SERVICE INSTRUCTIONS
CLEANING THE OIL COOLER CORE EXTERIOR
If the air flow through the oil cooler becomes restricted the hydraulic oil may begin to operate at too high
a temperature which will shorten the life of the hydraulic pump. Clean the oil cooler daily to prevent the
buildup and hardening of concrete dust. If the oil cooler becomes blocked due to lack of cleaning it will
eventually need to be replaced. Clean the radiator with compressed air or use a pressure washer
before dusty material hardens to the radiator.
CHECKING OIL COOLER HOSES
Periodically check all hoses of the cooling system for leaks or deterioration. Replace any questionable-
appearing hoses with new ones.
CHECKING HYDRAULIC OIL LEVEL
The hydraulic oil level is checked by looking at the transparent hydraulic tank. Compare the oil level to
the “full” line located on the front of the hydraulic tank. Check the oil level with the machine parked on
level ground, the oil at normal operating temperature. Add oil as required to maintain correct oil level.
HYDRAULIC OIL FILTER ELEMENTS:
Change the hydraulic oil filter on the return line as follows:
With the machine turned off, remove the top of the filter housing and replace filter element. Do not allow
any dirt and debris to enter the hydraulic tank.
Change the hydraulic oil filter on the pressure line as follows:
Unscrew the lower portion of the filter housing, and replace filter element. Do not allow any dirt and
debris to enter the filter housing.
