SECTION 5: ADJUSTMENTS
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.
KnivesGeneral
Always lock the table
with the table lock
before using the jointer.
If this step is not
observed, the table
could slide down while
the jointer is operating.
Serious personal injury
may occur.
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.
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
!
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Wear safety glasses
during the entire adjust-
ment process. Failure
to comply may result in
serious personal injury.
The Model G9953 is supplied with a 4 knife
cutterhead, while the Models G9859/60/61
have 3 knife cutterheads.
