Makita DBM230 Notice Originale page 22

The DBM 230 is a protection class I insulated machine. For protection
purposes the tool may only be operated with a GFCI. Therefore a GFCI-switch
is integrated in the cable for use in a safety plug with ground.
Caution!
- The GFCI safety switch must not be submerged in water.
- Do not use the GFCI switch for switching the tool on/off!
- Before operations check the proper functioning by pushing
the TEST-button.
First, check the correspondence of available voltage and frequency against the
data on the identification plate.
+6 - -10% voltage difference is permitted. Use only three-wire extension cable
with protective conductor and a sufficient cross-section (min. 2,5 mm2).
A cross section which is to small could lead to excessive power loss and to
overheating of the cable and the motor.

Water connection
If the drill bit is not sufficiently cooled with water, the diamond segments could
heat up which will damage and weaken them. Therefore you should always
make sure that the cooling system is not blocked. In order to provide the
drilling tool with water the following steps must be taken:
Plug the tool to the water supply or a water pressure vessel via the
hose fitting.
Ascertain that the tool is only operated with sufficient clean water as
otherwise the seals will get damaged when the tool is running dry.
Caution: Water pressure must not exceed 3 bar.
Make sure that the segments are cooled sufficiently. If the drilling
water is clear, cooling is adequate.
If you want to enlarge a hole which you just drilled, close it in order to
achieve an adequate provision of cooling water.
When working over-head, a water collecting ring must be used.
Drain the water system when temperatures below the freezing point
are prognosticated.
