The adjustable fence will cut joints at angles from 0 to 90 at
a xed cut height of 9mm (5/16") (the center of a 25.4mm
board). To utilize the adjustable fence (4), remove the xed
fence by loosening the height lock knob and rotating the
height adjustment knob until the xed fence comes clear
of the top of the joiner fence. Loosen the angle lock knob
(11) and move the adjustable fence to the desired angle
and re-tighten the knob. When using the adjustable fence
for 90 degree cuts. it is recommended that you verify the
angle of cut with a measuring tool such as a combination
square or other device. Angle cuts of other degrees should
also be vered with additional measuring tools.
Plunge Depth Adjustment (Fig. 3)
The depth of cut can be set to match the dimensions of the
particular size biscuit you use. The numbers on the depth
selector (6) coincide with the three most common sizes
of biscuits, 0-10-20. The letter "M" stands for maximum
depth capacity of the tool (18 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.
Use your biscuit joiner only for the purposes listed
below:
Cutting and jointing of timber
Edge jointing long boards of either natural wood or
manufactured sheeting
APPLICATIONS
Page 3
The Biscuit Jointer is designed for the cutting and jointing
of timber. It provides an accurate, effective and convenient
alternative to the other means of jointing (such as doweling)
and can be particularly useful for edge jointing long boards
of either natural wood or manufactured sheeting.
The 100mm (4") TCT 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 (12 mm wide), #10 (10 mm wide) and #0 (8
mm wide). Glue is applied and the biscuit inserted into
the semicircular slot that is 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, two biscuits can be used, one above the
other, for extra strength.
FEATURES
Before making any adjustments, unplug the tool.
Fence Adjustments (Fig. 1~2)
The joiner comes with two fence options. The joiner comes
with the xed fence (3) attached. This allows cuts at 90
degrees to a cut height of a maximum of 35mm (1-3/8").
To adjust the cut height. loosen the height lock knob (5)
and rotate the height adjustment knob (10) to achieve the
desired cut height. Tighten the height lock knob rmly using
nger pressure only.

Making a Normal Biscuit Cut (Fig. 6~7)
Position your work pieces together and draw a reference
mark at 90o to the center point of each proposed joint
location. Space the joints about 4 inches apart.
Separate your work material and clamp each piece securely
to a stable work bench or work table.
Set the biscuit depth selector (6) to correspond with the size
of biscuit you are using. Generally #20 biscuits suit most
applications. If you are using stock that is 16mm thick or
less, you will need smaller biscuits.
Adjust the height of the fence as required and if using the
xed fence rmly tighten height lock knob (5) using nger
pressure only. If using the adjustable fence rmly tighten
angle lock knob (11).
Place one hand on the handle (2) and the other hand on
the motor housing (12).
Place the cutting guide at the center point of each slot in
turn and press the fence against the edge of the work piece
(see gure 6). Make sure the jointer fence is ush to both
sides of your work surface.
Switch on the power switch and push the motor housing
towards the work material. Once the cut is made pull the
motor housing back and allow the return spring to retract the
blade from the slot. Turn the power switch off. Repeat the
procedure until all slots are cut in your work piece.
Cut the slots in the matching piece of work material,
again lining up the center point of each slot and to make
the cuts.
Once all the cuts are complete dry t your biscuits into
your joints and test t your materials to ensure proper
alignment.
Remove the biscuits and insert glue into the slots using a
nozzle applicator or thin wood scrap. It is also helpful to
apply a small amount of glue to the biscuits themselves
before inserting them into the slot.
Place the biscuits in position and clamp your work materials
together until the joint line becomes invisible. Keep your
work materials clamped until the biscuits swell and the
glue sets.
It is possible that thick pieces of timber may require two biscuits
at each location, one at a height of about 1/3 the thickness of
the wood, and the other at about 2/3 the tickness.
NOTE: Unlike other saws and drills, mastering the biscuit joiner
does take some practice. Remember that the ultimate goal is
to achieve a parallel set of cuts in your work surface. If you
nd yourself making uneven cuts, you are probably working
too fast. Make sure of these points:
When the tool powers on it might vibrate out of position.
Prior to making a cut make sure the center of the tool is
aligned with the center of your cut mak.
Make sure the height lock knob is rmly tightened.
Go slow - visually make sure you have the joiner lined up
with your cut mark and most importantly that the fence is
ush with both the top and side edge or your work material
prior to making the cut. Once these are accomplished then
make the cut. Patience and practice are the keys to creating
perfect joints.
OPERATION
ADJUSTMENTS
Fine Depth Adjustment (Fig. 4)
All biscuits are manufactured to slightly different sizes, so
you might need to adjust the depth of cut on the tool. The
depth adjustment rod (7) can be rotated to increase or
decrease the depth of cut.
Biscuit jointers 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 utilizing the various features of
the Biscuit Joiner you can create a wide range of different types
of joints. Always make a reference line to line up the machine
with the center of the material to be plunged to ensure accurate
biscuit placement (Figure. 5 - Please note in the picture the
center of the adjustable fence is omitted in order to better
explain the joining process).

MAINTENANCE
Replacing the blade
Pull out the power plug.
Remove the xed fence and raise the adjustable fence to
the o degree position.
Turn the machine over and unscrew the two screws in the
base plate. Pivot the base plate open.(see Fig. 8)
Now, with the arbor lock (8) in the top of the gearbox housing
depressed, rotate the blade by hand until the blade locks.
Loosen the blade ange anti-clockwise using the pin wrench
supplied.(see Fig. 9)
Remove the outer blade ange.
Remove the blade leaving the inner ange in place.
Mount the new blade, insert the outer blade ange and
fasten.
Important: The cutting bevel of the teeth (i.e. the direction
of rotation of the saw blade) has to conform to the direction
of the arrow marked on the housing.
Make sure the blade lock is released.
Important: After replacing the blade, make sure the blade
runs freely by turning the saw head by hand.
Close the base and re-install the two screws.
Before using the machine again, check that the safety
devices are in good working order.
Plug the machine into a main socket outlet and run the
machine without actually cutting any work material. This is
to make sure the blade is spinning freely.

Dust Extraction (Fig. 10)
You can use the dust bag provided or with the aid of the
adaptor accessory, connect the tool to a vacuum system.
The plastic dust extraction assembly ts in the dust port (9)
on the joiner. You can then attach a vacuum hose or the
supplied dust bag, to the adaptor.
Please note, when the bag becomes full, the dust will back-
up into the adaptor and the dust port. To clean them, turn off
and unplug the tool and remove the packed dust.
Maintenance
Do not allow brake uid, gasoline, and other petroleum
base products come in contact with the plastic parts of the
joiner. They contain chemicals that can damage, weaken
or destroy the housing of the tool and thus compromising
the integrity of the double insulation.
Keep the machine's air vents unclogged and clean at all
times. Remove dust and dirt regularly from the machine.
Cleaning is best done with compressed air or a rag. Re-
lubricate all exposed moving parts at regular intervals.
