Polaris 600 RMK 144, 600 RMK 144 ES Owner's Manual

The recommended maintenance schedule for a Polaris 600 RMK 144 includes regular checks every 500 miles or 50 hours of operation. This includes inspecting the drive belt, checking fluid levels, and lubricating all necessary parts.
To troubleshoot starting issues, ensure the battery is fully charged, check the spark plugs for wear or damage, and inspect the fuel system for clogs. Additionally, make sure the kill switch is in the 'run' position.
Polaris recommends using their VES (Variable Exhaust System) synthetic oil for optimal performance and protection of the engine components in the RMK 144 models.
To adjust the track tension, lift the rear of the snowmobile and use the adjusting bolts on the rear axle. The track should sag about 1 to 1.5 inches when applying 10 pounds of force at the midpoint.
Common causes of overheating include low coolant levels, a blocked radiator, or issues with the water pump. Ensure all components are clean and functioning properly to prevent overheating.
The drive belt should be inspected regularly for wear and replaced every 1,500 to 2,000 miles, depending on the riding conditions and style.
For off-season storage, clean the snowmobile thoroughly, stabilize the fuel, remove the battery, and store it in a dry, cool place. Cover the snowmobile to protect it from dust and debris.
To replace the spark plugs, remove the spark plug wire, use a spark plug socket to remove the old plug, and install a new one. Ensure the plug is torqued to the manufacturer's specification.
Power loss during acceleration can be caused by a dirty air filter, worn drive belt, or clogged fuel injectors. Inspect these components and clean or replace as necessary.
To improve fuel efficiency, ensure the engine is well-tuned, the air filter is clean, and the track is properly tensioned and aligned. Riding at a steady pace and avoiding rapid accelerations can also help.
