Supply

• Diamond drill rig with turnstile, Allen wrench SW 6 and SW 8, 4 Allen screws M 8 x 25 and operating instructions in a cardboard box.

Application for Intended Purpose

• The diamond drill rig is made for diamond core drills which are fixed by means of a mounting plate. The max. drilling diameter must not exceed the drilling diameter indicated in the chart.
• 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

• Fastening by means of dowels in concrete
• 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).
• Screw the quick action clamping screw (D) into the dowel.
• 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 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 a 4 Allen screws M8x20. The mounting plate is put on the drill motor with the fitting key and fixed by means of the 4 screws.
• Pay attention to the mounting direction.
• Insert the core drill with the attached mounting plate into the drill rig and lock it with the turnstile (see picture above).
• For the operation of the core drill, its operating instructions and safety advices have to be strictly observed!

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

Inclined drilling

• Remove the bolt, which holds the column at a 90° angle, from the foot plate.
• Loosen both Allen screws M10 with the enclosed wrench SW 8. Position the column in the appropriate angle and tighten both screws again.
• After drilling put the column back in the 90°position and lock it with the screw.
• BST 300: Furthermore, loosen the locking lever on the bracing.
• The scale on the toothed column makes adjusting the drilling angle easier.
• 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.
• In order to reach the max. drilling depth, you probably have to use an extension for the drill bit!

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 fastening nut (F)
• While doing so, hold the drill rig firmly!
• emove the drill rig.
• Unscrew the quick action clamping screw (D) (see page 12).

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. 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 SW17
• Adjust the Allen screws and the position of the thrust piece to the column by means of a hex head wrench.
• Tighten the counter nut again and check whether the carriage moves easily on the column.
