GENERAL SAFETY RULES

Failure to follow these rules may result in serious personal injury.

1.FOR YOUR OWN SAFETY, READ THE INSTRUCTION MANUAL BEFORE OPERATING THE MACHINE. Learning the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury.

2.WEAR EYE AND HEARING PROTECTION. ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.

3.WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip protective footwear is recommended. Wear protective hair covering to contain long hair.

4.DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power tools in damp or wet locations or in rain can cause shock or electrocution. Keep your work area well-lit to prevent tripping or placing arms, hands, and fingers in danger.

5.MAINTAIN ALL TOOLS AND MACHINES IN peak CONDITION. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.

6.CHECK FOR DAMAGED PARTS. Before using the machine, check for any damaged parts. Check for alignment of moving parts, binding of moving parts, breakage of parts, and any other conditions that may affect its operation. A guard or any other part that is damaged should be properly repaired or replaced with Delta or factory authorized replacement parts. Damaged parts can cause further damage to the machine and/or injury.

7.KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.

8.KEEP CHILDREN AND VISITORS AWAY. Your shop is a potentially dangerous environment. Children and visitors can be injured.

9.REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is in the “OFF” position before plugging in the power cord. In the event of a power failure, move the switch to the “OFF” position. An accidental start-up can cause injury. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.

10.USE THE GUARDS. Check to see that all guards are in place, secured, and working correctly to prevent injury.

11.REMOVE ADJUSTING KEYS AND WRENCHES BEFORE STARTING THE MACHINE. Tools, scrap pieces, and other debris can be thrown at high speed, causing injury.

12.USE THE RIGHT MACHINE. Don’t force a machine or an attachment to do a job for which it was not designed. Damage to the machine and/or injury may result.

13.USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by Delta may cause damage to the machine or injury to the user.

14.USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. See the Extension Cord Chart for the correct size depending on the cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

15.SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece when practical. Loss of control of a workpiece can cause injury.

16.FEED THE WORKPIECE AGAINST THE DIRECTION OF THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE SURFACE. Feeding it from the other direction will cause the workpiece to be thrown out at high speed.

17.DON’T FORCE THE WORKPIECE ON THE MACHINE. Damage to the machine and/or injury may result.

18.DON’T OVERREACH. Loss of balance can make you fall into a working machine, causing injury.

19.NEVER STAND ON THE MACHINE. Injury could occur if the tool tips, or if you accidentally contact the cutting tool.

20.NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN THE POWER OFF. Don’t leave the machine until it comes to a complete stop. A child or visitor could be injured.

21.Turn the machine “OFF”, and disconnect the machine from the power source before installing or removing accessories, changing cutters, adjusting or changing set-ups. When making repairs, be sure to lock the start switch in the “OFF” position. An accidental start-up can cause injury.

22.MAKE YOUR WORKSHOP CHILDPROOF WITH PADLOCKS, MASTER SWITCHES, OR BY REMOVING STARTER KEYS. The accidental start-up of a machine by a child or visitor could cause injury.

23. STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE

COMMON SENSE. DO NOT USE THE MACHINE WHEN YOU ARE TIRED OR UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR MEDICATION. A moment of inattention while operating power tools may result in injury.

24. Use of this tool can generate and disburse dust or other airborne particles, including wood dust, crystalline silica dust and asbestos dust. Direct particles away from face and body. Always operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.
