TRANSPORTING AND STORING See Figure 44. ¦ Do not store or transport the chain saw when it is running. The chain saw should always be idle before storing or transporting. ¦ Always place the guide bar scabbard on the bar and chain before storing or transporting the chain saw. Use caution to avoid the sharp teeth of the chain. ¦ Clean the chain saw thoroughly before storing. Store the chain saw indoors, in a dry place that is locked and/or inaccessible to children. ¦ Keep away from corrosive agents such as garden chemicals and de-icing salts. Fig. 44 BATTERIES The battery pack for your chain saw is equipped with nickel-cadmium rechargeable batteries. Length of service from each charging will depend on the type of work you are doing. The batteries in this tool have been designed to provide maximum trouble free life. However, like all batteries, they will eventually wear out. Do not disassemble battery pack and attempt to replace the batteries. Handling of these batteries, especially when wearing rings and jewelry, could result in a serious burn. To obtain the longest possible battery life, we suggest the following: ¦ Store and charge your batteries in a location where the temperature is above 50°F but less than 100°F. ¦ Never store batteries in a discharged condition. Recharge them immediately after they are discharged. ¦ All batteries gradually lose their charge. The higher the temperature the quicker they lose their charge. If you store your chain saw for long periods of time without using it, recharge it every month or two. This practice will prolong battery life. DISPOSAL OF THE EXHAUSTED BATTERY To preserve natural resources, please recycle or dispose of properly. This product contains a nickel- cadmium battery. Must be disposed of properly. Local, state, or federal laws may prohibit disposal of Nickel- Cadmium batteries in ordinary trash. Consult your local waste authority for information regarding available recycling and/or disposal options. For more information on battery recycling call 1-800-8BATTERY. BATTERY PACK PREPARATION FOR RECYCLING WARNING: Upon removal, cover the battery pack’s terminals with heavy duty adhesive tape. Do not attempt to destroy or disassemble battery pack or remove any of its components. Also, never touch both terminals with metal objects and/or body parts as short circuit may result. Keep away from children. Failure to comply with these warnings could result in fire and/or serious injury. 30 BAR AND CHAIN COMBINATIONS RECOMMENDED BAR AND CHAIN COMBINATIONS Bar Part Number - 10 in.
