To Clean The Generator; Engine Maintenance; Checking Oil Level; Changing The Oil - Generac Power Systems 006000-0 Owner's Manual

DO NOT use a garden hose to clean generator. Water can enter
the engine fuel system and cause problems. In addition, if water
enters the generator through cooling air slots, some water will
be retained in voids and crevices of the rotor and stator winding
insulation. Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance of
these windings.

3.3.2 TO CLEAN THE GENERATOR

• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings
on the generator. These openings must be kept clean and
unobstructed.

3.3.3 ENGINE MAINTENANCE

When working on the generator, always

disconnect spark plug wire from spark plug and
keep wire away from spark plug.

3.3.4 CHECKING OIL LEVEL

See the "Before Starting the Generator" section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.

3.3.5 CHANGING THE OIL

Change the oil after the first 30 hours and every 100 hours
thereafter. If running this unit under dirty or dusty conditions, or in
extremely hot weather, change the oil more often.
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.
Use the following instructions to change the oil after the engine
cools down:
• Clean area around oil drain plug.
• Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
• When oil has completely drained, install oil drain plug and
tighten securely.
• Fill engine with recommended oil. (See "Before Starting the
Generator" for oil recommendations).
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.
NOTE:

3.3.6 REPLACING THE SPARK PLUG

Use NGK BPR7ES spark plug or equivalent. Replace the plug once
each year.
1. Stop the engine and shut off the fuel valve on the cylinder and
remove.
2. Using a 13mm wrench and 6mm Allen wrench, remove the
four (4) flat head screws and two (2) hex nuts from the side
panel and 3 button head screws adjacent to the top cover.
Remove the exhaust side panel to gain access to the spark
plug (Figure 13).
Figure 13 - Remove Screws
Nuts behind
these two
screws.
3. Remove the spark plug wire off of the plug and clean that area
of the cylinder head (Figure 14).

4. Use a 21mm (13/16") spark plug socket to remove the spark
plug.
5. Set the new spark plug's gap to 0.70-0.80 mm (0.028 – 0.031
in). Install the correctly gapped spark plug into the cylinder
head and tighten enough to ensure the gasket compresses at
(18.0 to 21.6 Pound/Feet) (Figure 15).
6. Reconnect the spark plug wire and replace the exhaust side
panel and seven (7) fasteners.
