Crushing or Cutting Prevention
Make all repairs with the machine parked on a level, hard surface. Block machine so it does not roll while working on or under machine.Do not work on any machine that is supported only by lift jacks or a hoist. Always use blocks or jack stands to support the machine before performing any disassembly. Raise the mainframe (1), pivot support legs (2) to vertical to engage knobs (3), then lower the mainframe onto the support legs before working under the machine.Where there are implement linkages, the clearance in the linkage area will increase or decrease with movement of the implement.Stay clear of all rotating and moving parts.Keep objects away from moving fan blades. They will throw or cut any object or tool that falls or is pushed into them.Do not use a kinked or frayed wire rope cable. Wear gloves when handling the wire rope cable.Retainer pins, when struck with force, can fly out and injure nearby persons.Wear protective glasses when striking a retainer pin, to avoid injury to your eyes.Chips or other debris can fly off objects when struck. Make sure no one can be injured by flying debris before striking any object.To avoid back injury, use a hoist when lifting components which weigh 23 kg (50 lb) or more. Make sure all chains, hooks, slings, etc., are in good condition and are in the correct capacity. Be sure hooks are positioned correctly. Lifting eyes are not to be side loaded during a lifting operation.Burn Prevention
