5.9 HYD RESERVOIR FLUID 5.10 HYD OIL FILTER
The chippers are tested before shipping. In order to test the
equipment the fluid levels are filled. However, check the fluid
levels before initial operation and add if necessary (see the
assembly section). Always check levels before each use.
To check levels look at the side of the hydraulic oil container
and make sure the fluid level falls between the marks. If
necessary add oil.
On the Kubota models the hydraulic tank is located next to
the fuel tank. A cutout exists to check the fluid level.
Premium hydraulic fluids containing high quality rust,
oxidation and foam inhibitors are required. These include
premium turbine oils, API CD engine oils per SAE J183,
M2C33F or G automatic transmission fluids meeting Allison
C-3 or Caterpillar TO-2, and certain specialty agricultural
tractor fluids.
It is recommended that this filter be changed after the first
50 hours and every 200 hours thereafter. To change:
1. Using an oil filter wrench turn the filter counterclockwise.
2. Once the filter becomes loose, turn it out the rest of the
way with your hand.
3. Properly discard old filter.
4. Lube the rubber seal on the new filter (P/N 16588) with
clean hydraulic oil.
5. Install the filter onto the threaded pipe. Turn with your
hand until the filter is finger tight.
6. Turn, by hand, another 1/2 turn.
7. Check hydraulic oil level and fill if necessary.
1. Check wheel bolt torque every 10 hours of towing use.
2. Check air pressure in tires every 10 hours of towing.
3. Check and repack wheel bearings with grease every 12
months.
4. When towing, always connect the safety chains. Make
sure trailer hitch bolts are tight and secure.
5. Check trailer lights.
