3.2 Rev. 1-09 Shaded area indicates changes MUELLER ® LARGE DRILLING MACHINES Mueller CL-12 ™ Machine features ❏ Automatic Feed Travel Indicator - as the cut progresses, the direct reading indicator automatically subtracts, always showing the amount of travel remaining in automatic feed. You always know just how much of the cut remains to be made. ❏ Rapid Hand Travel - when not cutting, the boring bar can be quickly and easily advanced or retracted by hand. Rapid advancement and retraction of the boring bar reduces time of operation. ❏ Automatic Tool Position Indicator - direct reading indicator continually shows the position of the pilot drill and shell cutter in relation to their fully retracted or rearmost position. Large numerals read in inches and tenths of an inch and automatically add as the tool is advanced, and subtract as the tool is retracted. Eliminates tool position guesswork. ❏ Automatic Feed Setting - the amount of travel required in automatic feed can be quickly and accurately set in inches and tenths of an inch. This amount is clearly shown on the automatic feed travel indicator to assure accurate settings every time. ❏ Automatic Feed Disengagement - when the preset travel in automatic feed is completed and the indicator reads zero, the tool feed is automatically disengaged. ❏ Ratchet Handle - all working parts are totally enclosed; easily lubricated. ❏ Rugged All Steel Construction - all working parts are totally enclosed in a strong steel case to permit complete lubrication and prevent damage from dirt and other foreign matter. ❏ Handling Ease - telescopic design reduces overall length and weight. Conveniently placed handles and front and rear lifting yokes aid in handling the machine. The front lifting yoke may also be used to lock the boring bar while attaching or removing tools. ❏ Hand or Power Operation - may be hand operated with ratchet handle provided or power operated with MUELLER H-614 air power operator or H-607 hydraulic operator. ❏ Self-Adjusting Boring Bar Packing - high temperature chevron packing is spring-loaded to ensure positive, leakproof sealing without packing adjustments. Line pressure does not enter case.
