Clark Forklift C20L

• Every 1000 operational hours, or once annually, the filter elememts in the liquid gas preliminary filter and in the shut-off valve must be renewed, as well as diaphragms, seals and valves.

• After each maintenance, the cap screws of the evaporator pressure regulator must be tightened with a torque of 4.1±0.3 Nm.

• Check the LPG system after every repair or service to make sure that it is free of leaks.

Engine air cleaner • Check the engine air cleaner for damage and contamination (excessive dirt buildup and clogging). Be sure that the air cleaner hose is securely connected (not loose or leaking). Fan or cone shaped dust deposits on tube or hose surfaces indicate a leak.

• Change or service the air cleaner element every 2000 operating hours for LPG/Gas engine, every 1000 operating hours for Diesel engine depending upon your application.

• Service intervals may also be determined by the air restriction indicator.

• Clean the air filter housing thoroughly before fitting the filter.

• Do not open the air filter housing to check the filter element.

1. Close the shut-off valve of the LPG tank to be changed by turning the valve as far as possible clockwise. Let the engine run until it stops of its own accord. By doing this you will avoid the risk of liquefied gas spraying out from the hose (danger of frostbite) when you loosen the union.

3. Separate the hose from the LPG tank (left hand thread). Close the connection on the LPG-tank with the cap nut.

4. Slacken the strap holding the LPG tank and take away the empty LPG tank.

5. Replace the empty LPG tank with a full one. Check that the unions at the end of the hose and on the LPG tank are of the same type. Take care that you place the LPG tank in the correct position. The union for the hose must face downwards.

6. Secure the LPG tank strap and connect the hose.

7. Open the shut-off valve of the LPG tank slowly by turning it anticlockwise as far as it will go. Check the LPG system for tightness.
