WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Never use water or any liquids to clean or rinse off your product and do not expose the product to rain or wet conditions. Store indoors in a dry area. Corrosive liquids, water, and chemicals can enter the product's electronic components and/or battery compartment and damage electronic components and/or the battery pack, which can result in a short circuit, increased risk of fire, and serious personal injury. Remove any buildup of dirt and debris by wiping the product clean with a dry cloth occasionally. NOTICE: Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced.

Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. TRANSPORTING AND STORING Always place the scabbard on the blade before storing or transporting the hedge trimmer. Use caution to avoid the sharp teeth of the blade. Clean the hedge trimmer thoroughly before storing. Store the hedge trimmer indoors, in a dry place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts. LUBRICATING THE BLADES See Figure 6. WARNING: Always allow the blades of the hedge trimmer to come to a stop and remove the battery pack before lubricating. Failure to do so could result in accidental starting causing possible serious personal injury. For easier operation and longer blade life, lubricate the hedge trimmer blade before and after each use. Remove the battery pack from the hedge trimmer. Lay the hedge trimmer on a flat surface. Apply light weight machine oil along the edge of the top blade. NOTE: If you will be using the hedge trimmer for an extended time, it is advisable to oil the blade periodically. Stop the hedge trimmer. Remove the battery pack. Lubricate the hedge trimmer as described above. Reinstall the battery pack and resume use. SHARPENING THE BLADE See Figure 7. Allow the blades of the hedge trimmer to come to a stop in the position shown. This will allow clearance for the file between the cutter teeth and the guard teeth. Remove the battery pack from the hedge trimmer. Clamp the blade assembly in a vise and file the exposed cutting surface of each blade tooth with an 8 in. smooth round file, 1/4 in. or 7/32 in. in diameter. Be sure to retain the original angle of the tooth when filing. Remove the hedge trimmer from the vise, replace the battery pack, and restart the hedge trimmer. Allow the blades of the hedge trimmer to come to a stop so that the unsharpened edges on the other side of the cutter blade teeth are exposed. Remove battery pack from hedge trimmer and repeat the sharpening procedure as described above. 10 - English
