forward of the cutting drum. Water cools the drum
and reduces dust during operation. Always make
sure the water system is activated and supplying
water to the cutter when rumble stripping or plan-
ing operations are underway.
WARNING
THE CUTTING DRUM AND TEETH AND ARE EXPOSED WHEN
THE CUTTER IS RAISED BY THE LIFT ARM. AN EXPOSED
ROTATING CUTTER CAN BE EXTREMELY DANGEROUS AND
CAUSE SEVERE INJURY TO PERSONNEL. ALWAYS MAKE
SURE ALL PERSONNEL ARE WELL CLEAR OF THE CUTTER
BEFORE RAISING THE LIFT ARM WITH CUTTING DRUM
ROTATING OR ENGAGING THE CUTTING DRUM WITH THE
UNIT RAISED .
DANGER
A ROTATING CUTTING DRUM CAN CAUSE SEVERE INJURY
OR DEATH IF HANDS, FEET OR LOOSE CLOTHING ARE
CAUGHT BY THE TEETH. ADDITIONALLY, LOOSE TEETH
OR DEBRIS STUCK IN TEETH CAN BE THROWN FROM THE
DRUM WITH ENOUGH FORCE TO CAUSE INJURY.
ALWAYS MAKE SURE THE SAFETY SHROUD IS PROPERLY
INSTALLED AND THE CUTTER CHASSIS IS ON THE GROUND
BEFORE MAKING ANY ADJUSTMENTS WITH THE CUTTER
ENGAGED. NEVER ALLOW ANYONE TO STAND NEAR OR
BEHIND THE CUTTER WHILE THE DRUM IS ROTATING WITH
THE SAFETY SHROUD REMOVED.
DANGER
ALWAYS MAKE SURE AN OPERATOR IS IN THE DRIVER
SEAT AND MONITORING THE CUTTER AND ANY PERSONNEL
NEAR THE CUTTER WITH THE VIDEO SYSTEM WHENEVER
CUTTING DRUM IS ROTATING. THE OPERATOR MUST
BE VIGILANT AND PREPARED TO SHUT THE MACHINE
DOWN IMMEDIATELY IF A PROBLEM OCCURS WHILE
ADJUSTMENTS ARE BEING MADE TO THE CUTTER WHILE
THE DRUM IS ROTATING.
Cutter Eccentric
The cutting drum is mounted to a rotating eccen-
tric system driven by two drive belts, one on each
side of the cutter. The drive pulleys for each belt
are connected to an axle that is driven by another
drive belt and hydraulic motor. The eccentric hy-
draulic motor is powered by a dedicated hydraulic
pump driven by the OMSI PTO. Drive belt ten-
sion is critical to proper operation and should be
checked frequently and adjusted as required.
Cutter Eccentric
The eccentric causes the cutting drum and teeth
to plunge and lift at a specific depth and height.
Eccentric RPM is variable and determines the cut
spacing value between the rumble strips. RPM
is calculated by the controller and indicated as a
percentage of the cut width which sets the dis-
tance between each cut. Cutting depth is set by
adjusting the rear guide wheels up or down using
adjustment bolts on the cutter chassis.
Refer to the Operation section for instructions on
programming the cut spacing value.
