for the field of application.

Inserting and changing tools

The chuck of the diamond core drill with G 1/2" external thread is

located on the drilling spindle. Only use suitable and high-quality tools.

Use cutting tools with good cutting properties. When using diamond

core bits, ensure that the diamond segments still protrude sufficiently

from the core bit tube on the inner and outer diameter. Before mounting

the tool, apply a small amount of dry lubricant spray to the mounting

system.

Loosen the clamping ring of the SK suction head and move it to the

rearmost position. Screw the diamond core bit onto the drill spindle

and tighten it with the enclosed open-end wrench.

Gearshift

The machine features a 3-speed-gearbox, which allows the optimum

speed to be set for each drilling diameter. The preselection of the

speed is made at the gear shift lever (7). Never change gears with force

and only when the machine is running down or stopped. If the gear

lever cannot be moved to the desired position when the machine is at a

standstill, briefly touch the pushbutton switch (4) at the same time. The

recommended speeds for each tool are given in the carrying case.

Soft impact

The soft impact can be easily switched on or off using the change lever

(8) located at the bottom of the drill head. The soft impact accelerates

the work progress in hard materials. Concrete and reinforced concrete

should only be drilled with soft impact.

Symbol „drill" on change lever (8) indicates the position drilling without

soft impact

Symbol „hammer" on change lever (8) indicates the position drilling

with soft impact

Operation

Always comply with recognized accident prevention regulations

and the accompanying safety precautions. In case of functional

failure, have the machine inspected by a qualified electrician befo-

re continuing work.

Before starting work unplug the machine at the mains socket. Make

sure that the swivelling side handle (6) is firmly screwed in at the

desired position. Always hold the machine with both hands when

working and maintain a firm stance.

Continuous operation: Press the pushbutton switch (4) and depress

the trigger lock (3) upwards.

Switch off: Briefly press the pushbutton switch (4).

Infinitely adjustable speed: Pilot drilling is made easier by reducing

the speed. Afterwards, work should always be continued at full speed

and thus full power.

The adjusting dial (2) is ergonomically arranged to permit this either

before or during work.

+ = full speed

- = reduced speed

Dry drilling

Generak information

Pilot drilling always without soft impact, with low contact pressure.

If the tool jams, do not attempt to release it by switching the machine

on and off. Switch the machine off immediately and release the tool

by turning it clockwise and counterclockwise with a suitable open-end

wrench. Carefully pull the tool out of the drill hole.

When drilling, the adjusting dial (2) should always be set to full speed.

The speed should only be reduced for pilot drilling or sharpening on the

sharpening plate etc.

Translation of the DIA 303 S original operating instructions

Dust extraction

Dry diamond drilling must always be carried out with dust

extraction. It is necessary that the suction holes around the chuck on

the diamond drill bit are open and that the industrial vacuum cleaner

is attached to the SK suction head. The extraction system not only

enables almost dust-free drilling, but also ensures increased drilling

progress, a longer service life of the diamond core bit and optimum

cooling of the diamond segments. Drilling without dust extraction

damages the diamond segments due to overheating. An industrial

vacuum cleaner with filter cleaning and according to valid directives

(BGIA dust class M) must be used. To achieve a good suction

performance, the industrial vacuum cleaner must be cleaned at regular

intervals.

Hand-held, with centring

Before drilling, a pilot drill hole with drilling dia. 14 mm, by approx.

8 cm deep, must be drilled in the centre of the planned drill hole.

This serves to guide the supplied ZST centring rod, which should be

inserted into the chuck or extension. For pilot drilling with the ZST

centring rod inserted, drill to a depth of approx. 2 cm with the tool,

switch off the machine, remove the ZST centring rod and continue

drilling.

When using the optional SZ quick centring bit, adapted to the tool

length, the pilot drilling is not necessary.

A wooden plate with sawn-in prism in which the core bit is guided can

also serve as a centring aid.

Stand mounted

The machine can be fixed in the BS 160 drill stand (up to max. drilling

range 202 mm) with the mounted side handle (6). For stand mounted

dry drilling, the TBS dry extraction system (optional) must also be

mounted between the chuck and the diamond core bit. This must be

lubricated from time to time with dry lubrication spray.

For easy pilot drilling, attach the optional BS 160-ABH centring aid to

the drill stand (necessary for large diameters).

Drilling

Work with sufficient contact pressure when drilling without soft

impact. If it is too low, the diamonds tend to polish. In this case, the

drilling progress becomes less and less until finally no more material

is removed. This can only be corrected by briefly drilling in the SP

sharpening plate.

Drilling with soft impact

Select moderate contact pressure when drilling with soft impact, let the

core bit „work" in conjunction with the soft impact. Especially as soon

as reinforcement is drilled through in order to reduce vibrations.

Ergonomic work

A holder (1) is located on the power tools switch handle, into which an

auxiliary handle (included in the scope of delivery) can be screwed in.

This ensures a comfortable, back-saving posture when working down-

wards (compressor setting).

Overload indicator

The overload indicator (5) is located at the lower part of the switch

handle and serves to check the machine load. The display of the

different operating modes is done by means of a green LED light.

Functional description

Continuous green light:

Unit switched on and machine load is low to optimum.

Flashing green light, slow:

Machine is overloaded, the contact pressure must be reduced.

Flashing green light, fast:



Machine has reduced speed due to overload. The contact pressure

must be reduced.

Green light went out:

Machine has switched off due to overload and must be switched off

and on again. Alternatively, the machine is not switched on.
