NOTE: If the machine is new or if a major
component has been overhauled or replaced in the
hydraulic system, replace the pilot filter and return
filter after 50 hours of operation. After that, replace
these filters at the stipulated interval.
IMPORTANT: Every 1000 operating hours, it is
necessary to have the hydraulic fluid analyzed. See
your Dealer.
IMPORTANT: After replacing the hydraulic fluid, it is
necessary to bleed all air from the hydraulic
components. See Bleeding air from the hydraulic
components.
IMPORTANT: If metal filings are discovered in the
replaced filters, see your Dealer.
WARNING: Before carrying out any service
work on the hydraulic system it is necessary
to allow it to cool down (the temperature
should not be more than 40°C (104° F).
WARNING: Hydraulic fluid or grease
injected into your skin can cause severe
injury or death. Keep your hands and body
away from any pressurized leak. Use
cardboard or paper to check for a leak. If fluid
is injected into your skin, see a doctor
immediately and have the fluid removed.
WARNING: Before carrying out any
operation on the hydraulic filters or the
hydraulic system, the pressure must be
released from the system. Failure to observe
this instruction can cause injury. See
Releasing pressure in the hydraulic system.
