Engine Break-In Period

The break-in period consists of the first 25 hours of
operation, or the time it takes to use 14 gallons (53 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 PLUS or Extreme Duty
Synthetic 4-Cycle engine oil or an equivalent.
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.
2. Check oil level indicated on dipstick. Add oil if
necessary (Refer to Chapter 2, "Engine Oil Level").
3. Drive slowly at first to gradually bring engine up to
operating temperature.
4. Vary throttle positions. Do not operate at sustained
idle or sustained high speed.
5. Perform regular checks on fluid levels, controls and all
important bolt torques.
6. Pull only light loads during initial break-in.
7. Change oil and oil filter after 25 hour break-in period.
