Komatsu — PRECAUTION WHEN USING ABS SYSTEM

. ATTACHMENTS, OPTIONS HANDLING ANTI SKID BRAKE SYSTEM (ABS) OPERATION OF ABS The ABS system can be actuated when the ABS switch is turned ON. PRECAUTION WHEN USING ABS SYSTEM WARNING the secondary brake function is maintained, but when the secondary 6 - 20 The ABS system automatically control s slipping caused by locking of the wheels, and sh ortens the braking distance. Use the ABS system when traveling o When the tires tend to lock, if the retard er control lever is operated, or the brake pedal is depressed, the AB S system is actuated. When this happens, the A BS actuation lamp lights up.

If t he accelerator pedal is depressed, Even if the ABS system is used, the stopp ing distance on wet road surfaces is longer than the stopping distance o n dry road surfaces. Reduce the travel speed when tr aveling on wet surfaces to reduce the stopping distanc e. If any mistake is made i n the stopping distance, it may lead to serious p ersonal injury. When traveling on roads with an ex tremely low friction coefficient (icy roads, etc.) o r when traveling u p or d own a steep hill, it may not be possible t o ensure safe travel even with the ABS installed . In such cases, carry out maintenan ce on the road surface before traveling on it.

The ABS is not actuated when the r etarder control lever or brake pedal are operate After turning the ABS main switch O N, it takes a short time for the preparation of the ABS operation, s o the ABS is not actuated for 2 seconds. Turn the ABS main switch ON beforehand if it is to b e actuated. It is possible to carry out normal tra vel even when the ABS main switch is OFF. Ho wever, be extrem ely careful about the machine slipping to the si Even if there is a failure in the ABS s ystem, it is possible to carry out normal travel. Ho wever, be extrem ely careful about the machine slipping to the sid e when traveling on slippery road surfaces.

If an y problem occurs i n the ABS system, the system is automatically canceled, display the action code on charactor display. When AB S system canceled, so the condition become the same as for a machine which does not have the ABS installe d. brake is actuated, even if the wheel When equipping the machine with a wireless system, install it as for as possible from the system equipmen t and wiring. In addition, when equipping the mac hine with a wireless system, check carefully tha t the wireless and operating system do not break any laws regul ating use of the airwaves.
