Bryant Liquid-cooled 25 kW Generator

‹4.8.5 CHECK ENGINE COOLANT LEVEL

See “Checking Fluid Levels”.

‹4.8.6 PERFORM VISUAL INSPECTION

Complete a thorough visual inspection of the entire engine-generator monthly. Look for obvious damage, loose, missing or corroded nuts, bolts and other fas- teners. Look for fuel, oil or coolant leaks.

4.Turn OIL FILTER (Figure 4.1) counterclockwise and remove. Properly dispose of old filter.

5.Apply light coating of new engine oil to seal of new oil filter. Install FILTER and tighten by hand only.

DO NOT OVER TIGHTEN.

6.Remove OIL FILL CAP. Add recommended oil (see

SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK “FULL” MARK. Crankcase oil capacity is 4.0 U.S. quarts (3.8 liters).

‹4.8.7 INSPECT EXHAUST SYSTEM

Inspect the exhaust system at least once every three months. Check all exhaust system pipes, mufflers, clamps, etc. for condition, tightness, leaks, security, damage.

‹4.8.8 CHECK FAN BELT

•Inspect fan belts every three months. Replace any damaged, deteriorated, worn or otherwise defec- tive belt.

•Check fan belt tension. Thumb pressure, exerted midway between pulleys, should deflect about 3/8 to 5/8 of an inch. Adjust belt tension as required.

‹4.8.9 INSPECT ENGINE GOVERNOR

Visually inspect electronic governor.

DANGER

DANGER: Do not attempt to adjust the gover-

!nor. Only qualified service facilities should adjust the governor. Excessively high operating speeds are dangerous and increase the risk of personal injury. Low speeds impose a heavy load on the engine when adequate engine power is not available and may shorten engine life. Correct rated frequency and voltage are supplied only at the proper governed speed. Some connected electrical load devices may be damaged by incorrect frequency and/or volt- age. Only qualified service technicians should adjust the governed speed.

‹4.8.10 CHANGING ENGINE OIL

Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies.

Drain the oil while the engine is still warm from run- ning. This means warm up the engine, shut it down and drain immediately as follows:

1.Remove OIL DRAIN HOSE from its retaining clip.

2.Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container.

3.When all oil has drained, install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip.

After refilling the crankcase with oil, always

!check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIPSTICK “ADD” MARK.

7.Start engine and check for oil leaks.

‹4.8.11 CHANGING THE ENGINE AIR CLEANER

To replace the engine air cleaner, (part number 059402), simply remove the air cleaner cover and replace the air filter making sure it is positioned properly before reattaching the cover (Figure 4.1).

See the “Service Schedule,” for air cleaner mainte- nance (Section 4.10).

‹4.8.12 SPARK PLUGS

Reset the spark plug gap or replace the spark plugs as necessary (Figure 4.4).

1.Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and com- mercial solvent. Do not blast the spark plugs to clean.

2.Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule,” Section 6, for recommended inspection.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 1.07-1.17 mm (0.042- 0.046 inch) by carefully bending the ground elec- trode (Figure 4.2).
