Hydraulic Relief Valve Adjustment
The fan is shear-protected by the loader
hydraulic system pressure relief valve. No
adjustments are required.
The auger is shear-protected by pressure relief
valve ‘A’ located in the hydraulic control
manifold on the rear of the snowblower, directly
above the fan motor.
NOTE:
The auger relief valve is set at the
factory to assure the best performance in
average conditions. If the auger should stall too
easily, the relief valve can be adjusted as
follows:
1.
Loosen the lock nut on valve ‘A’.
2. Turn the set screw one turn.
3. Tighten the lock nut.
4. If the auger still stalls, adjust the relief valve
again by repeating steps 1 through 3.
NOTE:
Do not adjust the relief valve more than
one turn at a time or a total of more than 4
turns. If the auger still stalls, look for other
problems.
