The ESSIG MOLE however cannot be used in solid rock and is not designed for use against unfracturable rocks Also soft soils as in a swamp may present problems in accuracy as the tool s own weight may cause it to deviate In normal operation however the patented reciprocating stepped cone chisel head and long cylindrical shape ensure maximum boring accuracy Normally when a boring tool encounters a rock the tool is pushed off course The reciprocating action of the ESSIG MOLE however will break a rock up and allow the tool to pass In addition if the tool should encounter an unfracturable rock the ESSIG MOLE can easily be reversed and retrieved to re start the bore Operation of the ESSIG MOLE Connection to a Compressor Like any pneumatic tool ESSIG MOLE requires a compressor with adequate capacity for optimal operation Please see the technical data to determine the quantity of air required for each individual ESSIG MOLE model Note that the operating pressure must not exceed 100 psi Operating the ESSIG MOLE at pressures higher than 100 psi will invalidate the warranty Before connecting the ESSIG MOLE blow air through the air hoses to remove any dirt or other contamination Page 6 of 12 TYPICAL ESSIG MOLE CONNECTION SEQUENCE MODELS 45 110 Make sure that the couplings are securely interlocked and safety rings are tightened before the machine is started Wrap the couplings with adhesive or electrical tape to keep dirt fro

E Tool Start operation of the ESSIG MOLE on reduced air pressure only Always run the ESSIG MOLE slowly into the ground continually checking the line and level with the SIGHT SCOPE Only when satisfied that all is correct should the ESSIG MOLE have full power from the compressor by fully opening the ball valve Check the SIGHT SCOPE for accuracy before each bore The control unit lubricator should always be within reach of the operator In case of danger to people or machine turn off the air supply from the compressor immediately Always watch the behavior and reaction of your colleagues In case of danger take the necessary steps immediately Use recommended oils and lubricants only Firmly hold or block the hose end when cleaning the hose with compressed air Point the hose away from body Do not point hoses at others Respect a minimum safety distance from any over head live lines When operating beneath railroad tracks all standards and requirements should be observed Machine and equipment should be removed from a job site on the track free side Never cross the tracks unless supervised Introduction to ESSIG MOLE The ESSIG MOLE boring tool is a cylindrical air hammer which is driven through the ground by compressed air Its bores are used for the laying of pipes and cables under roadways and other surface installations The ESSIG MOLE can be used in all isplaceable soils sand loam gravel even those soils containing fracturable rocks
