Drilling:
Please read and be sure to understand the drill motor instruction manual!
Turn on the water tap or switch on the vacuum cleaner.
(There must at least be sufficient water pressure (max. 4 bar!) to move the arising drilling
mud from the borehole)
Release the locking device (7) on the feed gear and use the hand wheel (8) to turn the drill
downward to the desired drill depth.
Switch off the motor and crank back until the drill bit is completely visible.

Care and maintenance
Upkeep, servicing and maintenance work must only be carried out when the system is at a
standstill.
The best maintenance measures involve the daily removal of sludge, dust and dirt. Special
attention must be paid to the guide column and sliding guide as well as to the gear rack and the
feed bevel. The spindle should be oiled lightly each time it is cleaned.
The sliding guides should be checked for play at regular intervals and re-adjusted if necessary.
Do not grease the drill column and gear rack as the grease takes effect as a grinding
paste together with the adherent dirt and increases wear.
Clean the adjusting screws on the base plate every day and keep them free-moving.
Important! All maintenance, overhauling and repair work must only be carried out by trained
specialised staff
