the housing wall (see B). Lift up the clamp
lever (4) and move it to the lever lock position.

Always, ensure the sandpaper is tight over
the base-plate and secured underneath both
locked clamps (3).This will ensure safe and
efficient sanding performance.
4. CHANGING HOOK & LOOP SANDING
PAPER
The sanding paper and baseplate are provided
with a hook and loop attachment system to
allow quick and easy changing of the sanding
and polishing accessories. Remove any dust
or other objects from the hook and loop on
the baseplate and sanding paper. Position the
sanding paper evenly on the baseplate and
firmly press down to attach them together. If
the sanding paperhas dust extraction holes
you must align these with the holes in the
baseplate, otherwise the dust extraction will
not function.To remove the sanding paper lift
one corner of the paper and pull it off from the
baseplate (See B.2).
5.PAPER PUNCH
If using sanding paper without dust holes, use
the paper punch (7) to perforate the holes to
ensure correct dust extraction. Position the
punch over the base-plate (8) with the punch

sides on the edges of the base-plate (see C).
Press the punch into the base-plate to punch
holes into the sanding paper.Then remove
the punch and check all the holes have been
formed correctly.
6. DUST BAG
Always operate your sander with the dust bag
fitted. For the best performance always empty
the dust bag in time. Open the zip and empty
the dust from the bag.To remove the bag
,slide the mounting bracket out and away from
the sander ( (See D). To refit the bag, firmly
push the mounting bracket into the location
on the sander housing (See E).
For best performance always empty the dust
bag when it is half full.
7. FLUSH SANDING FACILITY
Your sander can sand flush on three sides of
the base-plate which allows easy access to
corners and edges of moulding (see F).
8. ORBITAL SANDING
Your sander operates in small circular
rotations which allows efficient material
removal.
Operate your sander in long sweeping
movements across your workpiece and even
across the grain. For a finer finish, always use
a fine grain sandpaper and only move the
sander in the direction of the grain and never
across the grain.
Do not allow your sander to remain in the
same position otherwise you will remove
material and create and uneven surface.
WORK HINTS FOR YOUR
PALM SANDER
If your power tool becomes too hot, run no
load for 2-3 minutes to cool the motor.
Always ensure the work-piece is firmly held or
clamped to prevent movement.
Any movement of the material may affect the
quality of the sanding finish.
Start your sander before sanding and turn off
only after stopping sanding. For best results
sand wood in the direction of the grit.
Do not start sanding without sandpaper fitted.
Do not allow the sandpaper to wear away, it
will damage the base-plate.The guarantee
does not cover base-plate wear and tear.
Use coarse grit paper to sand rough surfaces,
