Maintenance - SPARKY Professional BR2 12E Instrucciones De Uso

▪ For maximum performance use carbide-tipped ma-
sonry impact bits when drilling holes in brick, tile, con-
crete etc.
▪ Turn the speed selector (3) to position "2", then rotate
the torque collar to the drill position.
▪ Apply light pressure and medium speed for best re-
sults in brick.
▪ Apply additional pressure and high speed for hard ma-
terials such as concrete.
▪ When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure.
Drilling wood
▪ For maximum performance, use high speed steel
bits for wood drilling.
▪ Ensure that the torque adjustment collar (2) is at
position "drill bit".
▪ Begin drilling at a very low speed to prevent the
bit from slipping off the starting point. Increase the
speed as the drill bites into the material.
▪ When drilling through holes, place a block of wood
behind the work piece to prevent ragged or splintered
edges on the back side of the hole.
All drilling operations
▪ Use only sharp drill bits.
▪ Mark off the centre of the hole using a centre punch
or nail.
SCREWING / UNSCREWING
Select the appropriate torque by placing one of the
numbers, marked on the torque adjustment collar (2),
against the arrow on the tool body.
Insert the necessary bit.
WARNING: Over-tightening can result in the
screw breaking or damage to the end of the driver bit.
WARNING: If the machine is held at an angle
to the screw being tightened, the head of the screw
may be damaged, or the specified torque may not be
transmitted to the screw. Always keep the machine
and the screw being tightened in a straight line.
CHUCK REPLACEMENT
Chuck removal
WARNING: Always wear eye protection.
Turn the torque adjustment collar (2) to the "drill bit"
position and select low gear, on the speed selector
switch (3). Tighten the chuck around the shorter end of
a hex key (not supplied) of 5 mm or greater size. Using a
wooden mallet or similar object, strike the longer end in
the clockwise direction. This will loosen the left-thread-
ed screw inside the chuck.
Original instructions
1. Open chuck jaws fully.
2. Insert a 5 mm hex key into front of chuck between
jaws to engage screw head. Remove screw by turn-
ing clockwise.
3. Place the hex key in chuck and tighten. Using a
wooden mallet or similar object, strike key sharply
in the anti-clockwise direction. This will loosen the
chuck so that it can be unscrewed by hand.
Chuck installation
1. Screw the chuck on by hand as far as it will go and
insert screw (left-threaded).
2. Tighten the chuck around the shorter end of hex key
(not supplied) strike the longer end in the clockwise
direction with a wooden mallet.
3. Remove the hex key and open the jaws fully. Tighten
the screw in the centre of the chuck with the hex key
in an anti-clockwise direction.
ACCESSORIES
Charger, two Ni-Cd battery packs and two double-ended
screwdriver bits.
