No scratch and melting shall be made to covered lead~wires of an
ac. primary circuit including mains leads.
No illegibility shall be given to the specification plate, the cau-
tion labels, the fuse labels and others.
When, on pattern sides of circuit boards, additional repair-parts
have been made up, the parts shall be firmly glued to circuit
boards or other components, unless the parts can be attached
firmly.
The following matters shall be maintained as they are, when
repairing.
1) Soldering of lead-wire ends

' Care should be taken of the space distance In an ac. pri-

mary circuit as well as soldering.

2) Wiring and holding of leadwires With Wire-clips and binders
3) Materials of lead-Wires

e.g.; For UL models, lead-Wires to be used shall be ap~

proved or accepted by the UL.

a) Location of all kinds of insulators
5) Setting of voltage selector switch

Set the Voltage Selector Switch to 240V. 220V, or 120V,

According to your Local Voltage.

,After repaired, the insulation resistance or leakage current shall

be measured with 500 : 5V 0.8 and shall be not less than 1M0.

Follow the instructions carefully, which will allow the user to optimise the products'
performance and give many years of serivce.

6. General instructions for mechanism repair

H The heads, caostan and punch roller shall be cleaned of good
quality alcohol after renalred, because dirty heads shall cause
distorted sounds while dirty caustan and pinch roller shall
occur wow/flutter and take-up fault,

Lubricants been stained the surfaces oi transmitting portion
of the belts, idlers, capstan and pinch roller shall he removed,
because slippery and laulty tape travel shall be caused.

When oiling, only one or two drops shall be applied so as
not to run over and be dispersed. Note should be taken ol the
metal fitting for the capstan and rotating portions of the
idlers and pinch roller, especially.

Errings and poly slider washers shall be replaced With new
ones, it once those have been removed. - No reutillzatlon
due to unreliability.

Regular spare-parts shall always be used lor repair, because
using irregular parts and tampering With the products shall
