English / USA MAINTENANCE, REPAIR AND STORING Servicing of double-insulated appliance This electric chainsaw is doubleinsulated. In such an appliance, two systems of insulation are provided instead of grounding. No grounding means are provided, nor should means for grounding be added to the appliance. Servicing a double-insulated appliance requires extreme care and knowledge of the system, and should be done only by qualified service personnel. !Warning! Replacement parts for double-insulated appliance must be identical to the parts they replace. !Warning! Use only STIHL replacement parts for maintenance and repair. Use of parts manufactured by others may cause serious or fatal injury. !Warning! Never operate a chainsaw that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate section of your Owner's Manual, especially those in the chapters " Mounting the Bar and Chain" "Maintaining and Sharpening" and "Chain Brake". !Warning! Always stop the motor, disconnect the plug from the power supply and ensure that the chain is stopped before making any adjustments, maintenance or repair work, changing the saw chain or cleaning the saw. Do not attempt any maintenance or repair work not described in your Owner's Manual. Have such work performed at your STIHL service shop only. Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut and burn marks appear on the wood. Keep the chain at proper tension. Tighten all nuts, bolts and screws before each use. Only authorized personnel may replace the power supply cord. A damaged power supply cord must be replaced by an identical STIHL replacement part. !Warning! In order for the chain brake on your STIHL chainsaw to properly perform its function of reducing the risk of kickback and other injuries, it must be properly maintained. Like an automobile brake, a chainsaw chain brake incurs wear each time it is engaged. The amount of wear will vary depending upon usage, conditions under which the saw is used and other factors. Excessive wear will reduce the effectiveness of the chain brake and can render it inoperable. For the proper and effective operation of the chain brake, the brake band and drum must be kept free of dirt, grease and other foreign matter which may reduce friction of the band on the drum. For these reasons, each STIHL chainsaw should be returned to trained personnel such as your STIHL servicing dealer for periodic inspection and servicing of the brake system according to the following schedule: Heavy usage - every three months, Moderate usage - twice a year, Occasional usage - annually.
