keep wire away from spark plug.
4.3.2 — Oil Level Check
See the "Before Starting the Generator" section for infor-

eight hours of operation. Keep the oil level maintained.
See Figure 4-1 for the dipstick and oil fill location.

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.

before draining oil. Avoid prolonged or
repeated skin exposure with used oil. Thor-
oughly wash exposed areas with soap.
Use the following instructions to change the oil after the
engine cools down:

ing the Generator" for oil recommendations).
5. Fill to the upper level on the dipstick. See Figure 4-2.
