INTRODUCTION
Please read these safety instructions carefully in addition
to the instructions for use, operation and maintenance and
keep them for future reference.
This jack has been designed for use as an elevator for
transmissions, gearboxes and engines. Any other
application, outside the terms established for its usage, will
be considered incorrect.
Handle this jack properly and before using it check that all
its parts and components are in good state and nothing
is missing.
It should only be used by authorised people, after having
carefully read and understood the contents of this manual.
Do not modify this jack in any way.
Non-compliance with these instructions may result in injury
or harm to the user, the jack or the vehicle being elevated.
The manufacturer will accept no responsibility for misuse
of the jack.
1 SAFETY INSTRUCTIONS
1.1 Secure the element to be elevated so it cannot slide
in any direction.
1.2 The jack should be placed on a firm, regular and
horizontal surface. Never used the jack on a slope.
1.3 The centre of gravity of the load must be located within
the elevation support.
1.4 This jack is not a device for transport, but if it is
necessary to move the load, secure it to avoid the jack
overturning.
Never exceed the nominal weigh limit of the jack.
1.5 The travel of the cylinder, as indicated on the label,
should never be exceeded. This can be seen on the piston
shaft in the form of a red mark.
1.6 As a safety precaution, the pump has an overpressure
valve No. 3, that has been factory-set at the maximum
working pressure and must not be manipulated under any
circumstances.
1.7 Non-compliance with these safety instructions may
result in injury or harm to the user, the jack or the component
being manipulated.
2 USE AND OPERATION
2.1 Before using the equipment it is necessary to bleed
the hydraulic circuit to eliminate air from the valve system.
To do this, open the discharge tap No. 2 and press lever
No. 5 several times. Then close the discharge tap. The
equipment is now ready to use.
To lower the jack, turn the discharge tap slowly with the
lever anticlockwise.
2.2 When you have finished using the equipment, keep it
stored with the cylinder and pump shafts totally retracted.
3. MAINTENANCE
Important.
Maintenance and repair of this equipment must
only be carried out by qualified personnel, who due to their
training and experience, are familiarised with the hydraulic
systems used in this type of equipment.
3.1. Regularly lubricate the shafts and moving parts of the
jack, which should always be clean and protected from
aggressive environments.
3.2. Only use original spare parts.
3.3. Before each use, check that no elements are bent,
broken, cracked or loose and rectify any possible problem
before using. Do not use the jack if you suspect that it has
been subject to abnormal loads or has suffered strong
impact, until the problem has been remedied.
3.4. If it is necessary to check the oil level or top it up, with
the piston totally retracted, remove the oil filler cap and
empty its contents into a container. Then fill it with the
amount specified in these. Make sure no dirt or foreign
objects enter the system while filling with new oil.
After a long and intensive period of usage, it is recommended
to change the oil so as to prolong the service life of the
jack.
Important.
Filling with an excessive amount of oil may stop
the jack from working correctly.
3.5. Use hydraulic oil type HL or HM, with an ISO kinematic
viscosity degree of 30 cST at 40º, or Engler viscosity of 3
at 50ºC.
Very important:
Never use brake fluid.
3.6. When the jack is not in use, the elevator arm should
be totally retracted to minimise piston shaft rusting. We
recommend the application of an antioxidant product on
both the main piston shaft and that of the pump.
3.7. Keep the jack in a dry place.
3.8. When its service life is over, remove the oil and hand
it over to an authorised disposal service, in accordance
with local regulations.
3.9. Both the spare part kit, which only contains the oil seals
and gaskets, and the component spare parts should be
ordered using the reference codes assigned on the table.
