MAINTENANCE (CONT'D)
nBelt 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.

nChanging the Blade
CAUTION:
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.
