Locking cut-out

Pressing the locking cut-out enables the ON/OFF function. This cut-out

 

ensures secure locking of the 

HCH50 Chain Saw

Front

 handle

The 

front

 handle is used to hold and carry the 

HCH50 Chain Saw.

Operating handle with manual starter

The operating handle with manual starter is secured by the locking cut-out 

against  unintentional  activation.  This  must  be  operated  before  the

Couplings

The HCH50 Chain Saw is connected to the power source (power 
unit) 

and water source 

via the couplings.
