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 16 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 immediately, remove the obstruction, and inspect it for damage. Repair or replace any damaged parts before restarting and operating you snow thrower.
Attention: Release (disengage) the auger and drive control lever (handles) before adjusting the drive speed control lever. NEVER change the drive/gear speed while your snow thrower is in motion, as it will damage the drive mechanism and void the warranty. DRIVE SPEED/GEAR CONTROL Move the drive speed control lever to the desired speed. There are six (6) settings: four (4) forward speeds and two (2) reverse speeds. 1 is the slowest forward speed and 4 is the fastest forward speed.
OPERATING YOUR SNOW THROWER MANUAL START THE ENGINE To manual start the engine, perform the following steps: 1. Check the oil and fuel levels. 2. Turn the fuel valve to the “ON” position. 3. Move the choke lever to the “CLOSE” position. 4. Make sure insert the switch key. 5. Press the primer bulb 3 times. 6. Pull on the recoil starter handle slowly until a slight resistance is felt, then pull quickly to start the engine. Return cord gently into the recoil starter. Never allow the cord to snap back. 7.
3. Engage/depress the drive control lever (handle) and direct the snow thrower into the snow to be cleared. NOTICE: NEVER change speed/gear positions while the drive control lever (handle) 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.
MAINTENANCE WARNING! Never perform maintenance while your snow thrower is running. Turn OFF the engine before performing any maintenance tasks on your Snow Thrower. Proper maintenance of your snow thrower will help prolong its life. Please perform the following maintenance procedures as required. Please read the ENGINE manual for engine maintenance procedures.
