LOADING INSTRUCTIONS
The load capacity rating as inscribed on the
nameplate of your unit designates the net capacity,
assuming the cradle is aligned at the center of the
drum. This capacity must never be exceeded, as
permanent damage or injury may result.
OPERATING INSTRUCTIONS
DRUM STACKER
Remove Hydraulic Drum Stacker (HDC-
450), from the crate. Check carefully for damage
and report any damage immediately. When using
the Hydraulic Drum Stacker, you can either lift up
the drum horizontally or vertically.
HORIZONTAL DRUM POSITION
For horizontal drum position, lower the
cradle near floor position until you can slide in the
cradle along the side of the drum. Open carrier
cradle full width and hook cradle chain on stud.
Move the unit in until the end of the cradle touch
the end of the drum. Lock drum in place by clinching chain with ratchet tightener.
In both situations, raise the cradle until the
drum is 3 - 4 inches above the ground before
moving. It is recommended, but not required, the
drum to be moved in a VERTICAL position.
Remove control chain from box and place end of
loop near operator. When stacking, rotate drum
to the HORIZONTAL position.
Always stay clear of moving parts. The
cradle will rise as the foot pedal is pumped.
Depressing the release lever will lower the cradle
at a control rate of descent.
In the event the unit is overloaded, the
relief valve will open because of excessive pressure build up, and oil will bypass into the reservoir.
TO ROTATE DRUM:
Pull on chain, rotating drum to horizontal
position for stacking. For best control of drum
rotating angle, pay out one side of the loop while
pulling in the other.
END OF CRADLE
Figure 1
VERTICAL DRUM POSITION
For vertical drum position, rotate the cradle
to vertical position and lower the cradle until the
end of the cradle is the same height as the top of
the drum. Open carrier cradle full width and hook
cradle chain on stud. Move the unit in until the
side of the drum touches the cradle. Once again,
lock drum in place by clinching chain with ratchet
tightener.
** For model HDC-450-60, the drum is rotated
using a hand crank instead of chain crank.
** When elevation is not required, transport
the drum in the lowered position.
BOOM
The HDC-450 series may also be used as
a hoist using the boom supplied with unit. The
boom is stored conveniently on one of the lower
straddle legs. Simply remove the 3/4" diameter
pin from carriage and position boom on top of
carriage, align holes and replace pin and clip.
Lifting capacity for boom at hook position is 800
pounds. This capacity and load center must never
be exceeded.

SAFETY INSTRUCTIONS FOR THE OPERATOR
1.) The HDC-450 series has a MAXIMUM CAPACITY RATING of 800 pounds FULL, and 500 pounds
HALF-FULL, and is intended for lifting, moving, and stacking 55 GALLON steel drums. Do not exceed
these ratings as the unsafe condition that may result could cause damage or excessive wear, or make
the unit awkward to handle.
2.) Always load the unit properly. Make sure the end/top of the drum is touching the end of the cradle.
3.) When operating, loading, unloading, or maintaining your drum stacker, always use care and good
judgement, have good footing and a firm hold. Keep hands and loose clothing etc., away from all
moving parts. Never allow anyone to be below any part of a raised drum stacker, drum, or boom. Please
read all instruction THOROUGHLY before attempting to operate your new drum stacker.
4.) Do not allow drum to impact on floor, ground, or dumping station etc., or there may be damage.
5.) Never use the unit if the cradle is in need of repairs or in the case of a malfunction.
6.) Notify your maintenance personnel or supervisor in case you notice anything out of the ordinary, such
as binding, odd noises, appearance of oil, etc.
7.) Do not continue to pump on the foot pedal if the cradle is not raising. The foot pump may be
permanently damaged. Relieve system pressure by depressing the release lever.
8.) It is recommended, but not required, the drum to be moved in a VERTICAL position. When
stacking, rotate the drum to HORIZONTAL position.

PERIODIC MAINTENANCE INSTRUCTIONS
BE SURE ALL POWER IS OFF BEFORE ATTEMPTING TO WORK ON THIS EQUIPMENT!
CAUTION: SERVICE WORK SHOULD BE PERFORMED ONLY BY TRAINED & QUALIFIED PERSONNEL
(A) Before Each Use Check For The Following
1.) Oil leaks.
2.) Worn or damaged hose.
3.) Structural deformation of cradle or frame.
4.) Unusual noise or binding.
5.) Check casters for proper operation.
Do not use if there are any of the above!
(B) Monthly Inspections
1.) Check oil level. Oil should be 1" to 1 1/2" below the top of the tank with the
cradle in the fully lowered position. Add as necessary.
2.) Check for oil leaks.
3.) Check for worn or damaged hose.
4.) Check clevis and pivot points for wear.
5.) Periodically inspect all moving parts, framework, and contact areas for sign
of wears, fatigue or loosening.
Tighten, adjust or replace parts as necessary to prevent failure and
maintain proper function.
6.) Check oil cradle hinges, ratchet, pawl, chain and other moving parts
periodically.
7.) Lubricate gear-train once a month with a good grade lubricant.
There are three grease fittings on the gear block, and one grease fitting in
the idler bearing block.
8.) Check for unusual noise.
9.) Clean off dirt and debris.
10.) Make sure all warning labels are in place and in good condition (p.14).
(C) Yearly Inspection
4
Hydraulic oil should be changed at least once a year, or sooner if the oil
darkens or becomes gritty. Flush reservoir before refilling. Presence of
water is indicated if the oil turns milky. Recommended oil: AW-32
Hydraulic fluid or equal.
All maintenance work must be performed by qualified personnel with
training in the repair of electrical and hydraulic components

OPERATION
Warning:
Keep all personnel clear of the machine when it is in operation. Be certain no part of any
person or object is under any part of the platform before lowering the unit.
Caution:
Always carefully watch cradle and any load on it when it is in operation.
Do not exceed a rate of two feet per second when transporting a load with the drum stacker.
• The standard manually-powered stacker is furnished with a two-speed foot pump. Under empty or
low load conditions, the pump pushes a higher volume of fluid to the cylinder and thus lifts the platform
with fewer foot strokes. With a moderate to full load, the pump will automatically reduce its output in
order to generate the required hydraulic pressure.
• To lift the platform, simply repeatedly press the foot pump's foot treadle. To lower the platform, press
the small lever at the left corner of the pump with your toe. The unt will hold its position when the
lowering lever is released.
VELOCITY FUSE OPERATION
There is a brass velocity fuse with a stainless steel spring in the base of each cylinder. In the
event of a hydraulic hose or fitting failure, the cradle starts to lower at a fast rate. As soon as the descent speed exceeds the fuse's preset speed, the velocity fuse will shut off the oil flow and the cradle
will remain nearly stationary until pressure is reapplied (after repairs are done). This safety feature
reduces the possibility of accidental personal injury or damage to the unit or its loads. If air is introduced into the system, the velocity fuse can lock up even though no failure has occurred. To reset the
velocity fuse just activate pump by depressing the "UP" button. Remove the load and follow the
cylinder air bleed procedures on page 6.
5
Page 6
AIR BLEED PROCEDURE
If your unit descends very slowly or will not descend at all, air could be trapped in the hydraulic
circuit and must be "bled" from the system. The Hydraulic Drum Stacker (HDC-450 Series) utilizes a
"bleeder" fitting at the end of the cylinder near the cross tube. If you experience the above, follow
these directions.
1.) Remove the drum from the cradle.
2.) Raise the unit.
3.) If available, place a 1/4" plastic hose over the cylinder bleeder screw.
4.) Loosen the bleeder screw at the top of the cylinder approximately 1/4 to 1/2 turn to allow
trapped air to escape.
5.) When the cylinder is free of air, tighten the bleeder screw and remove the plastic hose.
Air can also become trapped in the foot pump.
Please refer to page 8 for the foot pump air bleed procedure.
