2-1: PRECAUTTONS
1.ElKl "N" seriqs
projectorshavebeendesigned
for the ultirnate in simplicity andease
of seryice
and repair. Eaeh screw is very impcrtant, and
when servicingor re-assembling
th€ projector,
scfaw$should not b€ omittd or carelesslyfost.
All screwsshould be firmly tightened
to assure
rel
iableprojector operation after re-assembly
-
?.When lubricating the projector's plastie parts,
siliconoil or grease shouldbeus€d.Othertypes
of lubricants may harm plastic partr. Avoid
using any solventssuch as Trichloroethylene,
whichwill harmrnost
plastic
or painted
parts.
3.EIKI projectcrs require
a minimum of special
tsols. The mort important is an ordinary l5O
Phillips
screw
drivers€t.
4. To avoid damageto screwheads,it isimportant
to remember
the adage
"70% push,3096
turn."
It isalsoirnportantto selectthe right size
screw
driverblade.A rule of thurnb isto usethe largest
blade
possible.
5.To avaid possible
electricalshock, always
dis-
connect the proiector from the power source
when
servicing.
?.?: TffiLS AND TEST EQUIPM€NT
A. Tools:
When servicingElKt "N" series,
ordinary
ISO {Phillips
type}screwdrivers
andsingle-
bladed scr'evrdrivers should be enough.
(ElKl screwdriverkits,PlN5615
areavaila-
ble-) A Malex extractor taol is most useful
whenreplacing
the pins of Nylon connectors
to the transformeror motcr,
B. Speciallcols:
ElKl "N" serieshavebeen
designed
so that
no specialtools are requiredto servicethe
projector. However,a common elaw protru-
sion gauge {Tool No- 32O{1T} is most
helpful for accurately setting the claw pro-
trusion.Standard
16mmfilm maybeusedas
a thicknessgauge where n€cessary-
{Most
filrnisabout0.l5mmor -005"
