GENERAL SAFETY GUIDELINES

 

Before beginning to operate on 

HPE

 units every user has to be perfectly knowledgeable about the functions of the equipment 

and its controls and has to have read and understood the information listed in this manual. 

It’s strictly forbidden to remove and/or tamper with any safety device.

 

Children or unassisted disabled persons are not allowed to use the appliance. 

Do not touch the appliance when barefoot or parts of the body are wet or damp. 

Do not clean the unit when the power supply is ‘ON’. 

Do not pull, remove or twist the electrical cables coming out from the unit, even if it is disconnected from the main 

power supply. 

Do not step with your feet on the appliance, sit down and/or place any type of object. 

Do not spray or pour water directly on the unit. 

Do not dispose of, abandon or leave within reach of children packaging materials (cardboard, staples, plastic bags, 

etc.) as they may represent an environmental and life hazard. 

Any routine and/or not-routine maintenance operation shall be carried out when the equipment has been shut down, 

disconnected from electric and pneumatic power sources and after its pneumatic system has been discharged. 
Do not put neither your hands nor insert screwdrivers, spanners or other tools into moving parts of the equipment. 
The equipment supervisor and the maintenance man have to receive suitable training for the performance of their 

tasks in safety. 

Operators have to know how to use personal protective devices and have to know the accident-prevention guidelines 

contained in national and international laws and norms. 

4.1

 

WORKERS’ HEALTH AND SAFETY 

The European Community has adopted a number of directives on workplace’s health and safety, including 

89/391/CEE

89/686/CEE, 89/655/CEE, 2009/104/CE, 86/188/CEE 

and

 77/576/CEE

 directives. Every employer shall implement such norms and 

ensure that workers to respect them. It points out that: 

Do not tamper with or replace parts of the equipment without the specific consent of the manufacturer. The 

manufacturer shall have no responsibility whatsoever in case of unauthorised operations.

 

Using components, expendable materials or spare parts that do not correspond to those recommended by the 

manufacturer and/or listed in this manual may be dangerous for the operators and/or damage the equipment 

The operator’s workplace has to be kept clean, tidy and free from objects that may prevent free movements. 

Appropriate lighting of the work place shall be provided so as to allow the operator to carry out the required 

operations safely. Poor or too strong lighting can cause risks. 

Ensure that work places are always adequately ventilated and that aspirators are working, in good condition and in 

compliance with the requirements of the laws in force. 

4.2

 

PERSONAL SAFETY EQUIPMENTS 

When operating and maintaining the “

HPE

” units, use the following personal protective equipment. 

Protective clothing: Maintenance man and operators have to wear protective clothing that complies with the basic 

safety requirements currently in force. In case of slippery floors, users have to wear safety shoes with non-slip soles. 

Gloves: During maintenance or cleaning operation protection gloves have to be used 

Mask and goggles: Respiratory protection (mask) and eye protection (goggles) should be used during 

cleaning and maintenance operations. 

4.3

 

SAFETY SYMBOLS 

The unit features the following safety signs, which has to be complied with: 

General hazards 

Electric 

shock

 hazard

 

Presence of moving organs 

Presence of surfaces that may cause injures 

Presence of hot surfaces that can cause burns
