In the STIHL KombiSystem a number of 
different KombiEngines and KombiTools 
can be combined to produce a power 
tool. In this instruction manual the 
functional unit formed by the 
KombiEngine and KombiTools is 
referred to as the power tool.
Therefore, the separate instruction 
manuals for the KombiEngine and 
KombiTool should be used together for 
the power tool.
Always read and and make sure you 
understand both instruction manuals 
before using your power tool for the first 
time and keep them in a safe place for 
future reference.
