OPERATION
Engine Break-In
No single action on your part is as important to long, trouble-free
machine life as proper break-in of a new or rebuilt engine. Premix the
first 3.5 gallons (13.2 l) of gasoline with 16 oz. (473 ml) of the
recommended 2-cycle racing oil (28:1). Premix future gasoline at 32:1.
CAUTION
Excessive heat build-up during the first three hours of operation
will damage close-fitted engine parts. Do not operate a t full
throttle or high speeds for extended periods during the first three
hours of use. Vary the throttle openings and machine speeds to
reduce friction on all close-fitting machined parts, allowing them
to break in slowly without damage.
Use of any lubricants o ther than those recommended by Polaris
may cause serious engine damage. We recommend the use of
Polaris lubricants for your vehicle.
Drive with extra caution during the break-in period. Perform
regular checks on fluid levels, lines, and all other important areas
of the machine.
