OPERATION Engaging the Auger Blades 1. To engage the auger blades, hold the control bar against the handle (Figure 13). IMPORTANT: During initial operation there may be wear between the auger blades and the scraper bar. Maximum performance, both snow throwing and driving, occurs when there is zero clearance between these two parts (Figure 15). 1 During initial break-in period of the auger blades it is normal for the auger blades to build up excessive heat if not operated in the snow. Do not operate without snow or water for lubricating the auger blades. This will cause excessive heat build up in the auger blades which could cause damage to the auger blades and scraper bar.
