SP8018 TRX SERVICING HYDRAULICS
46
• Replace hydraulic filter every three to
four months of normal use. More often
if used under severe conditions. Use a
10-micron filter, available at most
locations.
• Unscrew old filter and discard properly.
Clean filter housing and install new
filter, making sure old O-ring has been
removed and new filter has a new O-ring
in place. Screw in new filter hand tight
only. Recheck oil level and refill if
needed, as described above.
HYDRAULIC OIL COOLER
(only on remote control machines)
• There is a hydraulic oil cooler on all
remote control machines to keep the
hydraulic oil from over heating. There is
a temp sensor in the bottom of the oil
cooler and if the oil temperature rises to
140° or higher the fan comes on to cool
the oil. The fan may go on and off as the
temperature of the oil changes
depending on the environment and the
operation of the grinder.
• Keep the fins clean. Use a garden hose
and a mild detergent. Do not use a
power washer as it may cause the fins to
bend. Do not use an industrial strength
detergent that may cause the metal to
deteriorate.
• Inspect all connections and hoses for
leaks and wear. Replace if necessary.
Use extra care when inspecting hoses
with fluid under pressure. DO NOT use
your finger or hand to inspect for leaks,
use a board or cardboard. Follow all
safety procedures at the beginning of the
Servicing Hydraulics section.
