Page 2 TO THE OWNER/OPERATOR/DEALER All implements with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded operator who recognizes the potential hazards and follows reasonable safety practices. The manufacturer has designed this implement to be used with all its safety equipment properly attached to minimize the chance of accidents. BEFORE YOU START!! Read the safety messages on the implement and shown in your manual.
Page 3 In order to reduce accidents and enhance the safe operation of mowers, Alamo Industrial, in cooperation with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety Practices video and guide book. The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and agricultural mowing equipment.

Page 17 Always disengage the Grizzly before leaving the machine. Place the Control Valve in the OFF position and disengage the power take-off. Shut off the engine.

INTRODUCTION SECTION Introduction Section 2-1...
Page 26 This machine is not recommended for use in populated and built-up areas. The Grizzly utilizes hydraulically driven rotating steel blades, rotating disc with cutter bits, or a rotating arbor with flail hammers. It is usually mounted on the hydraulic boom arm of a tractor, excavator or similar carrier, and employs the hydraulics system of the carrier for operation of the hydraulic drive motor.
Page 27: Safety First
Suited for clearing roadway or off-highway right-of-way, clearing of power line underbrush, pipeline right-of-way and forestry thinning in dense growth, the Grizzly is both efficient and environmentally acceptable. The Grizzly is so efficient that the operator can pass from dense brush cutting to grass cutting with the same machine.

ASSEMBLY SECTION Assembly Section 3-1...
Page 30: Pre-Installation
The control valve must be of the motor spool type that will allow the Grizzly to gradually slow to a stop rather than "lock up" when the control is moved to the "OFF" position. If a motor spool equipped control valve cannot be provided then a system of circulating check valves must be used in the vicinity of the drive motor.

Page 36: Pre-Startup (Daily Check List)
Rules, Precautions and Operating Functions of both Tractor (carrier) and the Alamo Grizzly. Do not operate the carrier or the Grizzly when tired, ill or under the influence of drugs, alcohol or medication. The greatest danger when operating the machine is the possibilty of the cutting head throwing debris, wood, rocks, etc., from under the shroud.
Page 37: Start Up
Two Blade Arm, Three Blade Disc & Disc (w/ Cutter Bits) 1) Check the attachment of the Grizzly to the carrier to ensure that all attachment point bolts and pins are in good order. 2) Check all hydraulic lines and connections for leaks and security.
Page 38: Normal Operation
Once the direction of rotation has been determined to be correct and the Control Valve notation indicates the correct direction (in the case of dual direction installations), return the Grizzly to the horizontal position a foot or so above the ground and run it up to speed. It will probably be necessary to increase the engine speed to provide adequate hydraulic pressure/volume to reach maximum shaft speed.
