1. Air cylinder adjustment
(1)With the load lever in the idle position, temporarily set the distance between the load lever A and the air cylinder D at approximately L.
(2)Set N1 and apply P1 to the air cylinder D.
(3)Adjust set bolt (D) to obtain R1 at the same speed.
(4)Lock using nut C.
(5)Apply positive pressure several times.
(6)Confirm that the load lever A returns to the idling position N2 at pressure P2.
(7)Also at P1 confirm R1 (N1).

Information:
Coolant
At operating temperature, the engine coolant is hot and under pressure. The cooling system and all lines to heaters or the engine contain hot liquid. When pressure is relieved rapidly, this hot liquid can turn into steam.Allow cooling system components to cool before draining. Any contact with hot liquid or steam can cause severe burns. Check the coolant level only after the engine has been stopped and the vent release valve is cool enough to remove with your bare hand.Remove the cooling system vent release valve slowly to relieve pressure. Use caution when removing vent release valve, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.Cooling system additive (conditioner) contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.Keep all exhaust manifold and turbocharger shields in place to protect hot exhaust from oil spray in the event of a line, tube or seal failure.Batteries
Always wear protective glasses when working with batteries. Battery electrolyte contains acid and can cause injury. Avoid contact with the skin and eyes.Wash hands after touching batteries and connectors. Use of gloves is recommended.Do not smoke when observing the battery electrolyte levels. Batteries give off flammable fumes which can explode. Ensure there is proper ventilation for batteries which are located in an enclosure.Never disconnect any charging unit circuit or battery circuit cable from the battery when charging unit is operating. A spark can cause the flammable vapor mixture of hydrogen and oxygen to explode.Fire or Explosion Prevention
Fire may result from lubricating oil or fuel sprayed on hot surfaces causing personal injury and property damage. Inspect all lines and tubes for wear or deterioration. They must be routed, supported or clamped securely. Tighten all connections to the recommended torque. Leaks can cause fires.Determine whether the engine will be operated in an environment in which combustible gases could be drawn through the air inlet system. These gases could cause the engine to overspeed, which in turn could seriously damage the engine and result in bodily injury or property damage.If your application involves the presence of combustible gases, consult your Caterpillar dealer to obtain additional information concerning protection devices suitable for the application involved.All fuels, most lubricants and some coolant mixtures are flammable. Diesel fuel is flammable. Gasoline is flammable. The mixture of diesel and gasoline fumes are extremely explosive.Do not smoke while refueling or in a refueling area.Do not smoke in areas where batteries are charged, or where flammable materials are stored.Always thaw a frozen battery before jump starting. Frozen batteries may explode. Batteries give off flammable fumes which can explode.Keep all fuels and lubricants stored in properly marked containers and away from all unauthorized persons.Store all oily rags or other flammable material in a protective container, in a safe place.Do not weld or flame
