Chainsaw Repair

Semi chisel isnt safety chain , unless you buy  semi in safety type.  I buy full chisel  and if I bought semi chisel it would be the non-safety bumpers type. 

Like RM RMC semi chisel is non safety , RMC3 is safety semi chisel.  RS RSK RSC is full chisel  non safety and RSC3 is safety chain in full chisel. Those were all stihl chain examples.

Look  at the 4 sticky threads explaining chains and types.  http://chainsawrepair.createaforum.com/chain/
