POTENTIAL HAZARD
If you leave the wire on the spark plug, someone could start the engine.
WHAT CAN HAPPEN
Someone accidentally starting the engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
Remove the wire from the spark plug before you do any maintenance. Set the wire aside so it
does not accidentally contact the spark plug.
Checking the Engine Oil Level
Before you use the lawn mower, make sure that the oil
level between the Add and the Full marks as shown on the
dipstick (Fig. 5). If the oil level is below the Add mark,
add oil. Refer to Filling the Crankcase with Oil on
page 8.
Changing the Engine Oil
Change the oil after the first five operating hours and then
after every 50 operating hours or every season. Run the
engine just before changing the oil to warm the oil. Warm
oil flows better and carries more contaminants.
Note: Change the oil after every 25 operating hours when
operating under heavy load or in high temperatures.
