SAFETY PRECAUTIONS
THE LIFTING TABLE
1. The table must be maintained and repaired in accordance with the these
instructions. Such maintenance and repair must be carried out by qualified
persons and tested prior to returning to service.
2. Ensure that the lift table is in good working order. Have any damaged parts
repaired or replaced immediately. Use genuine Clarke parts only. The use
of unauthorised parts may be dangerous and will invalidate the
guarantee.
3. Do not exceed the maximum safe working load of the table stated in the
Technical Specification on page 2. Always ensure the load is evenly
distributed across the table.
4. Never tamper with the lifting table or modify it in any way, as this could
prove to be dangerous and will invalidate the guarantee. Only use the
product for the purpose for which it is intended.
5. Do not use if an oil leak is apparent. Consult your Clarke dealer.
6. Check the condition of the labels regularly and replace as required. Labels
are provided in accordance with BSEN1570.
THE WORKPLACE
1. Only use in a suitable, well lit work area.
2. Keep the work area clean and tidy and free from unrelated items.
3. Use the lifting table on level and solid ground, preferably concrete. Avoid
soft/unmade ground as the wheels may sink in. Excessive force may be
invited to move the table if floor conditions are poor.
4. Use appropriate safety equipment, such as protective footwear, when
using this product.
DURING OPERATION
1. Never climb on, or attempt to ride on the lifting table.
2. Never use the lifting table for lifting, lowering or transporting persons.
3. Never transport a load in the raised position.
WARNING: THE USER MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS
INSTRUCTION MANUAL AND NOT OPERATE THE LIFTING TABLE UNTIL
HAVING DONE SO.

4
4. Never alow hands or feet to be placed under the platform within the
range of movement of the scissor lift components. Take care not to trap
fingers in the moving parts.
5. Always ensure when lifting, that all parts of the load can be clearly seen.
6. Always ensure the load is centralised on the table and is completely stable
before lifting or moving. DO NOT secure by hand alone, use securing straps
where necessary.
7. Always apply the brakes before lifting or lowering, when the lift is left
unattended, or when stationary on an incline.
8. Always ensure the lift table is left in its FULLY LOWERED position when not in
use.
9. Take all necessary precautions when handling heavy equipment. Be
aware that moving equipment of 300 or 500 kgs can be hazardous. The
load MUST be adequately secured when the table is moved.
10. Be aware that force may be required to move a load of 300 or 500 kg. Take
all safety precautions when moving and stopping to ensure it is carried out
under complete control.
11. Be aware of what is happening in the immediate vicinity, and anticipate
possible hazards...blind corners, overhead obstructions etc. Take great
care when lowering a load, that the hands are not trapped by the load.

BEFORE USE
UNPACKING
Obtain the assistance of a second person when unpacking the lifting table
from its packaging. Alternatively, cut and fold down one end of the box and
wheel the lifting table out.
ASSEMBLY
Lower the handle into the holes in the frame and secure each side from below
with the bolt (64), spring, and flat washers (63 & 62), provided.
Insert the foot operating lever (59) into its socket at the end of the connecting
bar (60). Insert the bolt (42) and secure with washers (6 & 11) and nut (12).
PURGING AIR BUBBLES
During shipment, air bubbles can occur in the hydraulic system which may
cause the ram to feel “spongy” and it may not achieve its maximum lift.
1. Hold the release lever and pump the operating lever several times to
purge any air from the hydraulic system.
2. Pump the operating lever to raise the table fully, then pull the release lever
to lower the table and check that it descends to its lowest position.
The lifting table is now ready to use.

6
OPERATION
Before raising or lowering the table:
1. Check for any damage or worn parts. Do not use the lifting table unless it is
perfectly serviceable.
2. Lock the castor brakes before loading the table. (A brake is provided on
each castor for safety).
3. Ensure the load is completely stable and evenly spread on the table and
secured if necessary.
4. Ensure that no obstacles can snag or prevent the table from being raised.
RAISING A LOAD
1. Pump the foot lever (59) until the table reaches the desired height. (The
release lever (65) is spring loaded to return it to its closed position).
SAFETY BARS (‘A’ FIG.1)
IMPORTANT: When working with
the table raised, the safety support
bars must be put in place and the
table lowered so that the load is
supported by the safety bars and
not by the hydraulic ram, as
shown in the illustration. The safety
bars are secured with a clip, one
to each leg of the lift.
2. Make one final check to ensure
that there are no obstructions
to lifting and that all personnel are well clear before continuing to pump
the handle and lift the load.
LOWERING THE LOAD
1. Slowly pull the release lever (65) upwards. Ensure the load is lowered in a
fully controlled manner - do not jerk the lever upwards.
• Releasing the lever will cause the table to stop at any desirable
height.
WARNING: BEFORE LIFTING, ENSURE THE SAFETY PRECAUTIONS ARE
STRICTLY FOLLOWED. NO RESPONSIBILITY CAN BE ACCEPTED FOR
INCORRECT USE OF THE TABLE.

7
NOTE: This operation must be done very slowly and in full control. DO
NOT let the load lower suddenly, this could damage internal
components.
NOTE: Take care to ensure when lowering, that the safety bars do not
foul the bolt heads shown at B.
MAINTENANCE
DAILY/BEFORE USE
Inspect the lift table for signs of obvious damage, distortion of components,
damage to castors etc.
Check the ram for signs of hydraulic oil leakage.
If any of the above are apparent - DO NOT use the table lift. Have it inspected
by a qualified person and repaired if necessary.
NOTE: Be aware that oil leaks can produce extremely hazardous
environmental conditions. All leaks must be cleaned
immediately and sand/sawdust or similar absorbent material
should cover the contaminated area (which should be isolated),
until it is completely cleaned and dried.
MONTHLY
1. Check that all joints and pivots are clean and moving freely. Lubricate all
pivots with light oil.
2. Check the action of the hydraulic ram and inspect for leaks. If leaks are
apparent, DO NOT USE THE LIFTING TABLE, but submit for repair. (Contact
your Clarke dealer). Always make every effort to contain any escape of oil
and prevent ingress into the local water course.
3. The hydraulic system may be topped up with any commonly available
hydraulic oil such as Clarke hydraulic oil (part number 3050830).
4. Check castor brake action and ensure that the table lift is held securely
when they are applied.
5. Remove any corrosion and repaint for protection.
6. Check the piston rod periodically for signs of corrosion. Clean exposed
areas with a clean oiled cloth.
7. Ensure that labels and warning notices are in place and legible.
8. Inspect for distortion of hinge pins and security of all nuts and bolts.
9. Keep all moving parts lightly lubricated to prevent corrosion.

8
10. In the case of a persistent oil leak which requires the dismantling of the
hydraulic parts to correct, the lift table should be taken to your Clarke
dealer for overhaul.
NOTE: ALL major repairs MUST be re-tested according to BSEN1570:-
ANNEX C regulations and should therefore be carried out by your
CLARKE dealer.
TROUBLESHOOTING
If any of these remedies fail to restore your lift table, consult your Clarke dealer
STORAGE
Store in a dry place with the ram fully lowered to minimise ram and piston
corrosion. If stored for long periods, inspect at least once a year, clean and re-
oil. For servicing, contact your CLARKE dealer, or CLARKE International Service
Department.

Platform rises then sinks 1. Non-return valves (23,
24, 16), not seated
correctly
2. As (2) above
1. Clean valve holes and
