paper contacts the housing wall (See C.2). Lift up the clamp lever
and move it to the lever lock position. Press the sanding paper around

the base plate shape as tight as possible and fix the end under the
other sanding paper clamp. Check the sanding paper is square to the
baseplate .If not correct., remove and refit it again . Always, ensure
the sanding paper is tight over the baseplate and secured underneath
both locked clamps. This will ensure safe and efficient sanding
performance.

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 C.3).
7 PAPER PUNCH
If using sanding paper without dust holes, use the paper punch to
perforate the holes to ensure correct dust extraction. Position the
punch (10) over the baseplate with the punch sides on the edges of
the baseplate (See D). Press the punch into the baseplate to punch
holes into the sanding paper. Then remove the punch and check all
the holes have been formed correctly.

performance always empty the dust bag in time. Open the zip and
