FINISHING OFF
Ensure the ram’s pressure release valve is closed (turn fully
clockwise).
The force exerted by the hydraulic ram (up to a maximum
of 1,500kg) creates a potentially dangerous situation, so
make sure that any seal has been broken before lifting.
If great force is used, the assembly and manhole cover
will spring up.
NEVER place yourself in a position where you could be hit
by the equipment or cover as the cover lifts.
Using the pump handle, gradually pump the ram until
the manhole cover lifts.
Take your time and don’t overdo it. You are more likely to
have an accident if you are tired or rushing.
Once raised, manoeuvre the unit away from the manhole
and lower the ram, by turning the pressure release valve 1 turn
anti-clockwise.
When replacing the cover, simply reverse the removal
procedure.
EQUIPMENT CARE
Never push the equipment beyond its design limits.
If it will not do what you want with reasonable ease and
speed, assume you have the wrong tool for the job.
Contact your local HSS Lift & Shift Depot for advice.
Keep the equipment clean, you will find this less of a
chore if you clean it regularly, rather than wait until the end
of the hire period.
When not in use, store the equipment somewhere
clean, dry and safe from thieves and unauthorised users.
Replace the manhole cover and disconnect all keys
and clamp frames.
Dismantle the unit and give everything a thorough
clean ready for return to your local HSS Lift and Shift.

For advice on the safety and suitability of this equipment
contact your local HSS Lift & Shift Depot.

Box
Section
Pressure
Release Valve
Take the main body frame and slide the crossbeam
through the end mounting box section.
Open the ram’s pressure release valve by turning
anticlockwise and once the ram is fully retracted,
close the valve.
Slide one lifting hook onto each end of the
crossbeam so that the hook is facing down with its
opening toward the ram.
Next, slide a castor assembly onto each end of the
crossbeam with the castors fork pointing horizontally
away from the ram. Secure the castor assembly to the
crossbeam by turning the thumbscrews clockwise, do
not overtighten.
Wheel the unit to the manhole cover and select
the correct key.
If using 2 keys…
Insert both keys into the keyways of the cover then
place their loop over each of the lifting hooks. Adjust
the distance between each hook as necessary but keep them
an equal distance from the centre of the cross bar.
If using 4 keys…
BASIC TECHNIQUES
Using 4 Keys
Loop
Clamp Frame Key
Wing Nut
Loop
Select the most suitable clamp frames and attach each to
one side of the cover using 2 keys on each. Insert each key
through the slots in the clamp frame and into the lifting holes,
turn the key 90 degrees then wind down the wing nuts until
under pressure.
Place the loop of each clamp frame over each of the lifting
hooks. Adjust the distance between each hook as necessary but
keep them an equal distance from the center of the cross bar.
Whichever you are using…
DO NO attempt to lift a cover using a single key.
Make sure that the lift pressure is balanced between each
lifting hole to ensure a vertical lift. Uneven pressure will
cause the cover to twist and could damage the equipment.
