n Belt Tension
Always adjust the belt tension after changing the
belt. New belts may stretch. Excess tension on the
belt will make holding the clutch difficult and cause
the belts to wear.
To adjust belt tension (See Figure 9):
1. Remove the cotter pin from the lower control rod
and disconnect the lower control rod from the
idler pulley assembly.
2. To increase the belt tension, loosen the hex nut
and turn the lower control rod to shorten the rod.
Retighten the nut after the rod is reinstalled.

n Changing the Blade
The blade is sharp! Wear gloves when
changing the blade. Do not operate the edger
with a damaged or excessively worn blade.
Note: Blades must be balanced before installation
to prevent vibration and wear to the edger.
1. While holding the hex bolt head by the spindle
pulley, remove the nut and washer and carefully
remove the blade from the assembly (See Figure
10).
2. Install the new blade.
3. Replace the nut and washer.
4. Tighten the nut securely. Keep the spindle shaft
from rotating with a wrench on the hex nut located
on the pulley.
