SAFE OPERATION -1 SAFE OPERATION Careful operation is your best insurance against an accident. Read and understand this section carefully before operation. All operators, no matter how experienced they may be, should read this and other related manuals before operation of the machine or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation. This cutting machine is capable of amputating hands and feet and throwing objects.
-2 SAFE OPERATION 19. Do not operate where machine could tip or slip. Do not operate near ditches, holes, embankments, or other terrain which may collapse under the machine's weight. The risk of machine tip-over is increased when the ground is loose or wet. C Pulling loads Use extra care when pulling loads to reduce the risk of serious personal injury or death due to a machine tip-over. a) Pull only from the hitch. Never attach loads to the axle housing or any other point above hitch.
SAFE OPERATION 9. If the machine stops going uphill, disengage PTO and back slowly down. 10. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tip-over or loss of control. 11. Use special caution when changing direction on slopes. DO NOT 1. Do not turn on slopes unless necessary and then turn slowly and gradually downhill, if possible. 2. Do not mow near drop-offs, ditches, or embankments.
-4 SAFE OPERATION 11. Do not smoke when working around the battery. Keep all sparks and flames away from battery. The battery presents an explosion hazard because it gives off hydrogen and oxygen...especially when recharging. 12. Before "JUMP STARTING" a dead battery, read and follow all of the instructions to help protect the alternator from damage due to extreme load changes. (See "JUMP STARTING" in "OPERATING THE ENGINE" section.) Batteries contain sulfuric acid and produce explosive gases.
