☞ Use suitable means to support and secure the machine
☞ In addition, ensure that the machine cannot overturn
Checking track tension
Check track tension as follows:
☞ Park the dumper on firm and level ground
☞ Raise the dumper with suitable means
☞ Tracks must be raised off the ground
☞ Stop the engine
☞ Use additional supports for the dumper and ensure that it cannot overturn
☞ Measure the clearance at the middle track roller A
➥ The rubber track should not sag more than 15 mm when tight
If possible, the distance from the rollers should be the same for both tracks.
Increasing track tension
Proceed as follows:
☞ Park the dumper on firm and level ground
☞ Raise the dumper with suitable means
☞ Tracks should be raised off the ground
☞ Stop the engine
☞ Use additional supports for the dumper and ensure that it cannot overturn
