It is the responsibility of all operators to read and understand this entire manual before installing, operating or servicing the PREMIER Ammbusher Heavy Duty Brush Cutter. Pay particular attention to cautions, warnings and safe operating procedures. Be a safe and qualified operator. Operate your equipment with care and good judgment and see to it that it is properly maintained.
Do not raise the back of the PREMIER Brush Cutter (nearest operator) over 2 feet off the ground. Never expose yourself or a bystander to the rotating blades. When driving the loader to and from the worksite, carry the PREMIER Brush Cutter as low as possible to the ground to avoid the possibility of tipping forward.
Release the locking levers and disengage the loader mounting plate. OPERATING INSTRUCTIONS The PREMIER Ammbusher Heavy Duty Brush Cutter is capable of cutting trees and vegetation of varying height up to 7” in diameter. Designed to make your loader more versatile, the PREMIER Ammbusher Heavy Duty Brush Cutter is intended to perform these functions without the front of the mower deck being raised to a vertical height greater than 3 feet.
REPAIR AND MAINTENANCE PART “A” BLADE CARRIER REMOVAL This operation should be performed by an authorized dealer or a qualified technician. The blade carrier weighs approximately 600 pounds. Should it unexpectedly shift during removal, it could result in personal injury. An overhead hoist with the appropriate lifting capacity is recommended for this operation.

Repeat the above process on all 3 remaining blades. NOTE: Only use genuine PREMIER Ammbusher replacement parts. It is recommended to flip all blades at the same time. Blades should be replaced in pairs on opposite sides of the blade carrier to maintain balance.
