INTRODUCTION

SAFETY

OPERATOR SAFETY

Follow the recommended maintenance program on page 39 to ensure that all critical components on the snow bike are thoroughly inspected at specific intervals outlined in the Periodic Maintenance Chart. Your dealer can perform this service.

WARNING

Driving a snow bike requires your full attention. DO NOT drink alcohol or use

drugs or medications before or while driving or riding as a passenger. They will

reduce your alertness and slow your reaction time.

Snow bikes are capable of traveling at high speeds. Use extra caution to

ensure operator safety. Make sure your snow bike is in excellent operating

condition at all times. Always check major and vital safety components before

every ride.

All Timbersled snow bikes are designed and tested to provide safe operation

when used as directed. Failure of critical machine components may result from

operation with any modifications, especially those that increase speed or

power. DO NOT MODIFY YOUR MACHINE. The snow bike may become

aerodynamically unstable at speeds higher than those for which it is designed.

Loss of control may occur at higher speeds. Modifications may also create a

safety hazard and lead to bodily injury.

HOST BIKE

The Timbersled Snow Bike system is designed to be attached to a variety of host bikes. Read and understand your host bike’s operation manual and follow all safety and maintenance information. Failure to do so could result in serious injury or death.

STAY CLEAR OF TRACK

Your snow bike is propelled by a revolving track that must be partially exposed for proper operation.

WARNING

Serious injuries may result if hands, feet, or clothing become entangled in the

track. Be alert when riding, and remain properly seated to stay clear of the

track. Never hold the snow bike up or stand behind it while warming up the

track. A loose track or flying debris could cause serious injury or death. We

recommend having your dealer perform all track service and alignment

procedures.

SAFETY

RIDING POSITION

Operating a Timbersled requires skill and balance for proper control. Rider positions may vary with experience and the features available on some models, but under many conditions the proper position is to be seated with both hands on the handlebar grips for proper throttle, brake, and steering control. See your host bike’s owners manual for proper riding position.

WARNING

Improper riding position may reduce control and could result in serious injury or

death. Always ride in a position that allows for control of your vehicle.

RIDER CAPACITY

This Timbersled is designed for a single rider only. Never carry a passenger on this vehicle.

RIDING APPAREL

HELMET

Wearing a helmet can prevent a severe head injury. Whenever riding a Timbersled vehicle, always wear a helmet that meets or exceeds established safety standards.

Approved helmets in the USA and Canada bear a U.S. Department of Transportation (DOT) label.

Approved helmets in Europe, Asia and Oceania bear the ECE 22.05 label. The ECE mark consists of a circle surrounding the letter E, followed by the distinguishing number of the country which has granted approval. The approval number and serial number will also be displayed on the label.

EYE PROTECTION

Do not depend on eyeglasses or sunglasses for eye protection. Whenever riding a Timbersled vehicle, always wear shatterproof goggles or use a shatterproof helmet face shield. Timbersled recommends wearing approved Personal Protective Equipment (PPE) bearing markings such as VESC 8, V-8, Z87.1, or CE. Make sure protective eye wear is kept clean.

CLOTHING

Be prepared, be warm and be comfortable when riding. Be aware of the weather forecast, especially the windchill, and dress accordingly. See page 22.

WARNING

Avoid wearing loose clothing or long scarves, which can become entangled in

moving parts and cause serious injury. Always wear an approved helmet and

eye protection.

SAFETY

SURVIVAL PREPARATION

For your safety, always ride in a group. Always tell someone where you're going and how long you expect to be gone. If it isn't possible to ride with others, and you must travel into remote areas, always carry survival equipment that's appropriate to the conditions you may encounter. Such equipment may include, but is not limited to: extra clothing, a sleeping bag, a flashlight, food and water, a signaling mirror, a means of building a fire, and a two-way radio or cellular telephone.

Always carry the owner’s manual on your snow bike. For added protection, purchase and carry the following items on your snow bike as well:

• Extra Set of Spark Plugs

• Tow Rope

• Extra Oil

• Fuel Deicer

• Winter Survival Kit

• Spare Drive Chain

• Spare Chain Case Chain (if equipped)

• Trail Map

• First Aid Kit

• Tool Kit

EXCESSIVE SPEED

WARNING

High speed driving, especially at night, could result in serious injury or death.

Always reduce speed when driving at night or in inclement weather.

Always observe all state and local laws governing snow bike operation and speed limits. Always be alert and pay attention to the trail ahead. If your speed is 40 MPH (64 km/h), your snow bike is traveling about 60 feet (18 m) per second. If you look back for only two seconds, your snow bike will travel about 120 feet (36 m). If your speed is 60 MPH (96 km/h), your snow bike will travel about 180 feet (55 m) in two seconds.

Traveling at night requires extra caution. If your host bike is equipped with a headlight, check headlight and taillight to ensure proper operation, and don’t over-drive your headlight beam. Always be able to bring your snow bike to a stop in the distance illuminated by the headlight.

SAFETY

DRIVER AWARENESS

Slow down when traveling near poles, posts, or other obstacles. Be especially alert if you're snow biking after dark. Always be on the alert for wire fences. Single strands are especially dangerous, since there may be a great distance between posts. Guy wires on utility poles are also difficult to distinguish.

Make sure the way is clear before crossing railroads and other roads and highways. The noise of your snow bike will drown out the sound of approaching vehicles. Look ahead, behind, and to both sides before turning or crossing railroad tracks or highways. Steep embankments may also hide your view. Always leave yourself a way out.

Variances in snow depth and/or water currents may result in uneven ice thickness. You may drown if you break through the ice. Never travel on frozen bodies of water unless you have first verified that the ice is sufficiently thick to support the weight and moving force of the snow bike, you and your cargo, together with any other vehicles in your party. Always check with local authorities and residents to confirm ice conditions and thickness over your entire route. Operators assume all risk associated with ice conditions on frozen bodies of water.

When teaching inexperienced operators to ride, set up a predetermined course for practice. Make sure they know how to drive and control the snow bike before allowing them to make longer trips. Teach them proper snow bike courtesy, and enroll them in driver's training and safety courses.

DISABLED OPERATORS

Safe operation of this rider-active vehicle requires good judgement and physical skills. Operators with cognitive or physical disabilities have an increased risk of loss of control, which could result in serious injury or death.

SAFETY

MOUNTAINOUS TERRAIN RIDING

Mountainous terrain operation, even for experienced riders, can present conditions and situations that could result in serious injury or death. Please review all of the information about riding in mountainous terrain on the following pages of this manual.

WARNING

An avalanche can occur at any time, in any conditions and on any slope.

The avalanche information provided in this manual should be considered basic information and is not intended to replace your participation in an avalanche safety training course. After reviewing the avalanche information in this manual, be sure to participate in an avalanche safety training course before riding in mountainous terrain. The training course will provide more information as well as the opportunity to practice riding and using proper search and recovery techniques.

For more information, education, training courses, and links to international resources, visit www.avalanche.org or scan the QR code with your smartphone or other device.

GET THE SAFETY GEAR

In addition to carrying a spare belt, spark plugs and tools on each snow bike, each person in your riding group should wear the recommended snow bike riding apparel and carry (on their person) the following survival items when riding in mountainous terrain:

• A digital avalanche beacon with new “fresh” alkaline batteries

• An avalanche probe

• A compact shovel and hand saw

• A backpack (preferably an avalanche air bag backpack)

• Emergency provisions, including the following items: – Small first aid kit

– Extra pair of gloves – Extra dry socks – Tow rope, map, compass/GPS – Lighter or waterproof matches – Signal mirror and whistle – Bottled water – High calorie snack food – Compact emergency blanket – Cell phone – Radio

SAFETY

GET TO KNOW YOUR SAFETY GEAR

Following the safety gear and apparel recommendations will increase your chances of survival if you encounter an avalanche or become stranded in the backcountry, but even experienced and properly-equipped snow bikers, hikers and skiers perish in avalanches or succumb to hypothermia. Using a beacon or probe for the first time during an avalanche recovery operation, or not knowing how to deploy your avalanche air bag backpack during a slide, should be considered UNACCEPTABLE to you and all members of your riding group. It’s critical that you and all members of your riding group know how to use the safety gear.

While you may know how to use your gear, you may have to rely on your riding group to find you in an avalanche. Make sure they know how to use their gear.

• Dress in layers. Multiple layers of clothing provide the best barrier to cold and wind. Layers can be removed, but if you start out without enough layers, they cannot be added later. Avoid cotton materials, which will freeze if they get wet.

• Wear highly visible gear.

• Try on all gear and equipment to make sure it fits and doesn’t interfere with your riding capabilities. Place all survival aids in your backpack and wear the backpack at all times. Non-essential items can be stored on the snow bike in an accessory bag.

• Read and follow the manufacturer’s user and maintenance instructions for all gear. If you have questions about how your gear works, contact the manufacturer for more information.

• Practice using your beacons, shovels and probes with your riding group in real-world conditions wearing all of your gear. Have someone hide an active “transmitting” beacon by throwing it (not walking it) into a snowbank and timing your group’s search for it.

• Test deploying your gear. If you own an avalanche air bag backpack, check with the manufacturer’s test deployment guidelines and bottle weight replacement specifications. Most air bag backpack manufacturers recommend testing the pack once a year so you know it works and feel comfortable with the bag and deployment time.

• Make sure your probe and shovel are in good condition and that you know how to assemble them.

SAFETY

GET THE PICTURE

Slopes steeper than 30º are more prone to avalanches, but any slope should be considered avalanche terrain, even small slopes with trees. Low-angle slopes are also avalanche terrain if they have steeper slopes above them.

NOTE

The 30º slope graphic is for illustration purposes only. The risk of an avalanche

is always present in mountainous terrain, regardless of slope angle.

Always look for the following warning signs of unstable snow. If you see or hear any of these signs, riding on or below any slope is dangerous and should be avoided:

• Recent avalanches

• A “whumpfing” sound under a snowpack

• Cracks across the top of a snowpack

• A recent heavy snowfall

• Blowing snow

• Rain

• Rapid warming

GET OUT OF HARM’S WAY

• Before riding, always tell a responsible person (i.e. at the lodge or gas station) where your group is going.

• Never ride alone. Always ride in a small, manageable group. Riding in a large group makes it more difficult to track riders or find missing members.

• Go “one at a time”. Only one snow bike at a time should cross, ascend or highmark a slope. Other riders should watch from a safe location until the previous rider exits the slope.

• Never park at the base of a slope or at the bottom of a gully or valley. When parking to take a break or watch other riders, park at the sides of the slope with the front of your snow bike pointed away from the slope.

SAFETY

GET TO KNOW YOUR MOUNTAIN SNOW BIKE

The following information pertains to a deep snow/mountain snow bike. This type of snow bike is longer and narrower and has a higher center of gravity when compared to a typical trail snow bike. These features make riding the backcountry a safer and more enjoyable experience.

The mountain snow bike is slower, has a larger turning radius and will overturn more easily than a trail snow bike. The skis are designed to float and provide more lift than trail skis. The track features paddles that pack and shovel snow rather than dig in and grip the snowpack.

Because Timbersled mountain snow bikes feature tall track paddles, the rear suspension rails and sliders will sit above the snowpack on a groomed trail.

Always deploy the scratchers and limit high speed operation when trail riding.

Always practice riding your mountain snow bike in a safe, open, flat area before attempting your first ride in mountainous terrain. This is especially important for low-elevation riders who are not accustomed to riding a snow bike designed for deep snow.

Do not ride in mountainous terrain until you are comfortable riding and controlling your snow bike in deep snow.

• Practice turning, leaning and braking, both on the trail and off the trail. When you’re comfortable with these maneuvers, practice more advanced maneuvers in deep flat snow.

• Learn techniques from more experienced riders.

• Practice placing your feet in different locations on the floorboards to learn where your balance point is while performing turns and other maneuvers.

• Practice traversing through deep snow, which is when you will often need to steer by leaning your body weight in the desired direction while turning the skis slightly in the opposite direction.

• Practice using proper throttle control to maintain vehicle momentum and adequate track speed in deep snow. Everyone gets stuck at some point in time. If you know your snow bike is becoming stuck, try to turn downhill as much as you can before the snow bike comes to a stop.

GET THE FORECAST

Make a riding plan based on the current avalanche and weather forecast. It is important to remember that overnight weather conditions may have created unsafe riding terrain that was considered safe the day before. Visit www.avalanche.org or scan the QR code. Follow the page links to locate current avalanche reports and conditions for your area of operation.

SAFETY

GET AVALANCHE SAFETY TRAINING

Timbersled recommends you and all members of your riding group participate in an avalanche safety course. Visit www.avalanche.org/education or scan the QR code for education and training resources.

AVALANCHE AWARENESS

Avalanches are a matter of timing. A steep slope can be safe one day, but unsafe the next day due to changing weather and wind conditions.

• Always review the user instructions provided with your safety equipment and follow the recommendations for maintenance, testing and use. Always test your safety equipment to ensure it works properly before riding in mountainous terrain.

• Always store your survival gear in your backpack and wear the backpack. Do not store your survival gear on the snowmobile.

• Always research current avalanche conditions in your area of operation before riding. Check with local law enforcement, resort or lodging personnel, gas station attendants and other riders to learn about current conditions and any advisories in the area.

• Read and understand the avalanche danger scale. Pay attention to any danger level warnings issued for your area of operation.

• Always remain alert while riding in mountainous terrain. Be aware of snowpack conditions above you as you ride. Avalanches can occur at any time regardless of current condition reports.

SAFETY

ICE AND SNOW BUILD-UP

WARNING

Ice and snow build-up may interfere with the steering and braking of your snow

bike, resulting in serious injury or death. Keep the snow bike free of snow and

ice.

Before driving, manually turn the ski to the left and right to be sure ice and snow are not interfering with full left and right steering. If difficulty is encountered, remove ice and snow build-up that may be obstructing the steering.

DRIVING ON SLIPPERY SURFACES

WARNING

Never attempt an abrupt change of direction when operating on slippery

surfaces. Proceed slowly and use extra caution. Driving on ice or hard-packed

snow reduces steering and braking control, which may result in loss of control

and serious injury or death. Slow down and use extra caution when operating

on slippery surfaces.

INADEQUATE SNOW CONDITIONS

NOTICE

Driving in too little snow will result in excessive wear and damage to the slide

rail, track, ski, ski skags, and/or spindle.

WARNING

Inadequate cooling and lubrication will lead to overheating of the slide rail and

track, causing premature wear, damage and failure, which can result in serious

injury. Reduce speeds and frequently drive into fresh snow to allow adequate

cooling and polishing of the slide rail and track surfaces. Avoid operating for

prolonged periods on ice, hard-packed surfaces or roads.
