MAINTENANCE
WARNING:
Turn the switch to OFF position and unplug
jointer/planer from power source before proceeding to do
maintenance work.
CHECKING FOR WORN BLADES
Condition of blades will affect precision of cut. If blade wear is not
observed when checking the blade height, the quality of cut will
indicate the blade condition. Dull blades will tear rather than sever
wood fiber. A raised grain will occur when dull blades pound on
wood where there is difference in density. A raised ridge will be
produced where the blades have been nicked.
SHARPENING BLADES
Refer to Figure 21.
The blades can be honed individually by whetting them with a fine
sharpening stone. Make sure oilstone is flat and is not worn. To
sharpen blades:
•
Partially cover the stone with paper to protect the table top.
•
Position infeed table so stone will contact blade along its
beveled surface.
•
Stroke the stone across blade from one side to other while
stone is also moved slightly in the direction of feed.
•
Make sure to do the same number of strokes on each place.
If the blades are nicked they must be replaced or reground. They
can be reground several times until they become
13
/
16
″
wide.
NOTE:
Many shops do not have capabilities to resurface blades.
Yellow pages should list “Sharpening Services” or “Tool Grinding.”
Never install unbalanced blades or reground blades less than
13
/
16
″
wide.
