traumatic amputation, or laceration.
Before performing adjustments or repairs:
•
Disconnect the spark plug wire and keep it away from
the spark plug.
•
Disconnect battery at negative terminal (only engines
with electric start).
•
Use only correct tools.

Check Tire Pressure
Tires should be checked periodically to provide the optimum
traction and to guarantee the best cut (see Figure 4).
NOTE: These pressures may differ slightly from the
"Maximum Inflation" stamped on the side walls of the tires.
Check Mower Blade Stopping Time
WARNING
If the mower blade does not come to a complete
stop within 5 seconds, the blade must be adjusted. Do not
operate the machine until the proper adjustment has been
performed by an authorized dealer.
Check the mower blade for proper function (see Safety
Interlock System Tests). The blade should stop rotating in
5 seconds or less after moving the blade control to the OFF
position.
