REPAIR AND MAINTENANCE
q Adjusting the Chain
Tools required: 10mm wrench, two (2) 8mm wrenches, and two (2) 17mm wrenches.
1
Using two 17mm wrenches,
loosen 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 fine-
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-
fied 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.
