MAINTENANCE
10. Clean inside the hydraulic tank
with a clean and dry cloth in order to
remove any metal particles or debris
accumulated at the bottom.
• To clean the interior of the an
aluminum tank (cylindrical), insert
the hand in the hole where the
strainer was fixed. This allows to
clean one half of the tank. To clean
the other half, remove the entire
filter at the rear side of the tank,
insert the hand inside, and clean
with the cloth.
• To clean the steel tank (Figure
#|1.16), remove the access panel by
removing the retaining screw. Insert
the hand inside and clean the interior
with the dry and clean cloth.
11. Change the return filter element
(twice a year).
12. Refill the tank until oil reaches
the 3/4 of the oil gauge (Figure #1.20).
Use a high quality oil, that has good
performance in cold weather(if
applicable), such as SHELL TELLUS
T32 or equivalent (See “Lubrication”
section for specifications). The
whole system will require between
50 and 60 gallons.
13. The oil must be clean and free of
any dirt, metallic particles or sand
etc.) The use of a filtering screen is
strongly recommended while filling
the tank with new oil.
14. If the suction line has been
replaced, fill the line until the oil
reaches the pump to avoid cavitation
(see section 3.1 of Troubleshooting).
15. Start the engine and check again.
