Thispage left intentionallyblank.

TO AVOID SERIOUS iNJURY:

Do not operate on uneven ground where unit is

unstable. Do not operate on pavement, gravel or

other hard surfaces since objects can ricochet

and cause injury.

To avoid a fire hazard, keep leaves, grass, and other

combustible materials away from hot engine and

muffler.

Keep children and others away from area of

operation.

Wear approved safety glasses, gloves and ear

protection.

ROTATING CUTTING BLADES.

TO AVOID SERIOUS INJURY:

• Read the owner's manual(s) before starting and

using unit.

Keep all shields and guards in place and securely

attached.

Keep hands, feet, face, clothing and long hair out of

Shredder Hopper, Chipper Chute and Discharge

Chute while the engine is running. Rotating cutting

blades inside these openings will cause serious

personal injury if contacted. Material being

_rocessed

may bounce back from inlet openings or be thrown

from the discharge chute. Long hair or loose clothing

may be pulled sucked into the inlet openings.

. Do not place branches over 1/2 inch diameter into

the large Shredder Hopper. Branches over I/2 inch in

diameter should be placed in the Small Chipper

Chute.

. If the chipped shredder jams or becomes clogged,

immediately shut off the engine and wait for all

moving parts to come to a complete stop before

clearing.

. Do not install remove, adjust, or service the

discharge screen or any other part while the engine

is running. Blade contact can occur.

KEEP HANDS AND FEET OUT

OF OPENINGSWHILE MACHINE
