SAFETY WORKING
• Do not work on the machine while under the influence of alcohol, medication, or other substances or while fatigued.
• Wear close fitting clothing and safety equipment appropriate to the job.
• Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended.
• When servicing is performed together by two or more persons, take care to perform all work safely.
• Do not touch the rotating or hot parts while the engine is running.
• Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spout out from radiator. Only remove radiator cap when cool enough to touch with bare hands. Slowly loosen the cap to first stop to relieve pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure.
• Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises.
