Maintenance Safety
WARNING
While maintenance or adjustments are being
made, someone could start the engine.
Accidental starting of the engine could
seriously injure you or other bystanders.
Remove the key from the ignition switch,
engage parking brake, and pull the wire(s)
off the spark plug(s) before you do any
maintenance. Also push the wire(s) aside so
it does not accidentally contact the spark
plug(s).
WARNING
The engine can become very hot. Touching a
hot engine can cause severe burns.
Allow the engine to cool completely before
service or making repairs around the engine
area.
•
Park machine on level ground, disengage drives,
set parking brake, stop engine, remove key or
disconnect spark plug wire. Wait for all movement
to stop and allow the machine to cool before
adjusting, cleaning or repairing. Never allow
untrained personnel to service machine.
•
Disconnect battery or remove spark plug wire
before making any repairs. Disconnect the
negative terminal first and the positive last.
Reconnect positive first and negative last.
•
Keep the machine, guards, shields and all
safety devices in place and in safe working
condition. Frequently check for worn or
deteriorating components and replace them with
the manufacturer’s recommended parts when
necessary.
WARNING
Removal or modification of original
equipment, parts and/or accessories
may alter the warranty, controllability,
and safety of the machine. Unauthorized
modifications to the original equipment or
failure to use original Toro parts could lead
to serious injury or death. Unauthorized
changes to the machine, engine, fuel or
venting system, may violate applicable
safety standards such as: ANSI, OSHA and
NFPA and/or government regulations such
as EPA and CARB.
WARNING
Hydraulic fluid escaping under pressure
can penetrate skin and cause injury. Fluid
accidentally injected into the skin must be
surgically removed within a few hours by
a doctor familiar with this form of injury or
gangrene may result.
– If equipped, make sure all hydraulic
fluid hoses and lines are in good
condition and all hydraulic connections
and fittings are tight before applying
pressure to hydraulic system.
– Keep body and hands away from
pinhole leaks or nozzles that eject high
pressure hydraulic fluid.
– Use cardboard or paper, not your hands,
to find hydraulic leaks.
– Safely relieve all pressure in the
hydraulic system by placing the motion
control levers in neutral and shutting off
the engine before performing any work
on the hydraulic system.
WARNING
Fuel system components are under
high pressure. The use of improper
components can result in system failure,
gasoline leakage and possible explosion.
Use only approved fuel lines and fuel filters
for high pressure systems.
•
Use care when checking blades. Wrap the
blade(s) or wear gloves, and use caution when
servicing them. Only replace damaged blades.
Never straighten or weld them.
