Engine Coolant; Maintenance Owner/Operator Can Perform; Check Engine Oil Level; Check Battery - Generac Power Systems 4.6L Owner's Manual

ENGINE COOLANT

Check coolant level in coolant recovery bottle. See the
"Specifications" section.
• Add recommended coolant mixture as necessary.
• Periodically remove radiator pressure cap to make sure the
coolant recovery system is functioning properly. Coolant
should be at bottom of radiator filler neck. If coolant level is
low, inspect gasket in radiator pressure cap. Replace cap, if
necessary. To have pressure cap tested, contact an Authorized
Service Dealer. Inspect cooling system and coolant recovery
system for leaks.
MAINTENANCE OWNER/
OPERATOR CAN PERFORM

Before working on the generator, ensure the
following:
• The AUTO/OFF/MANUAL switch is in the OFF position.
• The 15A fuse has been removed from the control box.

• The negative battery cable has been removed.

CHECK ENGINE OIL LEVEL

Refer to the "Checking Fluid Levels" section.

CHECK BATTERY

• Check battery fluid level each week as outlined under "Check
Fluid Levels".
• Check battery cables for condition, tightness, corrosion or dam-
age. Clean, tighten or replace as necessary.

EXERCISE SYSTEM

Start the Stationary Emergency Generator engine at least once
every seven days and let it run at least 20 minutes. For more
detailed exercise information, see the respective sections in the
Control Panel Technical Manual that is supplied with the unit.

INSPECT COOLING SYSTEM

• Inspect engine cooling system at least once each month.
• Check hoses for damage, deterioration, leaks, etc. Correct any
discrepancies found.
• Check hose clamps for tightness.

CHECK ENGINE COOLANT LEVEL

See the "Checking Fluid Levels" section.

PERFORM VISUAL INSPECTION

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

INSPECT EXHAUST SYSTEM

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

CHECK FAN BELT

• Inspect fan belts every three months. Replace any damaged,
deteriorated, worn or otherwise defective belt.
• Check fan belt tension. Thumb pressure, exerted midway
between pulleys, should deflect about 3/8 to 5/8 inch. Adjust
belt tension as required.

INSPECT ENGINE GOVERNOR

Visually inspect electronic governor.
Do not attempt to adjust the governor. 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 voltage. Only qualified ser-
vice technicians should adjust the governed
speed.

CHANGING ENGINE OIL

Hot oil may cause burns. Allow engine to
cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
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 running. 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 com-
pletely into suitable container.
3. When all oil has drained, install and tighten OIL DRAIN HOSE
CAP , and re-install into its retaining clip.
4. Turn OIL FILTER (Figure 10.2) counterclockwise and remove.
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
OVERTIGHTEN.
