3. OPERATION
PRELIMINARY CONTROLS
Inspect the working area as explained in the safety instructions. For dry use connect the vacuum extractor and ensure that the vacuum
hose is clear and it will follow the machine easily. Plug in the machine and make sure that the power cord is free to follow the working
direction of the Lavina®13E.
MOUNTING TOOLS
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 Quick Change tools with the security plate (Fig.3.2 in red), lock with the tool holder key
(Fig.3.3) and make sure that the butterfly is securely locked at 90 degrees. Diamond tools with Velcro are attached on
three foam plates (13,2 inch). The foam plates are mounted on the key lock (butterfly). Always use the tool holder key
(Fig.4.2).
LEVELING AFTER MOUNTING THE TOOL
On top of the base plate is mounted a water level (Fig. 3.4). Designed to establish the good working position of the tools and
adjusted by the operator in the different ranges:
Turn left and right on 45° by releasing the screw handle (Fig. 3.4)

Tilt crosswise to the left and to the right to 4° - release the screw handle (Fig. 3.5)
Using the handle (Fig 3.6) and guided by the index line and the levelling put the operating part in the desired crosswise position
and screw the handle (Fig 3.5)
Using the vertical screw (Fig 3.7) and guided by the leveling adjust the operating part to flat position or find the required
lengthwise tilt (forward or backward).
ADJUSTING HANDLE
The Handle on the frame is adjustable in height and allows the operator to work in a correct and safe posture (Fig. 3.8, Fig.
3.9 and Fig.3.10). Choose the upright position to move easy the machine.
TOOL PROTECTING GUARD
The protecting guard has free movement and is self-adjusting according to the height of the tool abrasion and is turning in the range
of 45°clockwise or anti clockwise following the wall (Fig 3.11). The height of the brush is adjusted only when using the Foam plate
(Fig.4.3). The adjustment is made by unscrewing the bolts on the side of the guard (Fig 3.12) and pulling out the brush to the desired
position.
The plastic rolls on the protecting guard serve to protect the wall from damages (Figure 3.11). By moving the roll in the hole (Figure
3.13) can be adjusted the distance of the working tool to the wall.

9. RUN button starts motor
10. LED lights switch
STARTING THE MACHINE
First, follow the directions in chapter Safety Devices and Safety Instructions. Next, pull the emergency stop (Fig. 3.14 4) and turn the
ready switch (Fig. 3.14 7) in position ON to put the machine in standby mode to start. Check the potentiometer (Fig. 3.14 6) and
ensure that it is set at the working speed. Switch on the vacuum unit. Finally, hold the machine firmly and push the run button (Fig.
3.14 9).
OPERATING THE MACHINE
Work at a constant speed allowing the tools time to work at a speed appropriate for the tools’ grit size. Avoid vibrations. Do not stop
the Lavina ®13E machine in one spot while the tools are still working because they will leave marks on the floor surface. Check the
floor surface periodically to ensure that dust is not accumulating on the surface, also check regularly if your vacuum works properly.
In case you use Lavina ®13E as one disc machine for floor maintenance guide the machine in straight lines across the floor, and with
each new line overlap a little bit of the previously completed surface.
STOPPING THE MACHINE
The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine before arresting the
Motor, as the tools could damage the surface.
To stop the machine:
1.Push the STOP button (8) .
2.Turn the OFF/ON (7) switch in position OFF, this will cut the voltage to the invertor and the green light will turn off.
While working do not turn off directly from the switch READY OFF / ON or from the Emergency Stop, but follow the above
mentioned steps 1 and 2.
Use the Emergency button (4) only in emergency.
Remember not to hold the machine in one spot before turning off the motor.
