Supply

• Diamond drill rig with turnstile, allen key and operating instructions in a cardboard box.

Application for Intended Purpose

• The diamond drill rig BST 90 V is made for diamond core drills with a collar diameter from 53mm .
• The max. drilling diameter for the BST 90 must not exceed 102 mm and with vacuumset must not exceed 42mm.
• In case of wrong handling or misuse, the producer does not assume any liability.

Use

After each readjustment always check that the screws are tightly fixed so that safe operating of the drill rig is possible.

Mounting the turnstile

• Mount the turnstile (1) on the right or left side of the carriage (2) depending on the work to be performed.
• Check whether the turnstile (1) is fixed tightly

Fastening of the Drill Rig

• Fastening on the floor by means of vacuum

• Don’t use the vacuum mounting on the wall and overhead!

• For a low-pressure mounting the surface where the base is mounted must be not porous and must be flat and free of cracks.

• If this is not the case, this kind of mounting can’t be used. For the vacuum mounting you need a vacuum pump and a vacuum hoses (see illustration).

• These items are available on request.

• Connect the drill rig an the vacuum pump by means of a vacuum hose.

• Get the drill rig in the correct position and switch on the pump.

• Make sure, that all four levelling screws in the foot plate are turned back and that a low pressure of -0,8 bar is reached.

• By means of pressing the valve button in the handle the drill stand can be unburdened (vacuum is escaping) and can be readjusted.

• The vacuum pump must run during the whole working time and must be placed so that one can see the manometer.

• Make sure that the drill stand is fixed firmly before you start drilling!

Fastening by means of dowels in concrete
To mount the drill stand by means of dowels it is necessary to remove the vacuum grip and the base gasket from the base plate.

• Loosen and remove the fastening nut.
• Remove the vacuum grip and the gasket of the base plate.
• For brickwork, Brickwork- Dowels must be used
• Mark the position of the drill holes for the fastening on the surface to be drilled.
• Drill a hole (Ø 16) 50 mm deep (A), into which the dowel M12 (B) is to be placed; insert and secure the dowel with the doweling tool (C).
• Install the drill rig.
• Fix the washer (E) and finally the fastening nut (F) on the quick action clamping screw (D).
• Tighten the fastening nut (F) with a wrench SW 27.
• Before and after tightening the nut (F), the 4 adjustable screws have to be adjusted in order to adapt the rig to the surface.
• Do check whether the drill rig is installed safely and firmly.

Fixing the Core Drill Motor

Wear protective gloves!
Caution! When mounting the machine, risk of squashing.

• Move the machine holder (2) upwards until the locking pin (5) locks in the column.
• Remove both Allen screws M8 (3) and take off the clamp (4).
• Put the core drill (M) on the carriage and close the clamp (4) by means of the Allen screws (3).

Drill Bit Changing

Attention!
The machine is heavy and when you use or sharpen it, it might heat up enormously. You could burn your hands or get cut or ripped by the segments. Before the beginning of all works on the tool you have to disconnect the plug from the mains. Always use protective gloves when changing the drill bit.

• The drill spindle has a right-hand thread.
• To hold on spindle always use an jaw wrench SW 32.
• Never remove the drill bit with impacts because this way the machine will be damaged.
• With some waterproof grease, which is put on the drill bit thread, and a copper ring between spindle and drill bit you can remove the drill bit easier.

Water Connection

If the drill bit is not cooled enough with water, the diamond segments could heat up and consequently get damaged and weakened. For this reason, always make sure that the cooling system is not blocked. In order to supply the machine with water, please proceed as follows:

• Connect the tool to the water supply system or a water pressure vessel using the GARDENA connector.
• Always make sure that the machine only runs with enough clear water as the seals get damaged when the machine is running dry.
• Attention! The maximum water pressure should not exceed 3 bar!
• Make sure that the segments are well cooled. If the drilling water is clear, the segments are well cooled.
• Overhead-drilling only with water collection ring.
• In case of frost warning, drain the water system.

Operations

In order to operate the tool safely, please observe the following notes:
Details of the work area

• Keep the work area free of everything which could obstruct operations.
• Provide for adequate illumination of the work area.
• Adhere to the regulations concerning the power connection.
• Lay the power cable in such a way that any damage by the drill can be avoided.
• Make sure to always keep the work area in view and to be able to reach all necessary operating elements and safety installations.
• Keep other persons away from your work area in order to avoid accidents.

Space requirements for operating and maintenance
Whenever possible, keep a free space for operating and maintenance of about 2 m around the drill position, so that you can work safely and have immediate access in case of a failure.

Drilling

• Loosen both Allen screws with the enclosed wrench . Position the column in the appropriate angle
• Tighten both screws again.
• At the beginning, drill very slowly, since the drill bit does only starts cutting with a fraction of the cut surface in the material.
• If you drill too fast or with too much pressure, the drill bit could get jammed.

Demounting the Core Drill Unit

• Move the machine holder with the core drill upwards until it locks in the final position.
• Remove the drill bit.
• Loosen the wing screw
• While doing so, hold the drill rig firmly!
• Remove the drill rig.
• Unscrew the quick action clamping screw

Care and Maintenance

• Always keep the drill rig clean, especially the column with the toothing and the 4 sliding pieces in the machine holder.
• In order to allow the free movement of the pinion shaft, it should be slightly lubricated.
• In order to achieve a good performance of the drill rig, the 4 sliding pieces in the machine holder have to move along the column without slackness.
• After having drilled 10 holes you should check if the sliding pieces have got loose-fitting due to drilling vibration.
• If the position should have changed, it can be readjusted as follows:
• Loosen the counter nut on the Allen screw by means of an jaw wrench SW 17
• Adjust the Allen screws and the position of the thrust piece to the column by means of a hex head wrench SW 8.
• Tighten the counter nut again and check whether the carriage moves easily on the column.

In case of malfunctions

• Switch the motor off and disconnect it from the power. Repairs of the electrical parts may only be performed by an authorized service specialist.
