Reserve strength is built into the fully welded structures for hydraulic hammer and other arduous operations. Fabricated bucket tipping links are provided with a choice of lift points. CAB AMS ADVANCED MANAGEMENT SYSTEM Excellent digging, loading and positioning visibility results from the careful design of front, side and roof lights. All screens are tinted to improve in cab conditions. Fully opening front windshield is very smooth to operate and as the lower windshield is stored within the top screen frame it makes complete front screen opening easy, fast and convenient. Fresh air ventilation available from opening door window, opening slot in front windshield and fully opening front windshield. Parallelogram wash wiper for upper windshield ensuring good wiped area for maximum visibility. Wiper motor is fitted in the left hand side of the roof light so as not to affect bucket visibility when loading. Optional lower wiper available. Fresh air ventilation and heater with windshield demister. Infinitely variable blower speed, temperature and recirculation control. Air conditioning incorporating chilled cool box available as option. Fully adjustable deluxe suspension seat with arm rest adjustment and backrest recline. Radio cassette player with digital tuner fitted into the roof lining for maximum protection. Conveniently placed radio mute button incorporated into lower console. 12v power point and mobile phone holder built into the right hand console. Courtesy light can be operated from ground level and is illuminated for five minutes or until switched off improving operator access at night. Cab mounted roller blind protects operator from suns glare through front or top screens. Four selectable working modes link the operators control movements with the engine and hydraulic systems to maximise productivity and efficiency. A (Auto) Up to 1% engine power and 1% flow. Gives variable power and speed depending on the operator s input, matching the demand for output and efficiency to the job. Power boost is automatically activated in this mode should hard conditions be encountered. Auto idle cuts in after a period of inactivity (between 5 and seconds as set by the operator) E (Economy) % engine power. 95% of hydraulic flow maximises economy while maintaining excellent output. P (Precision) 55% engine power. 9% of hydraulic flow for fine control of grading operations. L (Lifting) 55% engine power. % of hydraulic flow with permanent power boost for maximum lifting power and control. The Auto mode allows the AMS processor to select the optimum operational performance to match the demands of the job while the three alternative modes give precise matching of application when specific tasks are undertaken. The adjustable position monitor mounted on the front right hand pillar of the cab gives the operator a constant read out of mode, tracking range, operating temperature and a host of other information, while retaining excellent visibility of the monitor and the job being carried out. The required flow for hammer applications can be set and stored in the AMS memory and is automatically activated whenever the hammer pedal is depressed.a maintenance indicator warns of imminent service needs, and all servicing and basic checks can be carried out using only the in cab display.
