Technical Characteristics

Available special accessories:

Supply
Diamond drill rig with axle, turnstile, allen key and operating instruction in a cardboard box.

Application for Indented Purpose
The diamond drill rig BST 352 V is made for diamond core drills which are fixed by means of a mounting plate (e.g.: EBM 352). The max. drilling diameter must not exceed 352 mm. When drilling overhead, a water collecting device must be used. 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

Hole centering indicator:
The drill rig is fitted with a hole centering indicator for easy and precise positioning.

Mark the center of the hole to be drilled. Fully extend the hole centering indicator (see fig.). Position the drill rig in such a way that the tip of the indicator points precisely to the hole center mark. After the drill rig has been fastened, put the hole center indicator back in its original position.

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.

• 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).
• Screw the quick action clamping screw (D) into the dowel.

  For brickwork, Brickwork-Dowels must be used (drill hole – Ø 20mm).

• 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.

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, a vacuum hoses and the vacuum set BST 352 (see illustration). These items are available on request.

Fitting the vacuum set

Position the coupling plate of the vacuum set on the drill rig base as shown. Turn the knob 90° into the diagonal setting. This locks the coupling plate into the base. Check that the coupling plate is secure. Place the foam rubber seal into the recess on the bottom of the base

Please ensure that the levelling screw is adjusted so that it does not protrude from  the bottom of the base, since otherwise the vacuum will be affected and the rigmay come loose from the mounting surface. When connecting the vacuum onto a sufficiently powerful vacuum (min. – 0.8 bar). make sure that the seals are not worn out

Connect the drill rig and the vacuum pump by means of a vacuum hose. Get the drill rig in the correct position, open the valve on the coupling plate and switch on the pump

**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!

** To unfasten the vacuum connection, close the valve. This opens a bleed valve through which the vacuum can escape. Thus the rig can be activated if necessary when the vacuum pump is running.

Fastening by means of quick action bracing unit

**In order to brace the drill rig by means of the quick action bracing unit, the distance to the opposite wall must be between 1.7 m and 3 m.

Position the drill rig. Position the quick action bracing unit as close as possible behind the support on the base of the rig. Fix the drill rig by turning the crank (G) clockwise. Secure in position by means of the appropriate bolt (H).**

Attention!
It is important that the drill rig is firmly connected to the surface. If not fixed correctly, injuries to the operator or damages to the drilling unit may be caused. Uncontrolled movements during drilling will cause the drill bit to hit the surface to be drilled which may lead to a chipping of the segments. The drill bit might also tilt in the bore hole which consequently will damage it.

Fixing the Core Drill Motor

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

**

Setting up the mounting plate

Move the machine holder upwards until it locks in the top position.
Use the turnstile to open the locking device of the mounting plate.
Remove it and connect it to the core drill motor as described subsequently.
The tool is supplied with a mounting plate, a 10 mm fitting key and 4 Allen screws M8x20.

The mounting plate is put on in such a way with the fitting key on the machine that the socket is in the mounting plate on the same side as the gear switch of the machine. Afterwards the four screws are insert and tightened firmly.

Insert the core drill with the attached mounting plate into the drill rig and lock it with the turnstile.

For the operation of the core drill, its operating instructions and safety advices have to be strictly observed!

Unlocking the carriage:

To unlock the carriage (1) pull out the lock knob (2).
To lock the carriage move the carriage until the locking shaft passes the hole in the column and jumps into place.

Always lock the carriage when the assembly is not in use.

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

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.

**Angled drilling

**

• Remove the screw (1), which locks the pillar at 90°.
• Loosen the two side screws (2) on the base plate if necessary.
• Loosen the clamp (3) on the support with the help of the feed lever.
• Now turn the column until the desired angle.
• Tighten the 2 screws (2) and the clamp (3) again.

The scale on the toothed column makes adjusting the drilling angle easier.

Drilling with Water

If you are cooling the drill bit with water a water collection ring is recommended. This will be mounted with a latch fastener on the screws of the base plate and ensures a clean drilling. Mainly for overhead or lateral drilling. (see spezialaccessories ).

Demounting the Core Drill Unit

• Move the machine holder with the core drill upwards until it locks in the final top position.
• Remove the drill bit.
• Loosen the locking of the mounting plate and remove the core drill machine from the drill rig
• Loosen the fastening nut (F)
• While doing so, hold the drill rig firmly!
• Remove the drill rig.
• Unscrew the quick action clamping screw (D)

Care and Maintenance

• Always keep the drill rig clean, especially the column with the too thing and the 4 sliding balls 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 balls in the machine holder have to move along the column without slackness.

Attention!
After every tenth drilling 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 sliding balls 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

Behavior by Malfunction

Turn off the machine by malfunction and disconnect from the electricity network. Operations on the electrical system of the machine can be executed only by a specialist.

Trouble Shooting

19. replace the sliding balls
