NOTE: The main device controlled by the timer may be
restricted to operating on a more limited electrical supply
range. Check the device carefully to ensure compatibility
with your electrical supply.
Current. timer. mode. is. indicated. by. the. four. red. LEDs. on. the.
timer.face:
•. A.=.MMSS.(99min:59sec.x.1sec).
•. B.=.HHMM.(99hr:59min.x.1min).
•. C.=.SSSS. (9999sec.x.1sec).
•. D.=.MMMM.(9999min.x.1min)
(H. is. for. hours,. M. for. minutes,. and. S. for. seconds.). To. adjust.
the.timer.mode,.press.and.hold.both.the.up.and.down.arrow.
keys.at.the.same.time.until.the.display.shows.the.mode..Once.
the.mode.letters.are.displayed,.press.the.up.or.down.arrow.to.
change.modes..Press."START"/"STOP".to.accept.new.mode.
To. set. the. run. time,. press. either. the. up. or. down. arrow.. The.
first. digit. on. the. right. hand. side. will. flash. in. half-second. in-
tervals..Press.either.arrow.key.to.adjust.to.the.desired.value..
To. enter. the. displayed. digit. and. move. to. the. next,. press.
"START"/"STOP"..Once.the.last.digit.on.the.left.is.entered,.the.
timer.is.ready.to.start..
Press. "START"/"STOP". to. initiate. the. current. run. program..
Once.running,.pressing."START"/"STOP".again.will.pause.the.
timer. with. the. current. amount. of. time. remaining. on. screen..
When. allowed. to. time-out,. the. timer. beeps. and. displays.
"DONE"..Press.any.key.to.continue..Setting.and.Mode.values.
are.saved.automatically.and.restored.on.power-up.
Perform. your. test.. Time. required. to. complete. a. test. will. vary.
depending.upon.the.physical.characteristics.of..the.test.mate-
rial..Most.separations.will.be.complete.in.ten.minutes.or.less..
Refer.to.your.test.specifications,.and.be.consistent.
Disconnect. and. lock. out. power. to. the. Sieve. Shaker. when. it.
is.not.in.use.
NOTE: The SS-8R and SS-12R Sieve Shakers are equipped
with a tapping mechanism which makes a loud noise. If
the noise is unacceptable, consider using the SSA-805R
Sound Enclosure.
SS-8R.and.SS-12R.are.counterbalanced.to.permit.free-stand-
ing.operation.with.most.common.test.sieve.loadings..With.very.
tall.or.very.short.sieve.stacks,.the.units.may.be.unstable.and.
move. around. during. operation.. Normally. this. condition. oc-
curs.only.with.sieve..stacks.exceeding.about.20in.(508mm).in.
height..This.is.equivalent.to.using.more.than.eight.test.sieves.
and.pan.of.2.125in.stacking.height..If.you.need.to.use.tall.sieve.
stacks,.and.your.Sieve.Shaker.moves.around,.try.re-leveling.. .
If.stability.is.a.problem.with.short.sieve.stacks,.add.extra.non-
functional.test.sieves.below.an.extended.rim.pan.
Gilson Tapping Sieve Shaker Manual
NOTE: Bolting the machine down is not a substitute for
leveling. Bolting the shaker down will cause forces from
the unbalanced sieve stack to damage the drive mecha-
nism. This damage is not covered by warranty.
When. using. 8in. test. sieves. on. the. SS-12R,. always. use. the.
platform.adapter.to.compensate.for.the.difference.in.test.sieve.
weights..This.adapter.can.be.used.with.either.a.regular.or.an.
extended.rim.pan..When.the.adapter.is.positioned.with.larger.
ID. side. up,. you. can. use. either. pan.. Invert. the. adapter. for. a.
tighter. fit. if. using. only. an. extended. rim. pan.. Secure. the. ring.
to.the.test.sieve.platform.with.the.two.cap.screws.provided.
4.0 MAINTENANCE
Before.performing.maintenance.or.repairs.on.the.Sieve.Shaker,.
ALWAYS. read. and. understand. the. safety,. operating,. and.
maintenance.instructions.
Please.provide.the.serial.number.and.model.number.of.the.unit.
when.ordering.replacement.parts.
4.1 Routine Annual Maintenance
•.
Apply.of.a.few.drops.of.oil.to.the.motor.end.bearings.
•.
Inspect.the.drive.belt.for.wear,.tension,.and.alignment.
.
A. worn,. loose,. tight,. or. misaligned. drive. belt. can. affect.
operation.of.the.Sieve.Shaker..The.belt.should.be.snug:.
Neither.too.tight.nor.too.loose..A.snug.fit.assures.lon-
ger. life,. less. bearing. wear,. and. quieter. operation. than.
a. belt. which. is. too. tight.. A. loose. drive. belt. may. cause.
the. unit. to. run. too. slowly. or. in. spurts.. The. drive. belt.
should.deflect.1/64.of.the.value.of.the.span.of.the.pul-
leys.. The. pulleys. should. be. aligned. to. avoid. excessive.
edge.wear.
.
Never.force.or.pry.the.belt.over.the.pulley.flanges...Use.
steps.1–3.in.Section.4.2.
•.
Every.two.years.or.whenever.disassembled,.grease.the.
thrust.bearing.(13).and.the.face.of.the.cam.(31)..Perform.
steps.1–7.in.Section.4.2.to.access.these.parts.
4.2 Disassembly
1.. Disconnect.and.lock.out.the.power.supply.
2.. Locate. the. four. cover. mounting. screws,. and. remove.
them..Remove.right.(timer.side).section.of.the.cover.
3.. Inside.the.left.cover.section,.locate.two.more.mounting.
screws.on.the.cover.flanges..Remove.these.screws.and.
the.left.section.of.the.cover.
4.. Loosen. the. four. motor. mounting. bolts.. Motor. will. slide.
toward. the. left. side. of. the. machine,. loosening. tension.
on.the.belt.so.that.you.can.remove.it...
5.. Remove. the. four. mounting. cap. screws. (16). from. the.
mounting. plate. (17),. and. lift. the. entire. unit. out. of. its.
case...
