Auxiliary Foot Brake
The auxiliary brake system is intended to be used as a backup for the
main brake system. Should the main system fail, use the auxiliary foot
brake.
Aggressively applying the auxiliary brake when backing down a hill may
cause rear tipover, which could result in serious injury or death.
Use caution when applying the auxiliary brake. Do not aggressively apply the
auxiliary brake when going forward. The rear wheels may skid and slide side-
ways, causing loss of control and serious injury or death.
The auxiliary foot brake is
located on the inside of the
right footrest. Operate this
brake with your right foot.
NOTE:
If the rear wheels slide
while using the auxiliary
brake, reduce brake
pedal pressure to brake
the rear wheels without
skidding.
Check the brake fluid level frequently for the auxiliary brake system.
See page 87.
