Sharpening Standard Knives

Knives should be kept sharp. This will contribute
to better stock finish, longer machine life, and
safer operation.
A jointer knife hone provides a simple way to
sharpen knives. Hones are available from many
woodworking supply stores. Carefully read any
instructions that accompany the hone.
Use caution and proceed
slowly when sharpening knives. Disconnect
jointer from power
approved eye protection.
When finished sharpening knives, they should
be re-set level with and parallel to the outfeed
table. See "Setting Knives at Correct Height and
Parallel to Outfeed Table" on page 18.
Knives can usually be whetted several times in
the cutterhead before having to be removed and
re-ground.
TIP: If the jointer is used frequently, keeping a
spare set of knives on hand is recommended.
Extra knives (stock no. 6296046, set of 3) may
be obtained from your distributor, or by calling
customer service at 1-800-274-6848.
