Section III –Unit Operation
IMPORTANT
Before using this unit, operators must read and understand this instruction manual. Failure to
observe the instructions in this manual will invalidate the warranty.
NOTE: Personal Protective Equipment (PPE) must be worn at all times, see ‘Section I – Correct
Use and Application’ for more information.
Initial Setup and Connecting to Drums
Each depalletiser is fitted with a universal drum catch which is adjustable in both height
(vertical) and reach (horizontal). This unique adjustability means that each lifter can handle a
wide variety of drum types and sizes commonly found in the workplace.
•Ensure the rack is lowered fully so that all the vertical lift stroke is available; this is done by
turning the lowering lever anticlockwise.
WARNING –DO NOT ROTATE THE LOWERING LEVER CLOCKWISE AS THIS MAY DAMAGE THE
UNIT.
•There are multiple rungs to which the drum catch can be secured, removing the lowest
pin allows removal of the catch from the rack. It can then be relocated and the pin
reinserted on a rung so that the catch is positioned below the lip of the drum.
•Manoeuvre the depalletiser using the handle, being sure to keep good posture.
Operators should move gently while manoeuvring, whilst planning ahead in good time.
Ensure that when not in use, the unit is parked on flat and level ground with the brakes
engaged.
•Line up the lifter with the centreline of the drum.

10 Operating Instructions: DTP05(-Ex)
•Lift the rack by operating the pump handle so that the catch rises above the top lip of
the drum.
•Push the unit forward so that the top hook engages the drum.
•Lower the rack slowly by turning the lowering lever anti-clockwise ensuring that the top
hook engages over the top lip of the drum and that the bottom toggle secures beneath
the drum lip.
•The drum is now ready to be lifted.
Removing Drums from a Pallet
•Pump the hydraulic handle to raise the drum to the desired height.
•Remove drum from the pallet by slowly pulling the depalletiser away.
•When clear of the pallet and transporting the drum, keep the drum as low to the ground
as is practical for transport.
•To place the drum down, simply turn the lowering lever anticlockwise. The rate at which
the drum lowers is controlled by the amount that the lever is rotated.
•Once the drum is placed on the floor, or another pallet, continue to lower the rack until
the catch goes slack, the operator can then reach forward and manually remove the
top hook from the drum.
•If the catch is lowered too far; it will be not possible to unhook from the drum. In this
instance raise the rack slightly by pumping the handle, the catch will then go slack and
the top hook will be able to be unhooked.

11 Operating Instructions: DTP05(-Ex)
Universal Drum Catch Variations
WARNING –DUE TO VARIATIONS IN THE MANUFACTURE OF DRUMS IT IS IMPORTANT THAT THE
CORRECT HOOK POSITION IS SELECTED. FAILURE TO DO SO COULD RESULT IN THE CATCH
DISCONNECTING FROM THE DRUM.
The universal drum catch has been designed so that a variety of
positions can be used to fit different sized drums. Changing the
hole that the top catch is located in increases the reach by a
further 10mm by each hole placement. The top hook must always
be placed in the shortest possible position. By removing the top
pin, the top hook can be turned over so that the sticker is upside
down. This gives the top hook a further 5mm of reach. Ensure that
the pin is reinserted and secured before lifting. If required, the
retractable support pad can be folded out to keep a drum in a
more vertical orientation.
The following hole positions are for guidance only, every drum should be assessed individually
and engaged with by following the instructions provided.
