General

WARNING Make sure that you have been trained and are familiar with the use of machines on slopes, and
understand the adverse affects that slopes and site conditions can have on stability. Never use the machine
on a slope if you do not understand the recommended practices for the use of machines in such applications.
There are a number of factors which can adversely affect the stability of the machine and the safety of the
machine and operator when used on a slope.
It is essential that a risk assessment of the work to be done is completed and that the operator complies with
any safety precautions that the assessment identifies.

Driving on Slopes

Introduction
WARNING Operating the machine on hillsides can be dangerous if proper precautions are not taken. Ground
conditions can be changed by rain, snow, ice etc. Check the site carefully. Going uphill, reverse when
unloaded or travel forwards when loaded. Going downhill, travel forwards when unloaded or reverse when
loaded. Take special care when moving across a slope. If the slope is too steep your machine could roll
over. If you must drive across a slope, keep the attachments close to the ground.
The machine can operate without affecting its systems on slopes of up to 35°. On slopes greater than 10° the
operator must use his discretion and continue with extreme caution.
Driving Down a Slope
When you drive down a slope, make sure that the bucket is set 250 ± 50mm above the ground (in the position
shown) and drive at a low speed. Refer to Figure 156.
When you drive down a slope always keep the drive sprockets at the front. If the drive sprockets are at the
rear, the tracks will be loose and there is a danger the machine could move unexpectedly after it stops.
Keep the dig end in a position that makes sure the machine is stable and at the same time where it is possible,
to use the dig end to stop the machine in an emergency.
The steering speed is quite fast when you drive down a steep slope. If it is necessary to change direction, stop
the machine and turn the track backward on the side to which the machine will turn. This will improve safety
when you turn on a slope. Refer to Figure 157.
