Komatsu — GENERAL MACHINE PRECAUTIONS

SAFETY PRECAUTIONS Avoid parking on a slope because unexpected machine movement may occur. If necessary to park on a slope, park at right angle to the slope and block the tires. Always lock the machine, including any anti-vandalism attachments, when leaving it unattended. MAINTENANCE GENERAL MACHINE PRECAUTIONS Constantly be aware of dangers involved in working on the machine and take proper precautions. It is not possible to anticipate all conceivable ways or conditions under which this machine may be serviced or to provide precautions for all the possible hazards that may result. Safety is always the most important rule.

Standard and accepted safety precautions and equipment should be used. Do not attempt repairs you do not understand. Consult your Distributor for information and service. NEVER run the engine when cleaning or lubricating the machine because serious injury could result from contacting moving parts. Before servicing the machine, BE SURE the engine is off, the bucket is lowered, the transmission directional lever is in neutral (N), the parking brake is applied and the electrical starting switch is off and the key is removed. Tag the machine. Before working on the engine or electrical system, disconnect the negative (ground) battery cable. Tag the cable and controls to warn against starting.

Before working under the machine, block the tires to prevent machine movement. ALWAYS lock the front and rear frames together with the safety bar and pins before working near the center of the machine. If the frames move, serious injury could result. NEVER stand near the bucket or the tires while the engine is running. During servicing, DO NOT allow anyone in the operator’s compartment who is not trained and assisting in the servicing. When it is necessary to make any checks or adjustments with the engine running, use two people. A trained operator must be at the controls to safeguard the mechanic making the checks or adjustments.

BE SURE the transmission directional lever is in neutral (N), the parking brake is applied and the front and rear frames are locked together. Be sure the engine hood or access door(s) is secure in the open position during service work in the engine compartment. Unexpected closing could cause injury. NEVER remove any guards or shields with the engine running because of the danger of contacting rotating parts. When service requires access to areas that cannot be reached from the ground or a service platform on the machine, use a ladder or platform of appropriate capacity. Use only approved parts for repairs and maintenance.

Failure to do so could compromise personal safety, machine performance and reliability. l-8
