3. ACCESSORIES TO BE ORDERED SEPARATELY 3.1) DBG-F2 device (*) with moving arm for clamping the drill to the rail web and track fittings, complete with the following end pieces: – TDB 6: standard end piece for rails and stock rails. – TDB 1: for switch blades and compound frogs. – TDB 3: for repairing (adjusting) existing holes on rails for subsequent application of electrical connections and for additional special applications. 11 10 (*) Always supplied with type LD-41P drill.
3.3) Templates for positioning the drill on rails and stock rails to enable drilling to be carried out according to the provisions of railway board standards: 13.2.5) Engine oil change (Ref. to Figs.
3.8) Broach cutters Every year or 100 hours of operation 13.2.3) Spark plug cleaning (Ref. to Fig. 30) – Using a 4 mm allen key remove the fixing screw on the top of the red cover. – Disconnect the spark plug wire lead and remove the spark plug with the key supplied. Inspect the spark plug. Replace it if damaged or badly fouled, if the sealing washer is in poor condition, or if the electrode is worn. Measure the spark plug electrode gap, correct the gap if necessary by carefully bending the side electrode.

13.1.2) Removal of metal residues from the crankcase When the drill is positioned as shown in Fig. 26 unscrew the cap with magnetic insert (28) on which any metal residues present in the oil will have collected. Carefully clean the magnetic insert with a clean cloth and screw it back into the appropriate housing. FIG. 26 – REMOVAL OF METAL RESIDUES 4.
● The drill is equipped with a coolant attachment valve (35) and a vent valve (17) which are located as shown (Fig. 3). If under certain operating circumstances they need to be interchanged, proceed as follows: – Using a 17 mm hexagonal spanner unscrew the vent valve from its seat. – Using the 4 mm allen key provided with the drill, remove the appropriate coolant valve from its seat and fit into the vent valve seat. – Fit the vent valve into the vacant coolant valve seat.
12. STORING THE DRILL 5. SPINDLE ADVANCE LEVER When work has been completed, put away the drill by proceeding as follows: 12.1) Depressurise the tank of the SR5000 cooling unit (see § 4), close the tap (02) on the tube from the tank, and disconnect the quick-coupling (03). 12.2) Carefully clean the drill, particularly in the spindle area, removing machining waste (swarf, etc.) and any deposits of lubricating coolant. 12.3) Fully withdraw the spindle.
11. STARTING THE ENGINE 6. PREPARING THE DRILL STOP THE ENGINE when servicing the drill: before removing the broach cutters, spiral bits, positioning templates etc. 6.1) Assembling broach cutters (Ref. to Figs. 8-11). 6.1.1) Insert the guide bit in the cutter from the side of the spigot. 6.1.
6.2.2) Insert into the spindle shaft, the DPE spacer required to activate the coolant system. If it necessary to use an APE... adaptor, the bit must first be fitted into the corresponding APE adaptor and locked with the appropriate grub screw, then the DPE spacer inserted. Note: Adaptors type APED… (e.g. APED 135/165) do not require use of DPE spacer. 6.2.3) Insert the bit-spacer unit in the spindle shaft so that the two engaging dogs on the bit spigot line up with the grub screws.
02 For clarity the drill is not shown in the figures 7. DRILL TYPE LD-41P Part code LD-41P consist of the LD-41PN basic drill (see page 1) complete with the DBG-F2 moving arm device for clamping to the rail web and track fittings (Ref. to Fig. 12).
9.2) Drilling in line with rail heads (Ref. to Figs. 23-24) 9.2.1) Fit the MPAF... positioning template corresponding to the rail to be drilled (see § 7.3 or 9.1). 9.2.2) Fit the MRF clamp on the head of the rail, keeping it in contact with the rail head at the reference point of the drilling centres. Lock it in position with the lever. The lever is provided with a return pushbutton for moving in any direction after locking. (See Fig. 23) 9.2.3) Insert the SPA...

Approach Start drilling with discharge of lubrocoolant Drilling Finish drilling with removal of swarf and switching off of lubrocoolant FIG. 19 – COOLANT DRILLING WITH BROACH CUTTER 8.3) Drill fitted with special spiral bit Follow the sequence described in § 8.1, taking care to position the drill on the rail by keeping the spindle fully withdrawn.
8. DRILLING Check engine oil level before operation (see § 13.2.4). Switch on the cooling system before starting the drill (see § 4). 8.1) Drill fitted with “short” type broach cutter (for drilling thicknesses of up to 25 mm). The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1), clamping end piece (§ 7.1), positioning template (§ 7.3), the drill being clamped to the rail (§ 7.4), as follows: 8.1.
