ENGLISH
Operation without a dust collector is only
advisable:
− outdoors;
− for short-term operation
(up to a maximum of 30 minutes);
− when wearing a dust respirator.
If no dust collector is used chips will built
up inside the machine housing, and on
the planer knives in particular. These
built-up chips cause the planed surface
to become rough. Therefore the chips
need to be removed periodically.
A
Danger!
The rotation of the cutterblock
causes the chips to be blown through
the slot in the cutterblock cover.
A
Caution!
The slot of the cutterblock
cover or an installed dust extraction
connector must not be blocked by
objects placed in the path of ejected
chips.
Installing the dust extraction connec-
tor
A
Cutting hazard when touching
the rotating cutterblock!
Accidental starting of the machine
may cause serious injury.
Unplug power supply cable before
installing the dust extraction connec
-
tor!
1. Set lock lever fully to the left, into the
position marked
.
2. Lower cutterblock head, until the
screws (49) of the cutterblock cover
are easily accessible.
3. Loosen screws (49), until the dust
extraction connector can be put on.
4. Attach the dust extraction port (48)
on the cutterblock cover, so that the
upper recesses fit under the screws
of the cutterblock cover.
5. Screw holding pins (51) in the
mounting holes (50) and tighten
hand-tight. The dust extraction con-
nector shall rest securely on the
holding pins.
6. Retighten the screws (49) of the cut-
terblock cover.
6.4 Mains Connection
B
Danger! High voltage
• Operate this machine in dry sur-
roundings only.
• Operate the machine only on a
power source meeting the follow
-
ing requirements (see also "Tech-
nical specifications"):
− outlets properly installed,
earthed, and tested.
− mains voltage and system fre-
quency conforming to the volt-
age and frequency shown on
the machine´s rating label;
− fuse protection by a residual
current operated device (RCD)
of 30
mA sensitivity;
− System impedance Z
max
at the
interconnection point (house
service connection) 0.35 Ohm
maximum.

Note:
Check with your local Electric-
ity Board or electrician if in doubt
whether your house service connec
-
tion meets these requirements.
• Position power supply cable so it
does not interfere with the work
and is not damaged.
• Protect power supply cable from
heat, aggressive liquids and
sharp edges.
• Use only rubber-jacketed exten-
sion cables of sufficient lead
cross-section (see "Technical
specifications").
• Do not pull on power supply
cable to unplug.
A
Danger!
• This machine may only be oper-
ated by one person at a time.
Other persons shall stay only at a
distance to the machine for the
purpose of feeding or removing
stock.
• Use personal protection gear:
− dust respirator;
− hearing protection;
− safety goggles.
• Before starting work, check to
see that the following are in
proper working order:
− power cable and plug;
− ON/OFF switch
− cutterblock cover
− push stick.
• Assume proper operating posi-
tion when thicknessing:
− at the front of the machine;
− to the side of the infeed table;
− when working with two per-
sons, the second person must
stay at a sufficient distance to
the thicknessing machine and
stand to the side of the infeed
or outfeed table, respectively.
• If the type of work requires, use
the following:
− work piece support (e.g. roller
support) – to keep the machine
from tipping over when work
-
ing long work pieces;
− push stick (feeding aid) – for
short work pieces;
− dust collector;
− sliding wax – to enhance glid-
ing of the work pieces through
the machine, apply a light coat
of sliding wax to the surfaces
of infeed and outfeed table.
• Avoid typical operator mistakes:
− Do not exceed the specified
work piece dimensions.
− Do not jam the work piece.
Risk of kickback.
Before planing a work piece
Test the machine when idling:
1. Fold down both infeed and outfeed
table.
2. Make sure the planer knives can
turn freely.
3. Set lock lever fully to the left, into the
position marked
.
4. Raise cutterblock head to at least
1 inch (25 mm) planing thickness.
5. Set lock lever fully to the right, to the
position marked
.
6. Plug in the power supply cable's
plug and start the motor (press
green switch button).
7. Once the machine has reached full
speed, pay attention to:
− noise
− vibrations
A
Danger!
If noise and/or vibrations appear
to be unusually high: turn OFF the
machine immediately and unplug!
8. Check machine for parts that may
have worked loose; fasten any loose
parts properly, where necessary.
7.1 Planing Work Pieces
The thickness planer can remove a max-
imum of 1/8" (3 mm) in a single pass.
However, this depth of cut may be used
only:
− with very sharp planer knives;
− when planing soft wood;
