How do you reload a trimmer spool?
To reload the spool on your Craftsman line trimmer model 358798151-32CC, cut the correct length of trimmer line, feed it into the spool’s anchor hole/slot, then wind the line tightly in the direction shown on the spool so it feeds smoothly during trimming.
Step-by-step: reload and wind the line
- Shut the trimmer off and let the engine cool; disconnect the spark plug boot for safety.
- Remove the bump knob and spool from the trimmer head.
- Clean out packed grass and dirt so the line can feed freely.
- Cut a fresh piece of line (most trimmers use 10 to 20 feet total; use what fits your spool without overfilling).
- Insert the line end into the spool’s retaining hole/slot to “hook” it so it will not unravel.
- Wind the line tight and even in the direction of the arrow (or the direction the head rotates during use).
- Leave about 4 to 6 inches of line free, then route the end through the eyelet(s) and reinstall the spool and bump knob.
Quick checks if the line will not feed
- Overfilled spool: rewind with less line.
- Wrong wind direction: rewind to match the spool arrow.
- Loose winding: rewind under steady tension.
- Worn line: replace with a fresh piece; old line can swell and stick.
- Dirty head/eyelets: clean the head and eyelet openings.
Line size and loading tips (typical)
| What you are choosing | What works best | What to avoid |
|---|---|---|
| Line diameter | Use the size recommended for your head (commonly 0.080 in or 0.095 in) | Oversize line that binds and will not feed |
| Line length | Enough to fill the spool without bulging | Packing line tight until the spool jams |
| Winding | Tight, level wraps | Crossed wraps that snag |
Why it matters
A correctly loaded spool keeps the cutting line feeding consistently, reduces vibration, and prevents premature wear on the trimmer head and bump-feed parts.

How do I know what size trimmer line I need?
For your Craftsman line trimmer model 358798151-32CC, choose trimmer line size based on what you cut and what the trimmer head is designed to accept: light grass uses thinner line, while thicker weeds need thicker line. Using the correct diameter prevents poor feeding and bogging.
Quick sizing guide (what you’re cutting)
- Light trimming (short grass, edging): use thin line (about 0.050 to 0.065 inch)
- General yard work (average grass, light weeds): use medium line (about 0.065 to 0.080 inch)
- Heavier weeds (thick stems, tougher growth): use thicker line (about 0.080 to 0.095 inch)
- If the engine struggles or the head stops feeding, step down one size.
- If the line breaks constantly, step up one size (only if the head allows it).
How to confirm the correct line for 358798151-32CC
1) Check the trimmer head and spool
Most line trimmer heads have the line diameter molded or printed on the head, spool, or bump knob. Match that marking exactly.
2) Match the line to the correct spool or line kit
If you prefer a pre-cut or matched option, use a model-compatible line kit such as the line kit 530069247.
3) Use the right line shape for the job
| Line type | Best for | Tradeoff |
|---|---|---|
| Round | Everyday trimming | Longest life, slower cutting |
| Square/star | Faster cutting in weeds | Wears faster, can be noisier |
| Twisted | Quieter, smoother cut | Not as aggressive as square |
Why it matters
Correct line diameter and type help your Craftsman 358798151-32CC maintain RPM, reduce clutch and head wear, and improve cutting performance. Oversized line commonly causes poor acceleration, stalling, and uneven line feed.

Do trimmer plus attachments work with Craftsman?
Some TrimmerPlus attachments work with Craftsman powerheads, but compatibility depends on whether your Craftsman 358798151-32CC has an attachment-capable coupler (a split-shaft connection). If your trimmer has a fixed straight shaft with no coupler, TrimmerPlus attachments will not fit.
How to tell if your 358798151-32CC is attachment-capable
Look at the shaft between the engine and the cutting head:
- A coupler section with a clamp/knob or lever that loosens to separate the shaft
- A locking/detent pin hole near the coupler
- A removable lower shaft section (not a one-piece shaft)
- Attachment branding on the shaft or guard that says “attachment-capable”
- A drive connection inside the coupler (often a square drive end)
What to compare before you buy an attachment
Use this quick check to avoid a mismatch.
| Check point | What must match | What happens if it does not |
|---|---|---|
| Coupler style | Split-shaft, attachment-capable coupler | Attachment cannot mount securely |
| Drive type | Same inner drive end (often square) | Attachment mounts but will not spin |
| Shaft fit | Correct diameter and full seating | Vibration, wobble, premature wear |
| Locking method | Pin alignment and clamp style | Slipping or unsafe operation |
If the attachment “almost fits”
Do not force it. These signs point to the wrong coupler or drive style:
- Pin hole will not line up
- Attachment clamps but still wiggles
- Head does not turn under throttle
- Excess vibration immediately after install
If you find loose or stripped hardware while checking the shaft and handle area, replacing the correct fastener can help restore a solid assembly (for example, screw 530016406).
Why it matters
Using an incompatible attachment can strip the drive connection, loosen the shaft joint, and create unsafe vibration. Confirming the coupler and drive match protects the Craftsman powerhead and the attachment.
