Husqvarna 330LK String Trimmer

The Husqvarna 330LK is a professional gas string trimmer with a detachable shaft, so the same power head can run trimmer, edger, and pole saw attachments. For tree and landscape crews it is one engine that covers a lot of jobsite cleanup.

One engine, several tools

The LK in 330LK means loop handle and combi shaft. Pull the lower shaft and you can swap the trimmer head for other Husqvarna combi attachments, such as an edger, hedge trimmer, or pole saw. On a tree crew, that means one power head in the truck can trim around a stump site, edge a bed after a removal, and take small limbs off a low branch with a pole saw attachment.

The split shaft also makes the unit easier to store and transport. It fits in a truck box or trailer rack that would not take a full-length straight-shaft trimmer.

The 330LK is the more powerful of Husqvarna's two common combi units. That extra power helps when you run heavier attachments, such as a pole saw in hardwood or a brushcutter blade in thick growth, where a lighter engine can bog. Searches for 330LK Husqvarna and Husqvarna 330LK weed eater point to the same machine.

Choosing attachments

Husqvarna attachments in its combi line share the same coupling, so check the attachment's compatibility list before buying. The most common add-ons for tree work are the pole saw for limbing and clearance, and the edger for cleanup around hardscape after stump grinding. Brushcutter blades, where approved, help clear heavy weeds and saplings on overgrown sites.

Add attachments one at a time as the work calls for them. The point of a combi system is to cover more jobs without buying separate engines, not to carry every attachment on every job.

A pole saw attachment on a gas power head is a good fit for clearance pruning along driveways and sidewalks, where you can reach limbs from the ground without a climber. Keep in mind that a pole saw on a combi unit adds weight at the end of a long shaft, so take breaks and keep a good stance. Never use a pole saw near power lines; follow ANSI Z133 approach distances.

Running and maintaining it

Use fresh fuel mixed at the ratio in the operator's manual, and drain or stabilize fuel if the unit will sit. Clean the air filter regularly on dusty jobs, check the spark plug at the start of the season, and keep the shaft coupling clean so attachments seat fully.

Wear eye protection, hearing protection, long pants, and sturdy boots. Keep bystanders well back, since a trimmer throws debris farther than most people expect. Compare it with the Husqvarna 525LK if you want a lighter combi unit.

At the end of the day, clean grass and debris from the trimmer head, the guard, and the engine cooling fins. Check the gearhead grease at the intervals in the manual and tighten any loose fasteners. A few minutes of care keeps the unit starting easily and running at full power.
