WARNING
2.1 GENERAL WOODWORKING MACHINE SAFE PRACTICES
Exposure to the dust created by power sanding, sawing, grinding, drilling and other
construction activities may cause serious and permanent respiratory or other injury,
including silicosis (a serious lung disease), cancer, and death. Avoid breathing the
dust, and avoid prolonged contact with dust. Some examples of these chemicals are:
q Lead from lead-based paints.
 qCrystalline silica from bricks, cement and other masonry products.
 qArsenic and chromium from chemically-treated timber.
Always operate tool in well ventilated area and provide for proper dust removal. Use
a dust collection system along with an air ltration system whenever possible. Always
use properly tting approved respiratory protection appropriate for the dust expo-
sure, and wash exposed areas with soap and water.
Always wear safety glasses or goggles and protective footwear.
Wear dust masks when required.
Wear hearing protection that is suitable for the level and frequency of the noise you are
exposed to in the woodworking area. If you have trouble hearing someone speak from
one metre away, the noise level from the machine may be hazardous.
Use gloves to protect hands from splinters when handling wood but do not wear them near
rotating blades and other machinery parts where the gloves can catch.
2. IMPORTANT INFORMATION

OPERATION MANUAL
Make sure the guard that is in position is in good working condition, and guards the
machine adequately before operating any equipment or machine. Check and adjust all other
safety devices.
Make sure the equipment is properly grounded before use.
Check that keys and adjusting wrenches are removed from the machine before turning on
the power.
Inspect stock for nails or other materials before cutting, planning, routing or carrying out
similar activities.
Make sure that all machines have start and stop buttons within easy and convenient reach
of an operator. Start buttons should be protected so that accidental contact will not start
machine.
Ensure that all cutting tools and blades are clean, sharp, and in good working order so that
they will cut freely, not forced.
Turn the power o and unplug the power cord (or lock out the power source) before
inspecting, changing, cleaning, adjusting or repairing a blade or a machine.
Use a “push stick” to push material into the cutting area. Jigs are also useful in keeping hands
safe during cutting procedures. Keep hands out of the line of the cutting blade.
Always use a push stick for pieces less than 30 cm (1 ft) in length, or for the last 30 cm of a
longer cut, and to remove the cut piece.
Clamp down and secure all work pieces when drilling or milling.
Use good lighting so that the work piece, cutting blades, and machine controls can be seen
clearly. Position or shade lighting sources so that they do not shine in the operator’s eyes or
cause any glare and reections.
Ensure that the oor space around the equipment is sucient to enable you to machine
the size of work piece being processed safely without bumping into other workers or
equipment.
Woodworking machines should be tted with ecient and well-maintained local exhaust
ventilation systems to remove sawdust or chips that are produced.
Electric power cords should be above head level or in the oor in such a way that they are
not tripping hazards.
Keep work area free of clutter, clean, well swept, and well lit. Spills should be cleaned up
immediately. Floor areas should be level and non-slip. Good housekeeping practices and
workplace design will reduce the number of injuries and accidents from slips, trips, and falls.
Do not wear loose clothing, work gloves, neckties, rings, bracelets or other jewelry that can
become entangled with moving parts. Conne long hair.
Avoid awkward operations and hand positions where a sudden slip could cause your hand
to move into the cutting tool or blade.
Do not remove sawdust or cuttings from the cutting head by hand while a machine is
running. Use a stick or brush when the machine has stopped moving.
Do not use compressed air to remove sawdust, turnings, etc. from machines or clothing.
Do not leave machines running unattended. Do not leave a machine until the power is
turned o and the machine comes to a complete stop.

OPERATION MANUAL
ELECTRICAL REQUIREMENTS
Nominal Voltage.........................................240V
Cycle.............................................................50 Hz
Phase...............................................Single Phase
Power Supply Circuit...........................10 Amps
Full Load Current.................................7.0 Amps
(Full load current rating is also on the specication plate on the motor.)
The full-load current rating is the amperage a machine draws when running at 100% of the out-
put power. Where machines have more than one motor, the full load current is the
amperage drawn by the largest motor or a total of all the motors and electrical devices that
might operate at one time during normal operations.
Full-Load Current Rating for these machine at 240V is 7 Amps
It should be noted that the full-load current is not the maximum amount of amps that the
machine will draw. If the machine is overloaded, it will draw additional amps beyond the
full-load rating and if the machine is overloaded for a long period of time, damage, overheating,
or re may be caused to the motor and circuitry.
This is especially true if connected to an undersized circuit or a long extension lead. To reduce
the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that meets the requirements.
3.4 FULLLOAD CURRENT RATING
Place the machine near an existing power source. Make sure all power cords are protected from
trac, material handling, moisture, chemicals, or other hazards. Make sure there is access to a
means of disconnecting the power source. The electrical circuit must meet the requirements for
240V. To minimize the risk of electrocution, re, or equipment damage, these machines should
be plugged directly into the power socket.
NOTE : The use of an extension cord is not recommended as it may decrease the life of electrical
components on your machine.
3.3 ELECTRICAL INSTALLATION

OPERATION MANUAL
3.5 TEST RUN
Once the assembly is complete, test run your machine to make sure it runs properly and is
ready for regular operation.
The test run consists of verifying that the motor powers up and the machine runs correctly.
When operating correctly, the machine runs smoothly with little or no vibration or rubbing
noises. If, during the test run, you cannot easily locate the source of unusual noise or vibration,
stop using the machine immediately, then review the Troubleshooting section on Page 23.
If you still cannot remedy a problem, contact your distributor
4. OPERATION
4.1 BASIC CONTROLS.
The following descriptions will help you to become
familiar with the basic controls of your machine.
ON/OFF Switch: Starts/stops the spindle and the
drive rollers of the Thicknesser. (Fig. 4.1)
Overload Reset Button: This machine has a motor
thermal overload protection switch, which will trip if
the motor becomes too hot. To reset the switch, move
the ON/OFF switch to OFF, wait a few minutes to allow
the motor to cool, then press the reset button.
Fig. 4.1
on/oFF button
reset button
Height Adjustment Handle: The thicknesser depth of
cut is controlled by using the elevation crank on top of
the machine. Rotating the crank clockwise raises the
cutterhead. (Fig. 4.2)
Fig. 4.2
height aDjustment
Depth of Cut Scale: The Depth Of Cut Scale, located
on the front of the machine, is a convenient way to
quickly determine how much material is being planed
o in one pass. (Fig. 4.3)
1. With the machine OFF, insert your workpiece just
under the depth of cut scale
2. Crank the raising / lowering handle until the button
(B) comes in contact with the workpiece.
3. As you rotate the raising / lowering handle, the
needle on the depth of cut scale will move showing
you how much material will be removed in that
pass under the depth of cut scale.
NOTE: The manual depth gauge can be reset by
adjusting the three xing screws that hold the gauge to
the machine. Fig. 4.3
A
B

16
OPERATION MANUAL
Thickness Scale: The Depth of cut can also be read
directly from the inch/millimeter scale on the front of
the thicknesser, as shown. (Fig. 4.4)
Although the correct depth of cut varies according
to wood hardness and workpiece width, we recom-
mend a maximum depth of cut at full width, of no
more than 1.5mm. A series of light cuts will give a
better end result and put less stress on the motor than
trying to take o too much material in a single pass.
Adjust the depth of cut to make an initial light (0.5mm)
cut.
NOTE: One revolution of the height adjustment
handle is equivalent to approximately1.6mm depth of
cut.
Return Rollers:
Return Rollers assist is sliding the workpiece back to
the operator following the planing operation.
(Fig. 4.5)
Fig. 4.4
Fig. 4.5
4.2 WORKPIECE INSPECTION
Some workpieces are not safe to plane or may require modication before they are safe to pass
through the thicknesser. Before cutting, inspect all workpieces for the following:
• Material Type: This machine is only intended for planing workpieces of natural wood ber.
Attempting to plane workpieces of any other material could lead to serious personal injury
and machine damage.
• Foreign Objects: Inspect lumber for defects and foreign objects (nails, staples, imbedded
gravel, etc,). If you have any question about the quality of your lumber, do not use it.
Remember, wood stacked on a concrete oor can have small pieces of stone or concrete
pressed into the surface.
• Large/Loose Knots: Loose knots can become dislodged during the planing operation.
Large knots can cause kickback and machine damage. Always choose workpieces that do not
have large/loose knots when planing.
• Wet or “Green” Stock: Avoid planing wood with a high water content. Wood with more than
20% moisture content or wood exposed to excessive moisture (such as rain or snow), will plane
poorly and cause excessive wear to the knives and motor. Excess moisture can also hasten rust
and corrosion of the planer and/or individual components.
• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous
to cut because they are unstable and often unpredictable when being planed. DO NOT use
workpieces with these characteristics!

17
OPERATION MANUAL
This section gives you the basic process that happens during an operation with this machine.
Familiarize yourself with this process to better understand the operation of this machine.
To complete a typical operation, the operator should do the following:
1. First check that the workpiece is clean and free of any defects or foreign materials that might
cause kickback or damage the cutters.
2. Adjusts the height of the head for the correct depth of cut.
3. Start the dust collection system.
4. Connect the thicknesser to the power supply and turn the machine ON.
5. Move the workpiece in slowly until the “Height Adjustment Scale” registers
5. The operator should place their body to the side of the machine, then lay the workpiece on
the in-feed table and feed it into the machine until the in-feed roller engages it and moves it
past the cutterhead.
6. When the workpiece exits the thicknesser, return it to the in-feed table, using the return
rollers and make as many passes as necessary.
7. When nished turn the machine OFF.
4.3 BASIC OPERATION
Operating Tips
qWhere ever possible use the full width of the thicknesser cutters. If the width is smaller
than the width of the cutters, alternate the cutting path between the left, the right and the
middle of the table to evenly distribute the wear across the cutters.
qScrape all glue o joined boards before putting the timber through the thicknesser
qONLY machine natural wood. Do not machine wood composites or any other man-made
material.
qMachine the workpiece with the grain. NEVER feed end-cut or end-grained lumber into
your machine.
qKeep the work area clear.
qAlways true up any cupped or warped stock on a jointer or bandsaw before placing it
through the thicknesser.
qWhen making multiple passes through the thicknesser with long stock, use the stock
return rollers on top of the machine to move the material back to the infeed side.
qWhen possible, machine both faces of the workpiece so that they will be parallel with
one another
NOTE: Anytime you switch directions with the cutterhead elevation crank, there will be a small
amount of backlash—the amount the crank moves before the cutterhead begins to move. How-
ever, as long as you move the handle in the same direction during operation, backlash will not
be a factor

18
OPERATION MANUAL
AVOIDING SNIPE
Snipe, gouging or depression of the board at the ends, can occur when the board is not properly
supported. (Fig. 4.6)
For workpieces longer than 1200mm, greater care must be taken to reduce the problem because
the additional length of the workpiece translates into more unsupported weight pulling down
on the end of the board. This unsupported weight will work against keeping the stock at. Make
sure to use supports or stands whenever long pieces are being planed to avoid this problem.
Since snipe occurs at the end of the boards, it is good practice to start with a workpiece that is
slightly longer than what you need so that you can simply cut o the end with the problem.
Fig. 4.6
CHIP MARKS OR INDENTATIONS
Reason: Chip indentation or chip bruising is the result of wood chips not being removed from
around the cutterhead. Instead, they are deposited on the planed surface and crushed into the
workpiece by the outfeed roller. This condition can be caused by a number of reasons, some of
which are:
a. The type of lumber being planed. Certain species have a tendency to chip bruise.
b. A high moisture content (20% or higher) and/or surface moisture. Typically found in air-dried
lumber where the surface is dry but the interior of the stock needs more time to season.
c. Dull knives or inserts
d. Depth of cut too much.
Solution:
a. Lumber must be completely dry, preferably kiln-dried (KD). Air-dried (AD) lumber must be
seasoned properly and have no surface moisture. DO NOT plane partially air-dried (PAD)
lumber.
b. Make sure the planer knives or inserts are sharp.
c. Reduce the depth of cut and make more passes.

19
OPERATION MANUAL
5. MAINTENANCE
5.1 LUBRICATION
The Thicknesser should provide you with a long time of service provided the following
maintenance operations are performed.
1. A quality paste wax should be applied to the table surface to ease the movement of the
workpiece across it. Be sure to bu o all excess wax so that it does not get absorbed into
the wood when planing.
2. Having clean feed rollers is essential for optimal results. After disconnecting the machine
from the power supply, check the feed rollers after each use for buildup of pitch, gum,
or resin and be sure to clean o with a non ammable tar and pitch remover.
3. Any moving parts should be cleaned regularly with a penetrating oil and lubricated with a
light coating of medium weight machine oil.
FEED CHAIN LUBRICATION
To lubricate feed roller chain drive:
1. DISCONNECT THE MACHINE FROM THE POWER!
2. Remove the height adjustment crank handle.
(A in Fig.5.1)
2. Remove the (4) socket head cap screws that secure the
top cover to the four columns. (B in Fig.5.2)
3. Remove the top and the side cover to expose sprockets
and chains (Fig. 5.3)
4. Use mineral spirits, sti brush, and shop rags to clean
any dirt from the chains.
5. Apply a light grade of oil to the chain links and
sprockets.
6. Re-install side cover, the top cover and the height
adjusting crank handle

OPERATION MANUAL
The thicknesser is supplied with bearings that are lubricated and sealed at the factory. These
bearing do not require any further attention unless they need to be replaced. If a bearing fails,
the thicknesser will probably develop a noticeable rumble or vibration, which will increase
when the machine is under load. The bearings are standard sizes and can be replaced.
MAIN BEARINGS
MOTOR BRUSH REPLACEMENT
Brush life will vary depending on the load placed on the
motor. The brushes should be inspected every 10-15
hours of use.
To inspect:
1. DISCONNECT MACHINE FROM THE POWER SUPPLY
2. Remove the Brush Holders, one of which is shown at (A).
The other is located in the same position on the rear
of the motor assembly. The Brush Holder can be
removed using a at blade screwdriver. (Fig. 5.4)
3. Once the brush has been removed, inspect the carbon
(B), the spring (C), and the wire (D).
4. If the carbon of either brush is worn down to 4.5mm or
less, both brushes should be replaced. Also if the spring
or wire are burned or damaged in any way, both
brushes should be replaced. (Fig.5.6)
