OPERATING INSTRUCTIONS – cont’d.
7.
ALL: Run the snowblower at low rpm to check operation before blowing snow.
8.
PTO DRIVE: The blower has three shear bolts to protect the tractor and blower
in case a large object enters the blower. PTO shear bolt – two 5/16” x 1”
(grade 8); auger shear bolt – 5/16” x 1 ¼” (grade 5). Shear bolts should be
fastened with a lock nut or two jam nuts. These bolts must be tight to prevent
wear of the bolts and bolt holes.
9.
PTO DRIVE: Never run PTO at over 600 rpm.
10.
ALL: Chain tension on auger chain should be set at 3/8” to 1/2” slack.
11. LUBRICATION:
a)
ALL: The gear teeth on the chute control should be periodically
lubricated with gun grease.
b)
PTO DRIVE: PTO shaft universal joints and square shaft slide
should be periodically lubricated with a grease gun.
c)
ALL: Regularly oiling the chain will significantly increase the life
of the chain.
d)
PTO DRIVE: Use any 80-90 gear oil or multigrade with 80 minimum
in the gearbox up to the level plug height.
12.
ALL: Periodically check all bolts for tightness. The bolt holding on the fan
and the bearing bolts are of particular importance.

hydraulic leaks. Use a piece of cardboard instead of your hands to look
for leaks.
14.
ALL: Always shut off snowblower for servicing or unplugging.
Disengage hydraulics or PTO shaft.
15.
PTO DRIVE: Check the shear sprocket at the beginning of every season
to make sure it will spin freely. Clean to loosen if necessary.

tighten collar in the direction of shaft rotation using a center punch or a
similar tool.
