Additional Safety Rules For
Orbital Sanders
m Hold the power tool by insulated
gripping surfaces, when performing
an operation where the cutting
accessory may contact hidden wiring.
Cutting accessory contacting a “live”
wire may make exposed metal parts of
the power tool “live” and could give the
operator an electric shock.
m Do not use accessories which
are not specifically designed
and recommended by the tool
manufacturer. Just because the accessory
can be attached to your power tool, it does
not assure safe operation.
m The rated speed of the accessory
must be at least equal to the
maximum speed marked on the
power tool. Accessories running faster
than their rated speed can break and fly
apart.
m The outside diameter and the
thickness of your accessory must be
within the capacity rating of your

cannot be adequately guarded or controlled.
SAFETY WARNINGS COMMON FOR
SANDING

9
JCB-20OS
Instruction & User Manual
m Do not use a damaged accessory.
Before each use inspect the accessory
such as abrasive wheels for chips
and cracks, backing pad for cracks,
tear or excess wear, wire brush for
loose or cracked wires. If the power
tool or accessory is dropped, inspect
for damage or install an undamaged
accessory.
m After inspecting and installing an
accessory, position yourself and
bystanders away from the plane of
the rotating accessory and run the
power tool at maximum no-load
speed for one minute. Damaged
accessories will normally break apart during
this test time.
Kickback and Related Warnings
m Kickback is a sudden reaction to a pinched
or snagged rotating wheel, backing pad,
brush or any other accessory. Pinching
or snagging causes rapid stalling of the
rotating accessory which in turn causes the
uncontrolled power tool to be forced in
the opposite direction of the accessory’s
rotation at the point of the binding.
m For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of
the wheel that is entering into the pinch
point can dig into the surface of the material,
causing the wheel to climb or kick out. The
wheel may either jump toward or away
from the operator, depending on direction
of the wheel’s movement at the point of
pinching. Abrasive wheels may also break
under these conditions.
m Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below.
m Maintain a firm grip on the power
tool and position your body and
arm to resist kickback forces. Never
place your hand near the rotating
accessory. Accessory may kickback over
your hand.
m Do not position your body in the
area where power tool will move if
kickback occurs. Kickback will propel the
tool in direction opposite to the wheel’s
movement at the point of snagging.
m Use special care when working
corners, sharp edges etc. Avoid
bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and
cause loss of control or kickback.

16 JCB-20OS
Instruction & User Manual
Sanding Surfaces
m Place the machine flat on the workpiece,
ensuring the entire anding disc makes even
contact.
m Power on the sander.
m Apply uniform sanding pressure.
m Adjust your pressure to suit the work as
required.
Less sanding pressure increases the sanding
capacity and protects the machine and the
sanding paper.
NOTE
The removal capacity and the sanding pat-
tern are determined mainly by the selection
of the Sand paper (grade), the speed of the
sanding pad and the application pressure.
NOTE
Rough Sanding
m Attach a sand paper with coarse grain.
m Apply only light sanding pressure to achieve
increased material removal.
For faster material removal, do not increase
pressure on the tool, instead use a coarser
sanding sheet.
NOTE
Fine Sanding
m Attach a sand paper with fine grain.
m With moderate pressure, move the
machine in a circular pattern or alternately
in lengthwise and crosswise directions over
the workpiece.
Do not tilt the machine during operation.
This will apply uneven pressure, and may
cause damage to the work piece (e.g. when
sanding veneer).
NOTE
To avoid marring the finished surface, switch
off the machine, and only lift it from the
workpiece when it has come to a stop.
NOTE
Orbital Sanding
m Guide your sander parallel to the working
surface and move it in circles or in a cross
pattern.
m The speed of the orbital motion of the
sanding pad is reduced as applied pressure
increases.
Selecting The Right Grade Of
Sandpaper
m Use coarse grits to sand down rough
finishes, medium grit to smooth the work
and fine grit to finish off.
m The higher the grade number, the finer the
grit.
m For rough work start with a low grade of
grit. (e.g. 60 grit) and change to a higher,
finer grade (e.g. 120 grit) for finishing.
m If you use a fine grade for rough surfaces the
sandpaper will clog and need changing more
frequently.
The correct grade for your application will
depend on sanding speed, material and pres-
sure applied. Always test on a scrap piece of
material if possible.
