This manual contains Excavator specifications. Specifications are added to this manual upon completion.
All specifications in this manual are taken from current Testing and Adjusting manuals for each machine.
Engine specifications for the tables of this manual are the responsibility of the dealer. Because of the numerous engine arrangements and possible modifications, the Engine specifications will not be listed.
When possible, all of the factory specifications are listed in the appropriate columns. If the factory specifications are not available, "N/A" will be listed.
The "Customer" column on the tables should be used to record the specifications that relate to modifications after production. This column can be used to record a baseline of information on new equipment after predelivery inspection and delivery.
The "Reference" column on the tables should be used as a reference to determine the test that was used to reach the specification.
The pages that contain the information in this manual can be copied in order to create a specific, dedicated list of specifications for each customer. The list should be kept with other information for the maintenance log of the machine.
Some of the "Cycle Times" for the 200 Excavators are different from the inspection procedures. In these cases, the specifications will be given in the "Reference" column of the tables.
