General & Electrical Safety
• In the event of a malfunction or breakdown, grounding provides a path of least resistance
for the electric current to reduce the risk of electric shock. This tool is equipped with an
electric cord with an equipment-grounding conductor and a grounding plug.
• The plug must be plugged into a matching outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
• Do not modify the plug provided – if it will not fit the outlet, have the proper outlet installed
by a qualified electrician.
• Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. The conductor with green insulation - with or without yellow stripes - is the
equipment-grounding conductor.
• If repair or replacement of the electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
• Check with a qualified electrician or service personnel if the grounding instructions are not
clear, or if in doubt as to whether the tool is properly grounded.
• Use only 3-wire extension cords with 3-prong grounding plugs and 3-pole receptacles that
accept the tool’s plug.
• Repair or replace damaged or worn cord immediately.
1. KEEP GUARDS IN PLACE and in working order.
2. REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of checking to see that keys and
adjusting wrenches are removed from the tool before switching it on.
3. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
4. DON’T USE IN DANGEROUS ENVIRONMENTS. Don’t use power tools in damp or wet
locations, or expose them to rain. Keep work area well illuminated.
5. KEEP CHILDREN AWAY. All visitors should be kept a safe distance from work area.
6. MAKE THE WORKSHOP CHILD-PROOF with padlocks, master switches, or by removing
starter keys.
7. DON’T FORCE THE TOOL. It will perform more efficiently and safely when working at the rate
for which it was designed.
8. USE THE CORRECT TOOL. Don’t force the tool or attachment to perform a task for which it
was not designed.
9. USE THE CORRECT EXTENSION CORD. Make sure the extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage, resulting in loss
of power and overheating. The table below shows the correct size to use depending on
cord length and the nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
10. WEAR CORRECT APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or
other jewelry which may get caught in moving parts. Non-slip footwear is recommended.
Wear protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use a face or dust mask if the cutting operation is
dusty. Everyday eyeglasses only have impact-resistant lenses; they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold work when practical. It is safer than using
hands and also it frees both hands to operate tool.
13. DON’T OVERREACH. Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance.
Follow instructions for lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing, and when changing accessories, such as blades,
bits, cutters etc.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in ‘off’ position
before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended
accessories. The use of incorrect accessories may create a risk of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is
damaged should be carefully checked to determine that it will operate properly and perform
its intended function. Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions that may affect its operation. A guard
or other part that is damaged should be properly repaired or replaced.
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of
the blade or cutter only.
21. NEVER LEAVE THE TOOL RUNNING UNATTENDED. SWITCH THE POWER OFF. Do not leave
the tool unattended until it comes to a complete stop.
Sanding Tool Safety
WARNING!
• Hold the power tool by insulated handles or gripping surfaces only, because the sanding
belt/sheet 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.
• Use clamps or another practical way to secure the workpiece to a stable platform.
Holding the workpiece by hand or against the body makes it unstable and may lead to
loss of control.
• Recommendation that the tool always be supplied via a Residual Current Device with a
rated residual current of 30mA or less.
• If the replacement of the supply cord is necessary, this has to be done by the manufacturer
or his agent in order to avoid a safety hazard.
a) ALWAYS wear appropriate protective equipment, including a dust mask with a
minimum FFP2 rating, eye protection and ear defenders
b) Ensure all people in the vicinity of the work area are also equipped with suitable
personal protective equipment
c) Take special care when sanding some woods (such as beech, oak, mahogany and
teak). The dust produced is toxic and can cause extreme reactions
d) NEVER use to process any materials containing asbestos. Consult qualified professional,
if you are uncertain whether an object contains asbestos
e) DO NOT sand magnesium or alloys containing a high percentage of magnesium
f) Be aware of paint finishes or treatments that may have been applied to the material
that is being sanded. Many treatments can create dust that is toxic, or otherwise harmful.
If working on a building constructed prior to 1960, there is an increased chance of
encountering lead-based paints
g) The dust produced when sanding lead-based paints is particularly hazardous to
children, pregnant women, and people with high blood pressure. DO NOT allow these
people near to the work area, even if wearing appropriate personal protective equipment
h) Whenever possible, use a vacuum dust extraction system to control dust and waste
i) Be especially careful when using a machine for both wood and metal sanding.
Sparks from metal can easily ignite wood dust. ALWAYS clean your machine thoroughly
to reduce the risk of fire
j) Empty the dust bag or container (where applicable) frequently during use, before
taking breaks and after completion of sanding. Dust may be an explosion hazard. DO
NOT throw sanding dust into an open fire. Spontaneous combustion may occur when oil or
water particles come into contact with dust particles. Dispose of waste materials carefully
and in accordance with local laws and regulations.
k) Work surfaces and sandpaper can become very hot during use. If there is evidence of
burning (smoke or ash) from the work surface, stop and allow the material to cool. DO NOT
touch work surface or sandpaper until they have had time to cool
l) DO NOT touch the moving sandpaper
m) ALWAYS switch off before you put the sander down
n) DO NOT use for wet sanding. Liquids entering the motor housing can cause severe
electric shocks
o) ALWAYS unplug the sander from the mains power supply before changing or
replacing sandpaper
p) Even when this tool is used as prescribed it is not possible to eliminate all residual
risk factors. If you are in any doubt as to safe use of this tool, do not use it

Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features
and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool
Before Use
WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.
Selecting the right grade of sanding disc
• Sanding discs are available in a variety of different grades: coarse (80 grit), medium
(120 grit), and fine (220 grit)
• Use a coarse grit to sand down rough finishes, medium grit to smooth the work, and fine
grit to finish off
• Always use good quality sanding discs to maximise the quality of the finished task
• It is advisable to do a trial run on a scrap piece of material to determine the optimum
grades of sandpaper for a particular job. If there are still marks on your work after
sanding, try either going back to a coarser grade and sanding the marks out before
recommencing with the original choice of grit, or try using a new piece of sandpaper to
eliminate the unwanted marks before going on to a finer grit and finishing the job
Fitting a sanding disc
WARNING: Always ensure the tool is switched off and the plug is removed from the power
point before fitting or removing sanding discs.
Note: Do not continue to use worn, torn or heavily clogged sanding discs. Ensure foreign
objects, such as nails and screws, are removed from the workpiece before starting to sand.
WARNING: Do not use a sanding disc on wood that has previously been used on metal. This
may cause scouring on the wooden surface.
1. Remove any dust or debris from the Hook & Loop Backing Pad (1) before fitting a sanding
disc (9)
2. Match the holes in a suitable disc with the holes in the base (A)
3. Press the disc to the base to attach it
4. To remove the disc, peel it away from the Hook & Loop Backing Pad
Note: To avoid damage and maximise the life of the Hook & Loop Backing Pad, peel the
sanding disc off slowly rather than rapidly removing it.
WARNING: If using sandpaper discs instead of mesh sanding discs, take care to regularly
clean out the build-up of dust on the base underneath the sanding disc and do not let the
disc wear completely down before replacing it. Failure to observe these two precautionary
measure can lead to damage to the hooks and loops on the base, and the sanding disc will
not attach properly.
WARNING: Never use the sander unless the entire base is covered by the sanding disc.
Note: The supplied mesh sanding discs are washable for reuse. Allow to dry completely
before re-using.
Dust extraction
WARNING: Always connect the sander to a suitable vacuum cleaner or workshop dust
extraction system if the sanding dust contains harmful substances, such as particles from old
paint, varnish, surface coatings, etc. Always dispose of harmful dust according to laws and
regulations.
WARNING: Take special care to guard against harmful and toxic dusts when sanding leadbased painted surfaces, woods and metals, particularly if you are unsure about the exact
substances involved. All persons entering the work area must wear a mask specially designed
for protection against the toxic dust and fumes involved. Children and pregnant women MUST
NOT enter the work area. DO NOT eat, drink or smoke in the work area.
• This sander is designed to be connected to a household vacuum cleaner hose or workshop
dust extraction system. This is the preferred and most effective method of dust extraction
• Connect a suitable vacuum hose to the Rotatable Dust Extraction Port (7) and use the
supplied Dust Extraction Port Adaptor (11) if required
• If no vacuum dust extraction system is available, the supplied Dust Bag (5) must be
used (B)
• Attach the Dust Bag to the Rotatable Dust Extraction Port of the sander by pushing the
fitting securely on to the port
• To rotate the Rotatable Dust Extraction Port, grip the port and the Handle (3) then rotate the
port to the desired angle, which can be rotated a full 360°
Note: For optimum dust extraction, remove and empty the Dust Bag when it is no more than
half full.
WARNING: When sanding metal, DO NOT use the dust bag! Hot metal particles and sparks
could ignite residual wood dust, or cause the Dust Bag to catch fire. Always connect the sander
to a suitable workshop dust extraction system when sanding metal. Always clean the tool
THOROUGHLY when switching from sanding wood to sanding metal, and vice versa.
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection,
and suitable gloves when working with this tool.
WARNING: Do not touch the moving Sanding Disc (9)
Note: Always use clamps to secure your workpiece to the workbench wherever possible.
WARNING: NEVER allow the sandpaper to completely wear down before replacing it. Failure
to observe these precautionary measures can lead to damage to the hook and loop surfaces,
resulting in sanding discs failing to attach properly.
Switching ON & OFF
WARNING: Never switch the sander on when the base is in contact with the workpiece or
any other surface. This might cause the operator to lose control over the machine and lead
to serious injury.
1. Connect the power cord to the mains power supply
2. To switch the sander on, push the ON/OFF Switch (2) to the ‘I’ position
3. To switch the sander off, push the ON/OFF Switch (2) to the ‘O’ position

Adjusting the speed
WARNING: Never fit any accessories to the Hook & Loop Backing Pad (1) that are not
rated to the maximum no load speed of this device (see ‘Specification’).
• This Triton sander features variable speed control that enables it to be used with a variety
of accessories, and to work on a range of different materials, workpieces, and objects
Note: The Speed Adjustment Dial (4) can be adjusted when the sander is ON or OFF. When
the Speed Adjustment Dial is set to ‘1’ the no load speed of the sander will be 7000min-1;
when the Speed Adjustment Dial is set to ‘6’ the maximum no load speed of 12,000min-1
will be achieved.
• To adjust the speed, rotate the Speed Adjustment Dial to the desired setting (C)
• The speed settings range from 1–6, with ‘1’ being the lowest speed setting and ‘6’ being
the highest speed setting
• If in doubt about choosing the correct speed setting suitable for the task, begin with a low
speed, examine the results, then adjust to a higher setting if necessary
Sanding tips
• If the tool is connected to a vacuum dust extraction system, switch the extraction device
‘ON’ before switching on the sander
• Clamp workpieces to a workbench wherever possible. Ensure that workpieces cannot
move during work
• Move the tool in circular motions over the workpiece’s surface, applying an even,
moderate pressure until the desired surface finish is achieved
WARNING: Excessive pressure does not lead to a faster removal of material; however, it will
lead to premature wear of the sanding disc, and may cause damage to the tool. Sanding
performance and quality of finish are affected primarily by the choice of sanding disc.
• If there are still scratches on the workpiece after sanding, refer to ‘Selecting the right
grade of sanding disc’
Sanding metal
WARNING: Some additional precautions have to be taken when sanding metal.
• ALWAYS connect the sander via a suitable RCD
• ALWAYS connect the sander to a suitable workshop dust extraction system
• Clean the tool thoroughly before using it to sand metal
WARNING: Hot metal particles and sparks could ignite residual wood dust. ALWAYS clean
the tool thoroughly when switching from sanding wood to sanding metal, and vice versa.
• A sanding disc that was previously used for sanding metal should not be used on
wood again. Residual metal particles may lead to scratches, and damage the
workpiece’s surface
