Owner’s manual
Can I use .095 trimmer line?
Yes, you can use .095-inch trimmer line on many setups, but on a Hitachi CG22EAS you should match the line size and head style listed in the owner's manual. Using the correct flexible, non-metallic nylon line helps the head feed properly and reduces vibration.
What the CG22EAS manual says about line
The manual emphasizes using Hitachi nylon cutting line and warns against using wire or other materials that can become a dangerous projectile. It also notes that if the cutting head does not feed line properly, the line and components may be installed incorrectly.
How to decide if .095 is a good fit
Use these checks before you spool up .095 line:
- Confirm the cutting head type (semi-auto/bump feed vs. other) in the owner's manual.
- Check the head’s maximum line diameter; many heads accept multiple sizes, but not all.
- Watch for feeding issues after restringing (line not advancing when tapped at low RPM).
- Avoid “up-sizing” for power; thicker line can reduce RPM and increase load on a small 2-cycle trimmer.
- Never use metal line (wire, cable, or wire rope).
Quick comparison: .080 vs .095 line (typical)
| Line size | Best for | Typical tradeoff |
|---|---|---|
| .080 in | Light to medium trimming | Easier feeding, less engine load |
| .095 in | Heavier weeds, thicker grass | More load, can feed worse in small heads |
If you install .095 and it will not feed
Try these fixes (engine off for any hands-on work):
- Rewind the spool neatly; avoid cross-winding and tangles
- Verify the line is routed through the eyelets correctly
- Make sure the head is securely mounted
- Tap to feed only at low RPM (the manual notes not greater than about 4,500 RPM)
- Set line length to the manual’s operating range (about 11 to 14 cm exposed)
Why it matters
Correct line diameter and proper installation protect the cutting head, improve cut quality, and help prevent unsafe breakage or poor feeding during operation.

What is the best string trimmer line to use?
For the Hitachi CG22EAS gas line trimmer, the best trimmer line is flexible, non-metallic nylon line recommended for the cutting head; we also recommend sticking with Hitachi nylon cutting line for the most consistent feeding and durability. See the owner's manual for the exact line type and setup details.
What to use (and what to avoid)
Use nylon line that matches the trimmer head design and guard/line limiter setup.
- Use nylon cutting line (flexible, non-metallic)
- Use Hitachi nylon cutting line for best performance and reliability
- Avoid wire, wire rope, or any metal-reinforced line (it can break and become a projectile)
- Make sure the line and head components are installed correctly so the head feeds properly
- Adjust line length before trimming so the guard can limit it correctly
Recommended line length for CG22EAS
Before each use, set the nylon line to the proper operating length.
| Item | CG22EAS guidance |
|---|---|
| Line material | Flexible, non-metallic nylon |
| Line length before operation | 4-11/32 to 5-1/2 in. (11 to 14 cm) |
| Metal line (wire/wire rope) | Do not use |
Quick setup checks if line will not feed
If your semi-auto cutting head is not advancing line when tapped, we use these checks first.
- Stop the engine and confirm the cutting head is securely mounted to the gear case
- Reinstall the line and spool components in the correct order
- Confirm the guard and guard extension are installed correctly (a loose guard can affect line limiting)
- Inspect the line for melting, welding, or kinks from overheating
- Tap-to-feed only at low RPM (semi-auto heads feed when tapped at low speed)
Why it matters
Correct nylon line helps the CG22EAS cut cleanly, feed smoothly, and reduce safety risks. Using metal line or incorrect setup increases the chance of dangerous debris and poor cutting performance.

How do I find the model number on my CG22EAS?
The model number is printed on the trimmer’s identification label; on Hitachi CG22EAS units it typically appears as “CG22EAS” (sometimes with a suffix like SLP or SL). Use the exact model from the label when looking up diagrams, manuals, and parts.
Where to look on a Hitachi CG22EAS trimmer
Check these common label locations on a gas line trimmer:
- On the engine housing near the recoil starter (pull-start) cover
- On the shaft tube near the throttle handle
- Near the fuel tank area on the main body
- On a sticker or metal plate close to the muffler side (look carefully for heat discoloration)
If the label is dirty or faded, wipe it with a damp rag first; avoid harsh solvents that can remove printing.
What the model number can look like
The CG22EAS family includes several closely related versions. Your label may show one of these formats:
| What you see on the label | What it means | Why it matters |
|---|---|---|
| CG22EAS | Base model family | Good starting point for manuals and diagrams |
| CG22EAS (SLP) or CG22EAS (SL) | Specific version/suffix | Helps match the correct parts and specs |
| CG22EAD or CG22EAB | Different model family | Parts and settings can differ |
For confirmation of the model family naming used in documentation, reference the [CG22EAS owner’s manual].
Why it matters
Small differences in suffix (like SLP vs SL) can change items such as the carburetor setup, fuel system parts, or ignition components. Using the exact model from the ID label helps ensure the right fit and correct service information.
Quick tips if you still cannot read the label
- Take a close-up photo in bright light and zoom in
- Look for stamped characters on the metal engine case (if present)
- Match the trimmer’s major assemblies (starter cover style, handle type) to the diagrams once you have the closest model name
