SKID SHOE ADJUSTMENT
• Theskidshoesaremountedoneachsideofthespiral
auger housing. They regulate the distance the scraper
plateisraisedabovetheplowingsurface.When

surface,itisadvisabletokeepthescraperplateas
highabovethesurfaceaspossibletopreventpossible
damage to the spiral auger. On blacktop or concrete
surface, keep the scraper plate as close to the surface
as possible.
• Raisethesnowthroweroffthegroundandplacea
block under each end of the scraper plate. Loosen the
six hex nuts securing the skid shoes to the housing.
Adjust the skid shoes up or down and retighten the
nuts securely. Adjust both skid shoes to the same

SPIRAL AUGERS
• Thespiralaugersaresecuredtotheaugershaftwith
two shear bolts and nylock nuts. If you hit a foreign
object or if ice jams the augers, the snow thrower is
