They are double-insulated in accordancewith European Standard and can, therefore, also beused from sockets without earth wire.Safety hintsFor your own safety, please refer to enclosed safetyinstructions.These symbols mean:Read instruction manual.DOUBLE INSULATIONADDITIONAL SAFETY RULESFOR MACHINE1. Wear ear protectors.2. Check the socket carefully for wear, cracks ordamage before installation.3. Hold the machine firmly.4. Always be sure you have a firm footing. Besure no one is below when using the machinein high locations.5. The proper tightening torque may differdepending upon the kind or size of the bolt.Check the torque with a torque wrench.SAVE THESE INSTRUCTIONS.OPERATING INSTRUCTIONSSelecting correct socketUse a correct size socket for bolts and nuts. A wrongsize socket will result in inaccurate and inconsistenttightening torque.Installing the side grip (Fig. 1)For 6906 onlyFit the side grip into the groove on the middle of thehammer case and fasten securely.Attaching the socket (Fig. 2)Selecting a proper socket in size, please insert it intothe anvil so as to fix securely.Switch action (Fig. 3)CAUTION:• Before plugging in the machine, always check tosee that the switch trigger actuates properly andreturns to the ‘‘OFF’’ position when released.• Change the direction of rotation only after themachine comes to a complete stop.
