ENGINE BREAK-IN
The break-in period consists of the first 25 hours of
operation, or the time it takes to use 15 gallons (57 liters)
of fuel. Careful treatment of a new engine and drive
components will result in more efficient performance and
longer life for these components.
CAUTION
Use only Polaris PS-4 or PS-4 Extreme Duty Synthetic
4-Cycle Engine Oil. Never substitute or mix oil brands.
Serious engine damage and voiding of warranty can
result. Do not operate at full throttle or high speeds for
extended periods during the first three hours of use.
Excessive heat can build up and cause damage to
close fitted engine parts.
1. Fill fuel tank with unleaded fuel which has a minimum
pump octane number of 87 = (R + M)/2.

Check oil level indicated on dipstick. Add oil if
necessary.
