SAFETY INSTRUCTIONS

PERSONAL PROTECTIVE EQUIPMENT

MOST CHAIN SAW ACCIDENTS HAPPEN
WHEN THE CHAIN TOUCHES THE OPERA-
TOR. You must use approved personal
protective equipment whenever you use the
machine. Personal protective equipment
cannot eliminate the risk of injury but it will
reduce the degree of injury if an accident does
happen. Ask your dealer for help in choosing
the right equipment.

• PROTECTIVE HELMET
• HEARING PROTECTION
• PROTECTIVE GLASSES

OR VISOR

• GLOVES WITH

SAW PROTECTION

• PROTECTIVE TROUSERS

WITH SAW PROTECTION

• BOOTS WITH SAW

PROTECTION, STEEL
TOE-CAP AND NON-SLIP
SOLE

Generally clothes should be
close-fitting without restricting
your freedom of movement.

• ALWAYS HAVE A FIRST

AID KIT NEARBY

Long or continuous exposure to high noise
levels may cause permanent hearing
impairment. Always wear approved hearing
protection when operating a chain saw.
