Make sure hidden electrical wiring, water pipes, and mechanical hazards are not in the blade path when cutting into a wall. GENERAL CUTTING See Figure 5. Hold the saw firmly in front of and clearly away from you. Make sure saw blade is clear of any foreign material. Be sure material to be cut is held firmly. Small workpieces should be securely clamped in a vise or with clamps to the work bench or table. n Mark the line of cut clearly. n Pull variable speed switch to start the cutting action. n Place the base assembly against the workpiece, then move the blade into the workpiece. Do not force. Use only enough pressure to keep the saw cutting. Let the blade and saw do the work. Use of excessive pressure that causes bending or twisting of the blade may result in broken blades. WARNING: Hold tool by insulated gripping surfaces when performing an operation where the saw blade may contact hidden wiring or its own card. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. Fig. 6 Fig. 5 ® ® PLUNGE CUTTING See Figure 6. n Mark the line of cut clearly. n Choose a convenient starting point inside the area to be cut out and place the tip of the blade over that point. n Rest front edge of base (shoe) assembly on workpiece and hold firmly in position. n Pull variable speed switch to start the cutting action. WARNING: Make sure blade does not touch workpiece until motor reaches full speed, since this could cause loss of control resulting in serious injury. n With saw blade at full cutting speed, slowly tilt saw downward until tip of blade starts cutting workpiece. n After blade penetrates workpiece, tilt saw until blade is perpendicular to the workpiece. 11 OPERATION METAL CUTTING See Figure 7. Metalssuch assheet steel,pipe,steelrods,aluminum,brass, and copper may be cut with the saw. Be careful not to twist or bend the saw blade. Do not force. We recommend using cutting oil when cutting most soft metals and steel. Cutting oil will also keep blades cool, increase cutting action, and prolong blade life. Never use gasoline since normal sparking of motor could ignite fumes. Clamp the workpiece firmly and cut close to the clamping point to eliminate any vibration of the workpiece being cut. When cutting conduit pipe or angle iron, clamp workpiece in a vise if possible and cut close to the vise. To cut thin sheet material, “sandwich” the material between hardboard or plywood and clamp the layers to eliminate vibration and material tearing. MAINTENANCE ® Fig. 7 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. 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. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air. LUBRICATION All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. 12 MAINTENANCE BRUSH REPLACEMENT BRUSH ® See Figure 8. NOTE: The reciprocating saw is equipped with externally accessible brushes. nUnplug the saw. WARNING: Failure to unplug the tool could result in accidental starting causing possible serious injury. NOTE: Brush caps (2) are located on the top and bottom of the motor housing in front of the handle. nRemove brush caps (2) using a screwdriver. nRemove brush assemblies (2). nCheck for wear. Replace both brush assemblies when either has less than 1/4 in. length of carbon remaining. NOTE: Do not replace one side without replacing the other. nReassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube. nReassemble by reversing the steps listed above. nTighten all brush caps securely. Do not over tighten. Fig. 8 BRUSH CAP ASSEMBLY BRUSH CAP BRUSH ASSEMBLY 13 NOTES WARRANTY RIDGID® HAND HELD AND STATIONARY POWER TOOL 3 YEAR LIMITED SERVICE WARRANTY Proof of purchas...
