  6.  Check the condition of the labels regularly and replace as required. ****

WORKPLACE

  1.  Use the jack in a suitable, well lit work area.
  2.  Keep the work area clean and tidy and free from unrelated items.
  3.  Keep all non-essential persons at a safe distance whilst the jack is in use.
  4.  Use the jack on level and solid ground, preferably concrete. Avoid soft/unmade ground as the jack may sink in.
  5.  Use appropriate safety equipment, such as protective footwear, when using this jack.

OPERATION

  1.  Ensure the vehicle is securely supported.
  2.  Ensure there are no personnel or obstructions under the vehicle before lowering.
  3.  Ensure when lifting, that the jack and all parts of the load can be clearly seen. Always watch the jack and the load during operation.
  4.  Never climb on, or attempt to ride on the jack.
  5.  Take care not to trap fingers in the moving parts of the jack.
  6.  Ensure that you can see the contact and jacking point throughout the jacking operation in case there is any relative movement.
  7.  This jack is for lifting only, do not move a load using the jack as a dolly.
  8.  Make sure the load is taken by the full surface of the cylinder or nose, and that the point of lift on the load is strong enough to support the load adequately.
  9.  Consult the vehicle handbook to determine the correct lifting points.
  10.  Do not work under the raised vehicle until it is supported by suitable means e. g. axle stands, NEVER rely on the jack to support the vehicle by itself.
  11.  Never push a load off the jack.

LIFTING OPERATIONS AND LIFTING EQUIPMENT REGULATIONS 1998

This jack, depending on use, may fall within the scope of LOLER. It is the owner’s responsibility to determine whether or not it does, and if so, to comply with any applicable requirements. It may be necessary to have the jack regularly inspected.

ENVIRONMENTAL PROTECTION

  •  Take care to ensure that any spilt hydraulic oil is cleaned away using sand, or treated with absorbent granules designed for the purpose.
  •  Always make every effort to contain any spillage and prevent ingress into the local water course.

BEFORE USE

FIT THE HANDLE

  1.  Insert the lower handle into the handle socket and tighten the locking bolt shown to secure the handle in position.
  2.  Add the upper handle section and secure with the bolt shown.

CHECK THE OIL LEVEL

  •  Remove the filler plug and check the oil level.
    •  Oil should be up to the edge of the filler hole.
  •  Top up if necessary with Clarke hydraulic oil available from your local Clarke dealer (part number 3050830).
    •  Oil grade SAE10, capacity 480ml.

PURGE AIR BUBBLES

During shipment, air bubbles can occur in the hydraulic system which will cause the jack to feel “spongy” and it may not achieve its maximum lift.

  •  Pump the operating handle several times to purge any air from the hydraulic system.
  •  Twist the handle counterclockwise to open the release valve and lower the jack. Check that the jack descends to its lowest position.
    •  The jack is now ready to use.

OPERATION

RAISING A LOAD

WARNING: BEFORE LIFTING, ENSURE THE SAFETY PRECAUTIONS ARE STRICTLY FOLLOWED. NO RESPONSIBILITY CAN BE ACCEPTED FOR INCORRECT USE OF THE JACK.

WARNING: PLEASE NOTE THAT THE SCISSOR ACTION OF THE JACK WILL CAUSE THE JACK TO MOVE SLIGHTLY AS IT IS RAISED AND LOWERED. IT IS MOST IMPORTANT THAT THIS MOVEMENT IS NOT RESTRICTED IN ANY WAY. ENSURE THE GROUND IN THE IMMEDIATE VICINITY OF THE JACK IS FREE FROM DEBRIS.

  1.  Before use, check for any damage or worn parts. Do not use the jack unless it is perfectly serviceable.

  2.  Ensure the load is chocked and stable, and on firm level ground, before manoeuvring the jack so that the grooves in the nose or the top of the cylinder, (whichever is to be used), is directly beneath the lifting point of the load.

  3.  Twist the handle clockwise to close the release valve.

  4.  Put the nose directly below the lifting point of the vehicle (see the manufacturers handbook for the best locations).

  5.  Make sure that there is no obstruction that will prevent a clear lift
    and that all personnel are in a safe position before you lift the
    vehicle.

  6.  Pump the handle to raise the jack until contact is made with the lifting point.

  7.  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.

  8.  NEVER allow any individual to get beneath the load until it is firmly chocked or supported on axle stands or similar upports.

LOWERING THE LOAD

  1.  With the axle stands/supports removed, check to ensure that there are no personnel in the immediate vicinity before VERY SLOWLY twisting the lifting handle anticlockwise and allowing the jack to lower the load.
    NOTE: This operation must be done very slowly and in full control. DO NOT let the load lower suddenly, this could damage internal components.

  2.  Remove the jack from below the vehicle.
    NOTE: The jack can move slightly during operation. It is important that the area is clean and free from all debris.

MAINTENANCE

  1.  Remove any corrosion and repaint for protection.
  2.  Check the piston rod periodically for signs of corrosion. Clean exposed areas with a clean oiled cloth.
  3.  Ensure that labels and warning notices are in place and legible.
  4.  Inspect for distortion of hinge pins and security of all nuts and bolts.
  5.  Keep all moving parts lightly lubricated to prevent any possibility of corrosion.
  6.  A grease nipple is provided for occasional lubrication of the main supporting axle.
  7.  If an oil leak is seen, check the oil level as described on page 5.
  8.  In the case of a persistent oil leak which requires the dismantling of the hydraulic parts to correct, the jack should be taken to your Clarke dealer for overhaul.

STORAGE

Store in a dry place with the ram fully lowered and the release valve closed. 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.
