FELLING TREES
Pieces of wood, debris from the ground and even teeth separating from the saw blade become potentially dangerous missiles when thrown from these machines. Inspect saw teeth, tooth retaining bolts, saw disc and felling head assembly. Ensure that all saw tooth retaining bolts are at correct torque value. Refer to attachment manual for correct values. Replace all worn saw teeth or rotate worn teeth to align unused cutting tips. Always replace saw tooth retaining bolts when replacing saw teeth. Inspect saw disc for stress cracks and that saw disc does not wobble due to worn saw shaft bearings. Never start the machine if saw blade has missing teeth, teeth retaining bolts or a bent saw disc. Shut down machine immediately if vibration occurs during cutting. Check that the saw discharge area is clear and undamaged. When moving from tree to tree with the saw blade turning, take care not to make contact with other vegetation or debris. Do not over load felling head. Work within your operating skills, do not attempt to cut down a tree that is too large for the felling head. Operate so that the chip discharge area of the felling head (where applicable) is not directed at people, livestock, buildings or other machines. When cutting, properly position felling head in front of tree and have saw blade running at full rpm. Always know and control the direction the tree will fall to prevent injury to co-workers or damage other vehicles. When backing away from a cut, watch out for obstacles in your path. Always travel with felling head as close to the ground as possible, never elevate the felling head unless necessary. Never use this machine to clear a logging deck on a new tract of timber when the rest of the equipment and operator's are also moving in. Preplan to clear decks in advance before other equipment arrives. Never work alone. Regularly inform other crew members of your intentions, location and length of time to perform duties. Stop the saw blade before leaving the cutting area. NOTE: The saw blade will continue to free wheel for several minutes after the saw switch has been turned OFF. To stop the blade from rotating, CAREFULLY lower the saw blade onto a stump gently to prevent unnecessary loading of the saw blade, saw housing and bearings.
