HYDRAULIC OIL & FILTER
• Check hydraulic oil daily, with engine off and
cool, and replenish as necessary. A site glass is
provided for easy viewing. If oil can be seen in
glass, there is enough oil in the tank. Do not fill
the tank more than 7/8 full; operating at high
temperature will cause oil to expand and spill over
if tank is full. Tank capacity is 9 gallons.
Remember to replace and tighten cap.
• The machine is equipped with Citgo AW32
hydraulic oil at time of manufacture; use same or
equivalent.
• Drain and replace hydraulic oil at least once a year,
more often if oil is very dark or smells burnt.
Discard used oil properly.
• 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.
