Checking And Adding Fluid
See the SERVICE SCHEDULE for the correct service
interval. (See SERVICE SCHEDULE on Page 134.)

If fluid can be reached with the tip of your finger through
the hole, the fluid level is correct.
If the level is low, add fluid through the check plug hole
until fluid flows from the hole.
Install and tighten the plug [Figure 264].
AVOID INJURY OR DEATH
Always clean up spilled fuel or oil. Keep heat, flames,
sparks or lighted tobacco away from fuel and oil.
Failure to use care around combustibles can cause
