OPERATION WARNINGS
Hydraulic Brakes
The need for a properly functioning brake is vital. Polaris snowmobiles are
equipped with the highest quality hydraulic disc brake system available. The fol-
lowing items must be checked each time before starting the engine to assure prop-
er operation.
Brake Lever Travel
When the brake handle is de-
pressed (A) , it should move no
closer than 1/2
″
(1.3 cm) from the
handgrip. Excessive travel indi-
cates low fluid level or air in the hy-
draulic system. If the lever travel
is excessive, refer to the brake
bleeding information on page 69.
Lever Feel
A hydraulic system multiplies the force of your hand squeeze on the brake lever.
Proper operation depends upon an adequate air and moisture-free supply of hy-
draulic brake fluid in the system. If the brake lever feels “spongy” when squeezed,
the level and condition of the fluid must be checked; as well as checking for the
presence of air in the fluid system. Refer to page 69 for more information or contact
your dealer for service. Replace brake fluid at least every two years with Polaris
DOT 3 high temperature brake fluid. All DOT 3 brake fluid is not alike. We recom-
mend the use of Polaris brake fluid (PN 2870990).
WARNING
Continued abusive brake application with a “spongy” brake condition may cause
a complete loss of brakes; which could result in severe injury or death.
Mechanical Brakes
Brake Lever Travel
Measure the clearance between the
lever and brake block. Inspection
should be made with the lever firmly
depressed. Distance B should be no
more than 3/4
″
(1.9 cm).
Excessive travel indicates a need to
adjust the brake cable adjuster. Re-
fer to the mechanical brake adjust-
ment information on page 72.
