Prepare the trimmer for storage ID: lst300-storage Version: 2.0.0 Model: BLACK+DECKER LST300 · US · AF-100 Region: US Parts: Automatic-feed head with AF-100 spool; match model and tool type to manual Not covered: LST420 / LSTE525; GH corded models; Dual-line heads; Metal line or blades; Nonmatching tool type or modified head; Unknown tool type or missing exact-type manual; Bump-feed conversion MATCH YOUR VERSION Model and tool type: LST300 and the exact type on my label match my manufacturer manual and figures Remove the battery before finding the label. Use the manufacturer model-and-type lookup; this site does not infer a type number from LST300 alone. Cutting head: Original AF-100 automatic-feed single-line head Do not substitute a bump-feed procedure, dual-line spool or metal cutting attachment. PREPARE [ ] Release the trigger, let the head stop, engage the lock-off and remove the battery. Leave it removed throughout hands-on care. Keep fingers away from the sharp cutter on the guard. [ ] Read LST300 and the tool type from the label. Open the official model/type lookup and compare its manual and parts figures with your actual guard, single-line head and AF-100 spool. A readable model name alone does not establish the type. If the exact type manual cannot be obtained, or any figure differs, save a preparation record and stop. [ ] Tool: Soft rag if exterior needs cleaning [ ] Material: No replacement material needed for an intact tool STOP Keep the battery removed if the exact type/manual match is unknown or parts differ from the figures. Stop for a damaged battery, exposed wiring, a faulty switch, cracked guard, broken spool/hub, damaged cap tabs or housing slots. Use an authorized service center. Never open the battery, motor housing or charger.

Record the exact tool and make it safe Release the trigger, let the head stop, engage the lock-off and remove the battery. Leave it removed throughout hands-on care. Keep fingers away from the sharp cutter on the guard. Read LST300 and the tool type from the label. Open the official model/type lookup and compare its manual and parts figures with your actual guard, single-line head and AF-100 spool. A readable model name alone does not establish the type. If the exact type manual cannot be obtained, or any figure differs, save a preparation record and stop. Look for: The battery is physically separate from the tool; your label type and matching manual reference are written below. Source: bd-manual-help, Official model/type lookup instructions; type is beside or below the model number [ ] 2. Separate the battery and record condition After the head has stopped, remove the battery and keep it separate during cleaning and storage. Inspect the tool and battery exterior for damage. Do not open or attempt to restore a damaged pack. Look for: The battery is removed and any damage is recorded for service. Source: lst300-manual, English pp2–3 Safety; p8 Installing and removing the battery pack [ ] 3. Remove the remaining dirt Use the housing-cleaning method to clear accessible grass and wipe plastic with mild soap on a damp rag if needed. Keep liquid out of every opening. Leave the exterior and handles fully dry. Look for: There is no loose external grass buildup or damp grip. Source: lst300-manual, English p10 Maintenance items 1, 3; p3 Safety [ ] 4. Choose a safe indoor position Store the trimmer indoors in a dry, locked place beyond children’s reach. Keep it away from fertilizers and chemicals. Position it securely so the guard cutter cannot be touched accidentally. Look for: The storage position is dry, secure and separate from chemicals. Source: lst300-manual, English p3 Store idle trimmers indoors; pp5, 7 Battery safety / Storage recommendations [ ] 5. Place the battery and charger appropriately Use the matching battery and charger manuals for their storage. This manual calls for a cool, dry place away from sunlight and excessive heat or cold, and warns against loose metal touching battery terminals. Keep the battery sealed and out of the tool. Look for: The pack terminals cannot contact loose keys, screws or other conductive objects. Source: lst300-manual, English p3 Store idle trimmers indoors; pp5, 7 Battery safety / Storage recommendations [ ] 6. Save a return-to-use plan Record the storage location and choose a personal date to inspect the tool again. Your chosen date is a reminder, not a manufacturer interval. Before the next use, check guard, cap, handle and line through after-care. Look for: The record names a storage location and a user-selected next inspection date.
