740, 840 & 840G Snowblowers
10
OPERATING INSTRUCTIONS
1. Do not operate the blower in the fully raised position. The three-point hitch on
some tractors raises high enough to cause the PTO shaft to bind. This can
cause damage to the PTO shaft and/or to the hitch and pins.
NOTE: PTO shaft angle should not exceed 20 degrees for optimum
performance and life. Damage may occur to PTO and/or Snowblower if
angle becomes more extreme.
2. Depth of cut can be partially controlled by tilting the blower forward or backward.
Adjust the top link of the tractor hitch so the snowblower is just slightly tilted back
when resting on the ground.
Caution: Excessive backward tilt may cause
the "U” joints to flutter resulting in PTO shear bolt failure.
3. Adjust the lower link sway chains or blocks on the tractor to restrict side
movement of the blower when operating.
4. Run the blower at low rpm to check operation before blowing snow.
5. The snowblower has two 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 5) Auger
shear bolt (1/4" x 1"-Grade 5). Shear bolts should be fastened with a lock nut or
two jam nuts. These bolts must be kept tight to prevent wear of the bolt and bolt
holes.
6. Never run PTO shaft at over 600 rpm.
7. Chain tension: Slack on the lower side of the chain should be 3/8 to 1/2 inch.
8. Lubrication:
a) The spout clamps and rings should be periodically lubricated with
gun grease.
b) PTO shaft universal joints and square shaft slide should be greased daily.
c) Regularly oiling the chain will significantly increase the life of the chain.
d) The grease fitting on the hydraulic spout swivel arm should be kept
lubricated.
e) For #740 & #840 only: Gearbox is open type and need not be greased
or lubricated.
For #840G only: See Section on refilling for correct oil level.
Use any 80-90 gear oil or multigrade with 80 minimum.
