Figure 14-24.-Tramming control panel.2. Backward: Pull both tramming control leversbackward.3. Pivot turn:Push the right or left trammingcontrol lever forward, and the unit pivots as the oppositetrack works as a fulcrum.4. Right turn: Push the left tramming control leverforward and pull the right tramming control leverbackward.5. Left turn: Push the right tramming control leverforward and pull the left tramming control leverbackward.6. Speed adjustment: The speed is controlled byadjusting the forward angles of the tramming controllevers.7. Stop: To stop the rock drill, release thetramming control levers. When the levers return to theneutral position, the machine stops automatically. At thesame time, the parking brake works. After completionof traveling, lock the levers.NOTE: When working in tight areas, stay aware ofyour surroundings, ensuring all personnel stay clear ofthe rock drill when traveling and turning.DRILLINGDrilling with the rock drill is performed from thedrilling control console (fig. 14-25).The functions of the componentscontrol console are as follows:of the drillingFigure 14-25.—Drilling control console.1. Fast feed control lever: This lever is used forcleaning the hole and for changing steel. When pushed,the drill moves forward at fast speed. When pulled, thedrill moves backward at fast speed. The lever returnsautomatically to neutral when released.2. Drill control lever:This lever controls thepercussion of the drifter. The drill pressure becomeshigher in proportion to the position of the lever.3. Rotation control lever: his lever controls theforward or backward rotation and rotation speed of thedrill steel.4. Slow speed control lever: This lever is usedwhen drilling boreholes and coupling and uncouplingdrill steel. When pushed, the drill steel moves forwardat a slow speed. When pulled, the drill steel movesbackward at a slow speed.5. Feed pressure adjusting control valve: Thiscontrol valve adjusts the feed pressure speed duringdrilling. When you pull and turn the knob to the right,the feed force increases. When you turn the knob to theleft, the feed pressure decreases.6. Feed pressure gauge: This gauge indicates theamount of discharged feed air pressure.7. Drill pressure gauge: This gauge indicates thedrill pressure during drilling.14-19
