OPERATION & ADjUSTMENTS
Adjusting the blade square with the fence
The machine has been set up with the blade parallel to the fence. Please check that
during shipping this has not changed. With the power cord disconnected from the power
outlet, check that the blade moves freely and that all of the fence functions and controls
are operating correctly. Find a square edge on a scrap piece of wood and with the biscuit
depth control set to M (maximum) and the fence set to 90
the distance from the top of the square edge down to the top of the right hand side of the
slot cut. Measure again to the left side. These measurements should be identical. If not the
fence can be adjusted by loosening the two screws situated at the front of the machine just
above and to the side of the blade and just above the two Grippers (refer to fig 1). When
these are loosened, move the fence down or up the side that requires the adjustment, try
to keep the block as close to parallel to the base plate Re-tighten the screws and take
another cut ensuring that the blade now cuts parallel to the fence. When finished, if the
blade block protrudes over the base plate and you require the two to be parallel, undo the
four base plate screws and pack insulation tape to the side that needs raising. For most
operations these two parts do not require to be perfectly parallel together so this is not
necessary.
Grippers
biscuit joiners tend to pull to the left when making a cut. Grippers have been provided to
reduce this effect. When making some joints, you may wish to retract the grippers so as
not to scratch your workpiece. To prevent scratching, rotate the grippers approximately 1/4
of a turn and push them back behind the front plate.
NOTE: One gripper turns to the right and the other to the left.
Adjusting the fence for square
To adjust the fence for square, first loosen the pointer screw (Refer to fig 1.) and hold a
square between the fence and the front of the unit. Place the indicator against the stop on
the 90-degree end of the angle scale and retighten the screw. When the angle indicator is
against the stop, the pointer should indicate 90 degrees.
bottom plate
For certain applications, you will want to use the bottom plate for alignment. In these cases,
the adjustable fence should be set to 0
is used primarily when making butt joints. The distance between the centreline of the blade
and the bottom plate is fixed at 9.5 mm which allows centring on 19 mm thick stock.

OPERATION & ADjUSTMENTS
Operation
biscuit joiners can be used for making
various types of strong, accurate joints in
pieces of timber or wood sheeting.
To cut the biscuit slot the body of the
jointer is moved toward the material after
alignment, by utilising the various features
of the 8306 you can create a wide range of
different types of joints.
Always make a reference line to line up
the machine with the centre of the material
to be plunged to ensure accurate biscuit
placement.
Making a normal biscuit or plate joint
1. Position the mating pieces together and draw a reference mark at 90
point of each proposed joint location. Space the joints about 100 mm apart.
2. Set the plunge depth to the biscuits you are using. Generally, #20 biscuits suit most
applications. If you are using stock that is 15 mm thick or less, you will need smaller
biscuits.
3. Adjust the height of the blade as required.
4. Place the cutting guide at the centre point of each slot in turn and press the fence
against the edge of the workpiece.
5. Switch on and plunge the blade to make the cut.
6. Allow the return spring to retract the blade from the slot and then switch off.
7. To cut a slot in the edge of the matching workpiece, place this piece on a flat surface
and lay the jointer on its side (piece of wood).
8. Again line up the centre point of each slot and make the cuts.
9. Insert glue into the slots using a nozzle applicator or thin wood scrap.
10. Place the biscuit in position and clamp the joint until the biscuit swells and the glue
sets. NOTE: It is possible that thick pieces of timber may require two biscuits at each
location, one at a height of about 1/3rd the thickness of the wood, and the other at
about 2/3rd the thickness.
