SAFETY
• NEVER SERVICE A MACHINE WITH THE ENGINE RUNNING, SEVERE
PERSONAL INJURY COULD OCCUR. TURN ENGINE OFF THEN REMOVE
IGNITION KEY AND DISCONNECT POSITIVE BATTERY CABLE TO AVOID
STARTING MACHINE ACCIDENTALLY.
• CUTTER WHEEL MUST BE DISENGAGED BEFORE TURNING ENGINE
ON/OFF AND BEFORE SERVICING A MACHINE. OTHERWISE SEVERE
PERSONAL INJURY COULD OCCUR AS WELL AS MACHINE DAMAGE.
• ALL MACHINE PARTS MUST COME TO A COMPLETE STOP AND HAVE
TIME TO COOL COMPLETELY BEFORE SERVICING A MACHINE OR
SEVERE INJURY COULD OCCUR, POSSIBLY SERIOUS BURNS AND/OR
DISMEMBERMENT.
• PLACE THE CUTTER WHEEL ON THE GROUND WHEN PERFORMING
SERVICE ON A MACHINE.
• Swing the cutter wheel to the right to
access the boom pivot grease fitting.
Grease boom pivot monthly. Do not
over grease. There is a Pop-Out Valve
above the grease fitting, if the pin pops
out enough grease has been applied.
Wipe off excess grease. Excess grease
will attract dirt.
• The boom pivot is equipped with a
hardened shaft and Timken® roller
bearings. If the boom becomes loose,
you will need to apply pressure to the
bearings to tighten it. To apply more
pressure to the bearings, hold the bottom
nut where the cotter pin is. Remove the
first nut and tighten the second nut,
which will apply pressure to the roller
bearings and the boom swing. You can
place cutter wheel on ground and put
slight pressure on cutter wheel to adjust
pivot bearings.
If the main pivot bearings need replacing, you will have to remove the top pin and slide the main
pivot out and install the new bearings. See Upper Pivot Assembly for breakdown.
• Boom must be placed in a fixture to hold steady when you remove the pivot pin.
