General Maintenance - Husqvarna MZ52 Operator's Manual

• Never fill containers inside a vehicle or on a truck or trailer
bed with plastic liner. Always place containers on the
ground away from the vehicle when filling.
• Remove gas-powered equipment from the truck or trailer
and refuel it on the ground. If this is not possible, refuel
such equipment with a portable container, rather than from
a gasoline dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.
• If fuel is spilled on clothing, change clothing immediately.
• Never overfill fuel tank. Replace gas cap and tighten
securely.
• Do not start the engine near spilled fuel.
• Never use gasoline as a cleaning agent.
• If leaks arise in fuel system, engine must not be started until
problem has been resolved.
• Check the fuel level before each use and leave space for
the fuel to expand, as the heat from the engine and the sun
may otherwise cause the fuel to expand and overflow.

General Maintenance

WARNING! The engine and the exhaust system
become very hot during operation.
There is risk for burns if touched.
Allow engine and exhaust system to cool before refueling.
• Never operate machine in a
closed area.
• Keep all nuts and bolts tight
to be sure the equipment is
in safe working condition.
• Maintain or replace safety
and instruction labels, as
necessary.
• Never tamper with safety
devices. Check their proper operation regularly.
• Do not modify safety equipment. Check regularly to be
sure it works properly. The machine must not be driven
with defective or unmounted protective plates, protective
cowlings, safety switches, or other protective devices.
• Do not change the settings of governors and avoid
running the engine with overly high engine speeds. If you
run the engine too fast, you risk damaging the machine
components.
• Keep machine free of grass, leaves, or other debris
buildup. Clean oil or fuel spillage and remove any fuel-
soaked debris. Allow machine to cool before storing.
• If you strike a foreign object, stop and inspect the machine.
Repair, if necessary, before restarting.
• Never make any adjustments or repairs with the engine
running.
• Check grass catcher components and the discharge guard
frequently and replace with manufacturer's recommended
parts, when necessary.
SAFETY
WARNING! The engine must not be started when
the driver's floor plate or any protective plate for the mower
deck's drive belt is removed.
• Mower blades are sharp. Wrap the blade or wear gloves,
and use extra caution when servicing them.
• Check brake operation frequently. Adjust and service as
required.
• Make sure that the equipment is in good condition and
that all nuts and bolts, especially those fastening the blade
attachments, are properly tightened and torqued.
• Ensure that the fuel filler cap is mounted tightly and no
flammable substances are stored in an open vessel.
• Never work with the starter circuit if there is spilled fuel.
• Sparking can occur when
working with the battery
and the heavy cables of
the starter circuit. This can
cause battery explosion,
fire or eye injury. Sparking
will not occur after the
grounding cable (normally
negative, black) is removed
from the battery. Disconnect
the grounding cable from the battery first and reconnect it
last.
• Do not make a bridge short circuit across the starter relay
to run the starter.
• Be very careful when handling battery acid. Acid on skin
can cause serious corrosive burns. If you spill battery acid
on your skin, rinse immediately with water.
WARNING!
The battery contains lead and lead compounds, chemicals
that are considered to cause cancer, birth defects, and
other reproductive system damage. Wash your hands after
handling the battery.
• Acid in the eyes can cause blindness, contact a doctor
immediately.
• Be careful when servicing
the battery. Explosive gases
form in the battery. Never
perform maintenance on the
battery when smoking or
near open flames or sparks.
• The battery can explode
and cause serious injury or
damage.
• Never use the machine
indoors or in spaces lacking proper ventilation. The exhaust
fumes contain carbon monoxide, an odorless, poisonous,
and lethal gas.
• Stop to inspect the equipment if you run over or into
anything. If necessary, make repairs before starting.
• Never make adjustments with the engine running.
