While Doing Maintenance, Troubleshooting, Testing, Adjustments or Repairs
20. Remove the key from the ignition switch and discon­
nect the negative (–) cable from the battery. Secure the
cable off to the side. This will prevent sparks, electrical
shocks, or accidental starting of the engine when serv­
icing, cleaning, adjusting, or storing the machine.
21. Be sure you understand a service procedure before
working on the machine. Unauthorized modifications to
the machine may impair the function, safety and life of
the machine. If major repairs are ever needed, or assis ­
tance is desired, contact an Authorized TORO Distribu­
tor or Dealer.
22. To reduce potential fire hazards, keep the engine
free of excessive grease, grass, leaves, and accumula ­
tion of dirt. Do not use flammable solvents for cleaning
parts. Do not use diesel fuel, kerosene or gasoline.
23. Be sure the machine is in good operating condition.
Keep nuts, bolts, and screws tight. Check all cutting
blade mounting bolts frequently for the proper torque;
75 to 100 ft.lbs (10.4 to 13.8 KgM).
24. If the engine must be running to perform an inspec ­
tion or procedure, use extreme caution. Always use two
people, with the operator at the controls able to see the
person doing the inspection or procedure. Keep hands,
feet, clothing, and body away from the P.T.O. shaft,
cutting unit blades, belts, cooling fan and other moving
parts.
25. Do not overspeed the engine by changing the gov ­
ernor settings. The maximum engine speed (with no
load and engine coupled to the transmission) is listed in
Chapter 3 - Mitsubishi Diesel Engine.

26. The engine must be stopped before checking the oil
level or adding oil to the crankcase.
27. Make sure all hydraulic line connectors are tight, and
all hydraulic hoses and lines are in good condition
before applying pressure to the system.
28. Keep body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not hands, to search for leaks.
Hydraulic fluid escaping under pressre can have suffi­
cient force to penetrate skin and do serious damage. If
fluid is injected into the skin, it must be surgically re ­
moved within a few hours by a doctor familiar with this
type of injury or gangrene may result.
29. Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the imple­
ment to the ground.
30. Wear safety glasses, goggles or a face shield to
prevent possible eye injury when using compressed air
for cleaning or drying components.
31. At the time of manufacture, the Groundsmaster
220-D conformed to safety standards in effect for riding
mowers. To assure optimum performance and safety of
the machine, always use genuine TORO replacement
parts and accessories. NEVER USE "WILL FIT" RE-
PLACEMENT PARTS AND ACCESSORIES MADE BY
OTHER MANUFACTURERS. Using unapproved re ­
placement parts and accessories could void the war­
ranty of your TORO mower.
