Always place containers on the ground away from your vehicle before filling. • If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground.
• Disengage power to the auger impeller when transporting or not in use. • Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up. • If the machine should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.

Spring Locking Pin Step 3 – Skid shoes installation and adjustments 1. Locate the pair of skid shoes from parts bag and remove the bolts. 2. Loosely install the skid shoes using the bolts and hex nuts as shown on each side of the auger housing. Make sure the skid shoe tip faces out.
SNOW THROWER PREPARATION ADD OIL The snow thrower is shipped without oil. User must add the proper amount of oil before operating the snow blower for the first time. The oil capacity of the engine crankcase is 20 fl. oz. For general use, we recommend 5W, 4-stroke engine oil. ENGINE OIL RECOMMENDATIONS Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications SJ, SL, or SM (synthetic oils may be used).
WARNING! Keep the area of operation free from foreign objects that can be thrown by the auger and/or impeller blades. Perform a thorough inspection of the area since some objects may be hidden from view by surrounding snow. If the Snow Thrower hits an obstruction or picks up a foreign object during use, stop the Snow Thrower, remove the obstruction, and inspect it for damage. Repair or replace any damaged parts before restarting and operating you Snow Thrower.
AUGER AND DRIVE CONTROLS 1. To engage the auger, press down on the auger control handle (left side handle). 2. To engage the drive, press down on the drive control handle (right side handle). The machine should start moving in the direction and speed that the speed control lever is set to. 3. When finished clearing a snow path, release the auger control handle and the drive control handle. Attention: Release (disengage) the auger and drive control handles before adjusting the drive speed control lever.
NOTICE: Do not change speed positions while the drive is engaged. Disengage the drive control handle BEFORE changing speeds or directions. If the snow is deeper than the height of the auger, remove it in several steps taking narrower swaths. Make several passes with the auger overlapping the cleared areas and reduce forward speed. For the best clearing efficiency, clear snow before it melts, refreezes and hardens. Hard packed and wet snow can be very difficult to clear.
MAINTENANCE PROCEDURES TIRE INFLATION Before each use of your Snow Thrower, check the tire pressure. The pressure in each tire should be in the range of 20-24 psi for the best performance. The pressure can be checked using an ordinary tire pressure gauge. Fill the tires using a small or pressure regulated air compressor. WARNING! DO NOT OVER-INFLATE THE TIRES. Over-inflating could cause a tire to burst and cause severe bodily injury.
TROUBLESHOOTING Problem Causes Remedy WARNING - Before attempting to make any inspections, repairs or adjustments, stop the engine, wait for all moving parts to stop moving and carefully disconnect the engine spark plug wire. If tipping or turning the snow blower is required for any inspection or repair, first wait until the engine is cool to the touch and then drain the engine of all fuel and oil into suitable containers and store or dispose of in a proper manner.
