A CAUTION is used to indicate correct operating or maintenance procedures and practices to
prevent damage to, or destruction of equipment or other property.
A WARNING indicates a potential danger that requires correct procedures or practices to avoid
personal injury.
A DANGER is only used when your action or lack of action may cause serious injury or even
death.
IMPORTANT: Operator must be competent in
the use of hydraulic equipment. The operator
must have read and understood all instructions,
safety issues, cautions and warnings before
starting to operate the Christie equipment.
WARNING: To avoid personal injury and
possible equipment damage, make sure all
hydraulic components are rated to a safe
working pressure of 700 bar (10,000 psi)
WARNING: Do not overload equipment.
Overloading causes equipment failure and
possible personal injury. The risk of
overloading can be avoided by using the
Christie Hand Pump, which has its safety valve
set to 700 bar by the factory. If alternative
pumps are used, ensure they are rated at a safe
working pressure of 700 bar (10,000 psi).
CAUTION: Make sure that all system
components are protected from external sources
of damage, such as excessive heat, flame,
moving machine parts, sharp edges and
corrosive chemicals.
CAUTION: Avoid sharp bends and kinks that
will cause severe back-up pressure in hoses.
Bends and kinks lead to premature hose failure.
Do not drop heavy objects onto hoses. A sharp
impact may cause internal damage to hose wire
strands; applying pressure to a damaged hose
may cause it to rupture. Do not place heavy
weights on the hoses, or allow vehicles to roll
over the hoses; crush damage will lead to
premature hose failure.
WARNING: Immediately replace worn or
damaged parts with genuine Christie parts.
Christie parts are designed to fit properly and
withstand rated loads. For repair or maintenance
service contact W. Christie (Industrial) Limited
DANGER: To avoid personal injury keep hands
and feet way from the tool and workpiece during
operation.
WARNING: Always wear suitable clothing and
Personal Protective Equipment (PPE).
DANGER: Do not handle pressurised hoses.
Escaping oil under pressure can penetrate the
skin, causing serious injury. If oil is injected
under the skin, seek medical attention
immediately.
WARNING: Never pressurize unconnected
couplers. Only use hydraulic equipment in a
connected system.
IMPORTANT: Do not lift hydraulic equipment
by the hoses or couplers. Use the carrying handle
or other means of safe transport.
CAUTION: Do not operate the equipment
without lubricating all moving parts as in section
7. Use only high pressure molybdenum
disulphide grease.

4 –TECHNICAL DATA
The CHRISTIE WCLW18TE Hydraulic Vertical Lifting Wedge will generate 18 Tons (180 kN) lifting
force from 10,000 psi (700 bar) of hydraulic pressure. The tool requires a minimum access gap of 9.5 mm
(0.37”) on the first step and will lift vertically.
Using two WCLW18TE wedges will allow a lift of 36 Tons
Using four WCLW18TE wedges will allow a lift of 72 Tons

5 –HOW THE TOOL WORKS
1) The hydraulic hose and hand pump are attached to the tool
and the tool is inserted into the access gap
2) The hand pump is primed which powers the hydraulics
that lift the load
3) The load is secured using the safety block
6 –INSTALLATION AND OPERATION
6.1 STANDARD INSTALLATION AND OPERATION
The operation procedure is exactly the same for both the WCLW18TE Mini and Standard Kits. The
WCLW18TE Mini Kit does not contain either a 10,000 psi (700 bar) hydraulic hand pump or a 10,000 psi
(700 bar ) hydraulic hose. These items will come from the user’s inventory.
1) Assemble the kit by connecting one end of the
hydraulic hose to the hand pump, and the other end
to the hydraulic cylinder.
2) Ensure the access gap under the item to be lifted
measures 9.5 mm (0.37”) or greater.

5
3) Place the wedge under the item to be lifted. The step
to be used must be fully inserted into the access gap
- ensure that the heel of the step is in contact with
the outer surface of the object to be lifted and that
the wedge is positioned centrally.
4) Close the return valve on the hand pump (by turning
clockwise) and advance the wedge by priming the
pump.
N.B. The HP350S Hand Pump has a self contained non-vented
oil system. This means that the pump will function without the
need for an air vent to be opened. This allows the pump to be
used vertically, horizontally or upsides down should the
situation require. Having no open vent eliminates the risk of
hydraulic oil spillage during use.
5) Once the item has been lifted to the desired height, or to the
maximum height on the step used, the safety block should
be inserted into the gap. Secure the load by releasing the
pressure onto the block.
6) If required, the wedge should then be re-inserted on the next step and steps 3 - 5 repeated to lift
the item further.
Never place fingers under an item being lifted. Always ensure that both the wedge and
the safety block are inserted under the item until the heel of the step is in contact with
the side of the item to be lifted and the step is positioned centrally (see Installation and
Operation step 3)
Care should be taken not to drop any of the component parts when removing them from
the lifted load. This action will prevent injuries to either the operator’s lower limbs, or to
passers by.

6
6.2 –USING THE STEPPED BLOCK ASSEMBLY
The Christie Stepped Block enables the WCLW18TE Hydraulic Vertical Lifting Wedge to be used to lift
an item with a larger gap, and will lift the item further with less penetration
1) Attach the stepped block to the tool using the M6
countersunk screw.
2) Insert the tool under the item to be lifted. Ensure
there is a minimum hold of 15 mm (0.59”) and that
the full width of the block is used.

7 –EXAMINATION, MAINTENANCE AND STORAGE
On return from each job and before allocation against subsequent work the completeness of the
Christie WCLW18TE kit must be established and items examined to ensure that they are
serviceable.
Any missing or damaged items are to be replaced as soon as possible and prior to the tool being
used again.
Store the tool in a cool dry place and ensure all machined surfaces are greased
Grease all moving parts each and every time the tool is used:
Greasing the wedge:
Remove the grease nipple from the handle of the tool
Screw the grease nipple into the jaw, attach the grease gun
and squeeze grease into the wedge
Screw the grease nipple into the base of the tool, attach the
grease gun and squeeze grease into the wedge
OR
Connect the hose to the wedge and advance the wedge
forward, smear grease onto the surfaces of the wedge
Greasing the slide pins:
Simply smear some grease into the slots. Also
ensure the slide pins are free from grit.

10 –TROUBLESHOOTING
PROBLEM
CAUSE
SOLUTION
Hoses are connected but the tool does
not advance. The pressure on the pump
handle is minimal.
The release valve is in the retract (open
position).
Close the release valve.
Hoses are connected and the pump
quickly reaches maximum pressure but
the tool has not advanced.
One or more of the connectors are not
fully tightened and the hydraulic oil
cannot pass through from the pump to
the cylinder.
Check all connectors are fully tightened
and the release valve is in the fully
closed position.
Hoses are connected and the tool
advances with maximum pressure on
the pump handle but the load will not
lift.
The pressure required to lift the load is
greater than that of the tools you are
using.
Add another tool and try again.
Hoses are connected and the tool
advances but there is minimal pressure
on the pump handle and the handle is
rising back of its own accord.
There is dirt or a damaged valve seat
within the pump unit.
The pump should be sent to W. Christie
(Industrial) Limited for repair.
PROBLEM: The wedge is advancing but does not reach full pressure
Air could be
present in
the hydraulic
system
Use the airlock removal procedure as follows:-
1. Connect the hand pump to the tool with the hydraulic
hose
2. Close the release valve on the pump, and prime the
pump until the hydraulic cylinder is fully extended and a
small pressure is achieved
3. With the hand pump held above the tool and the tool in
an upright position, open the release valve causing any air
that is within the system to be forced up through the pump
and vented into the oil reservoir
4. Repeat steps 1 - 3 three or four times to ensure that all
air is removed from the system and the tool will reach full
working pressure
5. Disconnect the hand pump from the hydraulic hose, grip
the base plate of the hand pump body in a vice with the
pump body vertical and the main handle at the top
6. Remove the four nuts holding the main handle and lift
off
7. Grip the refilling plug with pliers and extract it by
pulling and twisting simultaneously. Ensure the reservoir
body is held down when removing the refilling plug as
pulling up on the reservoir body will release the bladder
within, and oil will spill out.
8. Fill the reservoir to the top with a good quality hydraulic
oil of the grade 32 cSt
9. Reinsert the refilling plug, wipe away any oil, and
reassemble by reversing the disassembly process
