Filtering Closed−Loop Traction Circuit (continued)
Hydraulic System: Service and Repairs
While engaging the traction circuit, monitor the indicator on the high
flow hydraulic filter. If the indicator should show red, either reduce
pressure on the traction pedal or reduce engine speed to decrease
hydraulic flow through the filter.
7. With engine running at low idle speed, slowly move the traction pedal to the
forward direction to allow flow through the traction circuit and high flow filter.
Keep traction circuit engaged in forward for five (5) minutes while gradually
increasing both forward pressure on traction pedal and engine speed until
engine is running at 2000 RPM. Monitor filter indicator to make sure that
green color is showing during operation.
If using a filter that is not the Toro high flow filter that is bi−directional,
do not press the traction pedal in the reverse direction. If flow is
reversed when using a filter that is not bi−directional, debris from
the filter will re−enter the traction circuit.
8. With engine running at 2000 RPM, alternately move traction pedal from
forward to reverse. While monitoring filter indicator, continue this process for
an additional five (5) minutes.
9. Shut engine off and remove key from key switch.
10. Remove high flow hydraulic filter and hydraulic hose kit from machine.
Connect hydraulic hose to hydraulic tube. Make sure to properly tighten hose
(see Installing Hydraulic Hoses and Tubes (O-Ring Face Seal) (page
11. Lower machine to ground.
12. Check oil level in hydraulic reservoir and add correct oil if necessary.
