[. . . ] Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Use the power tool, accessories and tool bits etc. In accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Keep handles dry, clean and free from oil and grease. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to concrete vibrator safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. Always keep your hands and face away from vibrating head when operating. Switch off the tool immediately if you notice abnormal noise or something faulty during operation. Inspect the tool carefully for breakage, cracks or deformation if you accidentally drop it or strike it against something. Do not carry the tool with finger on switch. Do not set the tool down and switch it on. The vibrating head may whip around out of control and cause an accident. Be careful not to allow water, wet concrete or the like to get into the tool. Do not let the tool fall into wet concrete. Insert the vibrating head carefully between iron/ steel frames or reinforcing rods not to come in contact with them. Use a wet cloth or the like to carefully wipe off any wet concrete left on the tool after use. Extra care should be given to thorough cleaning of the vents, switch area, cover openings, etc. Ensure the switch is in the off position before inserting battery pack. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Switch lever can be pulled from either top or back side of the tool. [. . . ]
