Operation - Scheppach HMS850 Translation From The Original Instructions

9. Operation

m IMPORTANT!: The surfacing and thicknessing
plane has been specially designed for planing solid
wood. High alloy knives (21) are used for this pur-
pose. The contact surface of the workpiece must be
flat for thicknessing. If you want to work on large or
heavy workpieces, the machine must be secured in
place (e.g. using the thread in the machine base).
• The ON/OFF switch (1) is on the left-hand side of
the machine. Press the green key "I" to switch on
the machine. Press the red key "0" to switch off
the machine.
• The machine is fitted with an overload switch (35)
to protect the motor. In the event of an overload,
the machine will cut out automatically. After a
short time, the overload switch (35) can be reset
again.
• To work on long workpieces, use roller tables or
a similar supporting arrangement. Such optional
units are available from your local DIY stores.
They must be placed at the entry and exit ends of
the plane. Their height must be adjusted such that
the workpiece is horizontal when it is fed into and
out of the machine.
9.1 Surfacing
m IMPORTANT!: Pull out the power plug before
performing any maintenance, cleaning and adjusting
work.
9.1.1 Adjustment (Figure 1/3/5)
• Turn the adjustment knob for cutting depth (11) to
set the height of the feed table (13). The set cutting
depth can be read off the scale (18).
• Loosen the parallel stop (6) with the clamp lever
(7). Set the required angle. The set angle can be
read off the scale (38). Secure the parallel stop (6)
with the clamp lever (7) again after making the set-
ting.
9.1.2 Fitting the chip extractor (Figure 6-8/16)
• Fit the hand crank (4) to the post on the planing ta-
ble (14). Turn the hand crank (4) counter-clockwise
to move the thicknessing table (20) to its lowest
position.
• Place the chip extractor (5) on the thicknessing
table (20).
• Turn the crank handle (4) clockwise until the chip
extractor (5) is firmly secure and the recess (C) is
on the safety switch (D2).
• Attach the extraction system adapter Ø 100 mm
(27) to the connection for a sawdust extractor (5).
• Connect the plane to a chip extraction system (not
supplied).
9.1.3 Surfacing mode (Figure 9/10)
• Undo the locking knob (32) and move the planing
knife cover (12) as far as necessary to accom-
modate the width of the workpiece. Re-tighten the
locking knob (32).
• Connect the mains plug to the mains lead. Press
the green button "I" to start the plane (1).

• Place the workpiece you wish to plane on the
feed table (13). Hold the slide blocks (2) with both
hands and slide the workpiece forwards towards
the planing table (14) over the knives (21).
• When you have finished work, switch off the
machine. To do this, press the red button "0". Then
disconnect the machine from the mains supply.
• Remove the chips and dust from the feed table
(13), planing table (14) and knife block (23) after
the machine has reached a complete standstill.
• Return the planing knife cover (12) to its original
position.
9.2 Thicknessing
m IMPORTANT!: Pull out the power plug before
performing any maintenance, cleaning and adjusting
work.
9.2.1 Adjustment (Figure 13)
Place the hand crank (4) on the post on the planing
table (14) and turn it to adjust the thicknessing table
(20) to the required height. The set angle can be
read off the scale (29).
9.2.2 Fitting the chip extractor
(Figure 8, 11-13, 16)
• Undo the locking knob (32) and pull the planing
knife cover (12) forwards as far as possible.
• Place the chip extractor (5) on the planing table
(14). Ensure that the stop pins and the securing
screw (34) are in the appropriate holes and are
engaged in the internal threads on the planing
table (14) and that the recess (B) is on the safety
switch (D1).
• Turn the securing screw (34) until the chip extrac-
tor (5) is secure.
• Attach the extraction system adapter Ø 100 mm
(27) to the connection for a sawdust extractor (5).
• Connect the plane to a chip extraction system (not
supplied).
9.2.3 Thicknessing mode (Figure 11/13/17)
• Connect the mains plug to the mains lead. Press
the green button "I" to start the plane.
• Place a workpiece on the thicknessing table (20).
Guide the workpiece towards the feed table (13).
• When you have finished work, switch off the
machine. To do this, press the red button "0". Then
disconnect the machine from the mains supply.
• Remove the chips and dust from the thicknessing
table (20) and knife block (23) after the machine
has reached a complete standstill.
• Use the pull-out workpiece support for long work-
pieces.
9.3 Changing the knives (Figure 17/18)
• m IMPORTANT!: Always pull the mains plug
before changing the knives.
• Remove the parallel stop following the instruc-
tions in 8.2 in reverse.
• Pull the planing knife cover (12) forwards as far
as possible so that the entire knife block (23) is
exposed.
