Slack

Switch

Adjustment

(see

Fig.

5)

Tools:

Small

Flathead

Screwdriver

The

slack

switch

is

located

on

the

motor

assembly

and

is

accessible

from

the

motor

side

of

the

Climb

Max.

Remove

the

cover

(see

section

25).

Inspect

the

slack

switch

arm

to

ensure

that

it

is

not

bent.

There

are

two

screws

that

hold

the

slack

switch

in

place.

The

top

screw

slides

through

an

adjustment

slot

and

the

other

is

fixed.

Loosen

both

screws

(there

is

a

nut

on

the

other

side

that

you

can

hold

with

your

fingertip)

until

the

slack

switch

is

free

to

slide.

Turn

the

shaft

on

the

end

of

the

motor

to

tighten

the

friction

belt

on

to

the

flywheel

until

the

anchor

spring

is

fully

compressed.

Adjust

the

slack

switch

so

that

the

arm

roller

is

pressing

against

the

friction

belt

and

there

is

.01"

to

.03"

clearance

between

the

switch

body

and

the

arm.

Tighten

the

screws.

Test

the

adjustment

by

turning

on

the

power

switch

and

observing

the

friction

belt

initialization

process.

The

motor

will

tighten

the

belt

until

it

activates

the

slack

switch,

then

will

back

off

slightly.

This

process

should

be

completed

without

any

error

messages

appearing

on

the

display.

Observe

the

belt

anchor

spring.

The

spring

should

not

be

compressed

in

the

slack

state.

If

it

is

compressed,

adjust

the

slack

switch

towards

the

belt

and

test

again.

The

second

test

is

to

start

climbing.

When

you

first

step

on

the

pedal

the

belt

should

engage

smoothly.

Pedal

at

a

high

speed.

If

the

pedal

accelerates

to

a

high

rate

and

then

the

belt

grabs

abruptly,

there

is

too

much

slack

in

the

belt.

Adjust

the

slack

switch

away

from

the

belt

and

test

again.
