General Maintenance - Husqvarna W436 Operator's Manual

• 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 leaks arise in fuel system, engine must
not be started until problem has been
resolved.
• Never store the machine or fuel container
where there is an open flame, spark, or
pilot light such as on a water heater or
other appliance.
• Do not use gas with methanol. Methanol
is harmful to your health and to the
environment.

General Maintenance

• Never use the
machine indoors
or in spaces
lacking proper
ventilation. The
exhaust fumes
contain carbon
monoxide,
an odorless,
poisonous, and lethal gas.
• Keep all nuts and bolts tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices. Check
their proper operation regularly.
• 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 the discharge guard frequently and
replace with manufacturer's recommended
parts, when necessary.
• 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.
• Maintain or replace safety and instruction
labels, as necessary.
• Check wheel hardware tightness often
during the first 100 hours of operation.
Wheel hardware must be tightened
to specified torque using the proper
procedure anytime it is loosened.
• Do not modify safety equipment. Check
regularly to be sure it works properly. The
machine must not be used 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.
• Use protective goggles.
• Ensure that the fuel filler cap is mounted
tightly and no flammable substances are
stored in an open vessel.
• The machine is tested and approved only
with the equipment originally provided or
recommended by the manufacturer. Only
use approved repair parts for the machine.
• Reduce the risk of fire by removing grass,
leaves, and other debris that may have
accumulated on the machine. Allow the
machine to cool before putting it in storage.
• Hydraulic hoses and lines can fail due
to physical damage, kinks, age, and
exposure. Check hoses and lines regularly.
Replace damaged hoses and lines.
• Hydraulic fluid connections can loosen
due to physical damage and vibration.
Check connections regularly. Tighten loose
connections.
• Escaping fluid under pressure can
penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure
before disconnecting hydraulic or other
lines. Tighten all connections before
applying pressure.
• Search for leaks with a piece of cardboard.
Protect hands and body from high pressure
fluids.
• If an accident occurs, see a doctor
immediately. Any fluid injected into the
skin must be surgically removed within
a few hours or gangrene may result.
Doctors unfamiliar with this type of injury
should reference a knowledgeable medical
source.
• Always maintain the correct tire pressure.
Do not inflate the tires above the
recommended pressure. Never weld or
heat a wheel and tire assembly. The heat
can cause an increase in air pressure
resulting in a tire explosion. Welding can
structurally weaken or deform the wheel.
