Performing the Coplanar Alignment
If alignment is required as determined in the
previous section, proceed as follows:
Disconnect machine from
power source before making
any adjustments. Failure to comply may cause
serious injury.
1. Disconnect power from machine.
2. Unlock
both cabinet lock handles (A
2
).
3. Raise the table (D) fully upright.
Adjustment is performed by means of four
setscrews (B
2
) that adjusts the table pitch and tilt at
the back (towards the fence) and two hex cap
screws (A
1
) that adjusts the table toward the front.
Adjustment can consist of a front adjustment , rear
adjustment or (more probable) a combination of
both.
Rear adjustment
Tools required – 13mm wrench, 4mm hex wrench
1. With a 13mm wrench, loosen three hex cap
screws (B
1
).
2. Using a 4mm hex wrench, make very slight
adjustments of 1/8 to 1/4 turns to four
setscrews (B
2
) as required.
A clockwise turn will raise the table; a
counterclockwise turn will lower the table.
Adjusting the two right setscrews will have
greatest adjustment impact to the table's right
side; adjusting the two left setscrews will have
greatest adjustment impact to the table's left
side.
3. When adjustment is complete, tighten the hex
cap screws (B
1
).
Front adjustment
Tools required – two 13mm wrenches
1. Hold the hex cap screws (A
1
) in place with one
wrench while using the other to loosen the
locking hex nuts.
2. Adjust the screws (A
1
) slightly from 1/8 to 1/4
turn.
A counterclockwise turn will raise the table; a
clockwise turn will lower the table. Adjusting
the right screw will have greatest adjustment
impact to the table's right side; adjusting the
left screws will have greatest adjustment
impact to the table's left side.
3. When adjustment is complete, secure by
tightening the hex nut while maintaining the
position of the screw with the second wrench.
It may be necessary to repeat the exercise in this
Figure 10
section more than once to achieve co-planar
alignment.
Note: If the tables do not lock properly after the
adjustment, see Jointer Table Lock Handle
Adjustment on page 15.
