SAFETY RULES

Read, understand, and follow all safety practices in 
Owner/Operator Manual before beginning assembly. 
Failure to follow instructions could result in personal 
injury and/or damage to unit.

ALWAYS remove key from ignition and wire from spark 
plug before assembly. Unintentional engine start up 
can cause death or serious injury.

Complete a walk around inspection of unit and work 
area to understand:

• Work area

• Your unit

• All safety decals

Inspect unit before each use for: missing or damaged 
decals and shields, correctly operating safety interlock 
system, and deterioration of grass catchers. Replace or 
repair as needed.

ALWAYS check overhead and side clearances carefully 
before operation. ALWAYS be aware of traffic when 
crossing or operating along streets or curbs.

Keep children and people away.

Keep children out of work area and under watchful care 
of a responsible adult.

Keep area of operation clear of all toys, and debris. 
Thrown objects can cause injury.

Check for weak spots on docks, ramps or floors, Avoid 
uneven work areas and rough terrain. Stay alert for 
hidden hazards or traffic.

DO NOT operate near drop-offs, ditches, or 
embankments. Unit can suddenly turn over if a wheel is 
over the edge of a cliff or ditch, or if an edge caves in.

Data indicates that operators, age 60 and above, are 
involved in a larger percentage of riding mower related 
injuries. These operators should evaluate their ability to 
operate the riding mower safely enough to protect 
themselves and others from serious injury.

Read the entire Owner/Operator manual and other 
training material. If the operator or the mechanic 
cannot read the manual, it is the owner’s responsibility 
to explain it to them. Only the user can prevent and is 
responsible for accidents or injuries occurring to 
themselves, other people or property.

Only trained adults may operate unit. Training includes 
actual operation.
