condition.
• Symptoms can increase in cold temperatures. Use
warm clothing and keep your hands warm and dry
when you operate the product in cold environments.
• Do maintenance on and operate the product as
given in the operator's manual, to keep a correct
vibration level.
• The product has a vibration damping system that

• Birth defects
• Skin inflammation
• Use correct equipment to decrease the quantity of
dust and fumes in the air and to decrease dust on
work equipment, surfaces, clothing and body parts.
Examples of controls are dust collection systems
and water sprays to bind dust. Decrease dust at the
source where possible. Make sure that the
equipment is correctly installed and used and that
regular maintenance is done.
• Use approved respiratory protection. Make sure that
the respiratory protection is applicable for the
dangerous materials in the work area.
