PROBLEM CAUSE AND SOLUTION
cutting System
Cutting drum doesn’t rotate when activated. • Lift arm and cutter are down. The last action
of the lift arm must be up before the cutting
drum will rotate.
• OMSI PTO is engaged. Engage OMSI PTO
• Hydraulic fluid low. Add fluid to the hydraulic
fluid reservoir.
• Hose or fitting broken or leaking. Tighten loose
fitting or replace broken hose or fitting.
Cutter kicks back or jumps when the cutter
teeth hit the pavement.
• Down pressure is not set high enough. Raise
down pressure.

• Down pressure set to high. Lower down
pressure.
Cutter hits pavement during the skip cycle
during cutting operations.

wheel cylinder rams to increase cutter clearance
when the skip cylinders are engaged.
