  • Page 16: Survival Preparation

    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 21 SAFETY Always practice riding your 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.
  • Page 22 SAFETY • 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.

  • Page 24: Ice And Snow Build-Up

    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 25: Driving Downhill

    SAFETY DRIVING DOWNHILL When riding downhill, shift your weight to the rear of the snow bike and reduce your speed to a minimum. Apply just enough throttle to keep the engine from stalling, allowing the engine's compression to help slow the snow bike and keep it from rolling freely downhill.

  • Page 26: Driving Responsibly

    SAFETY MANEUVERABILITY While much control and maneuverability is achieved through the steering system and ski, maximum control is achieved by the shifting of your body weight. Maneuverability will change for lighter operators. DRIVING RESPONSIBLY Every snow bike handles differently, and even the most benign conditions may become dangerous if operators drive improperly.

  • Page 65: Hydraulic Brake Inspection

    MAINTENANCE 1. Track tension and alignment adjustment may be required if the track starts to skip on the drivers or if the rail slides are wearing too quickly. For more information on track tension and alignment refer to the Track Maintenance section (page 81).
  • Page 66 MAINTENANCE WARNING DO NOT adjust the brake lever closer than 1/2 in from the handlebar. Adjusting the lever closer than 1/2 in could prevent the brakes from functioning properly resulting in severe injury or death. WARNING Do not remove the brake lever boot. 1.
  • Page 67 MAINTENANCE HAND-GUARD Timbersled snow bikes are equipped with a Brembo® Master Cylinder Hand Brake. Only use Timbersled-approved hand guards. WARNING Make sure gauntlets and other hand protection accessories do not come in contact with the brake lever. Any brake lever contact can create pressure in the brake system and cause it to overheat and fail.

  • Page 68: Brake Components

    MAINTENANCE BRAKE COMPONENTS Brake Caliper Brake Pad Material Brake Disc 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 69: Bleeding The Hydraulic Brake System

    MAINTENANCE WARNING Keep the master cylinder cover free of dirt and debris. The vent slits allow for diaphragm movement, and if they become plugged, movement of brake fluid below the diaphragm may be restricted, altering brake function. NOTICE Brake fluid will damage labels, paint and some plastics. Always wipe up spills immediately.

  • Page 74 MAINTENANCE 1. Remove fasteners from chain case cover. 2. Position a ruler behind or in front of the right chord of the drive chain halfway between the drive shaft sprocket and the jack shaft sprocket (this is where the chain’s displacement should be measured). Position and steady the ruler so it does not move as chain displacement is measured.

  • Page 75: Chain Inspection

    MAINTENANCE 1. Loosen the tension roller bolt 2. Adjust the chain tension as needed by pushing the roller bolt towards the chain to increase tension or away from the chain to lessen tension. 3. Then tighten the tension roller bolt firmly once again.
  • Page 76 MAINTENANCE 2. Mark out the number of links to measure (see the following table to find the number of links to measure for the chain you are inspecting). To mark this number of links, begin by marking the first pin and counting forward the same number of pins (number of pins counted should equal the number of links to measure).
  • Page 77 MAINTENANCE 3. Then measure the counted number of links by measuring from the center of the first pin to the center of the final pin . This measurement should equal a length somewhere within the acceptable length range (as shown in the previous table). 4.
