PRE-SALE SERVICE AND SETUP OF BLOWERS
1.Turn hood to point directly behind blower.(PTO side)
2.Lift hood assembly off and spread a light coat of grease
on outside of blower mainframe pipe.
3.Replace hood assembly.
4.Install hood turner as per instructions.
5.Grease shear assembly, auger bearings, and hydraulic
hood turner if installed.
6.Check oil level in gearbox.
7.Check all bolts for tightness.
8.Check auger drive chain tension and alignment.
Adjust if necessary.
9.Grease PTO universal joints, shield retaining collars,
and inner tube of PTO.
OPERATION
1.When attaching the blower make certain all guards are in place.
2.Ensure that the fan and auger rotate freely before connecting PTO shaft to the tractor.
3.Use proper pins and ensure that all connections are secure.
4.Engage the PTO at low engine RPM and slowly increase speed to operating level. Operating speed will vary with snow,
weather, and ground conditions.
5.Adjust the top link of the three-point hitch to match the ground and snow conditions. Increasing the length will cause the
blower to cut deeper into compacted snow, but may also cause the blower to scrape gravel or stones into the fan, which can
be a danger to nearby persons, pets, livestock or buildings. Decreasing the length of the top link causes the blower to ride
back on the skid shoes, raising the cutting height, thereby reducing the possibility of scraping gravel or stones into the blower.
6.Adjust the deflector for the distance of throw required. Moving the adjusting bar, to shorten the distance between the pins
increases the distance thrown.
7.Be aware of the presence of people and objects that may be obscured from vision by blowing or drifted snow. Be certain that
no children have tunnelled into snowbanks which are to be removed. Never let children slide down snowbank in the vicinity
of an operating blower.
SERVICE
1.Before servicing or adjusting, disengage the PTO, lower the unit to the ground, and shut off engine.
2.To prevent freezing of hood or other moving parts apply a solution of antifreeze or light oil.
3.Check gearbox oil level on a regular basis. If oil level is low, use a good quality 80W-90 gear oil. Change oil after 50
hours during break-in period. Change after 700-750 hours or yearly.
4.Grease the shear assembly and hydraulic hood turner every five hours of operation.
5.Grease the auger bearings every ten hours of operation.
6.Check auger drive chain tension and alignment. Adjust if necessary.
INSTALLATION INSTRUCTIONS FOR SNOWBLOWER
FOR A BETTER P.T.O. SHAFT & GEARBOX OPERATION
A proper initial installation will give you years of satisfactory service on your equipment. Please read carefully
following instructions which have been specially made to help you and make you satisfied with your purchase.
WARNING:
Unfortunately, snowblowers
will
be
faced
with
forgotten
or
hidden
objects
under
the
snow,
such
as:
chain,
tires,
stones,
pieces
of
wood,
etc
…
In
spite
of
all
our
efforts,
machines
are
not
built
to
resist
all
those
conditions.
DANGER: TOO BIG TRACTOR
It is dangerous to use a tractor which is too big or too powerful. The tractor will always be able to overload the
blower, even if the machine is already at maximum capacity. Tractor being very high, too large angles at P.T.O.
universal joints will result, and life of universal joints will be shortened dramatically.
