SAFETY
• 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.
• 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 in this circuit can not occur after the
chassis cable (normally negative, black)is
removed from the battery.
• Use protective goggles.
• 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.
WARNING!
Avoid electrical sparking and its
consequences by the following
routines:
6003-009
Do not smoke when performing maintenance on the battery.
The
battery can explode
and cause serious
injury/damage.
• Disconnect the chassis cable from the battery first
and reconnect it last.
• Do not make a bridge short circuit across the
starter relay to run the starter.
• 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.
• 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.
• The blades are sharp and can cause cuts and
gashes. Wrap the blades or use protective gloves
when handling them.
• Check the parking brake's functionality regularly.
Adjust and service as necessary.
• The mulch blades should only be used in familiar
areas when higher quality mowing is desired.
• 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.
