Maintenance
During maintenance and inspection operations always follow the safety instructions in this manual. Mechanical
breakdowns caused by inadequate or improper maintenance can lead to high repair costs as well as
work stoppages; therefore, regular and adequate maintenance is indispensable. The safety and life of the
machine depend on many factors, including proper maintenance. Because different companies have different
shift schedules, it is impossible to prescribe in advance how often you should proceed with inspections,
maintenance or replacement. Adjust your inspection routine to the number of work groups you have in
your company. Our local dealer will be delighted to give you further information. The table below contains
information about maintenance and inspection (control intervals, critical points, etc.) for a machine under
normal use.
MAINTENANCE AND INSPECTION SCHEDULES
After reading the following, consult the MAINTENANCE AND INSPECTION TIPS section for more details.
Control interval
Critical points / Maintenance information
Daily
Check green lid gasket and replace it if necessary.
Check the two black piston gaskets and replace them if necessary.
Check the air holes located at the base of the barrel and clear them of any
obstruction.
Monthly
Check the lid closure and tighten if necessary by regulating the lid fixing
bolts (P models only).
Yearly
Check hydraulic oil level and refill the reservoir if necessary.
Every 2500-5000 service hours Change hydraulic oil.
Check oil filter and replace it if necessary.
MAINTENANCE AND INSPECTION TIPS
Green lid gasket:
Replace if damaged or if leaks are observed. This gasket is reversible, i.e. it can be used
with either side facing up. A spare gasket comes with the machine. The gasket is made from a non-toxic
material that is safe for alimentary use. Place the glued joint of the gasket under the lid bolt. To reduce lid
friction and extend lid gasket life, before closing always grease the green gasket and the lower part of the lid
with animal fat or another USDA approved.
Black piston gasket:
Replace if damaged or if leaks are observed. To reduce noise caused by the movement
of the piston, grease this gasket with animal fat or another USDA approved shortening before placing it in the
barrel.
Hydraulic oil level:
The oil level can be tested with the dipstick provided on the oil inlet screw. Always fill the
reservoir to the maximum level marked 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.
Hydraulic oil duration:
The life of hydraulic oil varies depending on many factors, e.g. temperature and
