Ridgid R82008N Operation Manual - Page 9

OPERATION 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 material. 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. NOTE: This drill has an electric brake. When the switch trigger is released, the chuck stops turning. When the brake is functioning properly, sparks will be visible through the vent slots on the housing. This is normal and is the action of the brake. MAINTENANCE 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. METAL DRILLING For maximum performance, use high speed steel bits for metal or steel drilling.  Begin drilling at a very low speed to prevent the bit from slipping off the starting point.  Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will: • Overheat the drill; • Wear the bearings; • Bend or burn bits; and • Produce off-center or irregular-shaped holes.  When drilling large holes in metal, start with a small bit, then finish with a larger bit. Also, lubricate the bit with oil to improve drilling action and increase bit life. WARNING: When servicing use only identical RIDGID® replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. WARNING: To avoid serious personal injury, always remove the battery pack from the tool when cleaning or performing any maintenance. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at a RIDGID authorized service center. BATTERY PACK REMOVAL AND PREPARATION FOR RECYCLING WARNING: Upon removal, cover the battery pack's terminals with heavy-duty adhesive tape. Do not attempt to destroy or disassemble battery pack or remove any of its components. Lithium-ion batteries must be recycled or disposed of properly. Also, never touch both terminals with metal objects and/or body parts as short circuit may result. Keep away from children. Failure to comply with these warnings could result in fire and/or serious injury. NOTE: FIGURES (ILLUSTRATIONS) START ON PAGE 11 AFTER FRENCH AND SPANISH LANGUAGE SECTIONS. 9 - English
