4.8. CHECKING AND TIGHTENING THE DRIVE CHAIN                                        (Figure 10) 

 
During  the  operation  and  under  the  load,  the  drive  chain  stretches,  therefore  the  operator 
must check and readjust the chain periodically to prevent excessive wear of the whole chain 
drive. The chain must not be set to tight and chain slack should be set 1 to 3 mm. Shorther 
chain should allow ±1 mm slack and longer chain ±3 mm. Check the tightness of the chain by 
hand, pushing the chain between the chain wheels. 
 
Lubricate the chain using special chain lubrication spray.
