1. During these operations, the worn gloves must be heatproof to protect hands from contact with
hot food or hot parts of the appliance and/or when removing hot items from
it.
Failure to use the
personal protection equipment by operators, specialized personnel or users can involve exposure
to chemical risk and possible damage
to health (depending on the model).
2. During these operations, the worn gloves must be cut-resistant. Failure to use the personal pro-
tection equipment by operators, specialized personnel or users can involve exposure to damage
to health (depending on the model).
GENERAL INFORMATION
•The machines are provided with electric and/or mechanical safety devices for protecting workers
and the machine itself. Therefore, the user must not remove or tamper with such devices. The Manufacturer
declines any liability for damage due to tampering or their non-use.
•Never operate the machine, removing, modifying or tampering with the guards, protection or safety de-
vices.
•Do not make any modifications to the parts supplied with the appliance.
•Several illustrations in the manual show the machine, or parts of it, without guards or with guards
removed. This is purely for explanatory purposes. Do not use the machine without the guards or with the
protection devices deactivated.
•Do not remove, tamper with or make illegible the safety, danger and instruction signs and labels on
the machine.

10
LIBERO LINE WOK INDUCTION
•Air recirculation must take into account the air necessary for combustion, 2 m³/h/kW of
gas power, and also the "well-being" of persons working in the kitchen.
•Inadequate ventilation causes asphyxia. Do not obstruct the ventilation system in the place where this
appliance is installed. Do not obstruct the vents or ducts of this or other appliances.
•Place emergency telephone numbers in a visible position.
•The measured sound level emitted “A“ does not exceed 70 dB (“A“).
•Turn the appliance off in case of fault or poor operation.
•Do not use products (even if diluted) containing chlorine (sodium hypochlorite, hydrochloric or
muriatic acid, etc.) to clean the appliance or the floor under it.
•Do not use metal tools to clean steel parts (wire brushes or ScotchBrite type scouring pads).
•Do not allow oil or grease to come into contact with plastic parts. Do not allow dirt, fat, food or other residu-
als to form deposits on the appliance.
•Do not spray water or use steam to clean the equipment.
•Do not store or use gasoline or other flammable vapors, liquids or items in the vicinity of this or any
other appliance.
•Do not spray aerosols in the vicinity of this appliance while it is in operation.
•Never check for leaks with an open flame.
RESIDUAL RISKS
•The machine has several risks that were not completely eliminated from a design standpoint or with
the installation of adequate protection devices. Nevertheless, through this manual the Manufacturer has taken
steps to inform operators of such risks, carefully indicating the
personal protection equipment to be used by them. Sufficient spaces are provided for during the machine
installation stages in order to limit these risks.
To preserve these conditions, the areas around the machine must always be:
–kept free of obstacles (e.g. ladders, tools, containers, boxes, etc.);
–clean and dry;
–well lit.
For the Customer's complete information, the residual risks remaining on the machine are indicated below:
such actions are deemed improper and therefore strictly forbidden.
Residual risk
Description of hazardous situation
Slipping or falling
The operator can slip due to water or dirt on the floor
Burns/abrasions (e.g. heating elements)
The operator deliberately or unintentionally touches some compo-
nents inside the machine without using protective gloves
Electrocution
Contact with live parts during maintenance operations carried out
with the electrical panel powered
Sudden closing of the lid/ door/oven door (if pre-
sent, depending on
the appliance type)
The operator for normal machine use could suddenly and deliber-
atelyclose the lid/door/oven door (if present, depending on the ap-
pliance type)
Tipping of loads
When handling the machine or the packing containing it, using un-
suitable lifting systems or accessories or with the load unbalanced
Mechanical safety characteristics, hazards
