• • ENG313-1 WARNING: The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used. Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).
Personal safety 11. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. 12. Use personal protective equipment. Always wear eye protection.
dangerous in the hands of untrained users. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. 23. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. 24.
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations: a) Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. b) The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator.
e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. f) Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
To start the tool, push in the lock lever (in the A direction) and then pull the switch trigger (in the B direction). Release the switch trigger to stop. For tool with the lock on and lock-off switch To prevent the switch trigger from accidentally pulled, a lock lever is provided. To start the tool, push in the lock lever (in the A direction) and then pull the switch trigger (in the B direction). Release the switch trigger to stop.

Inner flange • CAUTION: Do not use Ezynut with Super Flange or angle grinder with "F" on the end of the model No. Those flanges are so thick that the entire thread cannot be retained by the spindle. 1 010654 Mount the inner flange onto the spindle.
NOTE: • Ezynut can be loosened by hand as long as the arrow points the notch. Otherwise a lock nut wrench is required to loosen it. Insert one pin of the wrench into a hole and turn Ezynut counterclockwise. Operation with wire cup brush (optional accessory) • OPERATION • • • • • • • • • WARNING: It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.
Thread wire wheel brush onto spindle and tighten with the wrenches. When using wire wheel brush, avoid applying too much pressure which causes over bending of wires, leading to premature breakage. Installing or removing abrasive cut-off wheel / diamond wheel (optional accessory) 1 Operation with abrasive cut-off / diamond wheel (optional accessory) 78 2 WARNING: When using an abrasive cut-off / diamond wheel, be sure to use only the special wheel guard designed for use with cut-off wheels.
When the resin insulating tip inside the carbon brush is exposed to contact the commutator, it will automatically shut off the motor. When this occurs, both carbon brushes should be replaced. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.
