Your right hand controls the handlebar-mounted, spring-loaded throttle (so named because it is designed to automatically return to idling position when you remove your hand). Before each and every start, check your throttle before you turn on the ignition key. Be sure it moves freely without sticking in a partially or fully opened position, and it returns to the closed or idling position.

Remember, a frozen throttle makes your snowmobile as dangerous as a loaded gun. Never point your machine toward people or property when starting. Starting a machine with the throttle stuck open could send it hurtling out of your grasp before you could respond

Brakes. Your left hand controls a braking device to slow you down rapidly and safely. But unlike a car that depends on dry pavement for traction, a snowmobile operates on surfaces of snow and ice that have a very low amount of friction. Learn braking distances at various speeds for the many snow and ice conditions that you’ll encounter before you increase speed. Be sure to check the smooth and free operation of the spring-loaded cable control often.

Steering. Since your snowmobile is running on snow and ice and relies on friction to turn, the proper shifting of your weight and both hands on the handlebars are required to guide and turn it. Occasionally check your steering system to assure its movement is not restricted.

Headlights and taillights. Both are standard equipment and operate from a console switch when in the lights on position. When snowmobiling at night, be sure lights are clear of road dirt; slush or snow, and keep a sharp eye ahead for rough terrain, obstacles in the trail and low-hanging branches.

Night snowmobiling is delightful. Because there’s reduced visibility, check your lights before starting. (Don’t depend on that moon!) Drive slowly. Don’t overdrive headlights. Avoid river and lake crossings and don’t break new trails. Follow established ones to keep clear of cliffs or banks, barbed wire fences, guys (wires) and other obstacles. Carry a flashlight at night. Apply reflective material to your snowmobile and clothing.

Ignition system. The ignition switch controls your engine’s electrical system. Should trouble develop in your throttle control or carburetor system that prevents normal slowing down or stopping, turn your ignition key or emergency switch to the off position immediately and bring your machine to a safe stop. If your snowmobile is equipped with an electric start system, take special care to see that your throttle control cable operates freely and returns to its normal position before you switch on the ignition key. A frozen throttle and sudden ignition could pitch you off the machine, or send your driverless vehicle into bystanders or property.

Fuel system. Never check fuel level or battery with a lighted match! This is so simple a precaution that you might think it unnecessary. But on a pitchblack night a careless operator could risk severe injury for a quick look. Even a stiff breeze and an empty tank won't make this reckless practice safe. Always carry a flashlight and use a dip stick to check gasoline level. Never light a match! And remember, fumes from a battery are as explosive as gasoline when exposed to a flame! Develop the practice of looking for and eliminating any fuel leakage. Wipe up any spills.

When mixing gas and oil for a 2-cycle engine, always use a separate container to assure a perfect mixture. (See the owner's manual for proportions recommended by the manufacturer for efficient engine operation and lowest emissions.) In zero-degree weather, warm oil. Always keep away from an idling machine when mixing. Never add fuel while your snowmobile is running.

Maintenance. Appreciate the complexity of your snowmobile. Recognize the rough exposure it receives and maintain its mechanical condition. Do not operate your machine when it is faulty or if guards or components are missing.

Cruising Range. Know your cruising range. Snow and terrain conditions vary daily. Never depend on a miles per gallon or hours per gallon guess when traveling cross-country into strange territory. Always carry an adequate supply of fuel. Know your own and the machine's limits, and always carry tools and equipment.
