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 acci- dents.
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 155: Buzzbar Head
MAINTENANCE Buzzbar Head BLADES For best performance, have blades set and sharpened when they begin to dull. Blades can be touched up with a grinder or file between sharpenings. To extend the life of the blade, remove resin accumulations. When the resin builds up, the blades will "burn" in the cut, causing the blades to overhea t and warp.
Page 156 MAINTENANCE Belt Tension Adjustment (Figure Mnt-B-0010) Loosen nuts on the 4 studs and the jam nut. Use a hand wrench or socket to tension the belts. Never use power or air equipment to tighten belt! This could cause damage to belt, sheave, shaft and bearings Once the belts begin to tighten, small adjustments will produce large changes in tension.
Page 157 MAINTENANCE Lubrication: Grease each spindle with on e pu mp of high qua lity lithium grease weekly . More th an o ne pu mp is unnecessary and will cause a mess when extra grease squirts out of the relief. Grease fittings are on front of machine, just above the blades.

A properly operated Flail Mower will produce very little vibration. If vibration does occur, the mower should be stopped and the trouble corrected, as warranty does not cover failures resulting from continued operation after something happens to cause the mower to vibrate excessively.
