CHAPTER 8:   MAINTENANCE

8.1

CLEANING

The equipment exterior can normally be kept clean just by wiping it with a dry cloth. If necessary, 
wet the cloth just a little water or use a non-degreasing detergent.
The operator must ensure that the equipment is kept clean and free from any foreign bodies 
such as dirt, water, non-conducting liquids etc.
The equipment must be cleaned at the end of every work session to remove all residues. 
Cleaning must be done with the equipment at standstill and positioned in a stable manner.

8.2

 ROUTINE MAINTENANCE

Once the equipment has been cleaned (see section 8.1) the operator must check for worn,
damaged or loose parts. If any such anomalies are discovered contact your Authorised 
Servicing Centre.

Never use inflammable, corrosive, alkaline or toxic liquids when cleaning the 
equipment.

Eye goggles and a face mask must be worn when using compressed air for 
cleaning purposes. Do not allow any persons near the equipment as they could 
be hit by flying dust.

Before cleaning the equipment exterior always turn the main switch to OFF. It is 
strictly forbidden to clean the equipment while it is connected to the mains 
power supply.

Should any of the above anomalies be discovered it is strictly forbidden to 
restart the equipment before such faults have been set right.

Never use a naked flame to see what you are doing during checks or maintenance 
operations.

More precisely, should the operator note any defects or problems of any kind whatsoever he/she 
must place a warning sign on the equipment indicating that maintenance work is in progress and 
that using the equipment is forbidden (EC-compliant signs can be purchased from the relevant 
suppliers).

Routine maintenance, cleaning and proper equipment use are essential factors in guaranteeing 
long-lasting equipment performance and safety.
