24. Be sure the machine is in safe operating condition
by keeping nuts, bolts and screws tight. Check all
bolts and nuts frequently to be sure they are tight-
ened to specification.
25. If the engine must be running to perform a mainte-
nance adjustment, keep your hands, feet, clothing
and other parts of your body away from any moving
parts.
26. Make sure all hydraulic line connectors are tight, and
all hydraulic hoses and lines are in good condition
before applying pressure to the system.
27. Keep your body and hands away from pin hole leaks
or nozzles that eject water or hydraulic fluid under
high pressure. Use paper or cardboard, not your
hands, to search for leaks. Hydraulic fluid or water
escaping under pressure can have sufficient force to
penetrate your skin and do serious damage. If either
of these fluids are ejected into your skin they must
be surgically removed within a few hours by a doc-
tor familiar with this form of injury or gangrene
may result.
28. Before disconnecting or performing any work on the
hydraulic oil system, all pressure in the system
must be relieved by stopping the engine and open-
ing the by-pass valve.
29. Make sure all water line connectors are tight, and all
hoses and lines are in good condition before apply-
ing pressure to the system.
30. Before disconnecting or performing any work on the
water system, all pressure in the system must be
relieved by stopping the engine and opening the
bleed valve. Opening the bleed valve allows any
trapped water to escape from the system and also
allows the accumulator piston to move to the bot-
tom of the accumulator cylinder.
31. The accumulator in this machine contains high-
pressure dry nitrogen. Accumulator servicing
requires special tools and precautions.
Accumulators do not contain user-serviceable com-
ponents. Improper accumulator servicing can cause
dismemberment or death. Do not attempt to disas-
semble a accumulator; have this work done by a
14. Start the engine with the parking brake engaged.
15. Do not run the engine in a confined area without ade-
quate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
16. Using the machine demands attention, and to prevent
loss of control:
A. Use only in daylight or when there is good artifi-
cial light.
B. Watch for holes or other hidden hazards.
C. Do not transport the machine close to a sand
trap, ditch, creek or other hazard.
17. If the machine starts to vibrate abnormally, shut off
the engine. Remove the wires from the spark plugs to
prevent the possibility of accidental starting. Check
the machine for damage and defective parts. Repair
any damage before restarting the engine and operat-
ing the machine.
18. Do not touch the engine or muffler while the engine is
running or soon after it is stopped. These areas could
be hot enough to cause a burn.
19. Before leaving the operator's position behind the han-
dle engage the parking brake.
20. When leaving the machine unattended, engage the
parking brake , shut OFF the engine and remove the
key from the ignition switch.
MAINTENANCE
21. Disconnect the wires from the spark plugs to prevent
accidental starting of the engine when servicing,
adjusting or storing the machine.
22. If the machine must be tipped to perform maintenance
or an adjustment, close the fuel shut-off valve, drain
gasoline from the fuel tank, oil from the crankcase
and remove the battery.
23. To reduce potential fire hazard, keep the engine free
of excessive grease, grass, leaves and accumulations
of dirt.
