Pow’R’kraft Chipper 13
Revision 9/22/16
NOTE: There are two bearings, one outside
and the other inside of the housing. The
bearings are greased when they are new,
however it is a good idea to grease them after
a couple of hours use. One or two pumps are
sufficient. Be careful not to over grease. Over
lubrication can damage the bearings.
If the machine’s cutting disk strikes a foreign
object, or if the machine begins to make
an unusual noise or vibrates excessively,
immediately shut off the engine. Allow the
cutting disk to come to a complete stop.
Remove the spark plug from the engine to
avoid any accidental start. Then perform the
following steps:
• Insp ect for d am ag e.
• Rep air or rep lace d am ag ed p art s.
• Ch ec k f o r an y lo o se p ar t s an d t ig h t en t o
ensure continued safe operation.

efficiency. Using dull knives or a rounded
wear plate will decrease performance and
cause excessive vibration that will damage the
machine and make chipping difficult for the
operator.
Knife Removal and Replacement
This wood chipper is equipped with two
pieces of chipper knives mounted on the
cutting disk. When the knives get dull or show
visible nicks, the machine will lose its self-
feeding action and the material has to be
pushed in. Often it comes out in long strips.
T h e k n i v e s n e e d t o b e r e m o v e d f o r
sharpening. To remove the knives, loosen the
clamp by unscrewing the locknut to open the
discharge chute and remove the feed hopper.
With a 13 mm ring spanner loosen the locknuts
at the back of the cutting disk. If the bolt head
turns, hold it with a 5 mm hexagonal Allan
key. Do not try to loosen the bolt with the
hexagonal Allan key.
