WARNING: The brake

throwing an unsuspecting rider.
Practice in an open area free from
obstacles until you are familiar with
the brake function. Avoid skidding
to a stop as this can cause you to
lose control or damage the rear tire.
Note: The brake lever contains a
safety switch to cut power to the
motor when the brake is applied. In
an emergency, applying the brake
will always stop the product from
moving. Do not disable or replace
this lever with anything other than
a genuine Razor replacement part.
1 To adjust the play, thread the
brake lever adjuster on the hand
brake in or out 1/4 to 1/2 turn until
the desired brake adjustment is
attained. Most adjustments are
complete at this step. If brake still
needs further adjustment, proceed
to step 2.
2 If brake is too tight or has too
much slack, use a 10mm wrench
to loosen the nut for additional
adjustment on the brake cable on
the rear wheel. Securely tighten
nut when done.
Testing the Brakes
To use the brake, squeeze the lever to increase the pressure on the brake. The brake lever is fitted with a cable adjuster
to compensate for cable stretch and/or to fine-tune the lever movement to brake engagement. If brake is not engaging
properly, follow instructions for adjusting the brakes.
