To Clean The Generator; Engine Maintenance; Checking Oil Level; Changing The Oil - Generac GP Serie Manual De Propietario

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 every 100 hours. 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 Champion N9YC spark plug or equivalent. Replace the plug
once each year. This will help the engine start easier and run
better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the 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
(Figure 12).

3.4 SERVICE AIR FILTER

The engine will not run properly and may be damaged if using a
dirty air filter. Clean the air filter every 200 hours or once a year
(Figure 13). Clean or replace more often if operating under dusty
conditions. The air filter part number is 0G84420151.
• Remove air filter cover.
• Wash in soapy water. Squeeze filter dry in clean cloth (DO NOT
TWIST).
• Clean air filter cover before re-installing it.
To order a new air filter, please contact the nearest authorized
service center at 1-888-436-3722.
