shortest possible cutting length in order to reduce
the risk of the bit decentring. The bit, chuck collet
and adaptor should be completely clean before
attachment.
Do not leave the machine without a
cutting tool, as this exerts excessive
pressure on the chuck collet and can
damage the shaft housing.
Never start the machine while the bit
lock button is pressed.
8. BLOCKING OF THE BASE
The base may be locked in any position by turning
locking lever E (Fig. 3) in the counter-clockwise. The
action of the springs incorporated in the columns
means that when this lever is loosened the base
automatically returns to its highest position.
After use, always turn the switch to
the off position and release the base
using the locking lever J (Fig. 3) before
placing the router on a flat surface.
9. ADJUSTING THE DEPTH
ADJUSTING THE DEPTH. The depth is adjusted
by using the incorporated rack and pinion depth-
adjustment mechanism.
With the cutter bit face flush against the wood
surface, the penetration depth may be adjusted up
to 60 mm.
To unlock the depth rod K (Fig. 4) press down firmly
on adjustment knob L (Fig. 4) and turn it to raise or
lower the depth rod, if a greater or lesser cutting
depth is required. The gauged adjustment indicator
M (Fig. 4) can be moved separately from the knob, so
that it may be set to zero from any position using the
reference mark. When turning the knob after adjus-
ting the indicator, both elements will turn together,
there by indicating the degree to which the rod has
been moved. A full turn of the knob moves the rod
by 34 mm, with a maximum distance of 55 mm.
To hold the depth rod in the required position, release
the pressure from the adjustment knob. Next, to
ensure that the rod is firmly held in place, it should
be locked using fastening knob N (Fig. 4).
PRECISION ADJUSTMENT. If you wish to make
precision adjustments to the previously set depth,
simply turn adjustment knob O (Fig. 4). A full turn
of the knob moves the rod by 1 mm, with a maxi-
mum distance of 5 mm. Each division in the gauged
fine-adjustment indicator P (Fig. 4) represents an
advance of 0.1 mm.
MAKING DEEP CUTS. To safely make cuts that are
too deep to be made with a single pass, we recom-
mend making several successive cuts using the six
3-mm steps in the revolving depth turret Q (Fig. 4).
Lower the machine until the cutting bit is level with
the surface on which the router is resting. Use locking
knob J (Fig. 3) to hold the machine in this position.
Loosen fastening knob N (Fig. 4), then press down
and turn adjustment knob L (Fig. 4) until the depth
rod presses against the lower step of the revolving
depth turret, using fine adjustment if required. In
this position, turn depth indicator M (Fig. 4) until
position zero matches the reference mark. This
will be the starting position indicating the point at
which the bit comes into contact with the material.
Hold the rod in place with knob N (Fig. 4), release
the locking knob J (Fig. 3) and leave the machine in
the off position.
Loosen fastening knob N (Fig. 4), then press down
and turn adjustment knob L (Fig. 4), moving the
adjustment rod K (Fig. 4) upwards to the required cut
depth. Then use knob N once again to turn turret Q
(Fig. 4) until the highest step is below rod K (Fig. 4).
Make the first cut on the material. Turn the turret
Q to the next step and then make another cut, and
so on until the required depth is obtained when the
bottom step is reached.
10. LOCKING THE ROUTING DEPTH
To carry out several repetitive jobs in which the
router depth is always the same, it may be useful to
prevent the head from being released by accidentally
moving the locking knob J (Fig. 3). This may be done
by inserting two M8 nuts R (Fig. 3) in the threaded
shaft, one above and one below the head body. This
locks the head at any point along its depth setting.
When working with the router depth
locked, the tool will be permanently
outside the base surface. Therefore
the following actions must be taken:
- Wait until the machine has come to a complete stop
before setting it down on its base, on a flat surface,
with the cutting tool free.
- Remove nuts R (Fig. 3) to return to the normal
lock conditions using lever J (Fig. 3), once the job
is complete.
