Knives
(Model G9953 Only)
Setting the knives correctly is crucial to the prop- er operation of the jointer and is very important in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, dull much faster than the others. Note— The cutterhead knives should protrude above the cutterhead 2mm (0.079"). The knife jig included with the jointer is designed to set the knives with- in this height.
To set the knives:
1.Unplug the machine from the power source!
2.Open the access door on the back of the machine, just below the fence adjustments.
3.Turn the cutterhead pulley until the surface of the cutterhead is at top dead center.
4.Adjust the outfeed table to a height of 2mm above the surface of the cutterhead.
5.Turn the cutterhead pulley to reveal one of the knives.
6.Loosen the cutterhead gib bolts, starting in the middle, and alternating back and forth until all of the gib bolts are loose, but not falling out (Figures 34 and 35).
