Version 2.0.0. Required observations are marked *. Your answers stay in this browser.

Dry tool, removed battery and secure indoor storage. Original guide illustration; compare the parts with your manual.

1. Match the model and parts

Remove the battery. Find LST300 and the adjacent type number on the tool label. Compare the guard, cap, spool and assembly figures with the linked LST300 manual. Use ServiceNet for your exact type if they differ. LST300 is not a bump-feed head.

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.

Model and tool typeRemove 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 headDo not substitute a bump-feed procedure, dual-line spool or metal cutting attachment.

Choose the versions you can confirm.

2. Prepare

Stop and get help

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.

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 cleaningMaterial: No replacement material needed for an intact tool

Yes — Record the label type and matching manual reference in the first step.
No — An unknown type, unavailable type manual, different figures, bump-feed head or dual-line conversion blocks this procedure. Use manufacturer support to identify the correct instructions.
Not sure — Keep the battery removed. Save your preparation record and check the matching manual before continuing.

Is the tool free of damage and can its exterior be cleaned and dried safely?

Yes — Clean before choosing the final storage position.
No — Keep damaged equipment out of service and obtain support before reuse.
Not sure — Keep the battery removed. Save your preparation record and check the matching manual before continuing.

Is a dry, secure indoor location available away from children, fertilizers and chemicals?

Not sure — Keep the battery removed. Save your preparation record and check the matching manual before continuing.

4. Follow and record

Complete the checks before recording physical work. Follow steps in order.

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.
Tool type exactly as printed on the label *Exact-type manual reference or link that you matched *I completed this step and checked the observation.
Manual: Official model/type lookup instructions; type is beside or below the model number
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.
I completed this step and checked the observation.
Manual: English pp2–3 Safety; p8 Installing and removing the battery pack
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.
I completed this step and checked the observation.
Manual: English p10 Maintenance items 1, 3; p3 Safety
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.
Storage location *I completed this step and checked the observation.
Manual: English p3 Store idle trimmers indoors; pp5, 7 Battery safety / Storage recommendations
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.
My next inspection date *I completed this step and checked the observation.
Manual: English p3 Store idle trimmers indoors; pp5, 7 Battery safety / Storage recommendations
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.
