either through the right (5.3) or left (5.4) opening.
A chip collection bag or extraction hose (dia. 36
mm) can be connected at both openings.
Chip collecting bag SB-HL (accessories)
The chip collecting bag is secured via adapter
AD-HL (5.6). The adapter is attached by fl ap (5.5)
to the lower edge of the chip removal opening and
screwed in by means of rotary button (5.7) in the
tapped bore (5.1).
Extraction hose
An extraction hose (dia. 36 mm) can either be fi t-
ted directly in the chip removal opening, or in the
adapter AD-HL for the chip collecting bag.
6 Putting the planer down
When working with electric planers you must
remember that the planer shaft continues to run
for a few seconds after the tool is switched off.
The HL 850 EB has a support foot (2.8) at the end
of the platen so that it can be placed safely on a
work surface. If the electric tool is taken up, the
support foot automatically protrudes beyond the
planer platen to ensure that the planer shaft is
always raised above fl at work surfaces when the
planer is put down.
Pay attention to the following when put-
ting the HL 850 EB down:
- check that the support foot is present and fully
operational,
- wait until the planer shaft comes to a standstill
before putting the tool down.
If the support foot should be found obstructive
during special planing work it can be swung back
out of the way and locked in position (2.8).
7 Working with the machine
The surface to be planed must be free of
metallic objects.
Always secure the workpiece in such a
manner that it cannot move while being
sawed.
The machine must always be held with
both hands by the designated handles
(1.3, 1.7).
Procedure
- First set The desired chip thickness.
- Place The front platen onto The workpiece but do
not allow The planer head to come into contact
with The wood.
- Switch on the planer.
- Guide The planer over The workpiece so that The
platen rests fl at on The workpiece. Press on The
front planer platen when starting to plane and
on The rear planer platen (end of workpiece)
when continuing or fi nishing planing.
7.1 Rebating
The planer can rebate to an unlimited depth.
To do this, fold away the protective cover (2.5)
by fi rst pushing the lever (1.5) forward and then
laterally to the left. The front of the planer head
is now exposed.
When work is completed, the protective cover
moves back automatically to initial position
through spring force.
7.2 Chamfering
The front planer platen is equipped with a 90° V
groove (2.12) to allow the chamfering of workpiece
edges. This V groove is 2 mm deep, thus produc-
ing a 2 mm edge chamfer with the chip thickness
setting 0.
7.3 Bench-mounted operation
The planer can be operated bench-mounted in
conjunction with the bench-mounting device
SE-HL. Detailed instructions are supplied with
the accessories.
7.4 Rustic planer heads (accessories)
The planer can also be used to create rustic sur-
faces. Three rustic planer heads are available for
this purpose:
- HK 82 RG: creates a surface with a coarse struc-
ture.
- HK 82 RG: creates a surface with a fi ne struc-
ture.
- HK 82 RW: creates an uneven, wavy surface.
The blades on the rustic planing head (HK
82 RF, HK 82 RG, HK 82 RW) protrude ap-
prox. 1.5 mm over the planer foot.
When using rustic planing heads on the planer,
set the cutting depth to 0 mm. Otherwise there is
a risk that the blades on the head will cut into the
planer foot and destroy the planer.
The cutting depth limiter (6.2) prevents the cutting
depth from increasing inadvertently while planing
work is performed.
Always attach the cutting depth limiter to the
planer before working with a rustic planing
head:
- Set the cutting depth on the planer to 0 mm,
- Attach the cutting depth limiter by inserting the
