SAFETY WARNINGS
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated electric
planer.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which can ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Do not 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.
2. 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.
3. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
4. Do not abuse the cable. Do not use the cable for carrying, pulling or
unplugging the power tool. Keep cable away from heat, oil, sharp edges
or moving parts. Damaged or entangled cables increase the risk of electric
shock.
5. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
6. 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.
WARNING: READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
FAILURE TO FOLLOW THE WARNINGS AND INSTRUCTIONS CAN RESULT IN
ELECTRIC SHOCK, FIRE AND/OR INJURY.

PERSONAL SAFETY
1. 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 can result in personal injury.
2. Use personal protective equipment. Always wear eye and ear protection.
Protective equipment such as dust mask, non-skid safety shoes or hearing
protection used for appropriate conditions will reduce personal injuries. This
machine develops considerable noise when in use. ALWAYS wear Ear
Defenders.
3. Prevent unintentional starting. Ensure the switch is in the off position before
connecting to power source.
4. 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 can
result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. Dress correctly. Do not wear loose clothing or jewelry. Keep your hair, and
clothing away from moving parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and correctly used. Use of dust
collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not let persons
unfamiliar with the power tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that can affect the power
tool's operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.

6. Keep cutting tools sharp and clean. Sharp cutting edges are less likely to
bind and are easier to control.
7. 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.
SERVICING
1. 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.
PLANER SAFETY WARNINGS
1. Always start the planer before the blade is in contact with the workpiece
and let the blade reach full speed. The tool can vibrate or chatter if blade
speed is too slow at beginning of the cut and possibly kickback.
2. Check the workpiece for nails or screws. If there are nails/screws, either
remove or set them well below intended finished surface. Kickback,
damage to the blades and personal injury can result If the planer blades
strike objects like nails.
3. After changing blades, rotate the blade drum to make sure the blades are
not hitting any part of the housing and that the blade locking screws are
tight. Spinning blades could strike the tool housing and damage the
machine as well as causing possible injury.
4. Do not put your fingers or any objects into the shavings exhaust port or
clean out shavings while the tool is running. Contact with blade will cause
injury.
5. Disconnect from the power source if it becomes necessary to remove
woodchips. The blades are hidden from view and you may be cut if the
blade is touched.
6. Do not use dull or damaged blades. Sharp blades must be handled with
care. Damaged blades can snap during use.
7. Regularly check to ensure the ‘Anti-Kickback pawls operate correctly.
8. NEVER plane a piece of wood without the Cutter Guard completely
covering any exposed Cutter Blade
9. ALWAYS ensure the blades are properly secured in the cutter block before
use.

ASSEMBLY AND INSTALLATION
Ensure the planer is located where there is adequate light and a suitable
power supply. If cable a extension is used, ensure it does not trail along the
workshop floor as this could be extremely hazardous.
There must be sufficient room for the workpiece to move through its entire
length.
Similarly, there must be sufficient room so that the operator does not need to
stand in line with the wood during the planing process.
The planer may be used as a mobile
unit, but for greater stability we
recommend it is bolted to a strong,
firm workbench. The dimensions for
the mounting holes are shown:
Alternatively, mount the planer on a
strong piece of plywood of at least
15mm in thickness, with length
550mm and width 380mm minimum.
The plywood platform, with planer
mounted, is then clamped firmly to a
workbench when required.
ATTACHING THE ANGLE FENCE
The peg - ‘A’ locates in the slotted
hole - ‘B’. It may be necessary to
screw the peg down a little in order
for the peg to locate properly.
The Hex. socket head screw with
washers (in the bag of loose parts), is
used to secure the fence to the
table, through slot ‘C’, into threaded
hole ‘D’.
The fence may be set and locked at
any angle. Use a template or angle
gauge if accuracy is required.

OPERATION
PLANING
ENSURE the timber is completely free of nails, screws and staples etc. before
use.
1. Set the depth of cut, using the Depth of Cut Setting Knob - see Fig.1. Turn
anti-clockwise to increase the cutting depth, clockwise to decrease, using
the scale, indicated in Fig. 8, as a reference. For the initial cut, we
recommend a depth of cut of no more than 1mm. The maximum depth of
cut is 2mm.
2. Ensure the fence is at the correct angle - for normal planing, this would be
90 degrees. For other angles, use a template or angle gauge for greater
accuracy.
3. Slide the cutter guard out of the
way and place the workpiece on
the table so that it rests snugly
against the fence, with the lead
edge a short distance from the
cutter, noting that the direction of
feed is right to left, looking from
the front of the machine.
4. Slide the cutter guard up to lightly
touch the workpiece as shown in
Fig.8, thereby completely
covering any exposed cutter. Ensure the guard is as low as possible and the
cutter guard lock knob is tightened.
5. Raise the cover of the ON/OFF switch and press the green ON button,
marked ‘I’, and allow the machine to come up to full speed.

11
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
6. Applying firm downwards pressure and keeping the workpiece against the
fence, proceed to feed the work over the cutter. Do not feed too quickly.
IMPORTANT: When coming to the end of a piece, ALWAYS use the push stick
to finish - see Fig.8. This is an important safety point.
7. To switch OFF, simply press the red
button marked ‘O’ and close the
cover ensuring it is properly
latched.
When finished, remove all shavings
and sawdust from the machine and
surrounding area and dispose of
safely, accumulation of dust and
shavings is a fire hazard and should
not be allowed to build up.
NOTES:
1. In case of emergency, hit the switch cover firmly and quickly. The cover will
latch down and motor will be switched OFF.
2. The ON/OFF switch is a “No Volt Release” type, so that in the event of a
power failure the machine will not restart automatically once the power is
restored.
THICKNESSING
1. Lower the thicknessing table sufficiently for the workpiece to be inserted
beneath the cutter blade, ensuring the blade is at 6 o’clock. Work enters
from the left and exits at the right of the machine.
2. Raise the table until there is slight resistance. i.e. the work just touches the
blade.
3. Withdraw the workpiece, then wind the table upwards - turn clockwise,
using the Raise/Lower table knob, to the appropriate cutting depth, noting
that one turn is equivalent to 3mm. Do not exceed 2mm depth of cut as
this could cause kickback, and/or damage to the components or
overheating of the motor.
NOTE: It is advisable when working with rough or warped wood to make
very small depths of cut to begin with - 1mm should be sufficient.
4. Support the workpiece at the desired height, so that it is horizontal and
feed it into the cutter, from the left hand side of the machine. The rollers will
automatically feed the work past the kick-back pawls and into the cutter
blade. Ensure it is well supported at the outlet side.
DO NOT remove chips or shavings from the table until the machine has
stopped completely and is isolated from the mains supply.

12
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
NOTE:
1. The workpiece should always be 2-3 inches longer than the finished length
as the ends tend to be uneven.
2. The table should be lubricated with wax, frequently to ensure smooth
operation.
RESET BUTTON
The planer is fitted with an thermal overload protector. If the motor stops
running or fails to start.
1. Close the safety switch cover and
allow the motor to cool for five
minutes.
2. Press the reset button.
3. Raise the cover of the ON/OFF
switch and press the green ON
button, marked ‘I’.
MAINTENANCE
Always disconnect the machine from the mains supply before cleaning or
performing maintenance tasks.
This product is designed to operate with minimum of maintenance, however,
as with all power tools, cleanliness is essential in ensuring work is carried out to
a satisfactory standard. Always keep the table free of shavings/dust etc., and
clean the machine thoroughly after use. Use a low pressure air supply to blow
dust from air vents and other parts wherever possible.
Apply a thin film of wax to the table periodically. This will help keep the table
clean and allow the workpiece to slide more easily.
Do not use solvents to clean the machine as this could damage plastic
components.
CUTTING BLADE REMOVAL
Cutter blades will require sharpening or replacing. Care should be taken at all
times when handling them, they are very sharp, even when appearing to be
dull.
Blades must always be fitted as a pair and must be of the same type. Only fit
blades recommended by the Clarke International.

13
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
First, ensure the machine is switched OFF and isolated from the mains supply.
1. Turn the cutter height adjuster so that it registers zero. i.e. turn the knob
clockwise so that the depth of cut, registered on the scale, is zero.
2. Remove the angle fence.
3. Raise the Cutter Guard arm.
4. Turn the cutter block to reveal the four hex. socket head screws securing
the cutter blade, then carefully remove them.
5. Turn the cutter block by 180 degrees and repeat the process.
NOTE: ALWAYS hone/replace cutter blades as a pair.
6. Replace in reverse order, and, using a straight edge, ensure the cutting
edges are level and in line with the table when they are at 12 o’clock - see
Fig.10. Tighten the securing screws taking care not to over-tighten or
damage the hex. sockets.
NOTE: It is recommended that sharpening is done professionally, using a
jig, as blades must be sharpened as a pair to ensure they are
correctly balanced. This avoids the possibility of vibration due to
imbalanced cutters rotating at speed.
PERIODICALLY
• Wipe both the infeed and outfeed rollers with a damp cloth to remove
all traces of contaminants.
• Wax the thicknesser table frequently to ensure a smooth and reliable
feed.
• Inspect the kickback pawls before each operation to ensure they are
intact and working properly. They should hang normally and loosely.
• Remove the front cover - 3 dome head nuts, and lightly oil all pivots,
linkages and bearings with good quality machine oil. Ensure the
enclosure and all components are perfectly clean before replacing the
cover.
