Step 6:
Adjust Fence Assembly
Using the fence is the safest and most accurate method of jointing,
and should always be used when work permits.
The fence tilts forward and backward to 45 degrees. It has a
90-degree stop, 135-degree stop, and 45-degree stop.
Lock handle
and tilt handle.
To tilt the fence forward:
1. Loosen the lock handle.
2. Use the tilt handle to tilt the fence forward. Lift up slightly on the
fence while tilting to prevent scratching of the table surface.
3. Tighten the lock handle.
To tilt the fence backward:
1. Loosen the lock handle.
2. Pivot the stop block out of the way.
3. Use the tilt handle to tilt the fence forward. Lift up slightly on the
fence while tilting to prevent scratching of the table surface.
4. Tighten the lock handle.
To move the fence forward or back:
1. Loosen the lock handle.
2. Rotate the handwheel counterclockwise to move the fence
forward. Rotate the handwheel clockwise to move the fence
back.
3. Tighten the lock handle.
To check and adjust the 90-degree stop:
1. Loosen the lock handle.
2. Tilt the fence until the stop screw contacts the stop block.
3. Place a square or machinist’s protractor (not provided) on the
table and against the fence surface.
4. If the angle is not 90 degrees, loosen the hex nut on the stop
screw.
5. Turn the stop screw until the fence is flush with the square.
6. Tighten the hex nut.
7. Tighten the lock handle.
To check and adjust the 45-degree stop:
1. Loosen the lock handle.
2. Tilt the fence until it contacts the 45-degree stop.
3. Place a square or machinist’s protractor set (not provided) at
45 degrees on the table and against the fence surface.
4. If the angle is not 45 degrees, loosen the hex nut on the stop
screw.
5. Turn the stop screw until the fence is flush with the protractor.
6. Tighten the hex nut.
7. Tighten the lock handle.
Step 7: Adjust Cutter Guard Tension (For Swing-Away Guard Only)
Set the cutter guard tension so that:
• The guard conceals the unused part of the cutterhead
• After the workpiece clears the cutterhead, the guard swings
back to contact the fence
To adjust:
1. Loosen the tension knob.
2. Push the knob to the right to increase tension; turn to the left to
decrease tension.
3. Tighten the knob.
Step 8: Feed the Workpiece Through the Jointer
WaRninG
Do not attempt to operate the machine if you are not completely
familiar with its operation. Obtain immediate advice from a
supervisor, instructor, or other qualified personnel.
Use of this machine requires that you give your work your undivided
attention, and careless acts or not paying close attention to work
being performed may result in serious injury to yourself and/or
others. Never operate this or any machine under the influence of
drugs, alcohol, or any medication that may impair judgment.
Dust created by manufacturing activities may be harmful to your
health. Your risks from exposure may vary. Always work in a well-
ventilated area and wear safety approved, protective dust masks
specifically designed to filter out microscopic particles. Utilize wood
dust collection systems appropriate to your machine type.
Avoid Kickback
It is very important that each workpiece be carefully inspected for
stock condition and grain orientation before running through the
machine. “Pull-out” and the dangerous kicked back material can
result when the workpiece has knots, holes, or foreign materials
such as nails. Kickback can also occur when the material is fed
against the grain on the cutterhead.
