Safety Instructions

12.Disengage the PTO clutch when transporting the machine.

13.Do not operate across the face of slopes. Use extreme caution when changing direction on slopes. Do not attempt to clear steep slopes.

14.Never adjust gauge wheels or skid shoes with the engine running. Before adjusting height or servicing, disengage the PTO clutch, stop the engine, and remove the ignition key. Wait for all movement to stop before getting off the seat.

NOTE: The PTO brake should normally stop drive line rotation within 5 seconds of disengag- ing the PTO clutch.

15.Do not operate the snowblower with the blower spout assembly removed.

16.If snowblower clogs:

a.Disengage the PTO clutch, stop the en- gine, and remove the ignition key before leaving the seat.

b.LOOK to make sure PTO shaft and auger movement has stopped before trying to un- clog the snowblower.

c.Disconnect the fuel solenoid wire [diesel engines] or spark plug wire(s) [gasoline engines].

d.Do not use hands or feet to unclog the snowblower - use a stick or similar tool.

17.If the implement strikes a solid object or the ma- chine begins to vibrate abnormally, immediately disengage the PTO clutch, stop the engine, and wait for all moving parts to stop. Dis- connect the fuel solenoid wire [diesel engines] or the spark plug wire(s) [gasoline engines] to pre- vent accidental starting. Thoroughly inspect the implement and repair any damage before re- starting the engine and operating the machine. Make sure implement components are in good condition and all bolts are tight.

18.Do not touch the engine or muffler while the engine is running or immediately after stopping the engine. These areas may be hot enough to cause serious burns.

19.When leaving the machine unattended, disen- gage the PTO clutch, stop the engine, and re- move the ignition key.

MAINTENANCE

NOTE: Refer to the Walker Rider Lawnmowers OWNER’S MANUAL for proper tractor mainte-

nance procedures.

2.To reduce fire hazards, keep the engine free of grass, leaves, excessive grease, and dirt.

3.Keep all nuts, bolts, and screws tight to ensure the machine is in a safe, working condition.

4.Perform only maintenance instructions de- scribed in this manual. Unauthorized mainte- nance operations or machine modifications may result in unsafe operating conditions.

5.If the engine must be running to perform a main- tenance adjustment, keep hands, feet, and clothing away from moving parts. Do not wear jewelry or loose clothing.

6.Always use proper engine service manuals when working on the engine. Unauthorized maintenance operations or modifications to the engine may result in unsafe operating condi- tions.

7.Altering the machine in any manner which ad- versely affects its operation, performance, dura- bility, or use will VOID the warranty and may cause hazardous conditions.

8.Never attempt to disconnect any safety devices or defeat the purpose of these safety devices.

9.Do not change the engine governor settings or overspeed the engine. The governor has been factory-set for maximum-safe engine operating speed.
