4. OPERATION
PRELIMINARY CONTROLS
Inspect the working area as explained in the safety instructions. For wet use, fill the water tank with the electrical cable disconnected.
Connect the vacuum extractor and ensure that the vacuum hose is clear and will easily follow the machine. Plug in the machine and
make sure that the power cord is free to follow the working direction of the Lavina® X machine.
WATER FLOW CONTROL UNIT
The operator can direct water to be sprayed in the front
(Fig.4.1) by positioning the lever in the horizontal position;
the water will spray under the cover of the machine when
the lever is in the vertical position (Fig.4.2). The flow
regulating valve located on the tank (Fig.4.3) controls the
water flow to the working area – in front of the machine or
under the main head cover of the machine.
ADJUSTING AND MOUNTING TOOLS
The Holder A41 in LAVINA® X can work with either 3 or 6 buffers, which will
alter its range of motion. You can make the change after dismounting the
holder as per the instructions in TROUBLESHOOTING.
In the Lavina 20‐X, the holder is initially mounted with 3 buffers.
Mount the tools only after ensuring that there is enough diamond bond
material left. Be sure that the plates are always clean before mounting.
WARNING: Always secure the "Quickchange" pads with the security plate
(Fig.4.4), and lock with the tool holder key (Fig.4.5). Diamond tools with Velcro are attached on three 9inch foam plates. The foam
plates are mounted on the key lock (butterfly). Always use the tool holder key (Fig.5.3).
