Frequently asked questions

What attachments are compatible with the Husqvarna 330LK?

The Husqvarna 330LK is a combi-trimmer featuring a universal click-on attachment system. It is compatible with over 15 Husqvarna attachments, including the PA310 pole saw, HA322 hedge trimmer, ECA308 edger, BA101 blower, and various brushcutter attachments. Check out the selection here: https://www.husqvarna.com/us/trimmer-attachments/

Is the Husqvarna 330LK a 2-cycle or 4-cycle trimmer?

The Husqvarna 330LK is equipped with a 28cc 2-cycle (2-stroke) gas engine. Because it is a 2-cycle engine, it requires a pre-mixed fuel and oil blend at a 50:1 ratio to operate correctly and avoid engine damage.

What size trimmer line does the Husqvarna 330LK use?

The Husqvarna 330LK typically uses a 0.095-inch diameter trimmer line, which is ideal for heavy-duty residential trimming and thick vegetation. We recommend using Husqvarna Titanium Force® or TrimForce™ line for the best cutting performance.

How does the Effortless Starting™ system work?

The Effortless Starting™ system on the Husqvarna 330LK uses a spring-assisted starter combined with Air Purge technology to remove air from the carburetor. This specialized design reduces the pull cord resistance by up to 30%, making the trimmer much easier and faster to start with minimal physical effort.

How do I adjust the cutting width on the 330LK?

The Husqvarna 330LK features a class-leading 20-inch cutting path for clearing large areas quickly. However, the cutting guard can be adjusted to an 18-inch path, which concentrates the engine's power to help you cut through thicker, denser vegetation with ease. Remove the 2 screws holding the trimmer line cutter on the guard. Then, rotate the cutter to its alternate position, and reinstall and tighten the 2 screws.

Is the shaft on the Husqvarna 330LK straight or curved?

The Husqvarna 330LK features a straight shaft design that is attachment capable. Straight shafts offer an extended reach, making it easier to trim under bushes, shrubs, and fences, and generally provide better ergonomics for taller users.

How heavy is the Husqvarna 330LK?

The Husqvarna 330LK weighs 12.85 lbs (excluding the cutting equipment). To make this weight comfortable during extended use, the trimmer features a balanced design and LowVib® technology, which uses dampeners to significantly reduce engine and chassis vibrations.

Does the Husqvarna 330LK come with a shoulder strap or harness?

No, a harness or shoulder strap is not included in the box with the 330LK combi-trimmer. However, compatible Husqvarna harnesses can be purchased separately to help distribute the weight for longer landscaping jobs.

How do I reload the string on the 330LK trimmer?

The 330LK is equipped with the high-capacity RapidReplace™ Trimmer Head, which is designed for easy and quick line reloads. You simply align the arrows on the head, feed the trimmer line straight through, and twist the bump knob to wind the line—no disassembling of the head is required.

What is the difference between a dedicated string trimmer and a combi-trimmer like the 330LK?

A dedicated string trimmer features a solid shaft and is built solely for trimming grass and weeds. The Husqvarna 330LK is a combi-trimmer, meaning its lower shaft can be detached. This allows you to swap out the trimmer head for other tools, turning one engine into a multi-purpose machine for edging, blowing, pruning, and hedge clipping.

What is Ethanol Free Gas & Where to Find it Near Me

Ethanol fuel, a gas additive, is everywhere! Nowadays, the gas you pump from almost every gas station contains a blend of gasoline and ethanol. The percentage of ethanol blend is indicated by the E number. For example E10 means the gas mixture contains 90% gas and 10% ethanol. In automobiles, ethanol fuel won’t do much harm to your car's engine. However, when you're using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
