Product Overview
The machine features a main grip, interface plate for the drill stand, water swivel/suction head, and a multifunction display for real-time data.
Preparations
Ensure the side handle is adjusted and tightened. Secure the drill stand using anchors or a vacuum base plate. If using a vacuum, ensure the pressure gauge remains in the green zone.
Operation
Switch the machine on using the motor on/off switch or the operating button. The multifunction display provides real-time feedback on drilling performance and battery status.
Drilling
The machine supports both wet and dry drilling. For wet drilling, connect the water supply and ensure the water flow regulator is set correctly. For dry drilling, use a dust extraction system if required.
Core Removal
The product includes a core removal function to free a core stuck in the core bit. Activate this via the multifunction display when the machine is ready and the core bit is stationary.
Maintenance
Remove the battery before any maintenance. Clean the chuck and clamping segments regularly. Keep air vents clear.
Troubleshooting
If the display is blank, check the battery. If the core bit is jammed, use an open-end wrench to release it.
