EXTREMELY IMPORTANT
Read these safety instructions carefully in addition to the instructions for use, operation and maintenance. Keep this
instructions sheet in an easy to find place as you may need to use it again.
This wheel dolly has been designed for removal of twin and large size wheels.
Any other application, beyond the conditions established for use of this wheel dolly will be considered inappropriate.
Handle the wheel dolly correctly and ensure that all parts are in good condition prior to its use.
Only authorised persons should operate the wheel dolly having read carefully and understood the contents of this
manual. Do not modify the wheel dolly in any way.
Non-compliance with these rules may result in injury or damage to the user, the wheel dolly or the wheels to be
removed.
The manufacturer accepts no responsibility for the improper use of the wheel dolly.
1. SAFETY INSTRUCTIONS
1.1. The wheels to be removed should never exceed the rated capacity of the wheel dolly .
1.2. The maximum stroke of the wheel dolly indicated on the label should never be exceeded.
1.3. The wheel dolly should be supported on a solid, level and horizontal surface which is well illuminated and free of
obstructions. Never stand the wheel dolly on a surface which may sink.
1.4. Ensure that the engine of the vehicle is switched off and there are no persons inside the vehicle . Ensure the vehicle
against any type of sliding, apply the brake and use chocks if appropriate . Secure the lifted vehicle with mechanical
stands (B) .Do not enter the vehicle or start the engine during the operation.
1.5. Never position any part of your body under the wheels or the vehicle. Never position any part of your body , (hands,
feet) near the movable elements of the wheel dolly ( C).
1.6. During raising and lowering of the load, all precautions should be taken to avoid movement of the vehicle or the
vehicle load. Traffic may cause the raised vehicle to rock during roadside use of the wheel dolly.
1.7. As an additional safety measure against overload, the jack is fitted with an overload valve set at the factory and
which should not be adjusted under any circumstances. If nominal capacity of the wheel dolly is exceeded the overload
valve will stop the lifting operation.
2. USE AND OPERATION
2.1. Unpack the wheel dolly and check that there are no components missing. Then proceed to the assembly following
carefully the instructions provided .
2.2. Once the wheel dolly is fully assembled and before operating the jack it is necessary to purge air from the valve
system. This is carried out by pressing down on the release pedal whilst pumping the jack with the lifting pedal or hand
lever. This will not only facilitate the elimination of air but the internal lubrication.The wheel dolly is now ready to be
used.
Important.
Prior to removing the wheels ensure that all aforementioned safety instructions are followed.
2.3. The wheels and rollers of the wheel dolly should always rotate freely.
2.4. The hydraulic unit is fitted with a foot pedal that gives a faster approach to the wheels and a faster lifting when the
wheels weight is not too heavy.
2.5. Once the wheel is resting on the lifting arms use the chain to ensure safe movement of the wheel .
2.6. The manual handle reduces the lifting strain when working at maximum capacity.
2.7. Lower the load to the lowest possible point for a safe transport of the wheels .The hydraulic unit is fitted with f a
safety device (LCS) that functions automatically and offers smooth and uniform lowering.
3. MAINTENANCE
Important:
Both the maintenance and repair of the wheel dolly may only be performed by qualified persons, who
have sufficient knowledge of the hydraulic systems used in these devices as a result of their training and experience.
3.1. Keep the wheel dolly clean and lubricate all moving parts at regular intervals (D) , which must be clean and protected
from aggressive conditions at all times.
3.2. Only original spare parts should be used.
3.3. Prior to each use, check for bent, broken, cracked or loose parts and solve the problem, if appropriate. If it is
suspected that the wheel dolly has been subjected to abnormal loads or has suffered any knocks, withdraw it from
service until the problem has been rectified.
3.4. If the oil level needs to be checked or refilled disassemble the hydraulic unit from chassis by removing the screws
and with the piston fully retracted, remove the filler plug and drain its contents into a container. With the hydraulic unit
in a horizontal position, proceed to introduce the necessary oil volume as indicated in these instructions. Make sure
that no dirt enters with the new oil.
Assemble again the hydraulic unit by fixing the screws.
Important:
An excess of oil may render the jack inoperative. Never use brake fluid.
Use only hydraulic oil, type HL or HM, with an ISO grade of cinematic viscosity of 30 cST at 40º, or an Engler viscosity
of 3 at 50ºC.
Following a period of prolonged intensive use, it is recommendable to change the oil in order to extend the useful life
of the wheel dolly..
3.5. When the jack is not in use, make sure the lifting arm is fully retracted to avoid corrosion.
Apply an anti-corrosion product to the pistons, if appropriate.
Keep the wheel dolly in a clean, dry place and out of children reach.
