on the trailer.
●
It is dangerous to load or unload your ma-
chine with the work equipment. The use of
an access ramp is necessary.
●
On an access ramp, never maneuver any
other control lever except the travel control
lever.
●
At the junction of the access ramp and
trailer, the machine's center of gravity may
change suddenly and it is possible to loose
balance. Drive slowly when passing the
junction.
●
If you have to swing the work equipment
on the trailer, be extra careful with your
machine, which may tip over due to insta-
ble base.
If the work equipment has been installed
on the machine, it must be retracted slowly
to avoid the machine loosing balance.
●
Considering operating safety, a signal man
shall be assigned to alert preventing the
machine from falling off the ramp.
The following items must be carefully ob-
served:
●
Use an access ramp with enough width,
length, thickness and strength. Ramp
grade shall not exceed 15°.
●
When piling the earth to build a platform,
the platform must be fully compacted to
prevent landslide.
●
To prevent the machine from skidding
on the ramp, clean its track shoes and
the ramp before loading and unloading.
The machine has the danger to skid when
the access ramp is contaminated with wa-
ter, snow, grease or ice.
