BM 1619929470 2-05 2/18/05 12:02 AM Page 8 AUXILIARY HANDLE The tool must be supported with the auxiliary handle , which can be swiveled 360˚. To reposition and/or swivel the handle, loosen the hand grip, move the handle to the desired position along the barrel and securely retighten the hand grip. "TOOL TIPS" For the best penetration rates in concrete, run the tool with a steady pressure, but do not use excessive force as this will decrease the efficiency of the tool. All grease packed hammers require a short period of time to warm up. Depending on the room temperature, this time may vary from approximately 15 seconds (90˚F) to 2 minutes (32˚F). A new hammer requires a break-in period before full performance is realized. This period may require up to 5 hours of operation. An electric hammer is likely to be the most expensive portable tool at the construction job. The long wear and efficient operation of the BOSCH hammers will more than justify the cost for tools of this type. As earlier pointed out, sharp accessories as well as clean air vents are necessary for efficient operation. Establish and follow a set maintenance program. -8-
