Craftsman 358795540 weed trimmer Parts

For the Craftsman weed trimmer model 358795540, we recommend sticking with the manufacturer spec: 0.080-inch diameter Craftsman line. A .095-inch line is thicker than specified and can reduce cutting performance, overload the trimmer head, and make the engine work harder; check the owner's manual for the exact line guidance for your setup.

What to use on model 358795540

The manual calls out 0.080 inch (2 mm) diameter Craftsman brand line and warns against using substitutes like wire, rope, or string.

• Use 0.080-inch trimmer line for best feed and cutting balance
• Keep the cutting line at the proper length (too long increases load)
• Make sure the shield is installed correctly before trimming
• Replace cracked or damaged trimmer head parts before use
• Keep bystanders at least 50 feet away because line can throw debris

If you still want to run .095 line

We see some users prefer .095 for heavy weeds, but on this Craftsman gas trimmer it is a mismatch with the manual spec. If you choose to try it anyway, expect more drag and more frequent bogging.

Line size	Best for	What you may notice on 358795540
0.080 in (specified)	Everyday trimming, reliable feed	Smooth acceleration, normal head speed
0.095 in (thicker)	Heavy weeds (on trimmers designed for it)	Slower spool-up, more vibration, harder starting under load

Why it matters

Correct line diameter protects the trimmer head and helps the engine maintain RPM. Oversize line can make the clutch and cutting system work harder, which increases wear and can make the unit feel underpowered.

To replace trimmer line on your Craftsman 358795540 weed trimmer, shut the engine off, disconnect the spark plug, then reload the cutting head with the correct 0.080-inch (2 mm) round line so it feeds smoothly without tangling. Use the steps in the 358795540 owner's manual for your exact head style.

Before you start (safety and setup)

• Move the ON/OFF switch to OFF and let the engine cool
• Disconnect the spark plug wire before maintenance
• Wear gloves and eye protection
• Clean grass and debris off the trimmer head and shield
• Use only 0.080-inch (2 mm) round line (never wire, rope, or string)

How to reload the trimmer line (typical spool-style head)

1. Remove the spool cover (usually by pressing tabs or unscrewing the cap).
2. Pull out the old line and clean the spool and eyelets.
3. Cut two equal lengths of 0.080-inch round line (many heads use two pieces).
4. Feed each line end through the spool holes and wind in the direction shown on the spool.
5. Keep the wraps tight and even; do not overlap layers.
6. Thread the line ends through the eyelets, reinstall the spool and cover, then pull line to set it.

What “right line” means for this model

The manual for Craftsman 358795540 specifies 0.080-inch (2 mm) diameter round line. Using the wrong size or shape can prevent proper feeding and can damage the cutting head.

Item	Recommended	Avoid
Line diameter	0.080 in (2 mm)	Larger or smaller sizes
Line shape	Round	Square, star, twisted
Material	Nylon trimmer line	Wire, rope, string

Why it matters

Correct line size and neat winding prevent tangles, reduce vibration, and help the head feed line properly. This model advances line automatically; tapping the head on the ground can break parts and cause the head to malfunction.

For the Craftsman weed trimmer model 358795540, 0.080-inch line is the better choice because the manual specifies 0.080 in (2 mm) round line for proper automatic line advance and safe cutting performance. Using 0.095-inch line can prevent the head from feeding correctly.

What we recommend for model 358795540

Use the line size and type the trimmer was designed around:

• Use 0.080-inch (2 mm) round trimmer line
• Avoid thicker line (like 0.095) because it can jam or stop auto-advance
• Never use wire, rope, or string; those can break and become dangerous projectiles
• Keep the shield installed and the cutting line at the proper length

For the exact operating and safety guidance, follow the 358795540 owner's manual.

0.080 vs 0.095: quick comparison

Feature	0.080-inch line	0.095-inch line
Best use	General trimming and edging	Heavy weeds (on trimmers designed for it)
Feed/advance on 358795540	Designed to advance correctly	Can fail to advance or bind
Cutting feel	Lighter, smoother	More drag, higher load
Risk on this model	Low when round line is used	Higher risk of head malfunction

Why it matters

This Craftsman trimmer uses an automatic line advance system. When the line is too thick or the wrong shape, it may not feed properly, which leads to poor cutting, extra vibration, and avoidable wear on the trimmer head.

If you want longer line life without going thicker

Instead of moving up to 0.095, we recommend these adjustments:

• Use minimum throttle needed and do not “crowd” the line into hard objects
• Trim away from rocks, gravel, and fence posts to reduce line breakage
• Clean debris from the head so the line can move freely
• Replace cracked or damaged head components before using the trimmer
