Tools and necessary accessories
To service and repair any type of sewing machine efficiently, the
mechanic should have available proper tools and several
accessories, essential for a good maintenance job. He must
know how to operate the machine and be familiar with the various
mechanisms of the machine and the manner in which they are
adjusted (timed). Finally, he must be scrupulous about cleaning
the machine and oiling all the parts which require lubrication.
For the mechanics we have available a tool kit containing all
wrenches screw drivers and gauges for any repair and timing of
the SUPERNOVA machine.
Suggestions for the mechanics
After a short examination of the machine, a good mechanic will
be able to state with certainty whether the machine sews correctly
or not and, consequently, whether repairs are required. Many
times a customer calls in a mechanic to have a machine repaired
which supposedly is out of order. Quite often the customer
attributes the poor performance of the machine to imaginary
defects of some of the sewing machine parts, while in reality the
trouble lies in the customer's own lack of experience in using the
machine.
There are four fundamental questions every mechanic should ask
in investigating the customer's knowledge with regard to the
machine:
Does the customer know what type and size of needle to use
and
how to insert the needle in the machine?
Does the customer know how to thread the machine correctly?
Does the customer know how to clean the shuttle race?
Does the customer know how to judge the tensions of upper
and lower thread and how to adjust these tensions, if
necessary?
