Working Instructions; Electrical Connection - Scheppach PLM1800 Translation Of Original Instruction Manual

10.2 Cutting depth measurement (14) (Fig. 14)
• The thickness planer is equipped with cutting
depth measurement (14). The pointer on the cut-
ting depth measurement (14) shows the cutting
depth when the workpiece is positioned between
this and the planer, for adjusting to the desired
planing thickness.
• The cutting depth must not exceed 0.8 mm. The
workpiece must be planed multiple times to reach
the thickness, if necessary. Check the measure-
ment with a calliper (not included in the scope of
delivery), if necessary.
10.3 Operating the thickness planer (Fig. 15)
• Connect the mains plug using the mains cable (19).
• Press the green "I" button on the on/off switch (18) to
start the planing machine.
• Place a workpiece on the feed table (12).
• To feed the workpiece into the machine, stand side-
ways next to the feed opening. Guide the workpiece in
the direction of the planing table (15).
• Slide in the workpiece slowly and in a straight line. The
workpiece is automatically drawn in. Guide the work-
piece in a straight line through the planing machine.
• To remove the workpiece from the machine, stand side-
ways next to the discharge table. Support long work-
pieces with roller blocks.
• Switch off the machine after work is complete. To do
this, press the red "0" button on the on/off switch (18).
Then, disconnect the machine from the mains.
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 delivery) 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 suc-
tion 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
adjustment 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 plan-
ing blades.
• Remove the 6 planing blade (36) screw fittings us-
ing 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 po-
sition. 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 turn-
ing the planing shaft (40).
• Fit the planing shaft cover (34) and the suction
hose (27) in reverse order after changing the plan-
ing blade.
10.6 Changing the carbon brushes (fig. 20)
m ATTENTION! Disconnect the mains plug
before carrying out any maintenance, cleaning or
adjustment 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)
Always replace in pairs.

11. Working instructions

• Only work with sharp planing blades!
• Insert the workpiece with the thicker end first, hol-
low side at the bottom.
• Chip take-off max. 0.8 mm. 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 con-
tinue 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.

12. Electrical Connection

The electric motor is connected in a ready-to-oper-
ate state. The connection corresponds to the relevant
VDE and DIN regulations.
