General Maintenance
Jump-Starting
NOTE: ARGO does not recommend jump-starting a vehicle with a dead battery
but rather to remove the battery, service it, and correctly charge it.
Improper handling or connecting of a battery may result in severe injury including
acid burns, electrical burns, or blindness as a result of an
explosion. Always remove rings and watches.
WARNING
Any time service is performed on a battery, the following must be
observed: keep sparks, open ame, cigarettes, or any other ame away. Always wear
safety glasses. Protect skin and clothing when handling a battery. When servicing
battery in enclosed space, keep the area well-
ventilated. Make sure battery venting is not obstructed.
WARNING
Spark Plug
Your ATV is equipped with a specic spark plug (see “Specications” for the
correct spark plug). The appearance of the insulator on a used spark plug will help
determine if it is the proper one for your ATV.
A light brown insulator indicates that the spark plug is correct. A white or dark
insulator indicates that the engine may need to be serviced or adjustments made.
Consult an authorized ARGO dealer if the plug insulator is not a light brown color.
To help prevent cold weather fouling (a buildup of carbon and unburned fuel on the
spark plug) make sure you thoroughly warm up your ATVs engine before riding.
Before inspecting a spark plug, clean the area around the spark plug to prevent any
dirt from entering the engine when remove or installing the spark plug.
A. Spark plug gap
Adjust the spark plug’s ground electrode
gap to 0.024 - 0.028 in. (0.6 - 0.7 mm).
Use a wire-type feeler gauge to check the
gap.
When installing a spark plug, be sure to tighten it securely. A new spark plug should
be tightened 1/2 turn once the washer makes contact with the cylinder head. A used
spark plug should be tightened 1/8 - 1/4 turn once the washer makes contact with
the cylinder head.
