MAINTENANCE
7-34
Replenish Engine Oil
CAUTION:
• Shut down the engine when fueling. Do not smoke
while fueling ─
──
─ or when handling fuel containers.
• Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire.
• After fueling, secure filler cap.
Recommended Oil Viscosities
Two important considerations related to satisfactory en-
gine operation under ambient temperature conditions ─
(1) the ability to crank the engine fast enough to assure
starting, and (2) adequate lubrication of internal wearing
surfaces during starting and warm-up.
Recommended oil viscosities are SAE15W-40 for all
seasons, shown in the chart below:

Engine Oil Level --- check daily
IMPORTANT: For most accurate readings, check the
oil level every day before starting the
machine. Be sure the machine is on a
level surface.
1. Remove dipstick (1). Wipe oil off with a clean cloth.
Reinsert dipstick (1).
2. Remove dipstick (1) again. Read level. Oil level must
be between the circle marks.
3. If necessary, add oil via oil filler cap (2).
Be sure to use only recommended oil (see Recom-
mended Engine Oil Chart).
NOTE: Checking the oil level immediately after shut
down will result in inaccurate readings.
Be sure to allow the oil to settle for at least 10
minutes before checking.
