Cutting Edge Height
•
In order to prevent damage to in-pavement lights and to protect vehicle operators from uneven pavement joints and
edges, the plow blade / cutting edge should be set slightly above ground level.
•
In a stationary position the clearance between the plastic cutting edge and the pavement should be 10 to 15 mm. Any
remaining snow/ice should be removed with rotary brooms and/or de-icing or anti-freeze agent. No clearance between
the plastic cutting edge and the pavement may damage in-pavement lights.

•
Use casters, shoes and/or support wheels on plow moldboards and on the front of rotary plows to stabilize the plow
blade and to support maintaining a pre-defined clearance between the snowplow cutting edge and the pavement during
operation.

•
Do not use guidance and support wheels that are made of steel.
•
Any protruding bolts and metal elements whose clearance to pavement is less than 20 mm during operation shall be
avoided
