  • Page 45 The first inspection of the truck diesel engine must be carried out by a regional DAF-dealer. At the inspection the DAF-dealer is to fill out the warranty form supplied by Spierings. For this inspection the DAF-dealer will only bill you for the costs of oil and filters.
  • Page 46 This inspection should preferable be carried out by service staff of Spierings Kranen. The truck diesel engine gets a full maintenance, and the oil in the complete truck drive line is changed. For this purpose Spierings Kranen uses synthetic oil (75W90). This oil does not need changing in all drive line components for two years. The hydraulic filter is replaced.
  • Page 47 Unscrew the red cap on the filling pipe (1). Always top up engine oil of the same brand and type. (In doubt please always consult Spierings Cranes.) Check the oil level with the dipstick. (4.3.1 Check the engine oil level) Picture 4-4 AT6-EN-061031.doc...
  • Page 48 MANUAL SPIERINGS TRUCK AT6 4.3.3. Change engine oil Change engine oil after every 15,000km or at least once a year and during the annual maintenance. Make sure the truck stands on level ground. Preferably run the engine till it is at operating temperature and then switch it off.

  • Page 71 D) Hydraulic auxiliary cylinders E) Emergency cylinder The AT6 steering system steers axles 1, 2, 3, 5 and 6, whereas axles 5 and 6 are steered in opposite direction, to create a smaller turning circle. Picture 6-1 shows how the steering is constructed. The steering can be divided in two parts; the three front axles and the two rear axles.
  • Page 72 To prevent excessive tyre wear the truck must be aligned every year. Before the crane is aligned, the play in steering arms and steering rods must be checked. As the crane is fitted with an electronic rear axle steering, we recommend that you contact Spierings Kranen before you start the alignment.
  • Page 73 MANUAL SPIERINGS TRUCK AT6 7. Electrical system The on-board power on the truck is 24V, provided by two 12V/165Ah batteries series connected. During operation these batteries are charged by a 24V dynamo with a maximum charging current of 35A. With the battery switch in the truck cab the truck's electrical system can be cut off. Use this switch in case of welding on the crane or when the crane is parked for a longer period of time.

  • Page 77 MANUAL SPIERINGS TRUCK AT6 8.2. Changing hydraulic oil Change the hydraulic oil every 5 years after oil analysis. Before changing the oil first an oil sample is analysed. If it is necessary to change the oil, all hydraulic cylinders must be retracted, including the suspension cylinders.
  • Page 78 MANUAL SPIERINGS TRUCK AT6 8.3. Replace hydraulic oil filter Replace the hydraulic oil filters during the annual maintenance under normal operating conditions. 8.3.1. Hydraulic fine filter Picture 8-3 The hydraulic fine filter (1) is located under the left-hand engine cowling (Picture 8-3) To reach it, the upper plate must be removed after the tower has been put in upright position.
  • Page 79 Under normal operating conditions check de suspension accumulators every year. The AT6 suspension has 12 accumulators. They are all mounted on the hydraulic suspension cylinders on each axle. To check the accumulators you need special tools from HYDAC. The pressure must be 110 bar.
  • Page 80 MANUAL SPIERINGS TRUCK AT6 8.5. Hoses and couplings hydraulic system Check all components of the hydraulic system for leaks and damage every two months. All hoses, couplings, hydraulic blocks, filters, cylinders and the oil tank have to be checked regularly for damage and leaks.
