Adjusting the Chain

Tools required:

10

mm wrench,

two (2)

8

mm

wrenches

,

and

two (2) 1

7

mm

wrenches

.

1

U

sing two 17mm wrenches,

l

oosen the rear axle bolts by

turning the wrenches counter

clockwise.

2

Using two 8mm wrenches,

loosen the brake housing anchor

which is located in the long slot

on the left side of the rear fork.

3

Using a 10mm wrench,

tighten the tension adjusters on

the axle 1/8 to 1/4 turn to ﬁ ne-

tune the chain tension. Both

adjusters must be tightened the

exact same amount to maintain

wheel alignment.

4

Once the tension is correct,

tighten the axle and brake an-

chor bolt. Test run the scooter.

Readjust as needed.

Note:

This system of adjusters

is common to motorcycles and

BMX bicycles. If you are not

familiar with it or do not feel

comfortable performing the ad-

justment, consult an authorized

Razor service center or a quali-

ﬁ ed BMX bike or motorcycle

mechanic.

The chain should be “just taut”

– in other words snug, but not

piano-wire tight. The tension

should be similar to the fan

chain on an automobile. BE

CAREFUL NOT TO ADJUST TOO

TIGHT. The tensioning system

can easily impart too much ten-

sion and snap the chain or bend

the motor shaft. Adjust 1/8 to

1/4 turn at a time and check the

tension each time.
