ALWAYS
. read. and. understand. the. safety,. operating,. and.
maintenance.instructions.
Always
.disconnect.the.SS-15.from.its.power.before.perform-
ing. maintenance. or. repair.. The. SS-15’s. motor. has. internal.
thermal.protection.which.may.cause.it.to.restart.automatically.
3.1 Cleaning the Unit
1.. Clean. the. unit.
AT LEAST
. once. a. year.. It. is. designed. to.
give.consistent.results..Dirt.can.affect.test.results..An.ap-
propriate.cleaning.schedule.for.your.unit.depends.on.the.
frequency.of.use,.exposure.to.dirt,.and.sample.makeup.
2.. Clean. beneath. the. unit. at. least. annually.. Take. care. not.
to.introduce.cleaning.agents.into.the.timer.or.the.motor..
If. a. thorough. cleaning. is. required,. the. motor. and. timer.
must.first.be.removed..See.steps.2.and.3.in.Section.3.3.
3.. To. perform. maintenance. or. repairs,. or. to. inspect. the.
internal.parts.of.the.SS-15,.place.the.unit.on.either.of.its.
sides.or.on.its.back.as.appropriate..Make.sure.to.prop.
up. the. machine. as. necessary. to. avoid. damage. to. the.
power.cord.or.platform.
3.2 Drive Belt
1.. Periodically.check.drive.belt.for.wear,.tension,.and.align-
ment..A.worn,.loose,.tight,.or.misaligned.drive.belt.can.
affect. the. operation. of. your. SS-15.. The. belt. should. be.
snug:..neither.too.tight.nor.too.loose..A.snug.fit.assures.
longer.life,.less.bearing.wear,.and.quieter.operation.than.
a. belt. which. is. too. tight.. A. loose. belt. may. cause. the.
unit. to. run. too. slowly. or. to. slip.. The. drive. belt. should.
deflect. 1/64. of. the. value. of. the. space. of. the. pulleys..
The.pulleys.should.be.aligned.to.avoid.excessive.edge.
wear.on.the.belt.
2.. To.adjust.or.replace.the.belt,.lay.the.unit.on.its.left.side,.
making. sure. not. to. pinch. the. electrical. cord.. . Loosen.
the. four. Motor. Mounting. Bolts. (26). on. the. top. of. the.
outer. case. (see. Section. 7.0).. Move. the. motor. up. or.
down.to.adjust.tension.in.the.drive.belt..Use.a.straight-
edge. to. maintain. pulley. alignment.. If. you. must. adjust.
the. belt. past. the. end. of. the. slots. to. get. proper. snug-
ness,.replace.the.belt.
NEVER
.force.or.pry.the.belt.over.
the.pulley.flanges.
3.3 Motor

3.. Disconnect. the. power. and. timer. wire. terminals,. noting.
where. each. is. attached,. loosen. the. cord,. and. remove.
the.wires.from.the.motor.terminal.box..The.motor.is.now.
completely.free..Remove.motor.belt.pulley.by.loosening.
the.setscrew.
4.. Have. the. motor. cleaned. or. overhauled. by. a. trained.
electric. motor. repair. person.. Replacement. motors. are.
available. from. Gilson.. To. install. the. motor,. reverse. the.
