0000001801 POTENTIOMETER ADJUSTMENT

Adjustment of the potentiometer
Adjustment method (supply voltage Vi, dummy bolt method)
1. Hold the dummy bolt (A) against the control lever at position N = N1 and Q = Q1 and fix using the lock nut.
2. When adjusting the potentiometer, position the control lever against the dummy bolt (A) and adjust so that the output voltage is V1.
3. After adjustment, remove the dummy bolt and confirm that the potentiometer output voltage at the control lever's idling and full positions is as specified in the table.

0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust using screw (A) so that the timer stroke is the value determined using the graph (M). [(K), (M)]
2. Adjustment of the position of the intermediate lever.
Insert the shim (L1) between the control lever (I) and the idle set screw (G).
Align the intermediate lever (F) with the aligning mark (J) and fix the intermediate lever screw (E) so that it contacts the control lever. [(K), (L)]
3. Adjustment of the FICD
Insert the shim (L2) between the control lever (I) and the idle set screw (G).
Fix with the adjusting screw to the position where the CSD lever (C) actuates the intermediate lever through the rod (D). (K), (L), (M)
(O) timer stroke adjustment (mm) - (1): TA = -0.0235t + 1.17
(P) Lever angle (deg) - (2): Theta 1 = -0.0625 t + 5.65 (-20 deg C <= t <= 20 deg C)
Theta 2 = -0.1108t + 6.62 (20 deg C =< t =< 60 deg C)
(Q) lever position (mm) - (3): L1 = -0.02075t + 1.878 (-20 deg C <= t <= 20 deg C)
L2 = -0.03900t + 2.277 (20 deg C =< t =< 60 deg C)
The (Q) indicates the clearance between the control lever and the idle set screw.

Information:
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
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.Batteries give off flammable fumes which can explode. Ensure there is proper ventilation for batteries which are located in an enclosure.Always thaw a frozen battery before jump starting. Frozen batteries can explode.Do not smoke when observing battery electrolyte levels.Always wear protective glasses when working with batteries.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 (i.e. air inlet shutoff) 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 is 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.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 cut on pipes or tubes that contain flammable fluids. Clean them thoroughly with nonflammable solvent before welding or flame cutting on them.Remove all flammable materials such as fuel, oil and other debris before they accumulate on the engine.Do not expose the engine to flames, burning brush, etc., if at all possible.Shields (if equipped), which protect hot exhaust components from oil or fuel spray in the event of a line, tube or seal failure, must be installed correctly.Provide adequate and proper waste oil disposal. Oil and fuel filters must be properly installed and housing covers tightened to proper torque when being changed.Batteries must be kept clean, covers kept on all cells, recommended cables and connections used and battery box covers kept in place when operating.When starting from an external source, always connect the positive (+) jumper cable to the POSITIVE (+) terminal of the
