Brake Maintenance with compressed air. Start from the front and blow the debris out towards the back. Then clean from the back side and blow towards the front. Repeat Adjusting the Service Brakes procedure several times until all chaff and debris is removed Adjust the service brakes when there is more than 1 in.
Change the 2 hydraulic filters initially after the first 200 operating hours. Thereafter, change the filters after every 800 operating hours, in normal conditions. Use Toro replacement filters Part No. 94-2621 for the rear (cutting unit) of the machine and 75-1310 for the front (charge) of the machine.
Hydraulic System Test Ports The test ports are used to test the pressure in the hydraulic circuits. Contact your local Toro distributor for assistance or refer to the Service Manual. Test Port A (Figure 58), located on rear of filter manifold, under right hand frame rail.

Test port G (Decks) Test Port H (Figure 62) located on rear traction circuit hard line. Used to measure reverse traction pressure. Figure 59 Test Port I (Figure 62) located on front traction circuit 1.
Cleaning The traction assist valve (Figure 63) is used to boost the pressure in the counterbalance circuit. Recommended traction assist counterbalance pressure is 700 psi Servicing the Spark Arrestor when traction pressure is above 1800 psi. Rotate the screw (Figure 63) clockwise to increase the pressure or Muffler counterclockwise to decrease the pressure.
B. Clean the battery, terminals, and posts with a wire brush and baking soda solution. C. Coat the cable terminals and battery posts with Grafo 112X skin-over grease (Toro Part No. 505-47) or petroleum jelly to prevent corrosion. D. Slowly recharge the battery every 60 days for 24 hours to prevent lead sulfation of the battery.
