from the product.
•Never use the product in bad
weather such as fog, rain,
strong winds, intense cold and
risk of lightning. To use the
product in bad weather or in
moist or wet locations is tiring.
Bad weather can cause
dangerous conditions, such as
slippery surfaces.
•Look out for persons, objects
and situations that can prevent
safe operation of the product.

•Use personal protective
equipment. Refer to
Personal
protective equipment on page
