Planing; Repair And Maintenance - Proxxon DH 40 Mode D'emploi

Planing

Caution:
Never use your hand to reach into the infeed slot while
the planer is in operation! Risk of injury!
Caution:
Wear protective goggles.
Caution:
The service flap must always be closed during operation.
The planer is now ready for operation. The height of the
planing table 2 and thus the pass-through height and the
depth of cut (i.e. the "planing depth") can now be set on
the hand wheel 1 (Fig. 3). The position of the planing
table must, of course, first be set roughly to the thickness
of the workpiece. This can expediently be estimated by
means of the linear scale 3 at the side of the inlet
opening. The value printed here gives the distance
between the tips of the planing cutters and the surface of
the planing table. If this value is the same as the thick-
ness of the workpiece, the depth of cut (i.e. the "shaving
thickness" so to speak) is exactly "zero".
Note:
It is recommended that the opening be set rather
"generously" and the workpiece run through a few times.
increasing the depth of cut a little each time by turning the
hand wheel to the left in order to obtain a feel for the
correct height. When the planing cutter just comes into
contact with the top edge of the workpiece while it is
passing through, then the depth of cut is zero.
The scale ring 4 on the hand wheel can now be set to
zero. There is a mark 5 on the housing to assist with this.
The required depth of cut can now be set using the hand
wheel. One turn corresponds to one millimetre stroke of
the planing table, i.e. if it is required to make a reduction
of 0.5 millimetres, the hand wheel must be turned to the
left by half a turn. The exact value can be read off on the
scale ring.
Note:
Although your planer is a solid and robustly made
machine, in spite of this it is primarily intended for fine and
precise working. Do not overload the planer by machining
harder types of wood with large depths of cut and a cor-
responding width of workpiece over a long period of time.
Please note:
When you have run the workpiece through and planed it
a few times and are approaching the required thickness,
it is recommended that the last passes be made with a
rather smaller depth of cut in the interests of a better
surface quality.
If the workpiece is drawn in but comes to a stop after a
few centimetres, then the depth of cut has been set too
large. In this case, turn the hand wheel to the right to
lower the planing table and thus reduce the depth of cut.
The workpiece will then be drawn in normally once more.
Then continue to plane until the required thickness is
achieved.
Note:
Make sure that no work pieces are inserted, which are
higher than 40 mm.
In this case, the workpiece will no longer be pushed
through by the draw-in roller in the planer and can
become stuck in the kickback device, which normally
prevents the workpiece from sliding back.
Note:
Depending on the amount of accumulated dust, we
recommend cleaning the chip discharge channel (pos.
11, Fig. 1) with a vacuum cleaner. Caution! Always switch
off the planer!

Repair and maintenance

Changing or reversing the planing cutters
The cutter shaft of your planer is equipped with 2 rever-
sible cutters for the highest surface quality. Each of the
fitted planer cutters 6 (Fig. 4) has two blades (reversible
cutters). When the first has become worn or damaged,
you can simply remove the cutter, reverse it and use the
other side. When this is no longer sharp enough, then
new cutters must be fitted. Remember always to reverse
or replace the cutters in pairs.
You can obtain replacement cutters from your dealer.
Use only the spare knives intended for the machine!
Note:
Used planing cutters must not be reground. Please al-
ways replace or reverse them. Replace damaged planing
cutters immediately.
Caution:
Please only handle the cutters with extreme care, as
these are very sharp. Risk of injury!
Caution:
When carrying out any repair and service work, it is es-
sential that the mains plug be removed in order to prevent
accidental starting of the planer.
Risk of injury!
1. Undo the four Allen screws 1 and remove the side
cover. Then remove the locking screw 2 (Fig. 5).
