Ridgid R7001 Operation Manual - Page 9

OPERATION WARNING: Make sure to insert the drill bit straight into the chuck jaws. Do not insert the drill bit into the chuck jaws at an angle then tighten, as shown in figure 6. This could cause the drill bit to be thrown from the drill, resulting in possible serious personal injury or damage to the chuck.  Tighten the chuck jaws securely on the bit. NOTE: Rotate the chuck body in the direction of the arrow marked GRIP to close the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws. TO REMOVE BITS  Unplug the drill.  Open the chuck jaws. NOTE: Rotate the chuck body in the direction of the arrow marked RELEASE to open the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws.  Remove the drill bit. LOCK-ON BUTTON See Figure 7, page 13. This drill is equipped with a lock-on feature, which is convenient for continuous drilling for extended periods of time. To lock-on:  Depress the switch trigger.  Push in and hold the lock-on button, located on the side of the handle.  Release the switch trigger.  Release the lock-on button and the drill will continue running.  To release the lock, depress and release the switch ­trigger. If the lock-on feature is engaged during use and the drill becomes disconnected from the power supply, disengage the lock-on feature immediately. WARNING: Before connecting the drill to a power supply source, always check to be sure it is not in lock-on position (depress and release the switch trigger). Failure to ensure that it is not locked-on could result in accidental starting of the drill resulting in possible serious injury. Do not lock the switch trigger in applications where the drill may need to be suddenly stopped. DRILLING See Figures 8 - 9, page 13.  Depress and release the switch trigger to be sure the drill is in the OFF position before connecting it to a power supply.  Check the direction of rotation selector for the correct setting (forward or reverse).  Secure the material to be drilled in a vise or with clamps to keep it from turning as the drill bit rotates.  Plug the drill into power supply. Hold the drill firmly and place the bit at the point to be drilled.  Depress the switch trigger to start the drill.  Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting. Do not force the drill or apply side pressure to elongate a hole. Let the tool do the work. WARNING: Be prepared for binding at bit breakthrough. When these situations occur, drill has a tendency to grab and kick opposite to the direction of rotation and could cause loss of control when breaking through materials. If not prepared, this loss of control can result in possible serious injury.  When drilling hard, smooth surfaces, use a center punch to mark the desired hole location. This will prevent the drill bit from slipping off-center as the hole is started.  When drilling metals, use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling action.  If the bit jams in the workpiece or if the drill stalls, stop the tool immediately. Remove the bit from the workpiece and determine the reason for jamming. WOOD DRILLING For maximum performance, use high speed steel bits for wood drilling.  Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as the drill bit bites into the material.  When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on the back side of the hole. 9 - English
