TO REPLACE BELTS (See Fig. 25)
The auger and traction drive belts are not adjustable. If the 

belts are damaged or begin to slip from wear, they should 

be replaced. It is recommended that the belt(s) be replaced 

by a qualified service center.
NOTE: It is recommended that both the auger and traction 

drive belt be replaced at the same time.
The V-belts on your snow thrower are of special con struc tion 

and should be replaced by original equipment man u fac tur er 

(OEM) belts avail able from your nearest dealer. Using other 

than OEM belts can cause personal injury or damage to 

the snow thrower.

the square hole in idler arm and rotate ratchet clockwise 

to relieve tension.
