F - MAINTENANCE
1.4. It is inevitable to clean and check the needle bars as often as possible - follow this pro-
cedure:
- Switch off the machine, take out the needle.
- Loosen the screw of the needle bar guard
, turn the needle bar anti-clockwise and push
it out of its guard.
- Loosen the nut with the wrench.
- Take out the securing ring from the needle bar groove and push out the pin . Slowly
take out the set from the case in upward direction. Mind the balls .
- Take out the pin , this releases the bar and you can push out the insert .
- Remove the eventual damaged parts of the spring and needle from the piston . Clean
the piston , check its edges and polish the possible wear. If it is not possible to clean its
opening, replace the piston because it can damage the needle tip in the piston opening.
- Clean all the demounted parts, wash them with petrol, clean with the brush, and spread
little oil on it. The piston in the case
must move easily! Put a new spring into
the piston and put it in the guide . It must
be pushed there easily!
- Put in the spring
and push the bar into
the guide - secure it with a pin .
- Slide the set into the case with the bevel
in backward direction, i.e., against the lock
. Partially insert the balls and pull the case
up to the edge of set´s bevel.
- Push in the pin with its flat surface fac-
ing the spring and secure it with a securing
ring . Mount the nut . Put the needle bar
into the ma chine and tighten the screw .
In a similar way check the lower needle bar after
you have unmounted the lower looper cover. The
lower looper should be on the right side.
