SAFETY PRECAUTIONS
WARNING!
As with all machinery, there are certain hazards involved with their operation and use. Exercising respect and
caution will considerably lessen the risk of personal injury. However, if normal safety precautions are
overlooked or ignored, personal injury to the operator or damage to property may result.
•Ensure the site selected is large enough to accommodate the lift, including a safety area,
and with adequate height clearance, taking into account the size of vehicles expected to
be worked on. (see Assembly & Installation, p6).
•Ensure the area on which the base is mounted is flat and level, and of sufficient strength to
adequately support the weight of the lift and vehicle, and is capable of recieving and
securing the foundation fittings. (see Assembly & Installation, p6).
•Ensure adequate lighting is provided throughout the entire area.
•ALWAYS wear shoes with non-skid soles and metal or reinforced toe-caps.
•ALWAYS wear protective head cover, and protective eye shield.
•DO NOT wear jewellery which may get caught in moving parts. Long hair should be contained.
•NEVER exceed the load for which the machine was designed. If the load capacity and
other warning labels become defaced or illegible, have them replaced. (Contact your Clarke
dealer for replacements).
•Before operating,ensure that all bolts, pins and securing devices are correctly in place and
in good condition. Check for signs of cracked welds, bent or loose pins or other signs of
structural damage. Do not use if any of these conditions exsist. Ensure repairs are carried out
by qualified persons only, or contact your nearest Clarke dealer.
•Use ONLY those fittings and fixtures supplied. NEVER substitute bolts or pins or other
components, unless they are direct replacements from Clarke International.
•DO NOT allow any person to operate the machine unless they are completely familiar with
all aspects of operation and have read this manual thoroughly.
•DO NOT use the machine for lifting people or for any other use other than that for which it
was designed.
•Ensure the machine is properly maintained at all times (see Maintenance).
•If the machine has been subjected to an abnormal load or shock, remove it from service
immediately and have it fully inspected by a qualified person. If necessary, refer to your
Clarke dealer.
•Before loading the machine, adjusting the arms etc., ensure the ON/OFF switch is set to
the ‘O’ (OFF) position.
•Do not reverse a vehicle into position on the lift, unless it is rear engine drive, as the Short,
Hinged Arms, at the rear of the lift, must always support the engine.
•Before locating the lifting arm pads on the lifting points, check to ensure the rubber pads
are free from oil or grease which could cause the pad to slip during operation. Never raise a
vehicle without the rubber pads in place. Replace them if they become damaged
•Ensure the vehicle being lifted is completely stable and the lifting arms are located on the
recommended lifting points ONLY. If in doubt, ALWAYS consult the vehicle handbook to
determine where the lifting points are located.
•NEVER operate the machine with any guard or cover removed.
•Ensure that no equipment is connected to the vehicle when raising or lowering.
4
•During the lifting process, ensure the load remains parallel to the ground. Should it tilt, stop
lifting immediately, lower the load and investigate the cause.
•ALWAYS keep a constant check whilst lifting to ensure that there is sufficient height clearance,
particularly in the event of an unusually large vehicle.
•NEVER allow any electric cables to pass through or rest on the structure of the lift. If they
should become frayed or damaged in any way, the lift could become live, with serious
consequences.
•Before lowering the lift, ensure that all personel, tools and other equipment used, is moved
well clear, into the safety zone.
•When operating the machine, the operator and any persons in the vicinity should stand well
clear - in the safety zone, (see Installation), and constantly checking to ensure that no
obstacle prevents progress of the lift.
•DO NOT allow anyone to stand beneath the lift until it has stopped, is perfectly stable, and
the ON/OFF switch is set to the ‘O’ (OFF) position.
•DO NOT remove a vehicle until all arms are swung clear.
•NEVER board the vehicle for any purpose when it is in a raised position.
•Never modify the lift in any way.
•ALWAYS ensure the power to the machine is switched OFF before maintenance or servicing.
•When the machine is not in use, the lift should be lowered to the ground and the supply to
the machine should be switched OFF. The ON/OFF switch on the control panel should be in
the ‘O’ (OFF) position, and the switch padlocked in place.
FEATURES
This machine has been designed with safety in mind and complies with all relevant European safety
standards.
The lifting arms are operated by screws, one in each column, driven by an electric motor. The motor
drives the Drive Screw via drive belts, and the drive is transferred to the Driven Screw via a chain.
A single control panel, mounted on the rear of the left hand (driving) column, comprises the main
ON/OFF switch, and UP and DOWN controls.
Long Telescopic Arms are provided at the front of each column, with Hinged Arms at the rear. The
Hinged Arms must ALWAYS be supporting the engine of the vehicle. Do not, therefore, reverse a
vehicle into position on the lift, unless it is rear engine drive.
Each Arm is provided with adjustable rubber pads for locating on the vehicles’ lifting points. The
maximum height to which the arms may be raised is 1850mm (6 ft), giving adequate room to
operate beneath the vehicle.
The MINIMUM ground clearance is 125mm.

The machine should be placed on a concrete floor which is at least 160mm thick and capable of
withstanding the load of the machine and vehicle (2450 lbf/in2 min).
The surface should be perfectly flat and level. If this is not the case, metal shims must be used beneath
the base plate to ensure it is level. (see Final Adjustments - p10). The floor must be capable of
receiving and securing four M12 foundation bolts (not supplied). Please refer to ‘Assembly - Base
Frame’ for further details.
If the machine is mounted on a ‘load bearing floor’, expert advice should be sought to ensure it
is of sufficient strength to withstand the load.
There should be sufficient space for a vehicle to manouvre to ensure a straight line path on to the
lift, and the height clearance, directly above the lift, should be sufficient to ensure that no damage
could occur to a vehicle being lifted.
NOTE: Ideally, a height gauge, set to the maximum vehicle height permitted, should be erected at
the entrance to the lift.
The area must be large enough to provide a Safety Zone. The diagram below illustrates the minimum
suitable space for the machine.

IMPORTANT:
This machine should be assembled by trained personnel only.
NOTE: Unless otherwise stated,the numbers in brackets refer to the parts list item number and number
in corresponding diagram.
1. Base Frame
Position the Base Frame at the desired location,
bearing in mind that the ‘Driving Column’, i.e.
that column carrying the motor and control
panel, must be mounted so that the control panel
faces the shorter foot of the base frame. (see fig.
2), and is at the LEFT HAND REAR of the machine.
Mark out the securing bolt holes, and proceed to

install the foundation bolts.
The base frame should be secured using proper foundation bolts, size - M12 (not supplied), and the
depth of the fixing should not be less than 150mm.
Installation should be carried out by a qualified person, who
can determine the composition of the surface material and
Fig. 3
advise on the correct type of fixing required.
Bolt the base frame down, but do not fully tighten. It may be
necessary to use metal shims, between the floor and frame, in
order to ensure the frame is level. It is not necessary at this stage
to level with absolute accuracy, as this is carried out once the
FRONT
23456789
lift is fully assembled.
2. The Columns
Packing piece
Firstly, fit the Column Dust Covers (Items 35 and 36, Parts List on
page 17) - one to the top of each column, securing them each
with four self tapping screws provided.

the sides, (as this could damage the sprocket).
Ensure also that the cable, which protrudes from the channel, welded to the columns’ bottom plate
(shown in fig. 4), is not trapped between the plate and base.
Secure to the Base Frame using the four screws, and large flat washers provided,in the corner bolt
holes ONLY, leaving them finger tight at this stage. DO NOT use the centre holes.
Carry out the same procedure for the other column.
Fig. 5
3. THE CHAIN
3.1 Before attaching the chain, you must first ensure the Arm
Carriages are at the same height, measured from the columns’
Base Plate. If an adjustment is required, remove the dust cover
from the top of the Driven column and turn the hex. nut (on top
of the column, shown in fig. 5),until the carriage is perfectly in
line with that of the Drive Column. Replace the Dust Cover
3.2 Remove all but the two ‘outside’ column mounting screws and
slacken these off sufficiently so that the column may be tilted
outwards (see fig.6), in order to allow the chain to be slipped
around the sprocket.
Before tilting the column outwards however, slacken off the chain
adjuster screw, shown in fig. 7, fully, and make sure the column is
pushed in, towards the opposite column, as far as possible.
3.3 Very carefully tilt the column outwards and, as a safety
precaution, place chocks between the columns’ Base Plate
and the Base Frame as shown in fig. 6. (Should the column slip,
the chocks will prevent the column from injuring the hands of
the person manipulating the chain.
3.4 Slip the chain around the sprocket so that the end of the chain
reaches approximately half way across the Base Frame.
Place Chocks here

23456789
23456789
23456789

Fig. 7
3.5 Once the chain is connected, remove the chocks, lowe the
column and screw down the column mounting screws again,
leaving them finger tight.
3.6 Proceed to connect the chain to the sprocket in the other column in
a similar manner,ensuring that the run of chain, from one sprocket
to he other, is as tight as you can get it, without turning the sprocket,
(as this will cause the carriages to become missaligned).
3.7 The two ends of the chain can now be brought together and
joined using the quick coupling provided (fig.8).
3.8 Once the chain is in place, it must be adjusted by screwing the
adjuster screws, (fig. 7), clockwise.
Screw in each adjuster, in turn, by a similar amount - say ½ turn
each side, until the gap at the centre, between the two runs of the
chain, is 10mm when using reasonable force of the thumb and
forefinger of one hand only. (see fig.9).
This microswitch is a safety feature, and operates when the
chain becomes too slack (less than 10mm gap at the centre of
the run), or breaks, shutting off the power to the motor.
3.9 Finally, connect the two electric cables, one from the base of
each Column, to the leads from the microswitch, using the two
waterproof in-line connectors packed in the parts bag.
Trim the cables back so that there is as little slack in the cable as
possible, to prevent any possibility of the connector, or the
cable, coming into contact with the chain.

Connect brown to brown, and blue to blue. When adjustments are completed, apply chain lubricant
to the chain (not supplied).
5. The Arms
The long telescopic arms must be
mounted on the FRONT of each Arm
Carriage, i.e. at the side of the column
facing the longer foot.
Note that the arms are ‘handed’.
Shown in fig. 10 are the four arms
supplied, two Long - Telescopic, and
two Short - Hinged.
The right hand long telescopic arm is
located on the front carriage mounting
of the right hand (driven) column.
The right hand Short Hinged Arm is connected
to the rear carriage mounting of the right
hand (driven) column. etc.
Insert the end of the arm into its housing in the
carriage, line up the holes and insert the 40mm
dia. pin (item 3, fig.11) with the ring nut (2), at
the top. Secure from below with the circlip (4),
provided.
A
Fig. 10
Fig. 11
NOTE:
1. If the arms are low down, making it difficult to fit the circlips (4), wait until the arms are raised,
during testing, when they can be fitted with ease.
2. It is recommended that you apply a thin layer of grease to the pins before insertionand also on
to the carriage sliding guides when assembly of the arms is completed.
6. The Arm Safety Bars (Ref Fig 11)
The Arm Safety Bars (item 17), lock the arms in a set position preventing them from swinging freely,
and also limits movement, so that they do not collide with each other.
This allows them to be safely locked out of the way when
required, and provides for easy and quick lining up of
the arms and pads with the lifting points without the
possibility of the arms moving whilst unattended. i.e.
when operating the lift to take the weight of a vehicle.
The threaded Safety Bar has a boss welded to one end.
This fits on to a pivot pin on the carriage. It can fit either
way round. Ensure the pivot pin and the hole in the boss,
are free of paint or preservative, and apply a drop of oil
to the pin before fitting the safety bar, ensuring it is fully
seated on the pin.
Do not fit the circlip to the top of the pin at this stage.
Fig. 12
Fig. 13
Insert the Spring (19), into the Housing (A),in the arm followed by the Safety nut
(18). Ensure the threaded portion of the hole in the safety nut is at the bottom as
shown in fig. 13.
Push down on the safety nut, against spring pressure, and ensuring the hole in
the nut lines up with that in the housing, swing the arm so that the safety bar (17)
threads its way through the housing and nut.
10
Release pressure on the safety nut and the spring will push the nut upwards, locking its threads with
those on the bar, thereby locking the bar in place.
To test its operation, press down on the safety nut and the threads should disengage, allowing the
arm to move freely. If it proves to be difficult to disengage the threads by pushing down on the nut,
it will be necessary to reposition the boss of the safety arm, on the pivot pin on the carriage.
If the safety bar is locked, i.e. the threads will not disengage when the safety nut is pressed down,
apply an upward pressure to the safety bar whilst pushing down on the safety nut, thereby
disengaging the threads, then get an assistant to swing the arm in order to withdraw the safety bar
from the safety nut and housing.
Pull the safety bar from the pivot pin,place a flat
washer (provided) on to the pin and replace the
bar. Connect the bar to the safety nut as
previously described and retest to ensure the bar
Flat washer placed
on the pin before the
Safety Bar is refitted
releases correctly when the safety nut is pressed
down.
If necessary, repeat the operation, by placing
another washer on the pin, until the safety bar
locks and releases satisfactorily.
When completely satisfied, fit the circlip (16), to the pivot pin, and screw the self locking nut on to
the end of the safety bar,to its full extent. i.e. ensure the threaded safety bar is completely through
the nut and is gripped by the nuts’ nylon insert.
Fig. 14
7. The Foot Guards
The four Foot Guards are safety devices and must be in place.
They are designed to prevent people from casually standing
on the base of the column, with a foot extended into the Free
Safety Area, thereby inviting the arm carriage or arm, to crush
the foot on its downward travel.
They are located with a single Column mounting bolt as
shown in fig. 14.
8. The Safety Guides
Safety Guides are provided which are bolted, one to each carriage, and can be clearly seen in fig.,
1, mounted immediately above the arms.
Each guide has rubber pads at each end of the guide bar to prevent serious damage to a vehicle
if it is not driven or positioned correctly between the columns. The safety guides also affords some
protection for the columns themselves.
These guides should now be bolted the carriage, in the manner shown in fig. 1.
9. Final Adjustments
The machine is now ready for final adjustment. This involves securing the columns firmly to the base
frame, and bolting the complete assembly to the floor ensuring the columns are perpendicular, and
perfectly in line with each other.
Firstly, screw down the column mounting screws, progressively, to a torque setting of 32lbft (43Nm).
Using a large spirit level, ensure the columns are perpendicular, in both directions, and in line with
each other. Any misalignment may be corrected with shims placed beneath the base frame at
strategic points. Remember, the floor should be properly prepared beforehand, and should be
perfectly level and flat at the area supporting the lift. This will simplify the job of aligning the columns.
All mounting points must be in solid contact with the floor, and any gaps between the base frame
and the floor, must be taken up with suitable shims (‘U’ shaped at the mounting bolts), of at least
80x80mm dimension.
When completely satisfied, tighten the bolts progressively to the torque setting recommended by
the foundation bolt manufacturers.

ELECTRICAL CONNECTIONS
WARNING
1.This machine must be earthed
2.Electrical installation of this machine must be carried out in accordance with all IEE
regulations and must be carried out by a qualified electrician.
1. Model CPL30S
This model is powered by a 230 VAC, 50Hz, Single phase motor,
Connect the mains lead to a 230V 50Hz electrical supply, having a fuse rating of 20amps.
IMPORTANT: A 13Amp plug MUST NOT be used with this machine.
The conductors in the mains lead are coloured in accordance with the following code:
Green & Yellow-Earth
Blue-Neutral
Brown-Live
As the colours of the flexible lead may not correspond with the coloured markings identifying
terminals in your electrical supply, you should proceed as follows:
Connect the Green & Yellow conductor to terminal marked with the letter ‘E’ or Earth
symbol “ ”, or coloured GREEN or YELLOW & GREEN.
Connect the Brown conductor to the terminal marked with the letter ‘L’ or coloured RED
Connect the Blue conductor to the terminal marked with the letter ‘N’ or coloured BLACK
9.2Model CPL30T
This model is powered by a 400 VAC, 50Hz,three phase motor. and connection should be made
through a fused isolator having a delayed fuse rating of 20Amps.
The conductors should be connected as follows:
Connect the Green & Yellow conductor to terminal marked with the letter ‘E’ or Earth
symbol “ ”.
The other conductors should be connected, one to each of the three available phases.
It is IMPORTANT to ensure that the phase connections are correctly made, so that the motor turns
in the correct direction of rotation. i.e. when the UP button is pressed the arms are raised, conversly
when the DOWN button is pressed they are lowered.
If the arms lower when the UP button is pressed, it will be necessary to reverse two of the three phase
connections in order to reverse the direction of rotation of the motor.
When testing the machine, ensure all precautions are taken as previously described.
IMPORTANT:
Connection must be made via a fused isolator, located close to the machine so that it is
easily reached by the operator. We further recommend that a Residual Current Device
(RCD) be used.
NOTE: It may be necessary to replace the mains cable, supplied with the machine, with one of a
more suitable length for your installation. Ensure the conductor sizes are at least the same as those
in the cable supplied.
WARNING
The trailing cable from the machine to the mains supply MUST be protected in accordance
with IEE regulations.
12
THE LUBRICATING PUMP
Each Drive Screw is lubricated by a pump located in the arm carriage. When the arms are at their
lowest level, the pump is charged with oil from the reservoir in the base of the column. As the arms
are raised, oil is delivered to the point of contact between the Drive Screw and Nut. Before the lift
is used therefore, the oil reservoir must be filled with oil as follows:
Remove the side panel (3) from each column and pour 1 litre of oil (Shell Spirex Heavy Duty 85W/
140 or equivalent is recommended) into the base of the column.
Observing all precautions previously mentioned, and keeping hands etc. well clear of the moving
parts, switch on the power to the machine, and turn the main ON/OFF switch to ‘I’ (ON).
Press the ‘
the ‘ ’ (DOWN) button and lowering again. Repeat this operation a few times, until the pump
delivers oil to the nut during the UP phase.
When satisfied, switch OFF the machine at the main ON/OFF switch, and the mains supply, with the
arms in their lowest position, then replace the side panels.
’ (UP) button and allow the machine to rise by 20 - 30cm, before releasing and pressing
CONTROLS
Due to the care in which the machine is designed and manufactured, there are no special
commissioning tests to carry out, however, once the machine has been installed, fully check its
operation without a load. Should it not raise or lower to its fullest extent, check to ensure the limit
switches in the drive column, and one in the driven column, are correctly set to allow maximum
movement of the arm carriages.
The diagram shows the Control Panel, which is
located at the rear of the left hand (driving)
column.
If desired the main ON/OFF switch can be
padlocked in place, and this is strongly
recommended whenever the lift is left
unnattended.
NOTE: The provision of the ON/OFF safety switch
does not preclude the user from providing a
mains supply isolator, in accordance with IEE
regulations.
OPERATION
Ensure the main ON/OFF switch is in the ‘O’(OFF)
position, then swing the arms well clear so that the
vehicle may be driven in line with the axis of the lift,
and centralised between the two columns.
It is extremely important to ensure the vehicle is
positioned so as to achieve correct load
distribution on the arms .
Fig. 15 illustrates the manner in which a typical
vehicle should be positioned.
Fig. 15
Always check as to whether the vehicle is carrying
an abnormal load. i.e in the boot, or in the back of
a van etc., and have it removed before
positioning. DO NOT exceed the max. capacity for
the lift.
13
MAX
2500kg
Position the arms so that the rubber pads are directly beneath
the lifting points recommended by the vehicles’ manufacturer,
then screw out the pads so that they are in solid contact.
Screw out the coarser, large diameter screws first, from below
the Arm, until the pad is almost touching the lifting point. Then
bring the pad lightly into contact by screwing out the pad itself.
It may be necessary at this stage to adjust the position of the Arm
slightly in order to ensure the pad is correctly aligned before
finally bringing it firmly into contact by screwing out the large
diameter screw again.
Ensure all precautions are taken as previously described
before turning the main ON/OFF switch to ‘I’ (ON), and
pressing the (UP) button briefly in order to take the
weight of the vehicle ONLY. DO NOT attempt to lift the
vehicle in one operation.
Only when the full weight of the vehicle is taken and the
vehicle is deemed to be level and stable should you
continue to raise to the desired operating height.
Once the lift is at the desired operating height, DO NOT
FORGET to turn the main ON/OFF switch to the ‘O’ (OFF) position.
When lowering the lift, first ensure that all personnel,tools and equipment are removed from the safety
area and vehicle before turning the main ON/OFF switch to ‘I’ (ON) and pressing the (down) button.

MAINTENANCE
IMPORTANT:Unless the maintenance task requires that the machine be operated,ensure it
is switched OFF at the main ON/OFF switch, and the mains supply, before commencing.
Weekly
Clean the machine at least once per week, removing all foreign bodies and dirty materials. Use a
suitable non-corrosive, oil free detergent where necessary. DO NOT use water or inflammable
liquids. The Support Pads must be free from oil or grease at all times.
Monthly
1. Check the drive nut wear by raising the arms
until the drive nut is in line with the spy hole in
the columns’ side panel (remove the plastic
bung).
The drive nut is shown in fig 18. Check the
distance between the drive nut, and the
safety nut as shown.
If this distance appears to be less than 10mm,
remove side panel and measure. You should
seek technical assistance from your Clarke
dealer, if the measurement is less than 10mm,
as it may be necessary to replace the drive
nut.
2. Check the operation of the Screw Lubricating
Pump, by raising the arms and observing the

Oil should be seen moving through the plastic lubricating tube to the drive nut.
If there is no oil present, or if only air bubbles can be seen, remove the side cover and add
oil (Shell Spirex Heavy Duty 85W140 or equivalent is recommended), before re-checking the
pumps’ operation.
3. Remove the base frame Cover Plate to allow access to the chain, and lubricate it with
chain lubricant.
4. Lubricate the upper screw bearings which are accessed from the top of each column.
Apply a few drops of oil to each bearing.
5. Grease the Sliding Carriage Guides. Clean off any excess.
Annually
1. Remove columns’ side panel, pump out the oil from the base of the column. Clean
thoroughly and refill with clean oil (Shell Spirex Heavy Duty 85W140 or equivalent is
recommended).
2. Check for lateral movement of the carriage on its guides. Any movement can be taken up
by adjusting the guide rollers, which are accessed by removing the side panels, and can be
found at each side of the carriage.
Undo the locknuts and screw out the nylon guide rollerss until any wear is taken up. If the
guide rollers are badly worn, contact your Clarke dealer for advice.
3. Check motor Drive Belt tension. The drive belts are located at the top of the drive column.
Belt tension is correct when the belt can be depressed by 12mm (½”) at the middle of its
longest run, using reasonable thumb pressure.
Adjustment is effected by slackening the motor mounting bolts, jacking out the motor to give
the required belt tension, and re-tightening the mounting bolts.
