Transport
Improper transport is prone to accidents and can cause
damage or malfunctions to the machine, for which we do
not provide any liability or guarantee.
Transport the scope of delivery secured against shifting
or tipping with a sufficiently dimensioned industrial truck
or a crane to the installation site.
General hazards during internal transport
Machines may only be transported by authorized and
qualified persons. Act responsibly when transporting and
always consider the consequences. Refrain from daring
and risky actions.
Inclines and slopes are particularly dangerous (e.g.
driveways, ramps and the like). If it is unavoidable to
drive on such passages, special care is required.
Before starting the transport, check the transport route
for possible hazards, bumps and imperfections as well
as sufficient strength and load-bearing capacity.
Hazardous areas, bumps and imperfections must be in-
spected prior to transport. The removal of hazardous
areas, bumps and obstructions at the time of transport by
other employees leads to considerable dangers.
Careful planning of internal transport is therefore essen-
tial.
Transport with a fork ift / pa et truck:
For shipping, the device is firmly mounted on a pallet so
that it can be transported with a forklift or a pallet truck.
5.2 Packaging
All used packaging materials and packaging aids are re-
cyclable and should be taken to a materials recycling de-
pot to be disposed of.
The delivery packaging is made of cardboard, so please
dispose carefully by having it chopped up and given to
the recycling collection
The film is made of polyethylene (PE) and the cushioned
parts of polystyrene (PS). Deliver these substances to a
collection point for recyclable materials or to the compe-
tent waste disposal company.

8.1 Genera informations
Before each start of work, the fo owing tests must be
carried out:
- Check all cables and plugs.
- Check that the workpiece supports are aligned and
tightened.
- Note that there are different grit sizes for different
jobs.
- Before starting the machine, make sure that the
sanding belt is free to rotate and that it is not
braked or blocked by any workpieces.
- Lubricate regularly according to item maintenance.
- Before commissioning, the center run of the
grinding be t must a ways be checked by man-
ua feed!
8.2 Surface-grinding on the sanding
be t
Check that the workpiece stop Pos. 7 in figure 4 is cor-
rectly mounted and tightened. Open the hinged cover
Pos.4 on figure 4. Switch on the belt sander and carefully
press the workpiece with both hands against the sanding
belt and the safety stop. For better material removal and
even belt wear, the workpiece can be easily moved back
and forth.
8.3 Grinding on the workpiece support
Hold the workpiece firmly with both hands. Grind internal
curves only on the front workpiece support.
8.4 Connection for connecting of an
extraction system
On the chip box Pos. 6 (Figure 4) and the back of the belt
grinder is a 100 mm Ø connecting piece for connection
to an extraction system.
9 Notes for the grinding pro-
cess
- When grinding, pay attention to the safety instruc-
tions and use the protective devices on the ma-
chine as well as your personal protective equip-
ment (protective goggles, ear protection, safety
shoes, etc.).
ATTENTION!
The grain size of the abrasives must be selected
according to the requirements.
NOTE!
After switching the belt speed, the run of the sanding
belt must be checked and, if necessary, readjusted.
ATTENTION!
Rotating parts! Get to work with reason. Pay atten-
tion to what you do. Pay special attention to the rotat-
ing parts. Wear tight-fitting clothing. Make sure that
hair or clothing is not caught by rotating parts! Wear
a hairnet. When working with the machine no jewelry
may be worn.
ATTENTION!
Risk of injury!
Flying chips and slinging away parts! Be sure to wear
safety glasses! Protect your eyes from flying chips
and other splinters.

ATTENTION!
Do not work with too much pressure, otherwise the
sanding belt wears too fast. Do not put your fingers in
contact with the sanding belt.
ATTENTION!
The edge of the workpiece supports must be posi-
tioned so that a distance of max. 1 mm is present to
prevent jamming of workpieces or fingers between
the table and the sanding belt.

C eaning, maintenance and service
- Special reference to situations that may cause
damage to persons, the machine and / or the envi-
ronment or may lead to financial loss.
- Make sure that the gap between the work table and
the grinding wheel is not too large. Especially with
thin workpieces, there is a risk that the workpiece
will enter the gap!
- Since the machine does not have a clamping facil-
ity, it is important that your workpiece rest on the
worktable over the entire surface and be held tight!
- Make sure the abrasives are in good condition and
replace worn out abrasives in a timely manner.
Only with perfect tools you can achieve a good
grinding quality!
10 C eaning, maintenance and
service
Oil, grease and cleaning agents are hazardous to the en-
vironment and must not be disposed of in wastewater or
normal household waste.
10.1 C eaning
Basically, the machine should be cleaned after each use.
With the machine off, remove the chips and dust from
the cooling openings of the motor with a hand brush or
brush. Cleaning with compressed air is not allowed, as
the fine chips can easily fly into the eyes and cause inju-
ries.
For the disposa of the chips we refer to the oca
regu ations.
10.2 Maintenance
Empty the spark arrester regularly and check whether
the suction channel has to be cleaned. If the edges of the
contact wheel are rounded or the surface is damaged,
replace the contact wheel immediately. Replace the
graphite sanding pad on the plant table depending on
the degree of wear.
10.3 Service
As a result of wear and tear, it may happen that mainte-
nance work must be carried out on the machine.
10.4 Storage
Store the machine in a dry, clean, dust- and frost-free
environment. It must not be placed in a room with highly
oxidizing chemicals.
11 Disturbances, possib e
causes and measures
WARNING!
Always disconnect the machine from the power sup-
ply before starting any cleaning, maintenance or ser-
vicing work!
ATTENTION!
Risk of injury!
Do not remove the chips with bare hands. There is a
danger of cuts due to sharp-edged chips!
Dispose of these funds in an environmentally
friendly way. The cleaning cloths soaked in
oil, grease or detergent are easily
combustible. Collect the cleaning rags or
cleaning wool in a suitable, closed container
and dispose of them in an environmentally
friendly way - do not throw them in
household waste!
WARNING!
Repairs or maintenance work may only be carried
out by qualified and trained specialist personnel.
ATTENTION!
If one of the following errors occurs, stop working
with the machine immediately. Before you begin trou-
bleshooting, turn off the machine and unplug the
power cord. It could lead to serious injuries. All
repairs or replacement work may only be carried out
by qualified and trained specialist personnel.
NOTE!
If you can not solve the problems with your machine
yourself, then please contact your nearest
METALLKRAFT dealer. Please write down the follow-
ing information from the machine or the operating in-
structions in advance to help you with your problem in
the best possible way.
