Checking the Engine Oil
Check the engine oil level before each use, or every 10 hours
if operated continuously. Check the engine oil level with the
engine stopped and in a level position.
1. Remove the oil fill cap/dipstick and wipe it clean with a
paper towel (see Figure 5).
2. Insert and remove the oil filler cap/dipstick without screwing
it into the oil filler neck, then remove it to check the oil level
shown on the dipstick.
3. If the oil level is near or below the lower limit mark on
the dipstick, fill to the bottom edge of the oil fill hole with
SAE 10-30W engine oil. See the SAE Viscosity Chart for
other oil weights and temperatures (see Figure 6). To avoid
overfilling or underfilling, be sure the engine is in a level
position while adding oil.
4. Reinstall the oil filler cap/dipstick and tighten securely.
Changing the Engine Oil
1. Allow the engine to cool slightly. The engine oil will flow
more quickly when still warm. Be careful of draining hot oil.
2. Remove the oil fill cap, invert the power driver and carefully
drain the engine oil into an approved container for disposal.
3. Return the power driver to its upright position on a level
surface.
4. Some oil will remain in the engine after draining. When
refilling with fresh oil, start with about 2 ounces. Slowly add
SAE 10-30W engine oil into the oil fill and wait one minute
for the oil to settle, then continue filling with oil. Slowly add
enough oil to fill to the bottom edge of the oil fill hole (see
Figure 5).
5. Replace the dipstick. Be careful not to overfill.
