OPERATION
CUTTERHEAD ROTATION
The rotation of the cutterhead must be in a clockwise direction when viewed from the left side of the machine; that is, the knives must be rotating toward the infeed table from the top. If the cutterhead rotation is incorrect, disconnect the machine from the power source and proceed as follows:
Single Phase Machines – Interchange leads T5 and T8 in the motor junction box.
Three Phase Machines – Interchange any two of the three incoming power lines.
The following directions will give the beginner a start on jointer operations. Use scrap pieces of lumber to check settings and to get the feel of the operations before attempting regular work.
THE KNIVES ON THE JOINTER WILL NOT WEAR EVENLY BY FEEDING THE WOOD THROUGH THE SAME SPOT ON THE TABLE EVERY TIME. FEED THE WOOD THROUGH THE JOINTER AT DIFFERENT SPOTS ON THE TABLE WHEN POSSIBLE, TO HELP ELIMINATE UNEVEN WEAR OF THE KNIVES.
ALWAYS USE CUTTERHEAD GUARD AND KEEP HANDS AWAY FROM CUTTERHEAD. ALWAYS USE PUSH BLOCKS WHENEVER POSSIBLE. NEVER MAKE JOINTING AND PLANING CUTS DEEPER THAN 1/8" IN ONE PASS.
PLACEMENT OF HANDS DURING FEEDING
At the start of the cut, the left hand holds the work firmly against the infeed table and fence, while the right hand pushes the work toward the knives. After the cut is underway, the new surface rests firmly on the outfeed table as shown in Fig. 36. The left hand should then be moved to
the work on the outfeed table, at the same time maintaining 18 flat contact with the fence. The right hand presses the work forward, and before the right hand reaches the
it should be moved to the work on the outfeed table.
NEVER PASS HANDS DIRECTLY OVER THE CUTTERHEAD AND USE PUSH BLOCKS WHENEVER POSSIBLE.
