949-11001
Thanks for purchasing this Walthers SceneMaster kit. All parts are styrene, so use compatible glue and paint to assemble
and finish your model. PLEASE NOTE: Parts are assembled in numerical sequence: #1 to #2, #1& 2 to #3 etc. With careful
assembly, several parts are positionable; parts marked * snap in place, but may be glued if desired. Please take a few
minutes to read these instructions and study the drawings. Individual parts are not numbered on sprues; use the diagram
below to identify parts during assembly.
Tracing their origins to the first steam shovels of the 1800s, gasoline and later diesel-powered cable excavators were
standard heavy equipment well into the 1970s and beyond. Using a series of clutches, gears and chains, the operator
could engage winding drums to tighten or loosen wire ropes (“cables”), rotate the cab, or move the machine as needed.
Many were set up to work various attachments, including a shovel as depicted by this model. Sturdy crawler tracks allowed
for sure-footed off-road operation in a variety of settings ranging from construction projects to mines and quarries. For
additional products to complete your model, see your participating hobby dealer, check out the latest Walthers Model
Railroad Reference Book or visit us online at walthers.com.
