English • Replacement Saw Chain - A chain that complies with kickback performance requirements of ANSI B175.1-2000 when tested with specific chain saws. It may not meet the ANSI performance requirements when used with other saws. • Saw Chain - A loop of chain having cutting teeth, that cut the wood,and that is driven by the motor and is supported by the guide bar. • Ribbed Bumper - The ribs used when felling or bucking to pivot the saw and maintain position while sawing. • Switch - A device that when operated will complete or interrupt an electrical power circuit to the motor of the chain saw. • Switch Linkage - The mechanism that transmits motion from a trigger to the switch. • Switch Lockout - A movable stop that prevents the unintentional operation of the switch until manually actuated. Additional Safety Information WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT: • ANSI Z87.1 eye protection (CAN/CSA Z94.3), • ANSI S12.6 (S3.19) hearing protection, • NIOSH/OSHA/MSHA respiratory protection.
