you use it. Check for the following conditions and
repair or replace when necessary.

General
Knife Sharpening
Knife sharpness is one of the most important fac-
tors in getting good results with the planer. Knives
can be made to last a long time if care is taken in
checking the condition of the wood which is put
into the machine. The biggest problem will come
from wood with nails or other metal embedded.
This will nick or chip the knives and can require a
complete regrinding. Another wear factor is sand,
grit, or other dirt on the surface of the wood which
the knives have to cut through. At the speed the
cutterhead is rotating, these types of surface con-
tamination can have a very abrasive effect.
This planer has knives with a grind angle of 45˚
which is a configuration which should suit most
general planing needs. The optimal grind or bevel
angle is a compromise between effective cutting
(the smaller the angle the better the cutting
action) and edge life where the larger the angle
the more the edge is supported, thus the longer it
will last.
For the best results it is best to have planer
knives sharpened by a professional sharpening
service which has the grinding and measurement
equipment to assure that the knife cutting geom-
etry is maintained at optimum levels. It is a pro-
cedure which requires some care and precision,
otherwise a set of blades can be easily ruined.
Knives should always be ground as a set so they
can be properly matched. Unequal material
removal can result in an unbalanced cutterhead
which can affect not only planing surface quality
but ultimately the life of the cutterhead bearings.
Please refer to Section 5 Adjustments - Knife
Adjustments for complete detail on the removal
and reinstallation of the planer knives.
DO NOT make adjustments or attempt any
maintenance procedures while this machine
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making any adjust-
ments. Failure to follow this directive could
result in serious operator injury.
