Perkins 1104C-44TAG2 Engine

⚠ Never allow the idle pressure to exceed 8,6 bar on the pressure gauge, otherwise the safety valve will operate.

Tools: adjusting screw

1. Start the machine.
2. Inspect the throttle arm on the engine governor; it should be extended in the full speed position at full-load speed with the service valve fully open.
3. Adjust the service valve to maintain 7 bar (HP95 = 10,3 bar) without the throttle arm moving from full speed.
4. If the throttle arm moves away before the pressure is attained, turn the adjusting screw clockwise to increase pressure.
5. Optimum adjustment is when the throttle arm just moves from full speed position and the pressure gauge reads 7,2 bar (HP95 = 10,5 bar).
6. Close the service valve; the engine will slow to idle speed.

⚠ Check the wheel nut torque 20 miles (30 kilometres) after refitting the wheels.

Tools: adjuster A, nuts B/C/D

1. Ensure the handbrake lever is fully released and the coupling head is fully extended.
2. Adjust each wheel brake in turn while rotating the wheel in the forward towing direction.
3. Adjust the brakes until they lock-up using adjuster A.
4. Release adjuster A until only a slight resistance is felt during wheel rotation.
5. Adjust nuts B and lock with the equaliser C parallel to the axle.
6. Take up play with nut D behind the equaliser without pre-loading the brakes; ensure all locknuts are secured.
7. Check overrun lever play E and spring free length F.

⚠ Never remove or replace switches when the machine is running.

1. At three month intervals, start the machine.
2. Connect a wire between the switch terminal and a suitable earth point; the machine should shutdown.
3. Do not press the load button.
4. At twelve month intervals, remove the switch from the machine.
5. Connect it to an independent low pressure supply (air or oil); the switch should operate at 1,0 bar.
6. Replace the switch.

⚠ Never remove or replace switches when the machine is running.

1. At three month intervals, start the machine.
2. Disconnect each temperature switch in turn; the machine should shutdown.
3. Re-connect the switch. Do not press the load button.
4. At twelve month intervals, remove the high discharge air temperature switch and immerse it in a bath of heated oil; it should operate at 120C. Replace the switch.
5. Remove the high oil temperature switch and immerse it in a bath of heated oil; it should operate at 130C. Replace the switch.

⚠ Never remove and replace element(s) when the machine is running.

⚠ NEVER clean by blowing air inwards.

1. Never remove or replace element(s) when the machine is running.
2. Clean the exterior of the filter housing and remove the element by releasing the nut.
3. Check for cracks, holes or other damage by holding the element to a light source or passing a lamp inside.
4. Check the end seal and replace the element if any damage is evident.
5. Assemble the new element ensuring the seal seats properly.
6. Secure the element by hand tightening the nut.
7. Reset the restriction indicator by depressing the rubber diaphragm.
8. Assemble the dust collector box parts correctly and check all clamps are tight.

⚠ Always disconnect the battery cables before performing any maintenance or service.

1. Disconnect the battery cables before performing any maintenance or service.
2. Keep battery terminals and cable clamps clean and lightly coated with petroleum jelly.
3. Keep the retaining clamp tight enough to prevent the battery from moving.

⚠ Do not remove the filter without first making sure the machine is stopped and the system has been completely relieved of all air pressure.

1. Stop the machine and ensure the system is completely relieved of air pressure.
2. Clean the exterior of the filter housing.
3. Remove the spin-on element by turning it counter-clockwise.
4. Examine the element; varnish, shellac or lacquer indicates oil deterioration and immediate oil change.
5. Clean the filter gasket contact area.
6. Install the new element by screwing clockwise until the gasket contacts the housing.
7. Tighten a further 1/2 to 3/4 of a revolution.
8. Start the machine and check for leakage before returning to service.

⚠ Do not remove the staple from the anti-static gasket; it grounds possible static build-up.

⚠ Do not use gasket sealant; it affects electrical conductance.

1. Stop the machine and ensure the system is completely relieved of air pressure.
2. Disconnect all hoses and tubes from the separator tank cover plate.
3. Remove the drop-tube from the cover plate, then remove the cover plate and separator element.
4. Examine the element and all hoses/tubes; replace if necessary.
5. Thoroughly clean the orifice/drop tube and filter gasket contact area.
6. Install the new element; do not remove the staple from the anti-static gasket and do not use gasket sealant.
7. Reposition the cover plate carefully and tighten screws in a criss-cross pattern to the recommended torque.
8. Replace the drop-tube and reconnect all hoses and tubes.
9. Replace the compressor oil.
10. Start the machine and check for leakage before returning to service.

1. Turn the key switch located on the instrument panel to the 0 (off) position.
2. For generator operation, use the second control at the socket control panel to immediately isolate all electrical power to all sockets, then use the key control to stop the engine.

⚠ Do not start or stop the machine with the compressor/generator mode switch in the Generator position.

⚠ Do not operate the machine unless it has been suitably earthed.

1. Ensure compressor/generator mode switch is set to compressor before starting.
2. Do not start or stop the machine with the compressor/generator mode switch in the Generator position.
3. When the switch is in Generator position, the normally-open solenoid valve closes and the engine maintains maximum speed.
4. Connect electrical equipment with the appropriate MCB in the OFF position.
5. Switch the MCB to ON immediately before using the equipment.
6. For emergency, use the socket panel control to isolate all electrical power to all sockets, then use key control to stop engine.

⚠ Do not overfill either the engine or the compressor with oil.

⚠ Use only No. 2-D diesel fuel oil with minimum octane number 45 and sulphur content not greater than 0,5%.

1. Place the unit as level as possible; design permits a 15 degree lengthways and sideways limit on out-of-level operation.
2. Check engine lubrication oil in accordance with the Engine Operator's Manual.
3. Check compressor oil level in the sight glass on the separator tank.
4. Check diesel fuel level; top up at the end of each working day to prevent condensation.
5. Drain the fuel filter water separator of water, containing released fuel safely.
6. Open service valve(s) to relieve all pressure, then close them.
7. Check the air restriction indicator(s).
8. In temperatures near or below 0C, ensure regulation system, unloader valve, safety valve and engine are not impaired by ice or snow; keep inlet/outlet clear.

⚠ Under no circumstances should volatile liquids such as Ether be used for starting this machine.

1. Turn the key switch to position 1; the alternator charge light will illuminate.
2. Turn the key switch to position 3 (engine start position).
3. Release to position 2 when the engine starts.
4. Release to position 1 when the alternator charge light is extinguished.
5. At temperatures below 0C or if starting is difficult: open the service valve fully with no hose connected.
6. Complete the starting sequence above.
7. Close the service valve as soon as the engine runs freely.
8. Do not allow the machine to run for long periods with the service valve open.
9. Allow the engine to reach operating temperature before applying full load.
