METHOD FOR OPENING AND CLOSING ENGINE HOOD
kk
CAUTION
• When opening or closing the engine hood, place the machine on a level ground, lower the work
equipment to the ground, stop the engine, then perform the operation.
• When opening the engine hood, do not release the handle until the stay is set in the lock position
securely.
• When closing the engine hood, hold the handle securely since the engine hood may move down be-
cause of its own weight.
If the engine hood is not locked, it may close suddenly because of wind, etc.
• Immediately after the engine is stopped, the engine hood and after-treatment devices are still hot.
Accordingly wait until they have cooled down before opening or closing the engine hood.
