Snowmobile Polaris 650 Pro RMK 155 / 650 RMK Khaos 146 Slash / 850 Pro RMK 155. Owner’s Manual (2024)

Check skags before each use of the snowmobile to ensure positive steering
characteristics. Skags must be replaced when worn to half their original
diameter. Replace if carbide is damaged or worn away.

TIP

Carbide skags must be replaced if any abnormal wear or chipping is found.

SKAG REPLACEMENT

WARNING

Worn skis and/or skags will adversely affect handling. Loss of vehicle control

may result, causing serious injury or death. See your authorized POLARIS

dealer's studding chart for recommended skags. If you install longer or more

aggressive carbide skags than the original equipment, it may also be

necessary to add track studs to maintain proper vehicle control while turning

on hard-packed snow or ice.

NOTICE

Always replace ski skags in pairs.

To replace ski skags, do the following:

1. Raise and support the front of the

snowmobile so the skis are
approximately 6 inches (15.2 cm)
from the ground.

2. Remove the attaching nuts

and

pry the skag downward.

3. Reverse the steps to install a skag.

Tighten nuts to specification.

RAIL SLIDE WEAR INSPECTION

Polaris rail slides

run along the bottom of the rail to prevent track wear. The

rail slide should be inspected periodically and replaced when necessary.

For ease of inspection, all POLARIS rail slides have a wear limit indicator groove

to indicate the minimum permissible slide thickness

. Replace the rail slides

if they are worn to the top of the groove at any point along their length. Failure to
do so may result in permanent damage to the track or rails.

BATTERY CHARGE RELAY CONTROL

Some models are equipped with a battery. The battery provides power for only
two purposes:

• Engaging the electric starter motor to start the engine
• Powering the 7S Display with the ignition key when the engine is off

The engine management system turns on the battery charge relay and charges
the battery only when the following conditions are met:

• The load shed relay is turned on by the engine management system
• Engine speed exceeds 2500 RPM
• Chassis DC voltage exceeds 13 volts

BATTERY MAINTENANCE

Keep battery terminals and connections free of corrosion. If cleaning is
necessary, remove the corrosion with a stiff wire brush and wash with a solution
of one tablespoon baking soda and one cup water. Rinse well with tap water and
dry off with clean shop towels. Coat the terminals with dielectric grease or
petroleum jelly to prevent corrosion.

Never store a battery in a partially charged condition or hard, crystal sulfation will
form on the plates resulting in reduced efficiency and shorter service life of the
battery.

If you do not drive the vehicle for more than TWO weeks, maintain Absorbent
Glass Mat (AGM) batteries with the BatteryMINDer® 2012 AGM - 2 AMP
charger (or a similar charger).

SUMMER/LONG-TERM STORAGE GUIDE

TREATING THE FUEL SYSTEM

As the riding season draws to a close, Polaris recommends riders begin treating
their snowmobile’s fuel system with Polaris Carbon Clean or similar
commercially-available fuel stabilizer.

Treating the fuel system with Carbon Clean during the last few rides of the
season ensures the entire fuel system is treated. Then, when it comes time to
store the snowmobile, all the rider has to do is completely fill the fuel tank with
fresh, non-oxygenated fuel and treat the new fuel with Carbon Clean.
It is also recommended riders use non-oxygenated fuel during the last rides of
the season as non-oxygenated fuel stores better than oxygenated fuel and
resists water vapor absorption.
If the rider was unable to treat the fuel system and/or use non-oxygenated fuel at
the end of the riding season, the rider should do the following:

1. The rider should consume as much fuel in the fuel tank as possible during

the last rides of the season.

2. When performing the summerization storage procedures, fill the fuel tank

completely with non-oxygenated fuel. Note that most oxygenated fuels
contain ethanol. Since ethanol is hydroscopic, oxygenated fuel will absorb a
small amount of water vapor during the storage season and more so in
humid locations. Completely filling the tank with non-oxygenated fuel
minimizes water vapor absorption during the storage period and limits the
amount of air and water vapor that can accumulate in the tank.

3. Treat the fuel in the fuel tank with the recommend amount of Polaris Carbon

Clean. The recommended mixing ratio is outlined on the bottle label.

4. Position the snowmobile outside in a well-ventilated area.

5. Start and run the engine for 10-15 minutes to distribute the treated fuel

throughout the fuel system.

NOTICE

On Carbureted engines (550cc / 120 Youth), run the engine for 10-15 minutes

and then turn the fuel shut off valve to ‘OFF’. Continue to run the engine until

the engine stalls and turns off. Doing this drains the carburetors of fuel.

173

MAINTENANCE

FOGGING THE ENGINE

Fogging the engine with Polaris fogging oil or similar commercial alternative is
probably the most important storage step a rider can do to ensure the internal
parts of their snowmobile’s engine do not rust and corrode during the storage
season.

To fog the engine, do the following:

1. Remove the spark plugs from the engine.

2. Liberally spray fogging oil into each spark plug hole. If possible, have an

assistant slowly pull on the recoil rope to rotate the engine while spraying the
oil into each cylinder.

3. Loosely install the spark plugs.

NOTICE

Do not install new spark plugs after fogging the cylinders. Fogging oil prevents

the formation of rust / corrosion by sticking to the internal engine components –

including the spark plug electrodes. Replace these spark plugs the following

season after all of the fogging oil has been burned out of the engine.

DRIVE BELT STORAGE

Never leave the drive belt installed in the clutches as oxidation may form where
the belt contacts the aluminum clutch sheave faces.

To clean the drive and driven clutches, do the following:

1. Remove the primary and spare drive belt from the snowmobile.

2. Inspect the drive belt for wear and glazing. Compare the primary belt with the

spare belt. Decide if a new belt is needed next season and note the primary
belt can now be used as the spare belt next season.

3. Clean the drive and driven clutch sheaves with Isopropyl Alcohol. Allow the

alcohol to air dry. Continue cleaning the sheave faces until all belt residue is
removed.

174

MAINTENANCE

BATTERY/ELECTRICAL SYSTEM STORAGE

Never leave a battery
unattended during the storage
season. Snowmobile batteries
are small and cannot maintain
their charge over the storage
season. To ensure your battery
maintains its level of charge, the
battery should be connected to a
battery trickle charger using the
battery charge port.

1. While the battery can remain installed on the snowmobile, it is recommended

the battery be removed from the snowmobile and stored in a cool, and dry
location. Removing the battery from the snowmobile facilitates off-site
storage of the snowmobile where electricity may not be available to connect
a battery charger. In addition, removing the battery allows access to other
maintenance items, such as the chaincase chain tensioner bolt.

2. Connect a Polaris battery charger or equivalent commercially available

charger to the battery.

3. Inspect the electrical connections and wire harnesses throughout the

snowmobile. If damage is found, make a note of the damage so that you and
your authorized Polaris dealer can address the concern.

CLEANING THE SNOWMOBILE

Snowmobiles, especially those transported on sled decks and open trailers can
accumulate a lot of water and road dirt / salt during the riding season. The
snowmobile must be thoroughly washed and cleaned to prevent corrosion and
rust formation.

Cleaning any Polaris snowmobile should ONLY be done with a mild soap and
water solution. Any cleaning, buffing or waxing products containing colorant dye
should be avoided. If using products with colorant dye in them, test on an
inconspicuous area of the bodywork before applying, as a dye may stain the
finish.

The deep gloss surfaces of Matryx snowmobiles are achieved through a
combination of Painted and Molded Nylon 6 material. Molded Nylon 6 delivers
improved strength and durability while providing a lustrous surface finish. With
proper care they will provide years of durable service.

175

MAINTENANCE

1. Wash the snowmobile with mild soap and water. Note that if a pressure

washer is used, care should be taken to not point the pressure washer
nozzle close to the snowmobile, which may force high pressure water into
suspension / shock shaft seals and exposed electrical connectors.

2. Dry the snowmobile with a lint-free towel. Allow the entire snowmobile to air

dry afterwards.

3. Clean the engine compartment. Use a shop vacuum if required to remove

dirt, leaves, cat tails, etc. from within the engine compartment.

4. If choosing to apply a cleaner, wax or polish, make sure it does not contain a

colorant dye and/or test on an inconspicuous area of the panel. Also make
sure the product is safe to use on Molded Nylon 6 material with or without a
painted finish.

5. Hand wash the exhaust system and dry the pipe and silencer with a clean

shop towel.

6. Apply “spray” metal protectant on exposed metal components, such as the

exhaust pipe, silencer, shock shafts, and suspension springs / pivots.

IMPORTANT

Do not spray metal protectant on the drive or driven clutches.

MOLDED NYLON 6 BODY PANELS

IMPORTANT

The use of a high speed/orbital polisher/buffer is not recommended on Molded

Nylon 6 components and could result in color fading.

LUBRICATE THE PIVOTS

After washing the snowmobile, it is important to use Polaris Premium All Season
grease to lubricate the various suspension / steering pivot points. Doing so
forces any water accumulated within the joints out which prevents the formation
of corrosion and rust.

1. Use a grease gun and Polaris Premium All Season Grease. Reference the

appropriate Owner’s Manual to locate any / all grease zerks on the steering
and suspension systems.

2. Pump fresh grease into all zerks until the grease can be seen purging out of

each joint.

3. Use a paper towel to clean up and remove all of the residual purged grease

from the joints.

177

MAINTENANCE

STORING THE SNOWMOBILE

Never store the snowmobile in a hot, humid location if possible. Try to store the
snowmobile away from direct sunlight.

1. Cover the snowmobile with a Polaris cover or after-market equivalent cover.

2. Store in a location away from water, tall grass, and direct sunlight. The

storage location should have some level of ventilation to prevent stagnant,
humid air from accumulating in and around the snowmobile.

WINTER RIDE PREPARATION

Preparing a snowmobile for in-season service is basically performing some of
the summer storage procedures in reverse order.

1. Move the snowmobile outside to a well-ventilated area. Raise the rear

suspension up, off the ground. Remove the engine compartment side panel
and hood.

2. Prep the primary and back up (secondary) belts for winter use. It is

recommended the belts be washed with a solution of warm, soapy water and
allowed to air dry.

3. If the snowmobile is equipped with electric start or a lightweight battery for

the 7S display, remove the battery from the battery charger and re-install it
back into the battery box. Follow the owner’s manual for battery installation
procedures.

4. Verify the spark plugs are installed and torqued. Re-install the spark plug

wires.

NOTICE

Verify you hear an audible “click” when pushing the spark plug caps down onto

the spark plugs. This ensures the plug caps are seated properly.

5. If you placed dryer sheets inside the engine compartment, remove them.

6. Using clean and dry shop towel, wipe down the exhaust pipe , silencer, and

clutch sheaves.

7. Install the primary drive belt onto the clutches with the “Polaris” writing

readable from the outside of the snowmobile.

8. Install the back-up (secondary) drive belt into the belt holder.

9. On carbureted snowmobiles, turn the fuel shut-off valve to the ON position.

10. With the track suspended up, off the ground, follow the track tension

adjustment procedure as outlined in your owner’s manual.

178

MAINTENANCE

11. Start and run the engine. Allow the engine to run for at least 15 minutes.

Occasionally “blip” the throttle to rev the engine.

NOTICE

The exhaust may emit more smoke than usual as the fogging oil is burned out

of the engine.

12. While the engine is running, verify there are no coolant leaks (on liquid

cooled engines). After engaging the throttle a few times to spin the track,
verify the track is aligned with the slide rails.

13. Turn off the engine. If the track requires, re-align the track at this time.

14. After adjusting the track or allowing the engine to cool down. Add coolant to

reservoir bottle if required.

15. Re-start the engine and allow it to run for another 15 minutes. After 15

minutes, shutoff the engine and allow the exhaust pipe to cool.

16. Remove and discard the spark plugs. Install new spark plugs into the engine.

Obtain two more new spark plugs and install them into the spark plug holders
or storage bag.

17. Inspect the ski wear bars/carbides. Now is the time to replace the wear bars

if damage if found or carbides are worn.

18. Add Carbon Clean to the fuel tank.

19. If equipped with a 7S Display, log onto www.ridecommand.com and

download the software.

20. Grease the rear suspension grease zerks with Polaris Premium All Season

grease just enough to push out any water that may have accumulated in the
suspension pivot points.
