BALANCING THE BLADE
See Fig 10-B
When sharpening, care should be taken to keep the
blade balanced. An unbalanced blade will cause
excessive vibration when the mower is running. This
vibration will eventually cause damage to the mower,
especially the motor.
To check the blade balance:
■ Clamp a screwdriver (or nail shank) horizontally in a
vise as shown.
NOTE: If a vise is not available, a straight nail can also
be used.
■ Place the center hole of blade on the screwdriver(or
nail) shank.
■ If blade is balanced, it will remain in a horizontal
position. If either end of the blade drops downward,
sharpen the heavy side until the blade is balanced.
REPLACING WHEELS
See Fig 11
■ Disconnect the mower from the power supply.
■ Turn the mower on its side.
■ Using a fl at blade screwdriver, pry off the hubcap.
■ Remove the wheel and replace with new wheel .
■ Replace hubcap.
