Do not allow anyone to ride on the DR® SNOW THROWER. Skid Shoe Adjustment (Figures 8 & 9) ! 3.
OPERATION General Preparation Snow Removal 1. Use a winter grade oil in your DR® ALLTERRAIN™ MOWER. See the engine manufacturer's owner's manual. Never use the DR® SNOW THROWER as a snowplow. Do not push the snow, let the SNOW THROWER work its way through deep drifts. For best results, raise the SNOW THROWER and remove a top layer of snow. A second pass will remove the remaining snow. 2. Make sure that the auger operates freely. 3. Adjust the skid shoes so that the DR® SNOW THROWER runs level. 4.
OPERATION Snow Removal Methods When removing snow, do not use the DR® SNOW THROWER as a dozer blade to push snow. Let the DR® SNOW THROWER work its way through deep drifts. If the speed of your DR® ALL-TERRAIN™ MOWER is too fast, the DR® SNOW THROWER may become overloaded and clog. For best results, raise the DR® SNOW THROWER and remove the top layers of snow, or take a half-width pass. A second pass with the DR® SNOW THROWER will remove the remaining snow.
MAINTENANCE ALWAYS USE GENUINE PARTS WHEN REPLACEMENT PARTS ARE REQUIRED ! WARNING: Never park the DR® ALLTERRAIN™ MOWER with fuel in the fuel tank inside a building where an open flame or sparks are present. Allow the engine to cool down before storing in any enclosure. Drive Belt Replacement (Figure 4, Page 12) When the belt tensioner is 1/8" close to its support (see figure below) due to belt elongation or after the equivalent of 60 hours of continuous operation, replace the drive belt.
MAINTENANCE Shear Bolt Replacement (Figure 11) If you strike a foreign object (wood, stone, etc.) there is a safety shear bolt on the driving system. This shear bolt will break, eliminating any driving force to the auger. ! WARNING: Always disconnect the spark plug wire before servicing your machine. 1. To replace the shear bolt, stop the DR® ALL-TERRAIN™ MOWER and remove the spark plug wire. 2. Remove the bolts (item 1), and remove the belt cover (item 2). 3.
