MAINTENANCE

PERIODIC MAINTENANCE CHART

Periodic Maintenance Overview

Inspection, adjustment and lubrication of important components are explained in the periodic maintenance chart.

Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for replacement parts, use genuine Pure Polaris parts available from your Polaris dealer.

NOTE: Service and adjustments are critical. If you’re not familiar with safe service and adjustment procedures, have a qualified dealer perform these operations.

Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle speed of approximately 10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more frequently.

Severe Use Definition

• Frequent immersion in mud, water or sand

• Racing or race-style high RPM use

• Prolonged low speed, heavy load operation

• Extended idle

• Short trip cold weather operation

Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting in the oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if it continues to rise, discontinue use and determine the cause or see your dealer.

Break-In Period

The break-in period consists of the first 25 hours of operation. Careful treatment of a new engine and drive components will result in more efficient performance and longer life for these components.

• Drive vehicle slowly at first while varying the throttle position. Do not operate at sustained idle.

• Perform regular checks on fluid levels and other areas outlined on the daily pre-ride inspection checklist.

• Change both the engine oil and filter after 25 hours or one month.

• See “Owner’s Manual” for additional break-in information.

Maintenance Chart Key

The following symbols denote potential items to be aware of during maintenance:

■ = CAUTION: Due to the nature of these adjustments, it is recommended this service be performed by an

authorized Polaris dealer.

▶ = SEVERE USE ITEM: See information provided above.

E = Emission Control System Service (California).

NOTE: Inspection may reveal the need for replacement parts. Always use genuine Polaris parts.

WARNING

Improperly performing the procedures marked ■ could result in component failure and lead to serious injury or death.

COOLING SYSTEM

Cooling System Overview

The engine coolant level is controlled, or maintained, by the recovery system. The recovery system components are the recovery bottle, radiator filler neck, radiator pressure cap and connecting hose.

As coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the radiator past the pressure cap and into the recovery bottle. As engine coolant temperature decreases the contracting (cooled) coolant is drawn back up from the tank past the pressure cap and into the radiator.

NOTE: Some coolant level drop on new machines is normal as the system is purging itself of trapped air. Observe coolant levels often during break-in period.

Overheating of engine could occur if air is not fully purged from system.

Polaris Premium 50/50 Antifreeze is premixed and ready to use. Do not dilute with water.

Coolant Strength

Test the strength of the coolant using an antifreeze hydrometer.

Coolant Level Inspection

The pressure cap under the front hood of the vehicle. The coolant level must be maintained between the minimum and maximum levels indicated on the recovery bottle.

With the engine at operating temperature, the coolant level should be between the upper and lower marks on the coolant recovery bottle. If not, perform the following procedure:

1. Position the vehicle on a level surface.

2. If the coolant level is below the MIN line, inspect the coolant level in the radiator.

NOTE: If overheating is evident, allow system to cool completely and check coolant level in the radiator and inspect for signs of trapped air in system.

Wheel Toe Adjustment

If toe alignment is incorrect, repeat steps 3-5 of “Wheel Toe Alignment Inspection”, but instead measure the distance between each wheel and the vehicle center. This will tell you which tie rod needs adjusting.

NOTE: Be sure steering wheel is straight ahead before determining which tie rod needs adjustment.

CAUTION

During tie rod adjustment, it is very important that the

following precautions be taken when tightening tie rod

If the rod end is positioned incorrectly it will not pivot,

To adjust toe alignment:

• Hold tie rod end to keep it from rotating.

• Loosen jam nuts at both end of the tie rod.

• Shorten or lengthen the tie rod until alignment is as required to achieve the proper toe setting as specified in “Wheel Toe Alignment”.

• IMPORTANT: When tightening the tie rod end jam nuts, the rod ends must be held parallel to prevent rod end damage and premature wear. Damage may not be immediately apparent if done incorrectly.

• After alignment is complete, torque jam nuts to specification.

Spring Adjustment

The front and rear shock absorber springs are adjustable by rotating the adjustment cam to change ride height.

WARNING

Uneven adjustment may cause poor handling of the

vehicle, which could result in an accident and serious

injury or death. Always adjust both the left and right

springs equally.

1. Position the vehicle on a level surface and stop the engine.

2. Raise and safely support front or rear of vehicle off the ground to allow the suspension to fully extend.

NOTE: The tires should not be touching the ground.

3. To adjust the suspension, rotate the adjustment cam

clockwise to increase spring tension or counter-

clockwise to decrease spring tension.

Spring Adjustment (FOX)

The front and rear shocks have a spring adjustment. Suspension springs may be adjusted to suit different riding conditions or vehicle payloads.

WARNING

Uneven adjustment may cause poor handling of the

vehicle, which could result in an accident and serious

injury or death. Always adjust both the left and right

Brake Fluid Inspection

Always check the brake pedal travel and inspect the brake fluid reservoir level before each operation. If the fluid level is low, add DOT 4 brake fluid only.

Brake fluid should be changed every two years. The fluid should also be changed anytime the fluid becomes contaminated, the fluid level is below the minimum level, or if the type and brand of the fluid in the reservoir is unknown.

The brake fluid master cylinder reservoir can be accessed through the left front wheel well.

1. Position the vehicle on a level surface.

2. Place the transmission in PARK.

3. View the brake fluid level in the reservoir should be between the MAX and MIN level lines.

Brake Pad / Disc Inspection

1. Check the brake pads for wear, damage, or looseness.

2. Inspect the brake pad surface for excessive wear.

3. Pads should be changed when the friction material is worn to 0.040″ (1 mm).

4. Check surface condition of the brake discs.

5. Measure the thickness of the front and rear brake discs.

6. The disc (s) should be replaced if thickness is less than 0.170″ (4.32 mm).

4. If the fluid level is lower than the MIN level line, add brake fluid until it reaches the MAX level line.

5. Install the reservoir cap and apply the brake pedal forcefully for a few seconds and check for fluid leakage around the master cylinder fittings and the brake caliper fittings.

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.

2. Refer to Chapter 2 – Engine Oil Level, page 2.14. Check oil level indicated on dipstick. Add oil if necessary.

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. Change oil and oil filter after 25 hour break-in period.
