WATER SUPPLY
CARE AND MAINTENANCE
The MK-2000P is equipped with an intake cooling water flow control valve that can be placed vertically
of horizontally. A quick disconnect is supplied with the unit for ease of operation.
Water flow enters through the flow control valve and exits directly through the center of the motor shaft.
Cooling flow may be adjusted using the cooling water flow control valve.
Clean the MK-2000P following use.
Do not allow particles or parts to penetrate inside the tool.
The carbon motor brushes require inspection by a qualified maintenance technician after 300 hours of
operation. If the brushes are shorter than .2 inches (5 mm), they must be replaced.
During inspection of the motor brushes, the motor commutator must also be inspected. In case of ir-
regular coloring or scratches, the commutator must be repaired by a qualified service center.
After replacement, the motor brushes must be run at an idle for 20 minutes.
The MK-2000P requires inspection and gearbox cleaning by a qualified service center after 500 hours
of operation.
Do not operate with water pressure greater than 43.5 PSI (3 Bars).
CAUTION
In case of overload, a continuous acoustic warning signal will sound.
When the Acoustic Overload Warning is heard, it is recommended that the operating speed and ap-
plied pressure be immediately reduced, and /or, the core bit be operated under a no-load condition.
If the MK-2000P stops due to the activation of one of the overload protective devices, this
should not be considered an equipment failure.
