Starting the Drum Mulcher
IMPORTANT
At the sign of any unusual vibrations during
operation, stop and inspect for loose,
damaged or missing cutting teeth.
CAUTION
The cutting drum must not exceed 2400
rpm. Serious damage can result.
Install the drum mulcher onto the machine.
Move to the operator’s position, lower seat bar,
start the engine and release the parking brake.
Raise the drum mulcher slightly off the ground to
allow the mulcher drum to rotate freely.
With the machine’s engine RPM just above idle,
engage the auxiliary hydraulic flow (see the
machine’s operator’s manual) to the drum
mulcher. Allow the hydraulic system to properly
warm up.
Slowly raise the machine’s engine RPM to the
correct maximum speed and begin mulching.
