WARNING
• After adjusting the brake lever position,
make sure the pin on the brake lever holder
is firmly inserted in the hole in the adjusting
dial.
• A soft or spongy feeling in the brake lever
can indicate the presence of air in the brake
system. Before the vehicle is operated, the
air must be removed by bleeding the brake
system. Air in the brake system will consid-
erably reduce brake performance resulting
in loss of control and possibly cause an ac-
cident. Therefore, check and if necessary,
bleed the brake system.
