OPERATION
VERY IMPORTANT: Ensure that the table is
firmly resting on the axles. Especially for
presses with a winch.
General oprational description:
• Place the wedge on the press table, then
attach the work piece on the wedge.
• Activate the pump until the piston
approaches the piece.
• Align the piece and the piston so that the
piece is properly centered.
• Activate the pump to apply pressure to the
piece.
• When the work is finished, stop the pump
and open the release valve by stepping on
the pedal as to remove the piece.
• When the work is finished, stop the pump
and open the release valve by stepping on
the pedal so as to remove the piece.
MAINTENANCE
• Lubricate the axes and moving parts at
regular intervals.
• The elements of the press should be kept
clean and protected from aggressive
conditions at all times.
• Always use original spare parts.
• Check the oil level of the pump with the
piston of the cylinder fully retracted and
refill as required in accordance with the
volume indicated in the table. To perform
this operation, you must first release the
lower cover of the press that allows us to
reach the tank. The cover is threaded on its
upper part.
IMPORTANT: An excess of oil may affect
the operation of the hydraulic unit.
• 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.
A frequent inspection should examine:
• Wear on the piston, cylinder, pump,
accessories or incorrect connections.
10
• Oil leaks, signs of corrosion, damage to the
structure, accessories, table and supports,
lost screws or plug-ins.
REPAIR
Both the maintenance and repair of these
presses should be carried out by qualified
personnel, who as a result of their training
and experience are familiar with the hydraulic
systems used.
Both the repair kit, which exclusively contains
the o-rings and seals of the jack, and the
spare parts sets must be orderedusing the
reference assigned in the table.
To purge the hydraulic circuit:
• Open the release valve by stepping on the
pedal.
• As follows, pump the hydraulic unit several
times.
