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.

FOR ES 15 / ES 16

FOR ES 18

Control that the chain brake is not activated. If so, deactivate it.

2a.

Unscrew the

bar retaining nuts

and remove

the

chain cover

2b.

Unscrew the

bar retaining knob

and remove the

chain cover.

3a.

Mount the

bar

on the

bar retaining screws

pushing it as far backward towards the

pinion

as possible.

3b.

Mount the

bar

on the

bar retaining screw

pushing

it as far backward towards the

pinion

as possible.

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.

5a.

Close the

bar retaining nuts,

screwing by

hand.

5b.

Screw the

bar retaining knob

loosely tightened.

6a.

To spread the

chain

screw the

chain

tensioner screws

in a clockwise direction, to

loosen tension, screw in an anti-clockwise
direction (when performing this operation
maintain the

bar nose

raised upwards

)

6b.

To spread the

chain

screw the

chain tensioner

knob

in a clockwise direction, to

loosen tension, screw

in an anti-clockwise direction (when performing this
operation maintain the

bar nose

raised upwards

)

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.

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
