Safety precautions SAFETY PRECAUTIONS GENERAL Maintenance may only be performed by trained personnel or by authorised Konecranes Lifttrucks dealers according to a service contract. If you wish to undertake the maintenance of the machine yourself, we recommend that the first three customer service inspections be carried out in the presence of authorised personnel from Konecranes Lifttrucks who can check that the maintenance instructions are adhered to. PRECAUTIONS WHEN CARRYING OUT ELECTRIC WELDING TAKE CARE It is important that these instructions are adhered to when carrying out electrical welding on the machine, otherwise serious damage can occur. Disconnect the battery cables and all control units. 1. Remove the cables for the batteries and the alternator. 2. Important!Disconnect all control units in and on the machine. 3. Connect the weld clamp to the component that is to be welded and close to the area of the weld, never to the engine or so that the current could run through a bearing. When welding is finished, reconnect the cables to the alternator and the control units before reconnecting the batteries. PRECAUTIONS WHEN JUMP STARTING TAKE CARE Jump-starting the engine using a quick-charger, booster, power pack etc., is prohibited. This can cause a power surge and serious damage to the control units. 1. Connect the first cable from the positive pole on the starter battery to the positive pole on the starter motor. 2. Then connect the other cable from the negative pole on the starter battery to the chassis of the machine, e.g. to the starter motor mounting bolts or a frame member close to the starter motor. 3. When the engine has started: remove the cables in reverse order.

Common electrical systems COMMON ELECTRICAL SYSTEMS THE STRUCTURE OF THE WIRING DIAGRAMS The structure of the wiring diagrams aims to facilitate fault-tracing and service. The different wiring diagrams are divided into circuits with working lights on its own, and heating and ventilation separate etc. This means that when fault-tracing one need only use the wiring diagram that applies to the relevant circuit. Only in a few exceptional cases need one switch to another wiring diagram. If this is necessary there is a grid around the wiring diagram to indicate the correct position. The grid has letters vertically and figures horizontally. CABLE NUMBERING Table 1: Cable function groups Function group number

Power supply Engine Service lights Working lights Windscreen wipers Heating/AC system Cab Transmission control Control (electrical) Machine control systems Mast Unit

Numbering the cables aims to facilitate fault-tracing and service. The five digit cable number is based on the function group to which it belongs. The two first digits indicate the function group and the three last are a serial number within the function group. Each time the cable connects to an active component the three last digits in the cable number change.

WARNING The battery disconnector switch cuts the power from the battery to all electrical functions. However, in some customised machines not all functions are isolated by the battery disconnector switch and may be live.

FUSES The fuses are located on the left under the instrument panel and in the battery box on the right-hand side of the machine.

Replacing connectors CALIBRATING THE TE TRANSMISSION WITH THE APC200 Calibrate the transmission using the APC200. NOTE Two people are needed to carry out calibration. NOTE Check the function of the parking brake! The criteria for calibrating the transmission are: • The parking brake must be activated. • The temperature in the oil sump must be higher than 60°C. The engine speed must be 800 rpm ±200 rpm. 1. Depress the “S” button on the APC200 and start the engine. Continue to hold the S button in until the text “trAn” appears in the V0102 display (this takes about 15 seconds). When this happens release the “S” button. (trAn = transmission ) 2. Press the S button once to select transmission calibration. “Go F” appears in the display. V0107

3. Move the direction of travel selector forward to initiate calibration (on certain 28-32 ton trucks one needs to move the gear selector backwards instead to initiate calibration). Calibration starts and the display shows the various stages of calibration. NOTE To stop calibration: move the direction of travel selector to the backward position. 4. When all gears have been calibrated donE appears in the display; this means that calibration is complete. It normally takes 15 minutes to calibrate the transmission.

V0111

5. Turn off the ignition, wait about 5 seconds and then turn it on again. NOTE Do not turn off the battery disconnector switch immediately after calibration. The calibration values will be lost and calibration will have to be carried out again. 6. When the machine is restarted the APC200 will automatically activate the values from calibration.
