Jet 725000 Operating Instructions Manual

4 Never reach around or over a rotating sawblade. Reaching for a workpiece may lead toaccidental contact with the moving saw blade. Provide auxiliary workpiece support to the rearand/or sides of the saw table for long and/orwide workpieces to keep them level. A longand/or wide workpiece has a tendency to pivot onthe table’s edge, causing loss of control, saw bladebinding and kickback. Feed workpiece at an even pace. Do not bend ortwist the workpiece. If jamming occurs, turn thetool off immediately, unplug the tool then clearthe jam. Jamming the saw blade by the workpiececan cause kickback or stall the motor. Do not remove pieces of cut-off material whilethe saw is running. The material may becometrapped between the fence or inside the saw bladeguard and the saw blade pulling your fingers intothe saw blade. Turn the saw off and wait until thesaw blade stops before removing material. Use an auxiliary fence in contact with the tabletop when ripping workpieces less than 2 mmthick. A thin workpiece may wedge under the ripfence and create a kickback.Kickback causes and related warningsKickback is a sudden reaction of the workpiece due to apinched, jammed saw blade or misaligned line of cut inthe workpiece with respect to the saw blade or when apart of the workpiece binds between the saw blade andthe rip fence or other fixed object.Most frequently during kickback, the workpiece is liftedfrom the table by the rear portion of the saw blade and ispropelled towards the operator.Kickback is the result of saw misuse and/or incorrectoperating procedures or conditions and can be avoidedby taking proper precautions as given below. Never stand directly in line with the saw blade.Always position your body on the same side ofthe saw blade as the fence. Kickback may propelthe workpiece at high velocity towards anyonestanding in front and in line with the saw blade. Never reach over or in back of the saw blade topull or to support the workpiece. Accidentalcontact with the saw blade may occur or kickbackmay drag your fingers into the saw blade. Never hold and press the workpiece that isbeing cut off against the rotating saw blade.Pressing the workpiece being cut off against thesaw blade will create a binding condition andkickback. Align the fence to be parallel with the saw blade.A misaligned fence will pinch the workpiece againstthe saw blade and create kickback. Use a featherboard to guide the workpieceagainst the table and fence when making non-through cuts such as rabbeting, dadoing orresawing cuts. A featherboard helps to control theworkpiece in the event of a kickback. Use extra caution when making a cut into blindareas of assembled workpieces. The protrudingsaw blade may cut objects that can cause kickback. Support large panels to minimize the risk of sawblade pinching and kickback. Large panels tendto sag under their own weight. Support(s) must beplaced under all portions of the panel overhangingthe table top. Use extra caution when cutting a workpiece thatis twisted, knotted, warped or does not have astraight edge to guide it with a miter gauge oralong the fence. A warped, knotted, or twistedworkpiece is unstable and causes misalignment ofthe kerf with the saw blade, binding and kickback. Never cut more than one workpiece, stackedvertically or horizontally. The saw blade couldpick up one or more pieces and cause kickback. When restarting the saw with the saw blade inthe workpiece, center the saw blade in the kerfso that the saw teeth are not engaged in thematerial. If the saw blade binds, it may lift up theworkpiece and cause kickback when the saw isrestarted. Keep saw blades clean, sharp, and withsufficient set. Never use warped saw blades orsaw blades with cracked or broken teeth. Sharpand properly set saw blades minimize binding,stalling and kickback.Table saw operating procedure warnings Turn off the table saw and disconnect the powercord when removing the table insert, changingthe saw blade or making adjustments to theriving knife, anti-kickback pawls or saw bladeguard, and when the machine is left unattended.Precautionary measures will avoid accidents. Never leave the table saw running unattended.Turn it off and don’t leave the tool until it comesto a complete stop. An unattended running saw isan uncontrolled hazard. Locate the table saw in a well-lit and level areawhere you can maintain good footing andbalance. It should be installed in an area thatprovides enough room to easily handle the sizeof your workpiece. Cramped, dark areas, anduneven slippery floors invite accidents. Frequently clean and remove sawdust fromunder the saw table and/or the dust collectiondevice. Accumulated sawdust is combustible andmay self-ignite. The table saw must be secured. A table saw thatis not properly secured may move or tip over. Remove tools, wood scraps, etc. from the tablebefore the table saw is turned on. Distraction or apotential jam can be dangerous.
