7.7 Ledger Blades:
Each machine is equipped with a ledger (stationary) blade that
acts as a shear for the moving rotor blades.
The ledger blade is designed with 4 usable corners. When the
corner facing the rotor blade rounds over, remove the blade
and re-install with a different corner facing the rotor blade.
It is recommended that the clearance between the rotor and
stationary blades be set and maintained at 1/32 to 1/16 " (.76 -
1.52 mm) to obtain the best performance.
1.
Ensure the engine is off (ignition switch is off and the fuel
valve is closed).
2.
Remove the 2 bolts that hold the ledger blade to the ledger
mount, remove the blade.
3.
Rotate the blade and replace or replace with new or
re-sharpened blade.
4.
Hand tighten the bolts and set the clearance between the
ledger and rotor blades at 1/32 - 1/16" (.76 - 1.52 mm).
For fast and easy setting, use our chipper clearance setting
gauge, available from your dealer (see accessories)
5.
Tighten down bolts as specified in the torque chart
7.8 Twig Breaker:
The Twig Breaker is a breaker tab located on side of the lower
rotor housing. The discharge paddle passes around the twig
breaker and helps to break the material into smaller pieces and
turn it into mulch. Inspect the twig breaker for damage such
as gouges, a bent, or missing tooth. A damaged twig breaker
should be replaced. If the tooth is showing wear, remove and
replace the twig breaker.
1.
Ensure the engine is off (ignition switch is off and the fuel
valve is closed).
2.
Remove the 2 bolts and nuts that hold the twig breaker to
the housing, remove the twig breaker.
3.
Reverse the steps to install the new twig breaker.
