SAFETY GENERAL PRECAUTIONS WARNING: Failure to follow these safety precautions may lead to a serious accident. When releasing the pressure inside the work equipment circuit on machines equipped with an accumulator, follow the procedure given in the inspection and maintenance section. Method of releasing pressure see “HANDLING THE ACCUMULATOR” on page 101. The accumulator is filled with high-pressure nitrogen gas, and it is extremely dangerous if it is handled in the wrong way. Always observe the following precautions. G Never make any hole in the accumulator or expose it to flame or fire. G Do not weld anything to the accumulator.
G When carrying out disassembly or maintenance of the accu- mulator, or when disposing of the accumulator, it is necessary to release the gas from the accumulator. A special air bleed valve is necessary for this operation, so please contact your Komatsu distributor. Gas in accumulator, see “HANDLING THE ACCUMULA- TOR” on page 101. EMERGENCY EXIT G When exit by normal means is prevented in an emergency you can get out through the emergency exit (rear window). G Pull the ring at the bottom of the window and remove strip. This will allow you to push out glass. ROTATING BEACON (Option) G When the machine is operated on or beside a road, a rotating beacon is required to avoid a traffic accident.
G Contact your Komatsu distributor to install beacon lamp. ELECTROMAGNETIC INTERFERENCE When this machine is operating close to a source of high electro- magnetic interference, such as a radar station, some abnormal phenomena may be observed. G The display on the monitor panel may behave erratically. G The warning buzzer may sound. These effects do not signify a malfunction and the machine will return to normal as soon as the source of interference is removed. 21
