1. Verify attachment is secure with coupler levers in the locked position and
pins are fully engaged into ange slots. Ensure hydraulic hoses are locked
to couplers.
2. Set skid steer engine RPM to slightly above idle.
3. Activate skid steer auxilary hydraulic circuit.
4. Once brush cutter is up to speed, increase skid steer engine to full throttle.
Ensure cutter is running smoothly.
Starting the Cutter
Your brush cutter is designed to run o the skid steer loaders auxiliary

with the control handles or pedals in the cab. Consult your skid steers
operator’s manual for precise instructions regarding these functions.
Hydraulic Flow Requirements
When operating the cutter, set the skid steer throttle at a speed that will
produce the required ow. Your skid steer dealer can measure the ow
available on your machine and recommend a throttle setting that is compatible
with this attachment.
Brush Cutter Controls

3.3 How To Start and Stop The Brush Cutter Cont.
If the brush cutter begins to vibrate while increasing the RPM’s, ip the
auxiliary hydraulic switch to the OFF position and investigate the cause.
Refer to the Troubleshooting Chart on page 35 of this manual.
Stopping the Cutter
