DRIVE BELT REPLACEMENT
The KN AP-125B features a very durable drive belt which
is located on the right side of the planer and may eventually
require replacement.
TO REPLACE THE DRIVE BELT:
Disconnect the cord from the power source.
Uninstall the crank handle, the top cover and the side panels.
Loosen the two screws securing the belt guard and remove
the belt guard.
Roll the belt off the pulleys.
Position the new belt around the motor pulley so that the ribs
of the belt are seated in the pulley grooves.
Apply pressure to the pulley with one hand and slowly rotate
the motor pulley and install the belt on both pulleys.
When the belt is fully on both pulleys, rotate the pulleys with
your hand and make sure the belt is properly installed onto
the pulleys and the ribs of the belt are seated in the pulley
grooves.
Reinstall the belt guard, side panels, top cover and the crank
handle.

TO INSTALL THE KNIVES
Rotate the cutter head with the knife slot facing directly up
so that the springs do not fall out, then remove the gib.
Clean the knife, the gib and the knife slot with a shop rag
and apply a light coat of oil on these parts.
Make sure the spring are properly in position and replace
the gib.
Insert the knife into the knife slot between the gib and cutter
head so that the bevelled edge of the knife is against
the cutter head.
Position the knife gauge over the knife and apply downward
pressure.
While maintaining pressure on the knife with the knife gauge,
tighten the gib bolts just enough to hold the knife in place
starting with the middle bolt as shown in figure-10.

Position the knife gauge on the cutter head and check
the height of the knife. The tip of the knife should be just
touching the arc of the gauge.
If the knife is not secured at the correct height, loosen all
the bolts and repeat the above four steps to correct
the height.
Install the second knife, in the same way.
