b) en c) d) e) adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord.
c) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. d) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. e) Under abusive conditions, liquid may be ejected from the battery, avoid contact.
en placed under the panel on both sides, near the line of cut and near the edge of the panel. e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback. f) Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback. g) Use extra caution when making a “plunge cut” into existing walls or other blind areas.
stall, possibly causing the power tool to kick back. 5.2.6 Power tool use and care a) Secure the workpiece. Use clamps or a vice to secure the workpiece. The workpiece is thus held more securely than by hand and both hands remain free to operate the power tool. b) Check that the insert tools used are compatible with the chuck system and that they are secured in the chuck correctly. 5.2.7 Electrical safety a) Before beginning work, check the working area (e.g.
Insert the battery in the corresponding charger. 6.2 Charging the battery en CAUTION Use only the Hilti chargers listed under “Accessories”. DANGER Ensure that the outer surfaces of the battery are clean and dry before inserting it in the corresponding charger. Read the operating instructions for the charger for further information about the charging procedure. 6.2.1 Charging a new battery for the first time A new battery must be charged correctly for the first time before use.
CAUTION Wear protective gloves when changing blades. The blade, the clamping flange and the clamping screw get hot. CAUTION Check that the blade to be fitted complies with the technical requirements and that it is well sharpened. A sharp saw blade is an essential requirement for a perfect cut. 7.1.1 Removing the saw blade 2 1. Pull the battery out of the power tool. 2. Press the drive spindle lockbutton. 3. Turn the saw blade clamping screw with the hex. socket wrench until the locking pin engages fully. 4.
en front opening for the saw blade and at the end of the base plate. 1. Secure the workpiece so that it cannot move. 2. Position the workpiece so that the saw blade is free to move under the workpiece. 3. Check to ensure that the switch on the power tool is in the off-position. 4. Fit the battery into the power tool. 5. Place the power tool with the base plate on the workpiece in such a way that the blade still has no contact with the workpiece. 6.
8. Care and maintenance CAUTION Before beginning cleaning, remove the battery from the power tool in order to prevent unintentional starting. 8.1 Care of insert tools Clean off dirt and dust deposits adhering to the insert tools and protect them from corrosion by wiping the insert tools from time to time with an oil-soaked rag. 8.2 Care of the power tool The outer casing of the power tool is made from impact-resistant plastic. Sections of the grip are made from a synthetic rubber material.
