Safety and Instruction Decals

The decals are designed to give the operator brief informa-

tion needed in the daily operation and service of the mower. 
These decals are not intended to be used in place of this 
manual but instead are to be used as an extension of this 
manual. These decals should not be removed or obliterated. 
Replace these decals if they become unreadable.

It is the

 owner’s responsibility 

to make certain that the 

operators and mechanics read and understand this 
manual and all decals before operating this mower. 

It is also the

 owner’s responsibility

 to make certain that 

the operators and mechanics are qualified and physi-
cally able individuals, properly trained in the operation 
of this equipment. 

All operators and mechanics must become familiar 
with the safe operation of the equipment, operator 
controls and decals. 

Never let children or untrained people operate or ser-
vice the equipment. Local regulations may restrict the 
age of the operator.

The owner/user can prevent and is responsible for 
accidents or injuries occurring to themselves, other 
people or property.

The owner should also ensure that the operators/
mechanics know that they are responsible for their 
own safety as well as the safety of other persons 
within the vicinity. 

Remember,

 the operator is responsi-

ble for accidents or hazards occurring to other people 
or their property.

 

The following illustrations show the various safety decals 

that are located on the mower. A brief explanation, for those 
requiring one, is shown to help the operator understand the 
meanings of these decals.
     

 

 

Specific safety warning decals are located on the 
equipment near the immediate areas of potential 
hazards. These decals should not be removed or 
obliterated. Replace them if they become non-read-
able.
