General Safety Rules
WARNING – Reading the operating instructions will reduce the risk of
injury.
WARNING Read all safety warnings and all instructions. Failure to follow
the warnings and instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
Before using this power tool, carefully read through and familiarise yourself
with all the enclosed safety information and the instructions. Keep all
enclosed documentation for future reference, and pass on your power tool only
together with this documentation.
Specific Safety Rules
Pay particular attention to the parts of the text marked with this symbol for
your own safety and the protection of your power tool.
Hold power tool by insulated gripping surfaces, because the cutter head may
contact its own cord. Cutting a “live” wire may make exposed metal parts of
the power tool “live” and shock the operator.
Wait until the cutter drum is at a standstill before setting down the power
tool. An exposed cutter drum can get caught on the surface and lead to a loss
of control and possible serious injury.
Always wear personal protective equipment, safety goggles, ear protectors,
protective gloves and heavy-duty footwear during work and for all setting,
conversion and maintenance tasks!
Be aware of the risk of injury presented by the sharp
cutting edges of the reversible blades.
Be aware of the rotating cutterhead.
Remember that your paint remover’s motor, and the cutterhead with it, run on
after the tool is switched off.
Dust from material such as paint containing lead, some wood species, minerals
and metal may be harmful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood conditioning (chromate,
wood preservative). Material containing asbestos must only be treated by
specialists.
– To achieve a high level of dust collection, use a suitable Metabo vacuum
cleaner together with this tool.
– The work place must be well ventilated.
– The use of a dust mask of filter class P2 is recommended.
Follow national requirements for the materials you want to work with.
Avoid the possibility of your power tool being switched on accidentally:
Switch your power tool off every time it is disconnected from the mains supply
or if the power supply has been interrupted.
Do not process any workpiece surfaces in which nails, screws or other such
obstacles may be encountered.
Turn or replace blunt blades in good time: if the cutting edges on the blades
are blunt, there is an increased risk of kickback and the quality of the
processed surface will deteriorate.
Always turn or replace blunt blades in pairs.
Opening the protection flaps
Caution: Beware of sharp cutting edges!
Switch off machine. Milling head must be at a total standstill! 
A: Open the protection flap as
indicated and
B: fold flap up into the fully-open position.
Protection flaps
When milling plane surfaces all protection flaps must be closed. When carrying
out peripheral milling (e.g. on rebates) only open the protection flap
pointing to the workpiece.
Metabo Sautomatic safety clutch:
If the insertion tool jams or hooks, the power flow to the engine will be
restricted. Because of the high power which then arises, always hold the
machine with both hands on the handles, stand safely, and concentrate on your
work.
Operation
Before initial use, check that the mains voltage and mains frequency stated on
the rating plate match the figures for your own mains supply.
Always work with an extraction system to guarantee perfect machine operation.
Guide the machine with both hands on the handles.
6.1 Switching the paint remover On/Off
Switching on
Lift the paint remover so that the cutterhead can rotate freely. Push the
slide-switch (4) forwards.
I – switched on.
If switched on continuously, the machine continues running if it is jerked out
of your hands. Therefore, always hold the machine with both hands on the
handles, stand safely, and concentrate on your work.
Switching off
Lift the paint remover so that the cutterhead can rotate freely. Press down
the rear end of the slide-switch (4). The slide-switch springs back.
0 – switched off.
Wait until the cutter drum is at a standstill before setting down the machine.
An exposed cutter head can get caught on the surface and lead to a loss of
control and possible serious injury.
6.2 Locking the cutterhead
Be aware of the risk of injury presented by the sharp cutting edges of the
reversible blades. Do not attempt to lock the cutterhead in position until it
has come to rest. Switch the paint remover off and disconnect from the mains
supply.
Set the paint
remover down on its side.
Press the locking button (2) fully home into position and hold down.
At the same time, turn the cutterhead with the ring spanner (8a) in either
direction. Turn until the depressed locking button can be felt to engage and
the cutterhead is locked in position.
6.3 Setting the axial cutting depth
Be aware of the risk of injury presented by the sharp cutting edges of the
reversible blades. Do not attempt to set the axial cutting depth until the
cutterhead has come to rest. Switch the paint remover off and disconnect from
the mains supply.
Lock the cutterhead in position and hold down the locking button.
Set the desired cutting depth by
turning the adjuster screw with the ring spanner supplied.
Range of cutting depth: 0 – 0.3 mm.
Start off with a fine cutting depth and increase gradually until you reach the
ideal cutting depth for the material being processed.
Remember to remove the ring spanner!
6.4 Fitting/removing the extraction device adapter
For dust extraction purposes use a Metabo suction unit or some other suitable
extraction device.
Fitting
Push the extraction device adapter (6) into the extraction nozzle (5) until it
engages in position.
The required extraction device can now be connected to the 35 mm dia. tube
adapter.
Removing
Press in the tongue and pull the adapter (6) out of the extraction nozzle (5).
Tips and Tricks
7.1 Guiding the paint remover
Always use two hands to guide the paint remover backwards where possible over
the surface of the workpiece being processed.
When holding the paint remover down, ensure that the pressure exerted is
distributed evenly over the area of the planing base.
7.2 Presenting the tool to the edge of a workpiece See diagram A: Hold
the paint remover parallel with the surface of the workpiece. When presenting
the tool, ensure that the planing base is in contact with the largest possible
area of the surface.
7.3 Procedure
See
diagram B: Guide the paint remover in such a way that the planing base (9) is
always positioned on the surface that has not yet been processed. If you
proceed as shown, a narrow section is left over.
See diagram C: You can remove this section by setting the cutting depth to 0
mm (see section 6.3) and now always guide the planing base over the processed
surface.
7.4 Smoothing
Reduce the cutting depth to achieve a smooth surface finish.
Maintenance
Be aware of the risk of injury presented by the sharp cutting edges of the
reversible blades. Do not attempt any maintenance operation until the
cutterhead has come to rest. Switch the paint remover off and disconnect from
the mains supply.
Always wear personal protective equipment, safety goggles, ear protectors,
protective gloves and heavy-duty footwear during work and for all setting,
conversion and maintenance tasks!
8.1 Cleaning the reversible blades
Paint, etc. can lodge under the cutting edges of the reversible blades. If
this occurs, clear the cutting edges of the blades with the sharp- pointed
tool.
8.2 Turning/replacing the reversible blades
Use original Metabo reversible blades only.
Order No.: 6.31720 (4 units)
Order No.: 6.31660 (10 units)
Blunt blades increase the risk of the paint remover jamming and kicking back
off line during operation. To avoid this, turn or replace blunt reversible
blades in good time.
Scrape clean the Torx heads of the screws securing the
reversible blades using the sharppointed tool (7).
Axial reversible blades:
Lock the cutterhead in position.
Set the paint remover down on its side and release the locking button.
Remove the ring spanner (8a) and reverse it (8b, Torx).
Press the locking button (2) fully home and
hold down.
Radial reversible blades: Open protection flap. Turn milling head with special
Allen key until cutting blade is accessible.
Turn out the screws securing the reversible blades (10) with the Torx spanner
(8b).
Detach the reversible blades (10) using the sharp-pointed tool and clean the
contact surface of the blades.
Replace the reversible blades (10) so that the blades once again present a
sharp edge as they rotate.
If all of the cutting edges are worn blunt, replace the reversible blades.
Always turn or replace both reversible blades at the same time.
Replace and screws with damaged Torx heads.
Apply a torque of 5 Nm to secure reversible blades after turning or
replacement.
Do not forget to remove the Torx spanner!
8.3 Cleaning the cutterhead and contact surface of the planing base
If the cutterhead requires cleaning, use a cleaning material suitable for use
with aluminium (pH value between 4.5 and 8).
8.4 Cleaning the vacuum extraction nozzle
During operation it is possible that chips may lodge in the extraction
nozzle and block it. Insert the sharp-pointed tool (7) into the cleaning slit
in the extraction nozzle to loosen and remove any chips causing a blockage.
Remove the extraction nozzle (5), if necessary. To remove, turn out the cross-
head screws and pull the extraction nozzle out to the rear. Clean the
extraction nozzle and the planing base (9).

P 1 = rated input
P 2 = output power
Vibration total value (vector sum of three directions) determined in
accordance with EN 60745:
a h = Vibration emission value (Planing soft wood)
K h = Uncertainty (vibration)
The vibration emission level given in this information sheet has been measured
in accordance with a standardised test given in EN 60745 and may be used to
compare one tool with another. It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents the main applications of the
tool. However if the tool is used for different applications, with different
accessories or poorly maintained, the vibration emission may differ. This may
significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into
account the times when the tool is switched off or when it is running but not
actually doing the job. This may significantly reduce the exposure level over
the total working period.
Identify additional safety measures to protect the operator from the effects
of vibration such as: maintain the tool and the accessories, keep the hands
warm, organisation of work patterns.
Typical A effective perceived sound levels:
L pA = Sound pressure level
L WA = Acoustic power level
