The system also helps to keep the pre -7 TRIGGER "ON-OFF" SWITCH To turn the tool “ON” squeeze the trigger switch. To turn the tool “OFF”, release the trigger switch, which is spring loaded and will return to the “OFF” position automatically. To increase switch life, do not turn switch on and off while tool is under load. VARIABLE SPEED DIAL Your tool is equipped with a variable speed dial. The impact rate (BPM) and rotating speed (RPM) can be varied according to the type of work being performed by setting the variable speed dial to the selected setting. The chart below will help you to determine which setting to use for your application. However, a pre-test will determine the best speed setting, as the chart is intended only as a guide. Once the proper setting is determined the impact rate and rotating speed is kept constant by means of the "Electronic Feedback Circuitry". The variable speed dial can be adjusted while the motor is running with the tool free from work, allowing the operator to adjust the impact rate and rotating speed according to the actual application. CHIPPING (DEMOLITION) Area of application Control setting Plaster work 1 - 2 Removing tiles 3 Brick work 4 Concrete 5 - 6 DRILLING HOLES Lower speeds Higher speeds Accurate starts Faster penetration Minimize breakouts when the bit exits the material. selected impact rate and rotating speed virtually constant between no-load and load conditions. INSTALLING ACCESSORIES Clean the insert shank end of the accessory to remove any debris, then lightly grease with a light oil or lubricant. Insert accessory into the tool holder through the dust shield, while twisting and pushing inward until it locks automatically into place. Pull outward on the accessory to be certain it is locked into the tool holder (Fig. 2). NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The "cost" to maintain sharp and undamaged accessories is more than offset by the "time saved" in operating the tool with sharp accessories. REMOVING ACCESSORIES !WARNING Accessories may be hot after use. Avoid contact with skin and use proper protective gloves or cloth to remove. To remove an accessory, pull and hold locking sleeve backward and pull bit forward. All accessories should be wiped clean after removing. FIG. 2 LOCKING SLEEVE BM 1619929472 2-05 2/17/05 11:52 PM Page 8 SELECTOR LEVER The selector lever allows the tool to be set for various applications as listed in the following chart, (Fig. 3). When using demolition or chipping bits such as bull points, chisels, spades, gouges, etc. the “Hammer Only” mode must be selected. SELECTOR LEVER - “VARIO-LOCK” The vario-lock can be set in any one of twelve positions (30° increments). Choose a position which is best suited for your operation. The FIG. 3 Vario-Lock position is intended for use with chipping bits such as bull points, spades, gouges, etc. Depress release button and turn the selector lever, to the “vario-lock” setting. Next, rotate the locking sleeve, along with the accessory, to the desired position. Then turn the selector lever to the “hammer only” setting and slightly turn the locking sleeve to have it automatically lock into a definite position. Drilling/Hammering: Vario-Lock: Hammering Only: used for drilling with solid allows chisel to be set in used for chipping carbide bits and core bits one of 12 positions and demolition work (right or left “0” position) SLIP CLUTCH The tool has a internal pre-set slip clutch. The output spindle will stop rotating if the accessory binds and overloads the tool. 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...
