BELT GUARD
Use two M8*12 hex bolt install the belt guard
to the jointer base casting. Do not over tighten.
WARNING: DO NOT attempt any step of
assembly, adjustments, or maintenance while
your jointer is running. Ensure that the witch
is off, power is disconnected and moving parts
have stopped before making adjustments. Fail-
ure to comply may result in serious personal
injury.
ADJUSTMENTS
TABLE GIBS
WARNING: 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.
The function of the gibs is to allow precise
adjustment of the table movement along the
dovetail ways. Adjustment of the gib will dic-
tate how easy it will be to move the tables up
and down with the hand wheels.
To adjust gibs:
1. Unscrew the upper
and lower check nuts
on the infeed table
several turns, leaving
the lock handle tight.
See Figure 5.
2. Loosen the table lock handle and adjust
the upper and lower gib setscrews until table
movement is smooth and controlled.
3. Once the gib has been properly adjusted,
tighten check nuts and repeat Steps 1-2 for the
outfeed table.
4. Make sure there is no side-to-side movement
of the tables once the check nuts have been
tightened. If there is, repeat Steps 1-4.
KNIVES
WARNING: These knives are extremely
sharp. Never grab the cutterhead directly to ro-
tate it. Always use the drive pulley. Always be
sure the jointer is disconnected from its power
source before you make any adjustments. Seri-
ous personal injury may occur.
KNIFE INSPECTION
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 planning results. The knives are set at the
factory using jackscrews or springs before ship-
ping. Now is a good time to double-check the
knife settings.
To inspect and adjust knife:
1. Unplug the jointer!
2. Remove the upper cover or cutterhead
guard to expose the top of the cutterhead.
3. Carefully turn the cutterhead (using the pul-
ley) until the first knife is at top dead center.
4. Using the knife set-
ting gauge, check the
knife height. The jig
should sit solidly with
both feet on the cut-
terhead. See Figure 6.
If the knife is adjusted
properly; the contact
point at the center of
each adjuster should just touch the tip of the
knife.
If the knife does not make contact, or if the
knife causes the adjuster's legs to not seat on
the cutterhead, the knives need to be adjusted.
CAUTION: Remember, jointer knives are ex-
tremely sharp. Use care when handling during
removing or installing.
ADJUSTMENTS USING JACK SCREWS
When using jack screws, it is not necessary to
install the springs. The knives are locked into
the cutterhead with wedge-type gibs and gib
bolts. Jackscrews under the knives allow fine-
tuning to help in the setting process. To realign
the knives:
1. Unplug the jointer!
2. Loosen the gib bolts until the knife is loose in
the slot. The gib bolts turn clockwise to loosen
and counterclockwise to tighten (when facing
the head of the bolt). See Figure 7 and 7B.
