General Maintenance - Husqvarna W548 Operator's Manual

SAFETY
• 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.
• Before refueling, minimize the risk of static
electricity by touching a metal surface.
• Do not fill containers in a vehicle or on a truck or
trailer bed with plastic liner. Place containers on
the ground away from the vehicle when filling.
• Do not overfill fuel tank. Fill the tank to the
bottom of filler neck.
IMPORTANT DO NOT OVERFILL! This
equipment and/or its engine may include
evaporative emissions control system
components, required to meet EPA and/
or CARB regulations, that will only function
properly when the fuel tank has been filled to
the recommended level. Overfilling may cause
permanent damage to evaporative emissions
control system components.
• Replace the gas cap and tighten securely.
• If fuel is spilled on clothing, change clothing
immediately.
• Do not start the engine near spilled fuel.
• Do not use gasoline as a cleaning agent.
• If leaks occur in fuel system, the 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

• Do not use the
machine indoors or
in spaces lacking
proper ventilation.
The exhaust
fumes contain
carbon monoxide,
an odorless and
poisonous lethal gas.
• 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.
• Maintain or replace safety and instruction labels
as necessary.
• Do not interfere with the intended function of a
safety device or reduce the protection provided
by a safety device. Check their proper operation
8
regularly. NEVER operate a machine with a
safety device that does not function properly.
• To reduce the risk of fire, keep the machine free
of grass, leaves or other debris buildup. Clean
oil or fuel spills and remove fuel-soaked debris.
Let machine cool before storing.
• Stop to inspect the equipment if you run over or
into anything. If necessary, make repairs before
starting.
• Do not make adjustments or repairs with the
engine running.
• The blades are sharp and can cause cuts and
gashes. Wrap blades or use protective gloves
when handling them.
• Check the park brake's functionality regularly.
Adjust and service as necessary.
• Do not work with the starter circuit if there is
spilled fuel.
• Make sure that the fuel filler cap is mounted
tightly and no flammable substances are kept in
an open vessel.
• 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.
• Acid in the eyes can cause blindness, contact a
doctor immediately.
• Be careful when servicing the battery. Explosive
gases form in the battery. Do not perform
maintenance on the battery when smoking or
near open flames or sparks. The battery can
explode and cause serious injury or damage.
• 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.
• Regularly clean the deck and the underside of
the deck. Do not spray the engine and electrical
components with water.
CAUTION! Use protective glasses
for maintenance work.
