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.
MACHINE USE
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 un-
derway, the new surface rests firmly on the outfeed table
as shown in Fig. 38. The left hand should then be moved
to the work on the outfeed table, at the same time
maintaining flat contact with the fence. The right hand
presses the work forward, and before the right hand
reaches the cutterhead, it should be moved to the work
on the outfeed table.
NEVER PASS HANDS DIRECTLY OVER
THE CUTTERHEAD.
