Carriage Rigidity It is essential that the carraige fits snugly on the column to prevent the motor or bit from wobbling during drilling. Through normal use the carraige may loosen from the column and begin to wobble. Before drilling, always make sure the carraige is rigid by trying to wiggle it with your hand. If the carraige is secure it should not move. If it does move, tighten the adjustment screws for the nylon gibs that secure the carraige to the column. Tighten only enough to remove the play.
WARNING If using the vacuum base, do not continue operations unless the vacuum gauge reads more than 20 inches of mercury. Normally, the gauge will read 23 inches or more. 6. Turn the motor switch on the control box on. Turn the water on so that an adequate flow of water is supplied through the water swivel, to the bit. Hold the handle and slightly loosen the carriage lock knob. Slowly rotate the handle to lower the bit into the work piece - apply steady even pressure.
When drilling holes that are longer than the core bit, follow the steps below. Deep Drilling 1. Begin drilling the hole as usual. When you have drilled to the length of the bit, retract the bit from the hole and turn off the motor and water as usual. 2. Break off the core by driving a chisel or slender wedge into the circular kerf. Remove the core using core tongs, bent music wire or anchor bolts. 3.
Troubleshooting PROBLEM When trouble occurs, be sure to check the simple causes which, at first, may seem too obvious to be considered. Refer to the table below for problems and their possible causes. WHAT TO DO? INDICATION CAUSE 1. Check fluid return. Fluid not muddy. Evidence of steel cuttings Drilling in steel reinforcement Adjust drilling parameters to recommendations for reinforcement Speed not correct for the bit size used See recommended speeds 2.
PROBLEM WHAT TO DO? Bit Stuck 1. Try to raise bit, if impossible: 2. Stop rotation Shear Pin Fail 1. Stop rotation 2. Raise bit Warranty Information INDICATION SOLUTION/ RECOMMENDATIONS Loose material (cut steel or aggregates) is blocking between core and bit or between borehole and bit. Step 1: Apply wrench and rotate bit in both directions while bit is under tension. If not successful: Drill moved during drilling (poor fastening). Disconnect bit and remove, break core.
