Knives
NOTICE
The Model G9953 is supplied with a 4 knife cutterhead, while the Models G9859/60/61 have 3 knife cutterheads.
Jointer knives are extremely sharp. Never grab the cutterhead directly to rotate it. Always use the drive pulley. Always be sure the jointer is disconnected from its power source before you make any adjustments. Serious personal injury may occur.
Note: The Model G9860ZX has a spiral cutter- head in place of the knife cutterhead. Adjustment will be discussed in the next section.
The knives of your jointer must be periodically replaced or adjusted. Adjustments should be as precise as possible with tolerances within .002"-
.003" to prolong the sharpness of the knife edges. Improperly adjusted knives can unbalance the cutterhead and shorten bearing life, as well as produce substandard jointing or planing results.
1.Unplug the jointer! Remove the cutterhead guard to expose the top of the cutterhead.
2.Carefully turn the cutterhead (using the pul- ley) until the first knife is at top dead center. Engage the brake rod to secure the cutter- head into a stationary position as shown in Figure 8.
3.Using the knife setting gauge, check the knife height. The jig should sit solidly with the feet resting on the outfeed table and the knife edge as shown in Figure 9. If the knife is adjusted properly, the knife setting gauge should rest flush across the outfeed table and onto the top edge of the knife. If the knife does not make contact, or if the knife causes the adjusters legs to not seat flush on the out- feed table, the knives need to be adjusted.
