12.OPERATION 12.8 OPERATION OF WORK EQUIPMENT WARNING If any lever is operated when in the deceleration range, the en- gine speed will suddenly increase, so be careful when operating the levers. The work equipment is operated by the left and right work equipment control levers.
Page 117: Working Mode Selection
12.OPERATION 12.9 WORKING MODE SELECTION WORKING MODE The mode selectro switches can be used to switch the mode to match the conditions and purpose of work, thereby enabling efficient op- eration. Use the following precedures to make the most effective use of each mode.
Page 118 12.OPERATION POWER MAX./SWIFT SLOW-DOWN During operation, power up/speed down of work equipment can be performed by on-touch. Use this function effectively in combination with working mode. When starting switch is turned ON, the power up lamp turns on. When SET switch is pressed once, the speed down lamp turns on and the power up lamp goes out, and when pressed again, the oppo- site occurs.
Page 119: Handling Active Mode
12.OPERATION 12.10 HANDLING ACTIVE MODE Make full use of the active mode to match the purpose and conditions of the opeeration in order to carry out operations effectively and efficiently. The active mode selector switch can be turned ON (lights up) in order to provide quick levelling operations and effective deep digging and load- ing operations.
Page 120 12.OPERATION Turn on the active mode selector switch (lights up). While in this condition, press and hold the knob switch of the left- hand work equipment lever once (single click). Since the machine returns to the normal active mode in 8.5 seconds after the switch is pressed, use the active power-up mode effectively for heavy and quick work.
Page 121: Prohibitions For Operation
12.OPERATION 12.11 PROHIBITIONS FOR OPERATION WARNING • If it is necessary to operate the work equipment control lever when the machine is travelling, stop the machine before oper- ating the work equipment control lever. • If the lever is moved inside the deceleration range, engine speed will suddenly rise.
Page 122 12.OPERATION Prohibited operations using dropping force of machine Do not use the dropping force of the machine for digging Digging rocky ground It is better to excavate hard rocky ground after breaking it up by some other means. This will not only reduce damage to the machine but make for better economy.
Page 123: Precautions For Operation
12.OPERATION 12.12 PRECAUTIONS FOR OPERATION PRECAUTIONS WHEN TRAVELLING When travelling over obstacles such as boulders or tree stumps, the machine (in particular, the undercarriage) is subjected to a large shock, so reduce the travel speed and travel over the obstacle at the center of the tracks.
Page 124: Precautions When Traveling Up Or Down Hills
12.OPERATION 12.OPERATION 12.13 PRECAUTIONS WHEN TRAVELLING UP OF DOWN HILLS WARNING • When travelling, raise the bucket approx. 20 - 30 cm from the ground. Do not travel downhill in reverse • When travelling over ridges or other obstacles, keep work equipment close to the ground and travel slowly.
Page 125 12.OPERATION 12.OPERATION Braking when travelling downhill To brake the machine during downhill runs, put the travel lever in the neutral position. This will cause the brake to be automatically applied. If shoes slip When travelling uphill, if the shoes slip or it is impossible to travel uphill using the force of the track only it is possible to use the pulling force of the arm to help the machine travel uphill.
