Section 4
4.1 — Maintenance Schedule
Follow the calendar intervals. More frequent service is required when
operating in adverse conditions noted below.
Check Oil Level............................................................... At Each Use
Change Oil ‡................................ *Every 100 hours or Every Season
Check Valve Clearance ............................................***Every Season
Service Air Filter ........................** Every 200 hours or Every Season
Replace Spark Plug ...................................................... Every Season
‡ Change oil after first 30 hours of operation then every season.
* Change oil and oil filter every month when operating under heavy load or in high tem-
peratures.
** Clean more often under dirty or dusty operating conditions. Replace air filter parts if
they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of operation and
every 300 hours thereafter. This requires some engine disassembly. We recom-
mend contacting an Authorized Service Dealer for this adjustment.
Once a year replace the spark plug and replace the air filter. A
new spark plug and clean air filter assure proper fuel-air mixture
and help the engine run better and last longer.
4.2 — General Recommendations
The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value from
the warranty, the operator must maintain the generator as instructed
in this manual.
Some adjustments will need to be made periodically to properly main-
tain the generator.
All adjustments in the Maintenance section of this manual should be
made at least once each season. Follow the requirements in the
"Maintenance Schedule".
4.2.1 — Generator Maintenance
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will not
be exposed to excessive dust, dirt, moisture or any corrosive vapors.
Cooling air slots in the generator must not become clogged with snow,
leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on its
exterior surface.
*
Never insert any object or tool through the air cooling
slots, even if the engine is not running.

Maintenance
NOTE:
4.2.2 — 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.
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 wind-
ings will eventually decrease the insulation resistance of these
4.2.3 — Engine Maintenance
+
When working on the generator, always disconnect
spark plug wire from spark plug and keep wire away from
spark plug.
4.2.4 — 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 main-
tained.
4.2.5 — 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:
1.
Clean area around oil drain plug (Figure 4-1).
2.
Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
3.
When oil has completely drained, install oil drain plug and tighten
securely.
NOTE:
windings.
