8. After replacing the filter cartidge, add engine oil through oil filter F until the oil level is between the H and L marks on dipstick G. For details of the oil to use, see ”20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”. 9. Run the engine at idling for a short time, then stop the engine, and check that the oil level is between the H and L marks on the dipstick. For details, see ”24.3 CHECK BEFORE STARTING”. Even if the machine has not been operated for 250 hours, the oil and filter cartridge must be replaced when the machine has been operated for 6 months.
In the same way, even if the machine has not been operated for 6 months, the oil and filter cartridge must be replaced when the machine has been operated for 250 hours. 24.5.11 REPLACE CORROSION RESISTOR CAR- TRIDGE 1. Screw in valves a at the top of the corrosion resistor. 2. Using a filter wrench, turn cartridge b to the left to remove it. 3. Coat the seal surface of the new filter cartridge with engine oil, then install it. When installing, bring the packing surface into contact with the seal surface of the filter holder, then tighten a further 2/3 turn. 4. Open valve a . 5. Run the engine and check that there is no leakage of water from the seal surface.
Anti-freeze alone is not sufficient to prevent corrosion within the en- gines fitted to these machines. Additional corrosion protection is pro- vided with supplemental coolant additive. This is supplied in the cor- rosion resistor fitted to the engine, this supplies a dosage of the chemical DCA4 into the engine coolant. To ensure the correct dosage of DCA4, the collant should be tested and an appropriate dosage corrosian resistor fitted. Use the DCA4 test kit (Part No. 6742-01-4130) to determine the cur- rent dosage of DCA4 in the engine coolant. Follow the instructions included in the kit.
a) If the concentration is below 0.3 units/litre replace the service filter with corrosion resistor (Part No. 6742-01-4110). b) If the concentration is between 0.3 units/litre and 0.8 units/litre re- place the service filter with corrosion resistor. c) If the concentration is greater than 0.8 units/litre do not replace the filter. Monitor the concentration at next service. Do not use the kit extend or omit the service intervals unless the con- centration is greater than 0.8 units/litre. Important: Serious engine damage can occur during prolonged usage with an under or over dosed system. PC450-ENG 3-62
