6 Cleaning and Maintenance

6.1 General Safety Information

WARNING

Read the safety instructions 

before starting any cleaning or 

maintenance work.

DANGER

Lockout the main power source 
with the disconnect on the door 
of the electrical enclosure per 
OSHA Standard 1910.147.  This 
precaution must be taken to avoid 
the possibility of a serious shock 
hazard, or an accidental cycling of 
the Former which could cause a 
very serious injury.

• 

Switch off the compressed-air.

• 

Open all covers and doors.

• 

Allow heated elements to cool 
sufficiently.

CAUTION

NEVER use compressed air to clean 

the machine. Always use a vacuum 

cleaner or a brush. Dust could 

be stuck in bearings or in gears, 

increasing the risk of premature 

wear. 

INFORMATION

Any Cleaning or maintenance work 

should only be carried out by 

trained personnel.  

• 

Do not remove parts for 
cleaning unless specified in 
these procedures. Unnecessary 
removal of parts could result in 
misalignment and subsequent 
damage to the machine.

• 

Remove all tools and cleaning 
supplies before running the 
machine again.

• 

To prevent malfunctions and 
damage to the Former, after 
performing maintenance tasks, 
check the equipment for correct 
reassembly.
