Operation
Tips and notes on handling the belt sander
General information:
•
Only use abrasive belts which are approved for the device
used.
•
Before every application, make sure that you have selected
the correct abrasive belt for the intended use. A coarse grit
is suited for rough grinding, a fine grain size, on the other
hand, is more appropriate for fine and finish grinding.
•
Do not process wood and metal using the same abrasive
belt.
•
Only use intact, flawless abrasive belts. Damaged abrasive
belts could tear and cause damage to the workpiece.
Exchange abrasive belts in due time.
•
Make sure that the abrasive belt does not grind into the
housing.
•
Clamp the workpiece unless it is firmly and safely
positioned by its own weight.
•
Do not overload the device so that it comes to a standstill.
•
Keep the venting slots clear to prevent the motor from
overheating.
•
Only store abrasive belts in a suspended position, as they
are damaged by kinks and the likes.
Sanding:
•
Belt speed and grain size of the abrasive belt define the
removal rate and the surface finish.
•
For grinding off untreated wooden surfaces move the
device in a straight line along with the grain. That way you
can prevent transverse sanding marks. For sanding other
surfaces move the device in ovals. Always sand in parallel
to the grinding path ensuring an appropriate overlap.
•
Do not apply excessive contact pressure. The device's own
weight achieves a sufficient grinding performance
resulting in smoother workpieces surfaces. Increased
contact pressure leads to a greater wear of the device and
the abrasive belt.
•
If the material's surface is untreated, start grinding with
coarse or medium grain size and finish off with a fine grit.
•
Best use a coarse grain size (40 or 60 grit) for removing
paint and for rough grinding particularly raw wood. For
surface-grinding undressed or sawn timber use abrasive
belts of medium grit (grain size 80, 100 or 120). Use a fine
grit (grain size 180, 240 or 320) to smoothen and fine-
grind timber and surfaces coated with old paint as well as
for dry sanding untreated wooden surfaces.
•
Use a dust extraction system when grinding off residual
paint. Paint residues might smelt and then smudge both
workpiece and abrasive belt.
•
Switch the device on before applying it to the workpiece.
Once the grinding process is concluded, lift the device off
the workpiece before you switch it off.
•
Do not attempt to slow down the petering out abrasive belt
by pressing against it.
