4.2.2) Using the drilling machine with the support trolley (Ref. to Fig. 6).
– Insert the spigot (30) of the drill into the housing of the trolley (see Fig. 3).
– Follow the instructions in § 7 and allow the machine to "warm up" for 2 minutes prior to com-
mencement of work.
– Using the main handle on the drilling machine, move the trolley over the sleeper to the desired
hole position and locate the guard end piece TPM into the bush of the chair.
Note: For use of the support trolley, refer to specific "Service and Maintenance Manual".
4.3) Drilling
The auger starts to rotate only when the engine is fully revved: rev the engine gradually and then
operate a slight starting pressure on the machine so that the bit tip catches and starts drilling the
wood with the automatic advancement, without additional force from the operator. When the pre-
set drilling depth is reached, the adjustment device (26) prevents any further advancement; at this
stage, release the accelerator (08) and the return springs (25) will automatically retract the machine.
4.4) Emergency release
Correct operation of the machine and its safe and rapid release of the augers, in
case of need, are guaranteed only by using CEMBRE original PV range augers.
To remove the machine during a drilling operation, proceed as follows:
4.4.1) Machine equipped with "MND" spindle
– Immediately release the accelerator.
– Operate the emergency lever (12) moving it downwards.
– Keeping the lever depressed, slightly twist the machine, to release the auger. Lift and remove the
machine from the auger.
4.4.2) Machine equipped with "MND1" spindle
– Immediately release the accelerator.
– Operate the emergency lever (12) which immediately releases the auger from the machine. Lift
and remove the machine from the auger.
5. REPLACING THE SPINDLE
For augers having a Ø 16 mm shank, the "MND1" spindle must be interchanged with the standard
"MND" spindle.
Replace the spindle as follows:
(See Fig. 1 and 2)
