10.4 Suction system (fig. 1 + 8)
• Connect the planing machine at the suction ports
(25) to a chip extraction unit (not in scope of deliv-
ery) using the suction adapter (5), if necessary.
• A suction system must be used for extracting the
wood chippings and dust. The flow speed at the
suction ports must be at least 20 m/s.
10.5 Changing the planing blade (fig. 16-19)
m ATTENTION! Disconnect the mains plug before
carrying out any maintenance, cleaning or adjust-
ment work.
• The planing shaft cover (34) on the planer (16) is
found on the back of the machine where there are 2
magnetic holders (32) and an Allen key holder (33).
• Crank the planer all the way down (see 10.1)
• Remove the suction hose (27) (see 9.4)
• Remove the planing shaft cover (34).
• Remove the 4 hexagon socket screws for the plan-
ing shaft cover (35) using the Allen key (22).
m ATTENTION! Planing blades are sharp! Always
wear suitable work gloves when changing the planing
blades.
• Remove the 6 planing blade (36) screw fittings using
the Allen key (22).
• Remove the terminal strip (37) and the planing
blade (38) carefully from the planing shaft (40) with
the 2 magnets (21). Make sure that the 2 springs for
the planing blade protection (39) are not lost.
• The planing blade (38) can now be turned over or a
new planing blade (38) can be inserted. If the plan-
ing blade must be turned over, mark the already
used edge with a waterproof marker.
• Fit the planing blade (38) to the planing shaft in re-
verse order. Make sure that the planing blade hold-
ing pins (41) prevent the planing blades (38) from
sliding. Furthermore, ensure that the 2 planing
blade protection springs (39) are in the correct posi-
tion. Another adjustment is not required.
• Tighten the planing blade screws firmly. Check this
several times.
• Repeat the above described steps for the 2 planing
blades (38) that can be reached by carefully turning
the planing shaft (40).
• Fit the planing shaft cover (34) and the suction hose
(27) in reverse order after changing the planing
blade.
10.6 Changing the carbon brushes (fig. 20)
m ATTENTION! Disconnect the mains plug before
carrying out any maintenance, cleaning or adjust-
ment work.
• Check the condition of the brushes after approx. 50
operating hours. These must be replaced when the
brush length is below 3 mm. (2 pieces required) Al-
ways replace in pairs.
10.7 Workpiece return rollers (fig. 1)
The workpiece return rollers (2) serve to return a fin-
ished planed workpiece or to place it on the machine
without scratching the machine housing (1).
11. Working instructions
• Only work with sharp planing blades!
• Insert the workpiece with the thicker end first, hol-
low side at the bottom.
• The maximum chip removal of this planer is 2.8 mm.
However, this dimension may only be utilised with
the following factors:
- When the workpiece width is 152 mm;
- When using very sharp planing knives;
- When planing soft wood.
Otherwise there is a risk that the machine will be
overloaded. It is best to work on a workpiece in
several operations until the desired thickness is
reached.
• As the width of the workpiece increases, the chip
removal must be reduced.
• If the workpiece gets stuck, lift the planer approx. 1
mm (1/2 crank turn). Plane the workpiece along the
grain if possible.
• The surface quality is better if less material is re-
moved in multiple passes.
• Switch the machine off if work is not going to contin-
ue immediately.
• Workpieces that are shorter than 152 mm must not
be processed.
• Plane a maximum of 2 workpieces at a time. Feed at
both outer edges.
• Use the push stick for small workpieces.
