Distar DDR Operation Manual page 16

Make sure that there is no free play of tool-spindle unit of the equipment, special re-
ducing socket for coolant supply inwards of the drill (not included in the complete drill), and
the connecting condition of jaw members in the chuck of your equipment. When connected,
all three jaw members shall be at the same level. The presence of free play of the tool-spindle
unit of the equipment or the improper connection of the of jaw members in the chuck can
cause circular run-out, which can affect the negative working capacity of the drill, as well as
lead to its destruction, which is extremely dangerous!
Mount the drill on the equipment or on a special adapter (not included in the drill kit),
which allows the cooling liquid to be fed inside the drill. Secure the drill by using wrenches,
which are included in the electric equipment kit, or standard open wrenches (depending on
the type of drill mounting or for the manual angle grinder).
Perform a dry-run test without load for at least 30 seconds. Make sure that there are
no vibrations, circle run-out or butt beats, and any unwanted sounds when running without
load. In case of a large release beat, use the key to free the chuck, screw jaw members at the
maximum diameter, rotate the drill at 120 degrees and repeat the drill mounting procedure.
When mounting the drill on a manual angle grinder, repeat the drill mounting procedure. In
case of a repetition of the above-mentioned deviations, make a diagnostic of your equipment
or diamond drill.
Attention! Diamond drill bits of DDR, DDS types and L=50-80 mm (DIAMOND AN-
NULAR DRILL BITS (САМК), DIAMOND SEGMENTED DRILL BITS (САМС), L=50-80 mm)
must be operated with a continuous supply of liquid coolant! You should use the equip-
ment, which is authorized to work with liquid coolant and with the ability of rotation speed
regulation!
USE:
Attention! Turn your electrical equipment into an in drilling shear mode, before drilling!
Important! Stop drilling procedure and further drilling should be performed in the drill-
ing shear mode (without perforation)! Failure to comply with this requirement can lead to the
Table 3.
