Controls and Operation

Starting Procedure (Gas Models): Set switch to ON, press primer bulb 5-10 times, set choke, pull starter cord briskly.

Electric Models: Insert battery or plug in, then press safety lock and trigger.

Operating Tips: Hold trimmer at slight angle so line cuts at tip. Use a sweeping side-to-side motion. For edging, tilt trimmer vertically. Avoid cutting near fences, trees, or hard surfaces to prevent line wear.

Stopping: Release throttle/trigger. For gas models, move switch to OFF. Disconnect spark plug wire for storage.

Trimmer Line Replacement

  1. Disconnect spark plug or battery/power.
  2. Remove spool: Press tabs or turn cap to release cutting head spool.
  3. Remove old line: Clean spool of debris.
  4. Wind new line: Cut two lengths of recommended line (typically 10-20 ft). Insert ends into spool anchors and wind in direction of arrows.
  5. Reassemble: Place spool back into head, threading line ends through eyelets. Snap or screw cap back on.
  6. Test: Pull line ends to ensure they feed freely.

Tip: Soak trimmer line in water overnight to increase flexibility and durability.

Maintenance & Storage

Regular maintenance ensures long life and safe operation.

  1. After each use: Clean debris from guard and cutting head. Wipe exterior.
  2. Air filter (gas): Clean or replace per schedule. Do not operate with dirty filter.
  3. Spark plug (gas): Check gap and condition annually; replace if worn.
