Consumption of the lubrocoolant depends both on the variable degree of opening of the tap (02) and the inner pressure of the tank: it is therefore advisable to open the tap a little when the tank is at maximum pressure, while it must be fully opened when the pressure in the tank is low.

5. SPINDLE ADVANCE LEVER The spindle is advanced by moving the lever (36) (See Fig. 6 a). The lever is fitted with a release pawl (39) which, when pressed, renders it independent of the hub and hence the spindle; the operator can therefore easily vary the angular position of the lever without movement of the spindle (Fig.6). - Page 12 6.

The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1), clamping end piece (§...
- Page 19 8.1.4) Start the engine, following instructions § 11. 8.1.5) Proceed to drill by initially applying light pressure on the lever (36), increasing the pressure progressively, avoiding jolts, and finally relieving the pressure in the exit phase. When drilling close to raised markings on the rail the initial pressure must be extremely light until the markings disappear, otherwise the cutter may be damaged.

- Page 24 - To avoid an electric shock, do not touch spark plug, plug cap or spark plug lead during engine running. The LD-41P drilling machine features a 4-stroke petrol engine run on unleaded regular grade petrol only. Pump octane rating 86 or higher.
- Page 25 11. STARTING THE ENGINE Before starting the engine, ensure that: - the spindle shaft is fully retracted. - the accelerator control lever is positioned at the low speed position "0". 11.1) Set the engine "ON/OFF" switch to the "ON" position (Fig.
- Page 26 12.4) Place the drill and the SR5000 cooling unit in a sealed place free from dust, moisture and the risk of accidental impact. For better protection Cembre recommends the use of the VAL P24 plastic case or VAL P24-CS (variant with folding handle and wheels, see Fig. 24a) designed for this purpose (see § 3.2). The DBG-F2 moving arm device allows the drill to be housed and locked in the case.
- Page 27 13. MAINTENANCE Before you service or remove parts, stop the engine and allow it to cool. Always remove the spark plug cap from spark plug when servicing the engine to prevent accidental starting. After the first 10 operating hours, proceed with sump oil change, as follows: (Ref.
- Page 28 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.
