FIG. 26: Engine is equipped with an electric starting aid.
Do not use aerosol starting fluid! Use of this fluid can
cause an explosion that can result in severe injury or
death.
TIRE SAFETY
FIG. 27: Tire explosion and/or serious injury can result
from over inflation. Do not exceed the tire inflation
pressures. See the Specifications Section for the correct
tire pressure.
Replace worn or damaged tires. When tire service is
needed, have a qualified tire mechanic service the tire.
See the Specifications Section for the correct tire size.
Do not weld on the rim when a tire is installed. Welding
will cause an explosive air/gas mixture that will ignite with
high temperatures. This can happen to tires that are
inflated or deflated. Removing the air or breaking the
bead is not enough.

FIG. 28: Electrical storage batteries give off highly
flammable hydrogen gas. Keep lighted smoking material
and open flame or electrical sparks away from the battery.
Do not lay tools or other conductive materials on the
battery.
Be careful when connecting booster cables to combine
batteries. Electrical component damage or battery
explosion can result if booster cables are not installed
correctly.
Do not charge a frozen battery as the battery can
explode. Warm battery to 16°C (60°F).
FIG. 29: Fluid in electrical storage batteries contains
sulfuric acid. Avoid all contact of fluid with eyes, skin or
clothing. If contact does occur, flush off immediately with
large amounts of water.
ACCUMULATOR SAFETY
FIG. 30: The accumulator (1) is charged with dry
nitrogen gas. Use only dry nitrogen when charging the
accumulator. Do not use air or oxygen or an explosion will
occur.
Do not drop the accumulator. A charged accumulator
contains nitrogen under pressure. If the shut off valve
breaks away from the accumulator, the escaping nitrogen
will propel the accumulator at a high rate of speed.
mCAUTION: Service of the accumulator must
be done by authorized personnel only.
Nitrogen gas when released can cause
localized freezing and injury.
