OPERATING INSTRUCTIONS RH170 Introduction

Warranty

The warranty of Bucyrus HEX presupposes among other things that the servicing works as described in the operating instructions have been performed:

 by the Bucyrus HEX Service or

 in a workshop authorized in writing by Bucyrus HEX, and

 by using the original spare parts of Bucyrus HEX.

The proper execution of the servicing works must be documented on the Bucyrus HEX Service checklists.

Do not operate the machine

 when components / assemblies are defective or missing,

 if one or several of such components of which more than one are installed in the machine have been removed.

In cases of doubt seek advice from the Bucyrus HEXService.

Bucyrus HEX refuses to assume the guarantee for damage and consequential damage caused by an abusive utilization of the machine.

Therefore:

Do not operate the machine,

 when several track rollers or support rollers have been removed;

 when one or several slewing gearboxes have failed or been removed;

 when one or several teeth on the backhoe or on the shovel are worn or missing;

 when parts of the hardfacing layer on the backhoe or on the shovel are worn or missing.

Working under these circumstances results in heavy wear and possibly in severe damage and thus in high repair costs.

Such circumstances are considered by Bucyrus HEX as "abusive utilization".

Why?

The machines have been designed and built on the basis of detailed calculations and so that all of the components installed absorb the occurring forces and are thus loaded to an equal extent.

Example:

If the machine is used for working with, for instance, one or even several track rollers removed, the forces must be absorbed by the remaining track rollers. These are then overloaded or loaded to a greater extent than calculated.

The consequences are higher wear and consequential damage to the track rollers, but also to other components of the machine: chassis, travel gearbox and crawler track.
