The warning system in this manual identifies

potential hazards and has special safety messages that

help you and others avoid personal injury, even death.

DANGER, WARNING and CAUTION are signal

words used to identify the level of hazard. However,

regardless of the hazard, be extremely careful.

DANGER signals an extreme hazard that will cause

serious injury or death if the recommended

precautions are not followed.

WARNING signals a hazard that may cause serious

injury or death if the recommended precautions are

not followed.

CAUTION signals a hazard that may cause minor or

moderate injury if the recommended precautions are

not followed.

Two other words are also used to highlight

information. “Important” calls attention to special

mechanical information and “Note” emphasizes

general information worthy of special attention.

The left and right side of the machine is determined

by sitting on the seat in the normal operator’s

position.

(Fig. 10) and the tip of the rear blade to the flat

surface. If the front blade tip is not 1/8–1/4”

(4–7 mm) lower than the rear blade tip adjust
