8.7.1 Ledger Knife Clearance
Use the Ledger Setting Gauge to check knife clearance
. The
thickness of the gauge is the correct ledger blade clearance.
If spacing is in excess of the gauge thickness, adjust the
clearance.
The actual clearance between the rotor blades and
the ledger knife is 1/32"–1/16" (3/4 – 1-1/2 mm).
Checking
1.
Open the upper rotor housing.
CAUTION!
Risk of getting hands pinched or wedged
between lower rotor housing and rotor. Turn
rotor slowly and be aware of hand positioning.

2.
Turn the rotor by hand so that one rotor blade edge is next
to the ledger knife.
3.
Slide the end of the ledger gauge down between the rotor
blade and the ledger knife.
