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. 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.

Regardless of the pressure applied on the trigger, the tool will not operate any faster than maximum speed setting selected. "TURBO" FEATURE In the "Hammer Only" mode power is automatically increased 20% when the tool is turned on to provide maximum chiselling performance. CONSTANT RESPONSE CIRCUITRY The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also helps to keep the preselected impact rate and rotating speed virtually constant between no-load and load conditions. SELECTOR LEVER The selector lever allows the tool to be set for various applications as listed in the following chart, (Fig. 4). When using demolition or chipping bits such as bull points, chisels, spades, gouges, etc. the “Hammer Only” mode must be selected.
