4. Preparing the equipment for use
4.1 Assembly of the guide bar and chain
• Undo the retaining nuts on the rail cover (12).
• Take off the rail cover.
• When setting up the tool for the first time, remove
the cardboard disc inserted at the factory as
transport protection underneath the rail cover
before installing the guide bar.
• On used saws, clean the rail contact surface and
the oil outlet.
• Use the chain tensioning bolt (13) to move the
chain tensioning cam to the left-hand end stop.
Note:
Each time the guide bar is removed and
installed, adjust the chain tension cam (b) up to
the l.h. end stop.
On the models 656 and 656H the corresponding sprocket (enclosed with the accessories) for the
cutting gear should be installed. Notes on this can be found in the instructions included with the
accessories.
Always install matching components (sprocket, guide rail, saw chain) (see Chapter 9,
"Permissible cutting gear and further accessories", page 40).
Note for new saw chains:
Before installing a new saw chain we recommend soaking it in a container (bowl) with chain oil with
anti-fling properties for a certain amount of time (preferably overnight).
• Position the guide bar; in the process, the
chain tensioning cam must fully engage in
the designated hole in the guide bar.
• Fit the chain over the sprocket and into
the guide groove of the guide bar.
• The cutting elements of the saw teeth
must be on the upper side of the rail
facing towards the tip of the rail.
• Make sure that the drive links engage
correctly in the cutouts of the sprocket
and in the guide sprocket at the rail tip.
• Fit the rail cover, but initially only tighten
the retaining nuts finger tight.
• After correctly adjusting the chain tension (refer to the next section), tighten the retaining nuts as
described below.
