Always use a push stick when jointing an edge if the

stock width is shorter than the height of the fence.

(Notice that left hand is PAST the cutters)

direct contact with the flat side of the stock as it is passed through the unit. It is WRONG for

operators to use the pusher block on the back of the stock with their right hand while

pushing down on the front portion of the stock with their left hand. It cannot be stressed

enough that operators must use one of the yellow hold down blocks in the FRONT with

the left hand AND a pusher block in the BACK of the stock. If the stock should happen to

slip for any reason, it would be better to see flying bits of yellow plastic rather than bits of

fingers and blood!

• Hand Pressure and Placement: Your hands should be over the infeed table to get the piece

started and to guide the piece until there is enough wood flat on the outfeed table. Then

apply pressure on the outfeed surface to keep the machined edge of the wood flat, which

forces the rest of the board to follow on the flat cut line.

• Minimizing Chipping or Tearout: To get the best surface possible from the jointer, its knives

have to cut down or with the grain on the final finishing passes.

On some pieces however, particularly when jointing the wide face, reading grain can be very

difficult. Occasionally, taking very light cuts (1/32” max) in both directions and inspecting

the surface between will reveal which produces the smoothest cut. For more information

on reading grain direction, see Section 4.1 Reading Grain Orientation.

• Defective Boards:

o If the defect is big, it may be better to reduce its severity with a preliminary cut using a

saw. For more on this technique, see Section 5.4 Preparing Wood for the Jointer. This

additional step can save time, wood and help reduce tapering of the board.

o If the wood has a defect such as an arch or bow, apply enough pressure before and after

the cutter head to keep the board as level to the table as possible during the initial cuts.

Then, as soon as the jointer begins making a flat surface on the leading edge, pressure

Never have your hand directly on

top of the workpiece when the

cutter head is beneath your hand.

Use push tools instead of your hand.
