Checking Engine Oil Level

WARNING
Risk of burns. Allow engine to cool before
draining oil or coolant. Failure to do so could
result in death or serious injury.
WARNING
Skin irritation. Avoid prolonged or repeated contact with
used motor oil. Used motor oil has been shown to cause
skin cancer in laboratory animals. Thoroughly wash
exposed areas with soap and water.
CAUTION
Engine damage. Verify proper type and quantity of
engine oil prior to starting engine. Failure to do so
could result in engine damage.
IMPORTANT NOTE: Verify oil level daily when power
outages necessitate running generator for extended
periods. Generator will shut down if oil level is low.
Proceed as follows to check engine oil level:
1. Allow generator to run for a cool-down period of
approximately one minute, if generator was run-
ning during an outage.
2. Set generator MLCB (generator disconnect) to
OFF (OPEN).
3. Press OFF button to turn generator off. Wait five
minutes.
4. See Figure 2-1. Remove oil dipstick and wipe it dry
with a clean cloth.
5. Completely insert oil dipstick into oil dipstick tube
and remove.
6. Observe oil level. The level should be at FULL
mark on oil dipstick.
7. If necessary, remove oil fill cap and add recom-
mended oil to engine (with oil dipstick removed)
until level reaches FULL mark. Insert oil dipstick
and install fill cap. See
To restart generator:
1. Press AUTO button on control panel.
2. Set generator MLCB (generator disconnect) to ON
(CLOSED).
3. Verify generator is enabled in PWRgenerator
device page on PWRcell control panel.
