START-UP PROCEDURES
1) Check oil level in gearbox and in speed reducer if
so equipped. Adjust to required oil level as per
drawing in Parts List section. Use SAE 80W90
oil.
2) Lubricate all points with a good quality
multipurpose grease.
3) Check chain take-up adjustment. The spring
maintaining the tension must be compressed to a
length between 3 1/4" and 3 1/2".
4) Verify for adequate tightness of all fastening
devices. Refer to torque chart on page 43.
5) Adjust skid shoes according to ground conditions
(Fig. 19).
6) Following the installation of the Snowblower on
the tractor, do not forget to lift the storage sup-
port (Fig. 20).
7) Use 540 RPM drive line or if your snowblower is
eqyupped with a 1000 to 540 RPM speed reducer,
use 1000 RPM drive line.
8) Check oil level in auger drive chain box (Fig. 21).
Fill to level of plug. Use SAE 80W90 oil.
9) Check impeller adjustment. The tip of the blades
should be approximately 1/8" to 3/16" from the
discharge wall of the drum. If necessary, adjust
with the take-up screws provided (Fig. 22).
10) In order to avoid damaging your snowblower,
adjust the speed of descent of your 3 point hitch to

dirt and sand.
2) Repair or replace damaged grease fittings.
3) Lubricate all grease fittings every 10 hours of
operation.
4) Oil drive chain every 8 hours of operation.
5) Lubricate P.T.O. shaft as indicated below:
Pull out the P.T.O. And lubricate between the two
tubes with low temperature grease.
6) Check oil level in gear box once a month. Adjust
to required oil level as per drawing in Parts List
section. Use SAE 80W90 oil.
7) Check oil level in auger drive chain box once a
month. Fill to level plug. Use SAE 80W90 oil.
8) Check tension of drive chain every 24 hours of
operation and adjust if necessary.
9) Check for tightness of bearing collars every 48
hours of operation.
10) Change gearbox oil once a year. Adjust to required
oil level as per drawing in Parts List section. Use
SAE 80W90 oil.
11) Check all nuts and bolts once a year. If necessary
use torque chart on page 43.
12) Standard scraper blades are reversible. Reverse
when one edge is worn out.
13) For the auger drive shaft, always use a grade 5
shear bolt.
14) For the PTO shaft, always use a grade 10.9 shear
bolt at 540 RPM or a grade 8.8 shear bolt at 1000
RPM.
15) UHMW slides do not require lubrification except
at the end of the season in order to prevent corro-
sion of steel components that are in contact with
the UHMW material.
If your snowblower is equipped with the optional
speed reducer
16) After 10 working hours, the chain's adjustment (if
applicable) must be checked and every 100
working hours. Please refer to section: Mainte-
nance on Speed Reducer.

MAINTENANCE ON SPEED REDUCER
It is extremely important that the chain inside the
chain box is tightened. A loose chain will add shocks
to the entire box (chain, sprockets, bearings and spline
couplings to gearbox).
Instructions for speed reducer (with chains) main-
tenance
This chain box has double functions.
1) Reduce angles at both ends of PTO in working
position by increasing the input shaft height of 8".
2) Increase PTO capacity by increasing speed from
540 RPM to 1000 RPM.
ADJUSTMENT OF THE CHAIN'S TENSION
After 10 working hours, the chain’s adjustment must
be checked. In order to do so, verify the backlash
between the input and the output shaft by turning the
input shaft in both directions while the output shaft
remains still. If there is a play of 10° or more, the
chain must then be readjusted as follows:
1) Remove PTO from the chain box.
2) Unscrew the 12 bolts 5/16" dia. (item #22)
from covers (items #7 and #15) around the
input shaft on both sides of the chain box (6
bolts on each side).
NOTE: Input shaft covers are eccentric with
outside of covers. Therefore by turning input
shaft cover, center to center distance of shafts
will be changed and thus, this will adjust the
chain’s tension.
3) With a hammer and a screw-driver or a chisel,
gently turn both covers in the same direction
until the next hole of the cover is in line with
the threaded hole of the chain box.
IMPORTANT: Make sure that the covers
are turned in the same direction and by the
same number of holes.
Otherwise, both shafts will not be parallel
and serious damages might arise.
4) Verify the backlash between both shafts, as
described above. If the difference is too high,
repeat the operation explained in point 3. If
the backlash is correct, reinstall the bolts and
the PTO.
5) Verify the backlash every 100 working hours.
MAINTENANCE ON SPEED REDUCER
1) Check oil level in speed reducer once a month.
Adjust to required oil level as per drawing in
Parts List section. Use SAE 80W90 oil.
2) Drain the oil of the speed reducer once a year.
Adjust to required oil level as per drawing in Parts
List section. Use SAE 80W90 oil.
