AUXILIARY HANDLE
Tighten the auxiliary handle (8) on journal (4) of the drill. The
depth gauge (7) can be used for fixing the depth of the drilled
bores.
REMOVING THE CHUCK
For keyed chuck drills:
Open the jaws of chuck (2) completely, and by means a
screwdriver unwind the left-threaded securing screw. Fix
the drill spindle with an open end spanner.
Put the special key for chuck tightening in one of the
three bores and rotate the chuck anti-clockwise, using
the chuck key as a lever, to unscrew chuck (2) from the
drill spindle.
For keyless-chuck drills:
Grip rear collar of keyless chuck (2) and rotate front collar
until chuck is opened. By means a screwdriver unwind
the left-treaded securing screw. Insert and fasten Allen
key or screwdriver bit into the chuck.
Clamp the place for fixing the spindle (3) by means of a
spanner and rotate the chuck anti-clockwise by the free
end of the key (bit).
RECOMMENDATIONS FOR OPERATION
Apply moderate pressure during drilling in concrete (ap-
proximately 80–100 N). Higher pressure will not increase
drilling efficiency, but it will lead to decreasing the op-
eration life of the machine. Drill at speed lower than the
maximum speed and select the speed depending on the
processed material.
Use carbide tipped straight shank drill bits. Take the drill
out of the opening from time to time to remove dust.
Watch out the stage of blunting of the bit and replace it if
considerable decrease of efficiency is observed.
Before drilling large-diameter holes in metal, wood or
plastics, drill a small pilot hole.
The optimum capacity when drilling in concrete is up to 8
mm, and the possible capacity is up to 13 mm.
