Emergency Operation
VERTICAL AUGER HYDRAULIC STOP
The Zamboni Company Ltd. Model 445 Ice Resurfacing Machines are now equipped with
a vertical auger hydraulic stop valve. The valve is controlled by a normally open electrical
switch located near the front of the snow tank.
It functions as follows:
1) When the snow tank is down, the valve is open allowing ow to the
hydraulic motor that rotates the auger.
2) When the snow tank is raised, the valve is closed thereby blocking ow
to the hydraulic motor.
3) Do not try to reverse the vertical auger with the snow tank up. Doing
so will put a large strain on the motor to auger coupler causing it to break.
In order for the system to function in a safe manner, the solenoid valve will be powered
at all times when the machine is running and the snow tank is in the down (operating)
position. The coil on the valve may become hot depending on the length of time that the
machine is in operation.
