Infeed and outfeed rollers (Key Nos. 36 and 35) feed
the workplace under the cutterhaad.

prevent rollers from slipping.
The spring tension on feed rollers must be sufficient
enough to prevent rotlers from slipping on wcrkpiece,
but tension must not be so great that rollers cause
damage to the workplace.
• If feed milers slip on workpfece, spring tension must
be increased.

springtension must be decreased.
• Adjust the springtension on the feed rollersby rotat-
ingthe adjustment screws (Key No. 53) at each end

CHECKING FOR WORN BLADES
• The condition of the blades will affect the precision
of the cut. To check the condition of the blades,
observe the quality of cut which planer produces.
• Dull blades will tear, rather than sever wood fibers,
and produce a fuzzy appearance.
• A raised grain will ocour when dull blades pound on
wood that has a varying density.
• A raised edge will be produced where the blades
have been nicked.
SHARPENING BLADES
The blades can be honed individually by whetting them
with fine sharpening stone. Make sure oilstone is flat
and is not worn. To sharpen blades:
• Partially cover stone with paper to protect the table
top.
• Position infead table so stone will contact blade
along its beveled surface.
• Stroke the stone across blade from one side to other
while stone is also moving slightly in the direction of
feed.
• Make sure to do the same amount of strokes on
each blade.
tf the blades are nici_d they must be replaced or
reground. Never install unbalanced blades. Always
sharpen blades in sets of three.
NOTE: Many shops do not have capabilities to
resurface blades. Yellow pages should list "Sharpening
Services" or "1"ool Grinding".
