SAFETY PRECAUTIONS

A. General

1.

Read this Operator’s Manual before starting 
the mower. Study the controls and learn the 
proper sequence of operation.

2.

Do not allow anyone to operate or maintain 
this machine who has not read this manual. 
Never permit children to operate this machine.

3.

Never carry passengers.

4.

Do not remove any shields, guards or safety 
devices. If a shield, guard or safety device is 
damaged or does not function, repair or 
replace it before operating the mower.

5.

Always wear safety glasses and safety shoes 
when operating or maintaining this mower. Do 
not wear loose-fitting clothing.

6.

Disconnect the spark plug wires and remove 
the key from the ignition to prevent the engine 
from accidentally starting before performing 
any maintenance on this mower.

7.

Never run the engine indoors without ade-
