Safe Use  

 

The Lavina® E is designed to reduce risks correlated with its use. 

However, it is not possible to fully eliminate the risks of an accident 
with the machine. An unskilled or uninstructed operator may cause 
correlated residual risks. Such risks are:

 

• 

Position Risks: due to operator’s incorrect working position

 

• 

Entanglement Risks: due to wearing inappropriate 

working clothes

 

• 

Training Risks: due to lack of operational training.

 

• 

 

NOTE

: In order to reduce any consequences of the 

above‐ mentioned risks, we advise that machine operators 
follow the instructions in the manual at all times.

 

Residual Risks

 

 

 

During the normal operating and maintenance cycles, the operator 

is exposed to some residual risks, which cannot be eliminated due 

 

to the nature of the operations. 

 

Before You Begin 

 

 

Working area must be clear from any debris or objects.

 

 

A first‐time operator must always read the manual and pay 
attention to all safety instructions.

 

 

All electric connections and cables must be inspected for 
potential damages.

 

 

Ground wire system of the power supply must be also 
inspected.

 

 

Perform general daily inspections of the machine and inspect 
the machine before each use.

 

 

Always inspect the safety devices: Mount the Security plate 
for the QuickChange pads.

 

 

The emergency break must be clear and working

 

 

The tool protector must be working

 

 

The machine must be clean  Never operate the machine in 
the rain!

 

 

Confirm that there are no missing parts especially after

 

transportation, repair or maintenance. 

 

• 

Before filling the water tank with water make sure the 
machine is not working and the main switch is turned off.

 

• 

Before turning on the machine make sure that the base is 
placed on the floor, the machine MUST NOT be in an upright 
position when turned on!

 

Operating Machine

 

 

 

When operating the Lavina® E, make certain that there is no one 

but you around the machine. 

 

Never leave the machine unattended while working. The 

electrical cable must move freely and must be damage‐ free. 

 

The water hose must move freely and must be damage‐free. 

Check to make sure the floor you are preparing to work on is 

 

even. If the floor is uneven, it may damage the machine.
