6. Labels: labels should be easily readable and undamaged, affixed to the dumper in the locations as shown in FIG.
8 on p. 14.
7. Container-restraining tube (and the openings in the chute that receive each end of the tube): inspect the tube for
damage deformation, looseness of fit.
At least once per year, change the hydraulic oil if it becomes gritty or looks milky (water present in the oil). With
the chute in the fully lowered position, drain the oil and replace it with either Dexron transmission fluid or anti-wear
hydraulic oil, viscosity grade 150 SUS at 100°F (ISO 32 cSt at 40°C.
Power unit operation
The box dumper utilizes an electric motor directly coupled to a gear pump to pressurize the hydraulic fluid. Fluid
pressure moves the cylinders up or down, and this movement performs the work required to raise and lower the
chute. A hydraulic manifold bolted directly onto the gear pump houses the hydraulic control components; each
component is rated for 3,000psi working pressure.
Important components of the power unit include:
Electric motor: when ordered, the owner of this box dumper selected either a single-phase or three-phase AC
motor. Regardless of phase capabilities, every motor is dual-voltage capable.
Gear pump: shaft coupled directly to the shaft of the electric motor. Several displacements are available are
correspond to the horsepower of the motor selected.
Check valve (HBD-2-## and HBD-4-## models): prevents backflow of fluid through the pump and thereby allows
the chute maintain a given position indefinitely.
Pressure relief valve: opens a path for fluid to flow back to the reservoir if fluid pressure exceeds 3,000psi.
Lowering solenoid valve: electrically-operated cartridge valve with an integral screen to keep contaminants from
entering the valve.
Counterbalance valves (6,000lb. rated load models only): allow smooth motion in double-acting hydraulic circuits.
Pressure compensated flow control spool (2,000lb. & 4,000lb. rated load models only): located beneath the
lowering valve, and regulates the fluid flow to the reservoir. This component allows the table to lower at the
constant rate independent of the weight of the dumper and contents. Several sizes are available.
Hydraulic cylinders: 2,00lb. and 4,00lb. rated load models utilize displacement style cylinders. Each cylinder
includes a bleeder valve (located at top end) for removing air from the hydraulic system.
6,000lb. HBD models use double action cylinders.

Velocity fuse: a safety device installed in the hose port of each cylinder. If a hose is punctured while the HBD is in
use, the velocity fuse closes automatically. The chute remains stationary until pressure is reapplied to the system.
Hydraulic fluid: HO150 hydraulic fluid. To replenish the fluid, add anti-wear hydraulic fluid with a viscosity grade
of 150 SUS at 100°F (ISO 32 @ 40°C) like AW-32 or Dexron transmission fluid.
Sequence of operation:
To tilt the chute, press the “UP” button. The motor turns and spins the gear pump. Oil flows out of the reservoir,
through the suction filter and into the pump.
2k & 4k rated load models: pump propels oil through the check valve to the lift cylinders.
6k rated load models: pressurized oil flows through the energized directional valve RT and into the blind end of
the lift cylinders; then oil is pressed out of the rod end and through a counterbalance valve 2CB. Counterbalance
valves prevent jerky movement as the chute reaches peak elevation (45° with horizontal).
Releasing the UP button during operation will immediately halt all chute movement.
Additionally, an upper travel limit switch automatically turns off the motor when the chute reaches a preset 45° tilt
angle.
To lower the chute, press the “DOWN” button.
2k & 4k max. rated load models: lowering valve opens which bypasses the check valve and allows oil in the
cylinders to flow to the reservoir (through return hoses).
6k max. rated load models: The motor turns and the pump pushes the pressurized oil through the energized
directional valve LT and into the rod end of the lift cylinders. Oil flows from the blind ends of the cylinders and
through counterbalance valve 1CB, which regulates lowering speed and smoothness. A lower limit switch turns off
the motor when the chute is fully lowered.
Releasing the DOWN button during operation causes all chute movement to stop. The chute will remain in the
same position until you press the DOWN button again and allow it to lower completely.
If the chute slowly loses elevation without pressing the DOWN button, remove, inspect, and clean the lowering
cartridge valve as follows:
1. Lower the chute completely and unplug the AC cord.
2. If loaded, remove the container from the chute.
3. Remove the nut that fastens the solenoid coil to the valve stem, remove the coil, and then unscrew the
valve from the manifold.
4. Inspect the valve for blockage(s).
5. Inspect o-rings and back-up washers for cuts, tears, etc.
6. Submerge the valve in mineral spirits or kerosene and use a thin tool, such as a small screwdriver or a
hex wrench, to push the poppet in and out several times from the bottom end of the valve. The valve
should move freely, about 1/16” between the closed and open positions. If the poppet sticks, the valve
stem might be bent. Replace the poppet if it doesn’t free up after cleaning.
7. Remove mineral oil from the valve with compressed air.
8. Move the poppet in and out.
9. Inspect the bottom of the valve cavity in the manifold for foreign matter.
10. With the thin tool, press the middle of the flow control spool, which is located in the bottom of the
cavity. It should move down and up smoothly.
11. Reinstall the valve (in the manifold) and tighten the valve with 20 lb-ft of torque.
If the chute lowers extremely slowly, air in the cylinders might be the culprit. Air closes the velocity fuse, which
prevents oil from flowing out of the cylinders. To bleed the air from the system:
Fully lower the chute;
If loaded, remove the container from the chute.
Locate the bleeder valve located at the top of each cylinder (it looks like a grease zirk). Bleed one (1) cylinder at
a time. Hold a rag over the valve and open it about 1/2 turn with a 3/8” or 5/16” wrench. Oil and air will sputter
from the valve. Jog the motor by pressing the UP button for just a second. If air continues to escape from the
bleeder valve, jog the motor several more times. Wait at least 5 seconds between successive jogs.
As soon as air no longer is observed and only a clear stream of oil flows from the bleeder valve, close the valve.
Check the oil level in the reservoir. If the surface of the oil is lower than 1 to 1½ in. below the fill hole, add oil until
it is between 1 and 1½ inches of the fill hole.

1a.Transformer fuse is blown.
b. No supply voltage.
c. Upper-travel limit switch is
engaged or bad.
d. Faulty connection in control
circuit.
e. Bad control transformer.
f. Open motor relay coil.
g. (DC units) Low battery voltage.
1a. Test with meter; replace if bad.
b. Test with meter. Check fuses,
breakers, and overloads to determine
the cause.
c. Inspect and test switch. Replace if
bad.
d. Test all parts of circuit with meter.
e. Check for 24 VAC; replace if bad.
f. Test with meter; replace if bad.
g. Test with meter. Charge battery if
low (is motor relay LED on?)
2. Motor runs properly, chute doesn’t
move. Motor and pump not noisy.
2a. Incorrect motor rotation.
b. Pump failure.
c. Low hydraulic fluid level.
2a. Verify motor shaft rotates
counterclockwise.
b. Consult factory for replacement.
c. Ensure reservoir is filled.
3. Motor or control enclosure hums,
chatters, or buzzes, or some type of
squeal can be heard; the chute
does not move, or the chute moves
only slowly.
3a. See 2b above.
b. Excess voltage drop to motor
due to power wire size too small,
wire run to long, or incoming
voltage too low.
c. Motor is “single-phasing”.
d. Pressure relief opening at full
pressure.
e. Contamination holding open
the lowering valve or the check
valve.
3a. Same as 2b.
b. Check power installation for
adequacy. Check incoming voltage
while motor is running. Correct
problem(s).

on one phase; correct.
d. Check for structural damage or
binding of the rollers, etc.
Check for chute overload condition.
e. Remove and inspect. Clean the
valve with mineral spirits.
4. Chute elevates, then drifts down. 4. See 3e above. 4. Same as 3e.
5. Chute lowers too slowly. 5a. Flow control spool is stuck.
b. Pinched hose.
c. Velocity fuse locking (chute
only slowly creeps down).
5a. Remove plug from FC port; push
down on the center of the flow spool to
ensure it moves freely.
b. Check pressure, supply, and return
hoses for kinks.
c. Same as 7 (below).
6. Chute lowers too quickly. 6a. See 3e.
b. Flow control spool is stuck.
