WARNING:
•
Never attempt to travel on slopes with grade of 10 °
(17%) or more.
•
Don't operate actuators other than travel motors
while driving up or down slopes.
•
Avoid driving across the face of a slope, possibly
creating hazardous conditions.
•
Don't operate the travel mode switch while driving
the machine. If the fast travel mode is unintention-
ally selected while driving up or down slopes, tip-
ping over of the machine may result due to impact
loads.
•
The machine stability may suddenly change at a
point where the slope inclination changes. Care-
fully operate the machine to prevent the machine
from tipping over.

Align the front attachment in parallel with the longitudi-
nal center direction of the crawlers and position the ma-
chine with the travel motors at the rear.
3. Face the front attachment and the travel motors toward
the up-hill side and down hill side respectively.
