Maintenance Tips

• Clean after use — remove grass clippings and debris from the trimmer head and guard to prevent buildup and maintain cutting efficiency.

• Replace or reload line — check your bump‑and‑feed line often and reload/replace when worn for consistent cutting performance.

• Protect battery contacts — keep 40V Max XGT battery and tool terminals clean and dry for reliable power transfer.

• Charge & store batteries right — recharge before deeply discharged; store packs in a cool, dry place to maximize life and performance.

• Inspect shaft & fasteners — tighten screws/handles periodically to counter vibration and maintain tool stability.

• Avoid moisture exposure — do not submerge or wash with high‑pressure water; wipe damp spots and let dry.

• Use appropriate speed settings — match the 3‑speed or torque drive mode to conditions to reduce wear and extend runtime.

• Store safely — keep trimmer and batteries in a dry, cool area away from direct sun and extreme heat
