persons with reduced physical, sensory or
mental capabilities, or lack of experience
and knowledge, unless they have
been given supervision or instructions
concerning use of the tool by a person
responsible for their safety.
Children should be supervised to ensure
they do not play with the tool.
GENERAL SAFETY INFORMATION.
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.
Please retain all warnings and instructions
for future reference.
The term “power tool” in the warnings
refers to your mains-operated (corded)
power tool.
ELECTRICAL SAFETY.
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.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
WORK AREA SAFETY.
Keep your work area clean and well lit.
Cluttered or dark areas invite accidents.
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.
Keep bystanders, children and animals
away while operating the power tool.
Distractions can cause you to lose control.
BEFORE USE.
WARNING! Know your Power Tool. Do
not plug the tool into the power source
until you have read and understood the
information in this manual. Learn the
tool’s applications and limitations, as well
as the specific potential hazards related
to this tool, in order to reduce the risk of
electric shock, fire or serious injury.
WARNING! If any part is missing or
damaged, do not plug the tool into the
power source or install any accessory
until the missing or damaged part is
repaired or replaced. Failure to follow this
instruction could result in serious personal
injury.
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.
Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-
skid safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce the risk of personal
injury.
WARNING! Contact with, or inhalation
of, dusts arising from sanding applications
may endanger the health of the operator
and possible bystanders. Wear a dust
mask specifically designed for protection
against dust and fumes and ensure that
persons within or entering the work area
are also protected.
Always wear eye protection. Any power
tool can throw foreign objects into your
eyes and cause permanent eye damage.

WARNING
Please read and understand these Safety Warnings, Safety Symbols and Instructions carefully and retain
for future use
Always wear safety goggles (not glasses)
that comply with ANSI safety standard
Z87.1.
Everyday glasses have only impact-
resistant lenses. They are not safety
glasses.
WARNING! Wearing glasses or goggles
not in compliance with ANSI Z87.1 when
operating this tool could cause serious
injury.
Dress appropriately. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts to prevent them from becoming
caught in the tool.
Remove any adjusting key or wrench
before turning the power tool on. A
wrench or key left attached to a rotating
part of the power tool may result in
personal injury.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure that these are connected and
properly used to reduce dust-related
hazards.
Use clamps, or another practical way,
to secure and support the workpiece
to a stable platform. Holding the work
by hand or against your body leaves it
unstable and may lead to loss of control.
Make sure there are no nails or foreign
objects in the path of the workpiece to be
cut or sanded.
Be aware of hidden hazards, before
sanding into walls, floors or ceilings,
check for the location of wiring and pipes.
Prevent unintentional starting. Ensure
the switch is in the off position before
connecting to the power source and/
or battery pack, picking up or carrying
the tool. Carrying power tools with
your finger on the switch or energising
power tools that are switched on invites
accidents.
POWER TOOL USE AND CARE.
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.
Do not use the power tool if the switch
does not turn it on and off. A power tool
that cannot be controlled with the switch
is dangerous and must be repaired.
Stay alert, watch what you are doing and
use common sense when operating a
power tool.
Hold the power tool by insulated gripping
surfaces when performing an operation
where the sanding accessory may contact
hidden wiring or its own cord. A sanding
accessory contacting a “live” wire may
make exposed metal parts of the power
tool “live” and could give the operator an
electric shock.
Keep hands away from sanding area.
Never reach underneath the work piece
for any reason. Do not insert fingers or
thumb into the vicinity of the blades/
sanding attachments. Do not stabilize the
Power Tool by gripping the shoe.
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.
Do not overreach. Keep proper footing
and balance at all times. This will enable
better control of the power tool in
unexpected situations.
Always switch the tool off and wait for it
to come to a complete standstill before
putting the tool down.
Do not touch the workpiece or the blade

WARNING
Please read and understand these Safety Warnings, Safety Symbols and Instructions carefully and retain
for future use
immediately after operating the tool.
They can become very hot.
STORAGE & MAINTENANCE.
Disconnect the plug from the power
source the power tool before making
any adjustments, changing accessories
or storing. Such preventative safety
measures reduce the risk of starting the
power tool accidentally.
Store idle power tools out of 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.
Maintain the power tool. 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.
Keep sanding tools sharp and clean.
Properly maintained sanding tools with
sharp sanding edges are less likely to
bind and are easier to control.
Keep blades sharp. Dull or damaged
blades may cause the Power Tool to
swerve or stall under pressure. Always use
the appropriate type of blade/sandpaper
for the workpiece material and type of
cut/sander.
When sanding pipe or conduit, make sure
that they are free from water, electrical
wiring, etc.
Never use dull blades in the tool. They
will cut slower, leave rough cuts and
break easily due to added pressure and
excessive heat. They will also overload
the motor and cause premature failure of
the tool.
Have your power tool serviced by a
qualified repair person using identical
replacement parts only to ensure that the
safety of the power tool is maintained.
WARNING! Use only accessories
recommended for this oscillating tool.
Follow the instructions that accompany
the accessories. The use of improper
accessories may result in injury to the
operator or damage the tool.

BENCH MOUNTING
DUST EXTRACTION
If the Spindle Sander is to be used in a permanent
position, it is recommended that you secure it to a
rigid work surface.
Use the holes in the base of the Spindle Sander as a
template to mark and drill four holes in your intended
mounting surface (ie workbench). Secure the Spindle
Sander into position using large bolts, washers and
nuts (not supplied).
If the Spindle Sander is intended to be more portable,
fix a board to the base which can be easily clamped
and removed from various mounting surfaces
If using bolts make sure they are long enough to
penetrate the workbench or board sufficiently for a
secure fix.
NOTE: Use nylon insert lock nuts or spring washers
in the fixings to prevent vibration from loosening the
fixings.
NOTE: Never use bolts that require force to push
through the Bench Mounting Holes as these may
crack the plastic body as will over-tightening the
fixings.
It is recommended that the Spindle Sander is used
with a dust extraction system for a cleaner and safer
work environment.
Attach the hose from the dust extraction system to
the Dust Extraction Port (13) and ensure it is secure.
For greatest efficiency, activate the dust extraction
system before turning on the Spindle Sander.

SELECTING A TABLE INSERT
SELECTING THE RIGHT GRADE
OF SANDING SLEEVE
Failure to use the correct table insert with its
matching sanding sleeve could result in pinched
fingers or the workpiece being pulled down between
the table insert and the sanding sleeve.
The sanding sleeve should fit snugly into the central
cut-out of the table insert.
Use the following chart to help determine the correct
table insert and upper spindle washer to use with
each sanding sleeve.
Sanding Sleeve
Diameter
Table Insert
Size
Upper Spindle
Washer (9) Size
13mm / 1/2” 13mm / 1/2” Small
19mm / 3/4” 19mm / 3/4” Medium
26mm / 1” 26mm / 1” Medium
38mm / 1 1/2” 38mm / 1 1/2” Large
51mm / 2” 51mm / 2 Large
76mm / 3” 76mm / 3” Large
Sanding sleeves are available in a variety of different
• Grades: coarse (80 grit)
• Medium (160 grit)
• Fine (240 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 sleeve 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 sanding
sleeve 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 sanding
sleeve to eliminate the unwanted marks before going
on to a finer grit and finishing the job.

FITTING A SANDING SLEEVE
NOTE: All of the Sanding Sleeves (11), except the smallest
13mm (1/2”) Sanding Sleeve fit over a matching Rubber
Drum (12).
The Smallest Sanding Sleeve fits over the Spindle alone and
uses the Small Washer.
NOTE: Ensure there is no contact between the Sanding
Sleeve and the Table Insert before turning the machine on.
Fit the Lower Spindle Washer (7) over the Spindle (5) with
the grooves facing upwards. Fig 1.
Select the correct Sanding Sleeve for the intended job.
Select the corresponding Rubber Drum, (except when using
the 13mm sanding sleeve).
Select the appropriate Table Insert (10) in accordance with
the table in ‘Selecting a table insert’.
Fit the Table Insert over the Spindle and onto the Table
Ensure the Table Insert is flush with the table. Fig 2.
Fit the Rubber Drum over the Spindle. Fig 3.
Slide the Sanding Sleeve over the Rubber Drum. Fig 4.
Fit the Upper Spindle Washer (9) over the Spindle
Use the large washer with the 75mm (3”), 51mm (2”), and
38mm (1 1/2”) Rubber Drums
Use the medium washer with the 26mm (1”) and 19mm
(3/4”) Rubber Drums. Fig 5.
Use the small washer with the 13mm (1/2”) Sanding Sleeve.
Fig 5.
Fit the Spindle Lock Nut (6) and the Spring Washer on the
Spindle. Tighten the nut just enough to expand the Rubber
Drum against the Sanding Sleeve. Do not over-tighten. Fig 6
When the sanding sleeve is completely worn it is possible to
turn it upside down and maximise its service life by using the
remaining grit.
NOTE: If the sleeve rotates on the drum when switched on,
the Spindle Lock Nut has not been sufficiently tightened to
compress the drum and therefore grip the sleeve.
IMPORTANT: Do not use a sanding sleeve that is too worn.
This can lead to excessive heat build-up and damage the
rubber drum. Damaged rubber drums due to worn sanding
sleeves will not be covered under warranty.
IMPORTANT: When disassembling the upper and lower
Spindle Washers, these may become difficult to remove from
the Rubber Drum.
If this occurs use a blunt edge to remove the Washers.
