  • Page 12 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.
  • Page 13 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.
  • Page 14 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.
  • Page 15 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.
  • Page 16 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.

  • Page 18 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.
  • Page 19 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.

  • Page 21 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.
  • Page 22 SAFETY OPERATING IN DEEP SNOW If the snow bike becomes stuck in snow, clear the track and tunnel area of snow, then step down the snow in front of the snow bike so that when the throttle is opened, the snow bike will be able to climb up and over the snow. DRIVING DOWNHILL When riding downhill, shift your weight to the rear of the snow bike and reduce your speed to a minimum.
  • Page 23 SAFETY COLD WEATHER DRIVE-AWAY Whenever your snow bike has been parked for a length of time, especially overnight, always make sure the ski and track are loosened from ice and snow before attempting to drive. Apply the throttle with enough authority to put the snow bike into motion, but always operate within safety limits.

Ride your snow bike. 2. Adjust the rear track shock spring to tune vehicle balance (ski pressure and weight transfer).
  • Page 30 THE PERFECT FIT RYDE FX COIL OVER SHOCKS All RAW models are equipped with Ryde FX coil over shocks specifically designed for snow bike application. The Ryde FX shocks have no spring pre- load, compression, or rebound adjustment. They come from the factory pre-set with the best recommended settings.
  • Page 31 THE PERFECT FIT REAR TRACK SHOCK SPRING SETTINGS Always perform shock spring preload adjustments with the weight of the vehicle removed from the shock and with the shock at full extension. If adjustments to the factory-installed springs are not sufficient for riders over 300 lbs.
  • Page 32 THE PERFECT FIT 3. Thread the pump onto the valve-stem until the pump pressures up and you will be able to see the supplied pressure on the gauge. NOTE When the pump pressures up the shock instantly loses 20 psi from the volume it takes to fill the pump hose.

  • Page 46 MAINTENANCE BRAKE COMPONENTS Brake Caliper Brake Disc Brake Pad Material Brake Line EXCESSIVE LEVER TRAVEL Hydraulic brakes are self-adjusting, but if excessive brake pad clearance develops, bring the snow bike to an authorized Timbersled dealer for inspection and adjustment. The lightweight brake discs have vent holes that may cause a high-pitched sound during operation.
  • Page 47 MAINTENANCE BRAKE FLUID The brake fluid level can be seen through a plastic sight glass in the brake reservoir. If the fluid is sufficient, the sight glass will be black. If the sight glass is any color other than black, add brake fluid. Replace brake fluid at least every two years with DOT 4 high temperature brake fluid, or an equivalent product.
  • Page 48 MAINTENANCE BLEEDING THE HYDRAULIC BRAKE SYSTEM Air in the hydraulic brake system will cause spongy brake lever action. If the brakes feel spongy, bleed the system before operating the snow bike. WARNING Operating the vehicle with a spongy brake lever can result in loss of brakes, which could cause an accident and lead to serious injury or death.
  • Page 49 MAINTENANCE DRIVE SYSTEM DRIVE CHAIN TENSION TFS (TIMBERSLED FIXED STRUT) MODELS Check drive chain tension before riding. Place a ruler on the top of the chain tensioner pivot point. Measure a total of ½” to 5/8” up and down free play on the top side of the chain.
  • Page 50 MAINTENANCE TRACK INSPECTION 1. Using a hoist, safely lift and support the rear of the snow bike off the ground. 2. Rotate the track by hand to check for damage. 3. Carefully examine the track along the entire length of each rod. Bend the track to check for breakage.
  • Page 51 MAINTENANCE SKI SKAGS WARNING Worn skis and/or skags will adversely affect handling. Loss of vehicle control may result, causing serious injury or death. See your dealer's studding chart for recommended skags. Check skags before each use of the snow bike to ensure positive steering characteristics.
  • Page 52 MAINTENANCE SPINDLE MAINTENANCE The spindle does not require any maintenance. It is designed to bend if it comes in contact with a rock or stump during operation. Timbersled recommends thoroughly inspecting the assembly for bends or cracks before you ride. FALL TUNE-UP For maximum performance, your Timbersled dealer can perform a fall service tune-up.
  • Page 53 MAINTENANCE EXTENDED STORAGE Off-season or extended storage of your snow bike requires preventive measures to aid against deterioration and to prolong the useful life of many components.
