Notes for service engineers
If the machine does not run perfectly and has not been
used for a long period of time, run the oiled machine at
high speed for about a minute with the front fl ap closed.
Do not forget to fi rst sew on a fabric scrap to absorb any
leaked oil.
TIP
These parts of the machine may need to be oiled more
frequently, depending on how often you use the
machine.

Tensioning the V-belt
NOTICE!
Risk of damage!
The motor or machine may be damaged if the V-belt is
too tight or too loose.
− Always have the V-belt tension adjusted by a specialist.
1. Undo the screw on the underside of the machine.
2. Open the side cover.
3. Loosen the two screws indicated in the diagram opposite,
turning each screw one revolution.
4. The motor unit can now be moved up or down in order to
adjust the tension.
Please note that the V-belt must have an allowance for
clearance of 10 mm (or 3/8").
5. Tighten the two screws again.
6. Close the side cover and screw it back on.
