Chain wheel change
Danger
Pull the power plug during all
service work.
•
During a chain wheel change, the countersunk
screw in the gear shaft must be unscrewed with
the Allen key fastened on the machine by
knocking lightly against the key.
•
For installation, proceed in reverse order. Push
the new chain wheel onto the gear shaft such
that the chain wheel groove gears into the
straight pin, which is pushed crossways through
the gear shaft.

Operation
5.1
Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular attention to the chapter "Safety
instructions".
5.2
Switching on and off
Danger
Pay attention that the mortising
chain can be moved freely.
Lead the connecting cable away to
the rear.
Hold onto the machine with both
hands.
Only switch on the machine if the
mortising chain has no contact with
the workpiece.
•
Switching on:
First unlock the switch-on lock to
the front by pressing the locking lever 4 (Fig. 2).
Then actuate the control lever 3. As this is a
switch without locking device, the machine will
only run for as long as this switch is pressed.
•
Switching off:
Release control lever 3. The
switch-on lock automatically takes effect again
and secures the machine against accidental
switch-on.
Switch-on procedures create a
temporary reduction in voltage. In
case of unfavourable grid
conditions, this may lead to the
impairment of other devices.
In case of grid impedances smaller
than 0.27 Ohm, no interferences
are to be expected.
5.3
Cross fence setting
The distance between mortise and collar side is
steplessly variable from 8 to 150 mm (5/16 to 5 7/8
in.) with the crossfeed stop 6 (Fig. 2).
•
Release the clamping lever 8 and set the
distance on scale 7. Note the reading edge
depending on the hole width 30, 35 or 40 mm (1
3/16, 1 3/8 or 1 9/16 in.)!
•
Securely retighten the clamping lever 8
afterwards. The clamping lever is adjustable and
can be brought into any desired clamping
position by lifting it.
5.4
Mortising depth adjustment
The mortise depth is continuously variable.
•
Release clamping lever 10 (Fig. 2) and set the
depth stop 9 to depth using a yard stick.
•
Tighten clamping lever 10 (adjustable as 8) - do
not place in mortising direction! The mortising
depth depends on the mortising chain set used.
5.5
Operating method
To start mortising, hold the machine by its two
handles 1 and 2 (Fig. 2) and guide it - the crossfeed
stop 6 must rest against the wood. First mortise the
start and end of the mortise and then the rest. Mortise
with even pressure and infeed. The mortising chain
should be cleaned and lubricated in a low viscosity oil
bath after two hours of operation.
5.6
Mortising recesses
For this, two wooden ledges can be screwed on at
the drill holes Ø 4.5 mm (11/64 in.) on the crossfeed
stop 6 (Fig. 2) (see Fig. 4).
