Maintenance Safety
•
Park machine on level ground, move the motion
control levers out to engage the parking brake,
disengage the blade control switch, stop engine,
and remove key. Wait for all moving parts to
stop before leaving the operator’s position. Allow
the machine to cool before servicing, adjusting,
fueling, cleaning, or storing.
•
If you leave the key in the switch, someone could
accidently start the engine and seriously injure you
or other bystanders. Remove the key from the
switch before you perform any maintenance.
•
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 all guards, shields, switches, and all safety
devices in place and in proper working condition.
Frequently check for worn or deteriorating
components and replace them with genuine
Exmark 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 Exmark 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.
•
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.
•
Do not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands.
•
Carefully release pressure from components with
stored energy
•
Keep your hands and feet away from moving
parts or hot surfaces. If possible, do not make
adjustments with the engine running.
•
Keep all parts in good working condition
and all hardware tightened, especially the
blade-attachment hardware.
