Externally:

 by lubricating and wiping the chain drive with oily cloth. The frequency of 

lubrication depends on entirely upon the usage of the machine and environment in which 
the machine is placed (dust, moisture etc.). 
Machines working under extremely dirty conditions should be lubricated every 400 operating 
hours but at minimum, every 2 months. Longer lubrication intervals may occur only when 
machine is working under very clean and dry conditions but should be not be longer than 6 
months.

TOWER RACEWAYS MAINTENANCE 

 
The film distributor (carriage) is sliding on the plastic guides attached behind its back plate. 
The section of the tower on which the plastic guides move (raceways) should be cleaned 
and re-greased approximately every 600 hours of machine operation. 
NOTICE: If the machine works in a dusty and corrosive environment, the raceways should 
be re-greased more often (at least every 100 hours). 
 

CHAIN MAINTENANCE 

 
To clean the chain, wipe it with an oily cloth every month. When machine is working in a 
dusty and damp environment, it may be necessary to repeat the cleaning operation more 
often. As the chain lubricants please use the most common chain lubricants on the market. 
With time, the chain will tend to stretch. A loose chain should be tightened at the chain 
tensioner, or by moving the reducer on its mounting plate. 
NOTICE: Chain tension first adjustment must be done after the first two weeks of machine 
usage. 
 

PNEUMATIC SYSTEM MAINTENANCE (when applicable) 

 
The air supply system must be checked weekly and must be free from the moisture. In cold 
environments, it may be necessary to drain the air supply system daily. 
 

CAM FOLLOWER MAINTENANCE (when applicable) 

 
The cam followers have deep grease pockets and do not need frequent relubrication. The 
portion of the tower on which the cam followers run, should be cleaned and regreased every 
300 hours of operation. If the machine operates in a dusty or corrosive environment the 
tower should be relubricated more often.
