Common problems

Use or operate the engine on or near any forest-covered, brush-covered land, or grass-covered land.
Fix: The exhaust system must be equipped with a working spark arrester meeting state laws.
Touch the terminals and sockets while the machine is running.
Fix: Avoid electric shock hazard: Do not touch the terminals and sockets while the machine is running.
Touch the machine with wet hands.
Fix: Avoid electric shock hazard: Do not touch the machine with wet hands.
Check and service the machine while it is running.
Fix: Avoid electric shock and injury hazard: Do not check and service the machine while it is running.
Battery fluid level stands below the LOWER mark.
Fix: Immediately, add distilled water until the fluid level is between the UPPER and LOWER levels. (for only refillable battery)
Use machine in poorly-ventilated place
Fix: To avoid exhaust gas poisoning hazard, do not use the machine indoors or in tunnels.
Touch terminals and sockets while running
Fix: To avoid electric shock hazard, do not touch the terminals and sockets while the machine is running.
Touch machine with wet hands
Fix: To avoid electric shock, do not touch the machine with wet hands.
Generator does not start or runs poorly.
Cause: Faulty spark plug, dirty air filter, clogged fuel line, low fuel level, faulty ignition system, or incorrect engine oil level.
Fix: Check and replace the spark plug if necessary. Clean or replace the air filter. Clear any blockages in the fuel line. Refuel with fresh fuel. Check and adjust the ignition system as needed. Ensure the correct amount of engine oil is present.
Direct exhaust to people and buildings
Fix: To avoid exhaust gas poisoning and fire hazard, do not direct the exhaust to people and buildings.
Check and service machine while running
Fix: To avoid electric shock and injury hazard, do not check and service the machine while it is running.
Battery fluid level below LOWER mark
Fix: To avoid component deterioration and potential explosion, add distilled water until the fluid level is between UPPER and LOWER marks.
UNDERVOLTAGE 13
Fix: Reduce the number of connected appliances, especially when air conditioners and battery chargers are running.
UNDERFREQUENCY—Engine governor unable to maintain rated frequency CODE NO. 15
Fix: 1. Reduce the number of appliances running at the same time, especially those with high motor starting loads such as air conditioners. 2. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8).
Underfrequency 15
Fix: Check engine speed, loads, governor actuator operation, fuel supply, control plugs fully seated, quad leads fully seated in connector to control, quad winding resistance

Remove access cover on left end of genset.
Find leads marked J8 HZ, 60 HZ and 50 HZ in wiring harness.
Connect 60 HZ or 50 HZ lead to J8 HZ as appropriate.
Secure access cover with four screws.

Adjusting High-Idle Speed adjustment

⚠ Keep your hands away from the engine belt and pulleys.

⚠ The actuator could overheat if the battery is left on more than 10 minutes.

⚠ Be prepared to clamp off supply and return fuel lines to stop the engine.

Tools: strobe or injector clamp-on tachometer, 12 volt battery, battery switch

Adjust the speed control lever stop.
Measure engine speed with a strobe or injector clamp-on type tachometer.
Remove the front and top access doors and loosen the front/left side panel assembly for access to the speed adjusting screw.
Disconnect the actuator leads and connect a 12 volt battery to the actuator terminals using a battery switch.
Switch the battery on, start the genset, measure engine speed (rpm) and stop the engine by switching off the battery.
Loosen the lock nuts on the two bottom screws and back out the clamping screw if speed is not between 3300 and 3400 rpm.
To increase speed turn the speed adjusting screw in 1 turn clockwise; to decrease turn it out 1 turn counterclockwise.
Repeat until high-idle speed is between 3300 and 3400 rpm and set the lock nut.
Run the clamping screw in by hand until snug, back it out 1-1/2 turns and set the lock nut.

Adjusting Speed Control Lever Stop adjustment

⚠ Accidental or remote starting can cause severe personal injury; disconnect the negative battery cable.

Remove the front and top access doors and loosen the front/left side panel assembly so it can swing left.
Loosen the stop screw locknut and back the screw out a few turns.
Turn the stop screw in until it just makes contact and set the locknut.

Adjusting V-Belt Tension adjustment

⚠ Accidental or remote starting can cause severe personal injury or death.

Disconnect the negative cable at the battery.
Remove the belt guard or enclosure top panel and access doors.
Loosen the alternator pivot bolt first, then the adjusting bracket bolt on top.
Pivot the alternator out to tighten belt tension.
Check tension by applying 20 pounds (10 kg) to the middle of the pulley span.
Tighten alternator bolts when deflection is 3/8 inch (10 mm), secure guard and reconnect cables, negative last.

Adjusting Valve Clearance adjustment

⚠ Valve clearance must be checked and adjusted when engine is cold.

Tools: Feeler gauge

Remove the head cover, the glow plugs and the timing window cover.
Align the 1TC mark line on the flywheel with center of timing window for No. 1 piston.
Check valve clearance with a feeler gauge.
Adjust with the adjusting screw if not within factory specification.
Turn flywheel 6.28 rad (360°) and adjust all other valve clearances.
Recheck clearance and firmly tighten the lock nut.

Adjusting Valve Lash adjustment

⚠ Do not use the fuel injection timing marks when adjusting valve lash.

Rotate the engine clockwise (looking from the front) until the intake valve push rod just stops moving down (valve closed).
Turn the engine one half turn more.
Adjust lash for both intake and exhaust valves of that cylinder.
Repeat this procedure for the other cylinder.
