HAMMER DRILL SAFETY WARNINGS WARNING! Do not operate the power tool until you have read and understood the following instructions and the warning labels. HAMMER DRILL SAFETY 1.Work Environment. Do not operate the tool in wet or damp conditions; doing so significantly increases the risk of electrical shock. Do not operate the tool in the presence of flammable liquids or gases. 2. Personal Safety. Always wear ANSI Z87.1-approved glasses, hearing protection and dust mask when using the drill.
ELECTRICAL INFORMATION (CHARGER) DOUBLE-INSULATED CHARGER The charger’s electrical system is double-insulated where two systems of insulation are provided. This eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are isolated from the internal metal components with protecting insulation.
BATTERY & CHARGER SAFETY WARNINGS Despite all of the safety precautions, caution must always be taken when handling batteries. The following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect handling of the battery pack can cause cell damage. • Avoid dangerous environments – Do not charge the battery pack in rain, snow or in damp or wet locations.
BATTERY & CHARGER SAFETY WARNINGS ABOUT THE BATTERY 1. The battery pack has to be charged completely before you use the tool for the first time. 2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently. 3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new.
