Handling - Rothenberger RODIADRILL Ceramic Instructions D'utilisation

 Operate the water flow to the bore crown and borehole location manually using the control
valve (5).
Optional: External water supply
 Set the valve (4) to "0" to shut down the water supply from the water tank.
 Remove the sealing plug (6) and connect the water hose (optional, No. FF35301).
Attention! Check the seal on the water hose connection!
Water supply RODIADRILL Ceramic ECO
The water supply is by means of a quick plug-in coupling, as an option with a No. FF35026 wa-
ter pressure tank or No. FF35302 water connecting hose on Gardena.

Handling

 Set the suitable speed using the gear change (7) rotary switch (s. technical data).
 Hold the equipment firmly by the hand grip (12). Use the other hand to guide the neck at the
front of the equipment under the valve block.
Be sure without fail to take up a firm position. Do not stand on ladders or
other moving items!
 Use the switch (8) to switch on the equipment (with "acceleration" function) and accelerate
immediately to maximum speed.
 Apply the bore crown and start drilling using consistent pressure. Use of the optional No.
FF35750 spot drill aid is recommended at the face of the borehole.
 RODIADRILL Ceramic: Briefly operate the water supply valve.
RODIADRILL Ceramic ECO: Turn on the water connection.
 Continue drilling using slight follow-up pressure and in the process consistently impulse-
press the water supply valve.
Attention! No dust formation should be visible!
 Relieve the crown at intervals and retract slightly (oscillating movement) in order to flush out
the drilling mud.
Use continuous flushing when changing over from drilling tiles or natural stone to drilling the
subjacent carrier stone in order to keep the drill as free from drilling mud as possible.
Notes on achieving optimum drill results
 A continuous water supply to the drill bit is preferred in order to keep drilling cores and drill-
ing core scraps from collecting.
In case the bore crown is blocked by drilling core remains all the same or the water flow rate is
impaired by drilling mud, the borehole must be pierced in the crown with the assistance of a
suitable aid (drilling core pusher or suitable wire).
 Immediately remove any possible drilling cores and drilling core remains from the bore
crown each time after drilling before this becomes caked together.
 Only use clean water (tap water) to fill the pressure tank.
Attention! Relieve the tank pressure first!
 Only use diamond drill bits that have been tested by ROTHENBERGER.
To some extent, commercially available diamond bore crowns from third-party manufacturers
feature excessive true-running inaccuracy. Problems arise for this reason when starting up on
damageable surfaces and in addition to these precision boreholes are not possible.
