First Aid Kit

• A first aid kit should be the first thing you put into your tool kit. The effects of an injury can drastically be magnified in a cold, remote location. A first aid kit should contain common items, such as bandages, but because of the potential for injury in remote locations, include other, less common items . These include a cell phone, fire-starting equipment, space blankets and mirror-signalling devices. A flashlight is also a necessity. The best way to handle a trail-side emergency is to be properly prepared for one.
  
  

Spark Plug Socket

• In the event that your snow-machine experiences an engine-related failure, there is a good chance that the spark plug is at fault. Test the spark plug socket before sticking it into your tool kit. It must be long enough to reach the base of the spark plug. If the socket is too short, it could slip and break the spark plug. You don't want to find out it won't fit when you most need it. Carry extra spark plugs. Set the gap on the new plugs before you put them in your tool kit.
  
  

Wrenches

• Grab a set of wrenches and test-fit one to each bolt on your snow-machine. Set aside every wrench that fits critical components, such as the front ski bolts and the rear track components. After doing this, you will have a small pile of wrenches that fit every bolt on your machine. Line up the wrenches on a table, starting with the ones that fit the most critical components. Use these in your tool kit and add the other wrenches as space permits. It may be tempting to bring a ratchet and sockets instead of the wrenches. These can work, but the ratchet uses a mechanical drive. If this is damaged, you cannot use the sockets.
  
  

Locking Pliers

• Quality locking pliers are essential for your snow-machine. Many engine failures are fuel related. Locking pliers will allow you to remove fuel-line clamps and fuel lines for cleaning or replacement. They also have the ability to act as a locking clamp. It the snow-machine experiences a break between two, once-joined parts, the locking pliers can hold those pieces together. This will often allow the vehicle to reach safety under its own power.
  
  

Saw

• Include a saw to clear a trail of downed trees. A saw is also essential for help in gathering firewood. Many snow-machine trails are through wooded terrain. The possibility of a downed tree in the trail is high. A saw can also fell trees in an effort to free a stuck snow-machine. You can use a straight tree to lever a stuck machine out of a soft spot. Get a saw that folds, for easier storage in your tool kit.
