4. Remove front jam nut securing switch to mounting
bracket and remove switch.
5. Install new PTO switch to mounting bracket. Adjust
switch so it is depressed 1/2” (13 mm) when PTO lever
is moved to OFF position. Tighten jam nuts to 75 in–lb.
Reinstall boot to switch.
IMPORTANT: Switch threads will be damaged if jam
nuts are over tightened.
6. Connect a continuity tester or ohm meter to switch
connector. With PTO lever in the ON position the switch
circuit should not have any continuity. If there is
continuity, recheck switch installation. If there is no
continuity, proceed to next step.
7. Move PTO lever to the OFF position. When PTO
lever is in its normal, released position, the PTO switch
should have continuity. If there is no continuity, recheck
switch installation. If there is no continuity, proceed to
next step.
8. Push switch connectors together.
9. Connect battery cable and install instrument cover.

SERVICING BATTERY
IMPORTANT: Before welding on the machine,
disconnect ground cable from the battery to
prevent damage to the electrical system.
Note: Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery
case clean because a dirty battery will discharge slowly.
To clean the battery, wash the entire case with solution
of baking soda and water. Rinse with clear water. Coat
the battery posts and cable connectors with Grafo 112X
(skin–over) grease (Toro Part No. 505-47) or petroleum
jelly to prevent corrosion.
