The small teeth of the blade and speed of the saw in conjunction with the base insert will prevent splintering or chipping of the top surface. Fig.` 3 PLUNGE CUTTING When cutting into a wall avoid contact with all exposed metal on the tool to prevent electrical shock hazard resulting from accidentally cutting into a live wire. HOLD SAW AS ILLUSTRATED IN FIG. 4. 10 One of the distinctive and important features of the Porter-Cable bayonet saw is the ability to start the cut (in wood only) within an area without making drilled holes first. This is especially important when making cut-outs for electric outlets in finished walls, openings in cabinet tops for sinks and openings for plumbing fixtures. First, measure the area to be cut out and mark it clearly with a pencil, chalk or scriber. Choose a convenient starting point and hold the bayonet saw over the point and inside the line of waste. Tip the machine forward until the front edge of the base rests firmly on the surface of the material with the tip of the blade clear of the work surface, as shown in Fig. 4. Turn motor “ON” and slowly lower the back of the machine allowing blade to bite into surface of work. Do not move the machine forward until the base is fully seated on the surface of the work. Now, guide the cutting along the inside of the marked area. If sharp corners are desired cut right up to the corner of the marked edge. Stop and back up just a bit, start the turn and cut along the side. Do the same at each corner until you end up where you started. Then, go back and cut into each corner from the opposite direction. The base of the machine is wide enough so you will have a solid guiding surface on either side of the cut. Fig.` 4 USING THE JIG SAW First, secure the material in a bench vise or with clamps to the work table. This is especially important when sawing small pieces or thin material. As the work progresses in scroll or curved cut-out pieces, the material can be re-adjusted to accommodate the movement of the saw. If the work is large enough, it may be held only by hand across saw horses or some other rigid support. The saw cuts freely with only light forward feed pressure on the tool. Forcing the saw will not cause it to cut faster. Be careful not to twist the saw while making the cut. This will cause blade breakage. To start the cut, secure the work, mark the line of cut clearly, place forward edge of saw base on edge of the material, start motor and when motor is up to desired speed, move blade into the work. NOTE: Because of the variable speed feature, trial cuts at varying speeds should be made on scrap material to determine the cutting speed for the most desirable results. 11 DO NOT FORCE, LET THE SAW DO THE WORK. Move saw forward only fast enough to keep blade cutting. If cutting becomes difficult, the blade is dull and should be changed at once. A dull blade not only makes cutting more difficult but also overburdens the motor. You will find the open throat and clear forward edge of the saw base make it easy to follow the line. LUBRICATION Although all Porter-Cable tools have been thoroughly lubricated with a sufficient amount of high grade lubricant at the time of manufacture, it is recommended that the oil level in the gear chamber be checked before using your saw and periodically thereafter as follows: DISCONNECT TOOL FROM POWER SOURCE. 1. Remove saw blade and set machine on a level surface. 2. Remove oil plug from front of machine. 3. Gear lubricant should be level with the bottom of the oil plug hole, but should not run out. If this condition does not exist, tip machine up and add a small amount of Porter-Cable lubricant until it is even with the bottom of the hole. 4. NOTE: DO NOT OVERFILL. If you do, the pressure created by the pumping action of the gears may force lubricant through seals and into motor and mechanism chamber causing damage to the machine. 5. To change lubricant in the mechanism housing it is necessary to dismantle the tool. This operation should only be performed by a AUTHORIZED PORTER-CABLE SERVICE STATION or a PORTERCABLE• DELTA FACTORY SERVICE CENTER. However, the lubricant may be checked as follows: A. Remove all traces of the sawdust and grime from around the gear housing and blade holder to eliminate the possibility of contaminating the mechanism lubricant. B. Remove four gear housing cover screws located around the knob on the left side of the machine. C. Lift off cover and gasket being careful not to damage the gasket. D. There should be a thin layer of lubricant around the blade holder. If this lubricant is contaminated, take your saw to an authorized Porter-Cable Service Station for a thorough cleaning and lubrication. If lubricant is needed, brush a thin coat of Porter-Cable lubricant on the blade holder. NOTE: An excessive amount of lubricant may leak through the blade holder dust seal and spatter on material being cut. E. Replace gasket and gear housing cover and tighten four screws securely. 12 TR...
