Mounting Of The Hose Connector; Change And Adjustment Of Knives; Operation; Switching On And Off - Mafell MHU 82 Betriebsanleitung

Note:
German TRGS 553 «wood dust» requires the use of
tested extraction devices. When using other equip-
ment, industrial users must ascertain any special
requirements by consulting the relevant liability
insurance association.
The portable electric plane will remain within the
technical guideline value for wood dust concentration
(2 mg/m³) only if connected to a tested extractor unit.

5.3 Mounting of the hose connector

Enclosed screws with spacer sleeves are to be
screwed into the housing below the connecting piece
of the chip ejector. Attach hose connector until
snap-on cap locks.

5.4 Change and adjustment of knives

Caution!
Before doing this kind of work pull out the
mains plug.
Loosen handle screw 6, adjust rabbet depth stop to
full rabbeting depth. Loosen pressure screws 17,
remove knife 19 laterally, turn it over, insert it again
and align it laterally with front and rear support.
Tighten pressure screws (8.4 Nm).
When using profile knives attention has to be paid
that the profile of knife and clamping device corre-
sponds, in order to obtain a satifactory surface.
The height of the profile knives can be adjusted by
means of the adjusting screws 18.
The cutter head, clamping devices, knife supports
and knives have to be cleaned when turning or ex-
changing them – see paragraph 7. (Maintenance).

Operation

6.1 Switching on and off

To switch on the machine, hold down the starting
lock-off button 3 and press switch 2. Since this is
not a latching switch, the motor runs only as long
as the switch is pressed down.
To switch off, release switch 2. The starting lock-off
button prevent the machine from being switched on
accidentally.
Caution!
Do not switch on the machine if the cutter head
is touching the workpiece.

6.2 Adjusting cutting depth

Turn button for adjusting cutting depth 4 to cutting
depth desired according to scale 21.
6.3 Operating instructions
The plane can be guided well with handle 1. Please
pay attention that the front support of the plane
rests well on the wood.
When using profile knives, adjust cutting depth to «0».

6.4 Rabbeting

Loosen handle screw 6, adjust rabbet depth stop 7
to depth required and fasten handle screw again.
After rabbeting loosen handle screw 6 and put rab-
bet depth stop to normal position so that the cutter
head is covered laterally.
For rabbeting, the angle fence 033 096 (optional
accessory) should be used.

Maintenance

The portable electric plane MHU 82 is designed with
a low maintenance requirement. The ball bearings
are greased for life.
The machine must be regularly cleaned of dust, at
the same time blowing out the motor ventilation
apertures.
The cutter head, clamping devices, knife supports and
knives used on the machine must be freed from resin
regularly as a clean tool improves the cutting quality.
This can be done by soaking the clamping devices,
knife supports and knives for 24 hours in paraffin,
white spirit or commercially available resin remover.
Tools made of aluminium may only be deresi-
nified with cleaning agents which do not corro-
de this kind of material.
After a prolonged period of operation, users are
recommended to have the machine checked by an
authorized MAFELL customer service agency.
