the lifting device and the load during all
movements. Immobilize the table during
lifting or lowering operations. If the load
tilts or sways during operation, maintain
a safety distance and do not attempt to
hold it steady.
• Keep the work area well illuminated and
free of unnecessary elements.
• The table is a lifting and lowering device
and therefore it should not be used as a
permanent means of transportation. To
move the load a short distance, keep the
table in its lowest position, check that
the floor is clean and non-slippery, there
is full frontal vision and the table does
not bump into obstacles in its path.
• Non-compliance with these essential
safety instructions may result in injury
or damage to the user, the table or the
element to be lifted.
• As an additional safety measure against
overload, the table is fitted with an
overload valve which has been set at its
maximum work pressure at the factory.
This valve should not be adjusted under
any circumstances.

USE AND OPERATION

1. Introduce the handle into its correct
position according to the illustration
(Figure. 1).
2. Prior to using the table, the hydraulic
circuit needs to be drained in order to
eliminate any air from the valve system.
For this, turn the handle in a lockwise
direction (3), hold it in this position
and pump several times. Then let go
of the handle, which will automatically
return to its initial position (dead man's
principle) and the jack is then ready to
carry out the elevation operation.
3. The load is lifted by pumping the handle
in a downwards movement (2). Check
that there are no obstacles above the
table. To facilitate a quick approach to
the load, our tables are fitted with a
pumping pedal.
4. Prior to lowering the load, check that
6
there are no obstacles or persons under
the platform. The load is lowered by
gradually turning the handle in an anti-
clockwise direction (3). Our tables are
fitted with an automatic adjustment and
control system (L.C.S) to avoid brusque
lowering.
MAINTENANCE
• Both the maintenance and repair of this
table may only be carried out by qualified
and authorized personnel, who as a
result of their training and experience
are familiar with the hydraulic systems
used in these devices.
• Regularly clean and lubricate the axes of
the moving parts of the table (6), which
should be kept clean and protected from
aggressive conditions at all times.
• Only original spare parts should be used.
• Prior to each use, check for bent, broken,
cracked or loose parts and solve the
problem, if appropriate. If it is suspected
that the table has been subjected to
abnormal loads or has suffered any
knocks, withdraw it from service until
the problem has been rectified.
• If the oil level needs to be checked or
refilled, dismantle the hydraulic unit and
with the piston fully retracted, remove
the filler plug and drain its contents
into a container. With the hydraulic
in a horizontal position, proceed to
introduce the necessary volume for each
model as indicated in these instructions.
Avoid the entrance of any dirt with the
new oil.
• Following a period
intensive use, it is recommendable to
change the oil in order to extend the
useful life of the jack.
IMPORTANT: AN EXCESS OF OIL TO THE
VOLUME REQUIRED MAY RENDER THE JACK
INOPERATIVE.
• Only use hydraulic oil, HL or HM type,
with an ISO grade of cinematic viscosity
of 30cSt at 40ºC or of an Engler viscosity
of 3 at 50ºC.
EXTREMELY IMPORTANT: NEVER USE BRAKE
FLUID.
• When the table is not in use, it should
be fully retracted in its lowest position
of prolonged
