Notes on the motor
⇑
The normal operating speed of this sewing ma-
chine is 1,300 stitches per minute, which is quite
fast compared to the normal operating speed of
300 to 800 stitches per minute for the ordinary
foot-operated sewing machine.
⇑
The bearings in the motor are made of a special
sintered, oil-impregnated alloy mounted in oil-
soaked felt to withstand long hours of continuous
operation.
⇑
Continuous operation of the sewing machine can
cause heat to build in the motor area, but not
enough to adversely affect its performance.
It is important to keep fabric and paper away from
the ventilating holes on the back and sides of the
machine so air can get to these holes.
⇑
When the motor is running, sparks can be seen
through the ventilating hole in the motor bracket
on the side opposite the hand wheel. These
sparks are produced by the carbon brushes and
the commutator, and are part of the machines
normal operation.
CAUTION
WHEN THREADING THE MACHINE, RE-
PLACING A NEEDLE, OR WHEN THE MA-
CHINE IS NOT IN USE, WE RECOMMEND
DISCONNECTING THE ELECTRIC SUPPLY
PLUG TO AVOID ANY POSSIBLE HAZARDS.

Om motoren
⇑
Normal arbejdshastighed for denne symaskine
er 1300 sting i minuttet, hvilket er ret hurtigt
sammenlignet med den normale arbejds-
hastighed på 300-800 sting i minuttet for
almindelige fodbetjente symaskiner. Motorens
lejer er fremstillet af en specialsintret olie-
imprægneret legering monteret i oliebadet filt,
så de kan tåle mange timers kontinuerlig drift.
⇑
Kontinuerlig drift af symaskinen kan føre til, at
motorområdet ophedes, men ikke i så høj grad,
at ydelsen påvirkes. Det er vigtigt at holde stof
og papir på afstand af ventilationshullerne
bagpå og på siderne af maskinen, så luften kan
passere frit..
⇑
Når motoren er i gang, kan man se gnister
gennem ventilationshullet i motorophænget på
modsat side af håndhjulet. Disse gnister
fremkaldes af kulbørsterne og kommutatoren,
og er en del af maskinens normale drift.
ADVARSEL
NÅR MASKINEN TRÅDES, MAN SKIFTER
NÅL, ELLER MASKINEN IKKE ER I BRUG,
ANBEFALES DET AT TAGE STIKKET UD AF
KONTAKTEN FOR AT UNDGÅ EVENTUELLE
ULYKKER.
