MAINTENANCE
AUGERS
The augers are secured to the spiral shaft with two
hex boits and hex lock nuts (see Ref. Nos. 40 and
50 on page 24). if you hit a foreign object or ice
jam, the snow thrower is designed so that the hex
bolts will shear.
If the augers will not turn, check to see if the hex
bolts have sheared. Two replacement hex bolts
and hex lock nuts have been provided with the
snow thrower. For future use, order part number
710-0891 (hex bolt 5/16-18 x 1.75" long) and
712-0429 (hex insert lock nut 5/16-18 thread).
SHAVE PLATE AND SKID SHOES
The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when
necessary. Skid shoes and shave plate are revers­
ible for longer life. The skid shoes may also be in­
verted to extend their life even further.
To remove shave plate, remove the carriage boits,
lock washers and hex nuts which attach it to the
snow thrower housing. Reassemble new shave
plate, making sure heads of the carriage bolts are
to the inside of the housing. Tighten securely.
To remove skid shoes, remove the four carriage
bolts, believille washers, and hex nuts which at­
tach them to the snow thrower. Reassemble new
skid shoes with the four carriage bolts, believille
washers (cupped side goes against skid shoes)
and hex nuts.
