GENERAL POWER TOOL
SAFETY WARNINGS
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury. Save all warnings
and instructions for future reference. The term "power tool" in the warnings refers to your
mains-operated (corded) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
NOTE The term “residual current device (RCD)” may be replaced by the term “ground fault
circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting
to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
GENERAL POWER TOOL
SAFETY WARNINGS
3) Personal safety continued...
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce dust-
related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool
before making any adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the power tool’s operation. If damaged, have
the power tool repaired before use. Many accidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the power
tool for operations different from those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Jointer Safety Warnings
– Disc cutters must be rated for at least the speed marked on the tool. Disc cutters running
over rated speed can fly apart and cause injury.
– Always use the guard. The guard protects the operator from broken disc cutter fragments
and unintentional contact with the disc cutter.
– Hold power tool by insulated gripping surfaces, because the cutter may contact its own
cord. Cutting a “live” wire may make exposed metal parts of the power tool “live” and could
give the operator an electric shock.

Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood
by the operator that common sense and caution are factors which cannot be built into this
product, but must be supplied by the operator.
Note: Performance of this tool may vary depending on variations in local line voltage.
Extension cord usage may also affect tool performance.
VOLTAGE WARNING
Before connecting the tool to a power source (receptacle, outlet, ect.) be sure the voltage
supplied is the same as that specified on the nameplate of the tool. If one says 120V and
the other says 115V then there will be no complications. Never try to plug a 120V tool into
a 240V outlet, or the other way around. The plug and outlet have completely different
shapes. This is because a power source with a voltage greater than that specified on the
tool can result in SERIOUSINJURY to the user, as well as damage to the tool. If in doubt,
DONOTPLUGINTHETOOL.
EXTENSION CORDS
Your tool has a polarized, two-prong plug. Do not alter the plug in any way. Only use round-
ed jacket extension cords listed by the Underwriters Laboratories (UL). Improper use of
extension cords may cause inefficient operation of your tool which can result in overheat-
ing. Be sure your extension cord is rated to allow sufficient current flow to the motor. If you
are using the tool outdoors, use an extension cord rated for outdoor use (signified by “WA”
on the jacket).
The extension cord must have a minimum wire size depending on the amperage of the tool
and the length of the extension cord. This size is determined by its AWG (American Wire
Gauge) rating. The smaller the gauge, the greater the cable’s capacity. The amount of
cords used does not matter: Total length determines the minimum AWG rating. Every cord
must meet the AWG rating. Use the chart below to determine what AWG rating is required
for your situation. Cord length is rated in feet.

GETTING TO KNOW YOUR TOOL,
OPERATION & ADJUSTMENTS
FIGURE 1
OPERATION & ADJUSTMENTS
Cutting a slot with a biscuit joiner (Fig.1).
The biscuit joiner 4” blade is plunged into the wood to the required depth, which is pre-set
depending on the biscuit to be used. Commonly available biscuits are #20 (24mm wide),
#10 (19mm wide) and #0 (15mm wide). The typical depth of cut should be #20 (12mm
wide), #10 (10mm wide) and #0 (8mm wide). Glue is applied and the biscuit inserted into
the semicircular slot left by the blade. As the glue sets, it expands the biscuit, resulting in
an extremely strong joint. The adjustable fence allows the height and angle of the blade to
be positioned to suit different joint requirements. The depth of cut can be dialed up on the
pre-set control dial, depending on the biscuit to be used. As with dowels, it is much
quicker and a more accurate operation. The biscuit joiner can also be used to create a con-
tinuous groove, the width of which can be increased simply by adjusting the fence up or
down and carrying out several passes.
Adjustable Fence
The height of the fence can be adjusted to let you make biscuit slots at different depths
down from the surface of the workpiece. The adjustable tilt feature allows a full range of
settings from 0 to 900for cutting slots on a mitered edge. To adjust the height, first loosen
the height lock knob and then rotate the adjustment knob until the desired height is
reached. To adjust the angle of tilt, loosen tilt lock knob, align the desired angle of tilt with
the pointer and retighten the tilt lock knob.

OPERATION & ADJUSTMENTS
Plunge depth adjustment of blade
The depth of cut can be set to match the dimensions of the particular size biscuit you
use.The numbers on the depth adjustment dial (0,10,20) coincide with the three most
common sizes of biscuits.The letter ''M" stands for maximum depth capacity of the tool
(approx.14 mm). To select a depth, align the appropriate number with the mark on the tool's
housing. Rotate the depth adjustment dial to the desired position and it ''clicks" into place.
Because of the manufacture of the biscuit, the width of the biscuit can change. The blade
has been made to allow fitment of the largest biscuits in the slot cut. Sometimes you may
need to sort out the correct sizes, or even moisten the biscuits slightly to achieve a tight fit
where required. Glue is applied and the biscuit inserted into the semicircular slot that is left
by the blade, and the biscuit swells taking up any looseness in the joint.
Fine depth adjustment
You can adjust the tool to leave a little looseness in the joint so that you can move it
slightly before the glue sets. To make this adjustment, first raise the adjustable fence to its
uppermost position then insert a screwdriver into the opening. Turn the depth adjustment
screw clockwise for less depth and counter-clockwise for increased depth. Each full turn
causes a change in depth of 1mm. Always check the depth adjustment by first making test
cuts in scrap wood.
To get maximum depth of cut you can set the dial to M and then adjust the same screw so
that the depth rod is completely loosened. This will give an extra depth to approximately
16mm and if joining two pieces of wood together you get a total depth of 32mm allowing
for home made biscuits or strip of wood to be used. Of course you must re-set the depth
for the biscuit sizes after you have finished using your biscuit joiner in this manner.
If the depth rod becomes loose and turns during a cutting operation. Add either a thick
grease or a screw lock to the thread and this will allow adjustment at any time but stops
loosening due to vibration.

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 900, machine a slot. Now measure
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 00and the height setting is unimportant. This surface
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 900to the centre
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.

2. Cut the slots in the end piece.
3. Clamp the matching face piece so that it protrudes above your workbench with a backer
board supporting it from behind.
4. Cut the slot in the face piece.
Cutting a groove
1. To cut a continuous groove, first adjust the jointer for a butt joint.
2. Place the tool at one end of the work, switch on and purge the blade.
3. Feed the tool to the end of the workpiece, wait for the blade to retract and turn switch
off.
Tongue and groove joints
1. You can cut a tongue into the edge of a piece of timber by varying the height of each
pass until the top surface of the tongue is reached and then turning the work over and
repeating the procedure.
