Servicing the Blades

Service Interval: Yearly
Important:
You will need a torque wrench to
install the blades properly. If you do not have a
torque wrench or are uncomfortable performing
this procedure, contact an Authorized Service
Dealer.
Examine the blades whenever you run out of fuel. If
the blades are damaged or cracked, replace them
immediately. If the blade edges are dull or nicked,
have them sharpened and balanced, or replace them.

WARNING
When servicing the blade, the blade can still
move even though the power source is off.
The blade is sharp; contacting the blade can
result in serious personal injury.
• Keep your hands and feet away from a
moving blade.
• Wear gloves when servicing the blade.
Note:
Maintain sharp blades throughout the cutting

tearing or shredding the grass blades.
