Impeller Belt
the dust collection system on the Model g0689
is powered by a belt-driven impeller. the belt is
very durable, but with extended use it may begin
to slip, resulting in a reduction in dust collection
performance.

feed Rollers
the feed rollers rotate in bushing blocks that are
spring loaded. the feed rollers ride up on the
board so that the roller pressure is maintained.
if chips or sawdust build up between the bracket
and bushing block, the amount of roller vertical
travel will be reduced, potentially causing improp-
er feeding of lumber through the machine (
figure
39).
periodically check and clean chips and sawdust
from between the bushing blocks and brackets.
To clean the feed rollers:
1. diSConnECt planEr FroM poWEr!
2. remove the elevation crank and the top and
side covers. this provides easy access to
depress the rollers so that chips and sawdust
can be easily removed.
3. place a 4'' high block of wood between one
of the feed rollers and the planer bed. Ensure
that the block of wood is not under the
cutterhead.
4. lower the cutterhead assembly down just
enough so that the roller is pushed up against
the spring and pressure is off of the two
brackets.
5. remove any trapped material from between
the roller assembly and bracket.
