Rumble Stripping Do’s and Don’ts
Do’s:
• Mount video monitors to windshield before start-
ing cutting operations.
• Align truck, set guidance indicators and cutter
offset before start cutting operations.
• Make sure the proper teeth for rumbling are
installed in the cutting drum.
• Inspect cutter for worn or missing teeth before
each shift.
• Set down pressure at the start of each job.
• Check cutter depth before starting each shift.
Remember that cutter diameter decreases as
teeth wear. Adjust standoff height if necessary.
• Shift truck to work mode in the proper sequence.
• Engage eccentric and cutting drum before lower-
ing cutter to the pavement.
• Raise lift arm before engaging eccentric and cut-
ting drum. Cutting drum will not rotate unless
the last lift arm motion is UP.
• Make several short test runs at the beginning
of each job to verify correct down pressure, cut
spacing, cut pattern and cutter operation.
• Reduce down pressure if gauge wheels damage
pavement or truck experiences traction issues.
• Raise the cutter before changing direction or
making sharp turns.
• Engage water pump before starting cutting
operations.
• Control truck WORK mode speed with TRUCK
SPEED dial not the joystick during cutting op-
erations.
• Monitor truck and cutter alignment during cut-
ting ope rations.
• Raise cutter off pavement while crossing bridges,
intersections, driveways.
• Look well ahead off the truck while cutting. Begin
bumping cutter right or left to clear objects well
before reaching the object.
• Bump cutter right or left in no more than .25”
increments when clearing objects.
• Monitor video screen vacuum cup plungers dur-
ing operation. Pump the plunger if red line is
showing.
