The chain brake can be activated in two modes: the first using the left wrist by pushing forwards, or when it comes into contact with the brake system as a result of kickback; or by inertia, in the case of particularly violent kickback.
When the machine is used with the bar in horizontal position, for example during tree felling, the chain brake offers less protection, because it can be activated by inertia only, since the user’s hand is outside the range of action of the front hand guard (fig.3).
N.B.: When the chain brake is activated, a safety switch cuts off all current to the motor.
CHAIN CATCHER
This machine is equipped with a chain catcher (fig.4) located under the pinion. This mechanism is designed to arrest the backward chain movement in the case of chain breaking or derailing. These situations can be avoided by ensuring correct chain tension (Refer to chapter “D. Assembly/disassembly”).
REAR HAND GUARD
This acts to protect(fig.5) the hand in the case of chain breaking or derailing.

BAR AND CHAIN ASSEMBLY
Assembly methods change according to the type of your machine- so please take care to refer to the illustrations and machine type marked on the label (A- Legend – 9 [ES15 / ES16 / ES18] ), Take great care when assembling to ensure this is performed correctly.

4.Oil the chain, then position it over the pinion, making it slide into the bar guide groove, beginning with the upper part. Attention! Control that the sharp side of the cutting teeth face in a frontward direction on the upper part of the bar; Set the chain tensioner pin in the chain tensioner pin housing. Mount the chain cover making sure that the drive teeth of the chain are engaged in the pinion and in the guide groove.

7 Spread the chain until the tension is correct; that is, when the chain is pulled upwards, the drive tooth rise to the same level as the bar. (the chain must never droop on the underside of the bar)
8a. Tighten the bar retaining nuts using an appropriate tool.
8b. Tighten the bar retaining knob strongly.
Tensioning the chain too tightly will overload the motor and cause damage, insufficient tension can provoke chain derailing, whereas a chain tightened correctly provides the best cutting characteristics and prolonged work life. Check the tension regularly because the chain length tends to stretch with use (especially when the chain is new; after the first assembly, the chain tension must be controlled after 5 minutes machine operation); in any
