After you have removed the ancillary flange, you can insert the grinding
disk in the body from below. See that the ancillary flange and the disk abut
against each other precisely. (Fig.6).
Do not tighten the screws too much to avoid any damage to the disk. The
grinding disk on the hub torque is 7Nm. Where practicable, use a torque
spanner. Now, the grinding disk additional guard should be fitted on (Fig.7).
Check the correct bottoming of the disk: in should not move across and
lengthwise. Now, with the grinding disk properly installed, a trial may be
performed. Stand by the machine from the side and watch out for anybody
dwelling in the working area.
If the grinding disk is vibrating or shows otherwise incorrect run, promptly
switch off and unplug the machine before you attempt clearing the fault.
The machine has a zero voltage circuit breaker, which is disabled on outage
and will prevent any restarting of the machine after the power supply is
restored.
Using the sharpening stone and a clamping plate, it is possible to sharpen
the disk to obtain the required profile. In this case, be careful at work.

Before the start of grinding, the chain should be conducted between both the
attachment guides. Now, the tooth be sharpened first should be taken against the
stop. Watch out for the sharpening angle to correspond to the guides position. The
type of the chain to be sharpened should be determined using the sharpening
block provide or the table p.9. There, you can find out the cutting thickness,
angles and dimensions.
Loosen the mounting screw (10b) and place the cutting chain in the guide
rail between the guide plate (11).
Fold the chain stop (12) down and pull the chain toward the back until the
cutting link to be ground rests against the stop.
Set top plate angle by means of the set screw (P.2,P.4) and
it may be also
read on the scale (F). The vice angle should be set up by set screw .
With the clamping screw adjusted and the vice angle set up (Notice: RH and LH
teeth to be differentiated) and preset the top plate angle, set the distance with the
help of the mounting screw (10a), lead the grinding disk down to the tooth by soft
pushing the supporting strut. The grind depth may be set by set screw (K) .
Tighten the mounting screw (10b), now, the machine may be switched on and the
saw-chain grinding may be started by a careful thrust on the grinding disk. Adjust
the pressure as necessary. Mark the start of grinding e.g. with a piece of chalk and
grind all the teeth in one direction, then turn the clamping screw (mind the angle)
and grind the teeth in opposite direction.
With warn chains, the lateral guide position shall be set for the grinding disk not
to touch the guide.
Avoid any strong thrust as the teeth might collide and the chain would wear and
tear too fast.
Notice: Never grind any driven parts.
