Installation
CONNECTING THE MACHINE
Make sure the electrical characteristics of the machine (connection, voltage, and frequency) are suited to your
power source. (These specifications are given in detail on the technical specifications sticker affixed to the
machine itself; there is a tolerance of ±10% for voltage and of ±2% for frequency). If the specifications are
compatible with your power source, refer to the OPERATING INSTRUCTIONS section below. If the electrical
features of the machine are not compatible with your power source and your machine is a dual voltage, three-
phase unit, adjust the voltage as described below in the CHANGING VOLTAGE section. Once the machine has
been installed and the oil level inside the reservoir has been checked using the dipstick attached to the oil inlet
screw, check the turning direction of the three-phase motor. If the phases are correctly adjusted, the piston will
rise and fall when the knee pedal is pushed. If the phases are incorrect, the pump will not work properly; the
motor will make noise, but the piston will not move. Stop immediately and interchange two of the three phases
in the plug. Make sure that the plug and outlet are appropriate for the machine.
IMPORTANT:
the wiring in the electrical cord is normally assigned as follows: Phase(s): • Black, Brown,
Gray • Ground wire: Two-colored Yellow/Green or Green. Check the wiring before connecting; call a qualified
electrician if the electrical specifications do not correspond with your power source.
HYDRAULIC OIL FILLING
The H filler/stuffer is delivered with hydraulic oil already in the internal reservoir; therefore, the initial addition of
oil to the hydraulic system is usually unnecessary. In the exceptional case that a machine is delivered without
hydraulic oil in the reservoir, do not turn it on. Fill the reservoir as follows:
•
Remove the oil reservoir screw (marked OIL) located in the upper part of the base.
•
Check that the correct level of oil is inside the reservoir by using the dipstick (with max./min. marks)
attached to the oil reservoir cap.
• Using a funnel, pour the hydraulic oil into the tank. Do not fill the reservoir to the top since a certain
amount of air must remain in the reservoir to allow for expansion. Use oils for medium pressure hydraulic
assemblages (approx. 100 bar), and of a viscosity of approximately 5º Engler (equivalent to IS03498: cat
HL VG46 or DIN8659: HL-46). After filling the reservoir, raise and lower the piston several times to purge
any remaining air from the hydraulic circuit.
Always fill the reservoir to the maximum level without exceeding it since the more oil there is in the reservoir,
the more effectively the heat given off by the hydraulic assemblage will be cooled. This helps lengthen the life
of the oil. Because there should be no loss of oil or oil vapors, an adequate level of hydraulic oil should last
several years (between 2500 and 5000 hours of use), making it unnecessary to check the oil level as long as
the machine is functioning well. For more information, see the MAINTENANCE section below.
CHANGING THE VOLTAGE
IMPORTANT:
Only for three-phase machines with dual voltage motor 380/220 Volt (400/230 Volt for EU), etc.
This operation should only be carried out by a qualified electrician. Do not connect the machine to the power
source. If already plugged in, unplug it and leave it disconnected for the entire process. Remove the screws
from the steel lid on the base. Remove the lid.
