MAINTENANCE
1. To prevent accidental starting of the engine
when servicing or adjusting the machine, re-
move the key from the ignition switch and dis-
connect the electrical plug on the fuel shut-off
solenoid.
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.
Check the blade mounting nuts frequently, mak-
ing sure they are tight.
4. Perform only maintenance instructions de-
scribed in this manual. Unauthorized main-
tenance 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 the proper engine service man-
ual when working on the engine. Unautho-
rized maintenance operations or modifications
to the engine may result in unsafe operating
conditions.
7. The fuel oil injection system operates under
high pressure and can penetrate the skin and
result in serious injury. Unqualified persons
should not remove or attempt to adjust a pump
injector, nozzle, or any part of the fuel injection
system.
8. Altering the equipment or engine in any manner
which adversely affects its operation, perfor-
mance, durability, or use will VOID the warran-
ty and may cause hazardous conditions.
9. Never attempt to disconnect any safety devices
or defeat the purpose of these safety devices.
10. Do not change the engine governor settings or
overspeed the engine. The governor has been
factory-set for maximum-safe engine operating
speed.
11. Use genuine factory replacement parts.
Substitute parts may result in product malfunc-
tion and possible injury to the operator and/or
others.
12. Use care when charging the battery or per-
forming maintenance on the battery and electri-
cal system:
a. Make sure the battery charger is unplugged
before connecting or disconnecting cables
to the battery.
b. Charge the battery in a well-ventilated
space, so gases produced while charging
can dissipate. Make sure the battery vents
in the caps are open.
c. Keep sparks, flames, and smoking materi-
als away from the battery at all times. To
avoid sparks, use care when removing bat-
tery cables from posts.
d. Disconnect both battery cables before
unplugging any wiring connectors or mak-
ing repairs on the electrical system.
IMPORTANT: Keep all applicable manuals
immediately accessible to anyone who may
operate or service this machine.
