Q: How do I activate the choke to start the Husqvarna 333R Mark II brushcutter?

The choke of the Husqvarna 333R Mark II is a two-position control that regulates the enrichment of the fuel mixture at startup. Here’s how to use it: Cold Start Set the stop switch to the start position Press the fuel pump 10 times to pre-fill the circuit Move the choke control to the choke (closed) position - refer to figure 13 in the manual Slowly pull the starter cord until you feel resistance, then pull quickly until the engine stutters for the first time Open the choke by placing the control in the run (open) position - figure 14 Continue to operate the starter until the engine starts completely Let the engine warm up for 60 seconds at low speed before use Hot Start If the engine is already warm, set the choke directly to the run position and operate the starter without closing the choke. Tip: Never force the starter cord. If you feel too much resistance after the first stutter, it means the engine is starting to catch - do not insist, open the choke and gently restart.

Q: How to adjust the idle on a HUSQVARNA 129R?

On the HUSQVARNA 129R, the idle is adjusted via the T screw of the carburetor . The correct idle speed should be between 2,800 and 3,200 rpm , and at this setting, the cutting equipment should not be running. Adjustment Procedure: Turn the T screw clockwise to increase the idle Turn the T screw counterclockwise to decrease the idle Before fine-tuning, first perform a coarse adjustment: turn the T screw clockwise until the equipment starts to run, then turn it counterclockwise until it stops completely. A well-adjusted speed allows the engine to run smoothly in all positions. If the cutting equipment still runs at idle after adjustment, turn the T screw counterclockwise until it stops completely. If the problem persists, contact an authorized workshop, as fine adjustment of the carburetor should be performed by a qualified technician.

Q: What length of cutting line should be used for the 553RBX?

According to the Husqvarna 553RBX manual, you should reduce the length of the cutting line to 10 to 12 cm when mowing to minimize damage to plants and optimize the operation of the trimmer. The manual does not specify the initial total length of the line on the spool. This depends on the cutting head used: T35 / T35X / S35 : line diameter 2.4 to 3.0 mm T45X : line diameter 2.7 to 3.3 mm S II : head compatible with specific heads To extend the life of your line, it is recommended to soak it in water for a few days before use .

Question 7

How to adjust the idle on a HUSQVARNA 129R?

Accepted Answer

On the HUSQVARNA 129R, the idle is adjusted via the T screw of the carburetor. The correct idle speed should be between 2,800 and 3,200 rpm, and at this setting, the cutting equipment should not be running.

Adjustment Procedure:

Turn the T screw clockwise to increase the idle
Turn the T screw counterclockwise to decrease the idle

Before fine-tuning, first perform a coarse adjustment: turn the T screw clockwise until the equipment starts to run, then turn it counterclockwise until it stops completely. A well-adjusted speed allows the engine to run smoothly in all positions.

If the cutting equipment still runs at idle after adjustment, turn the T screw counterclockwise until it stops completely. If the problem persists, contact an authorized workshop, as fine adjustment of the carburetor should be performed by a qualified technician.

Question 8

What length of cutting line should be used for the 553RBX?

Question 10

What fuel and oil mixture for my Husqvarna 122C?

Accepted Answer

For your Husqvarna 122C, you must use unleaded gasoline with a minimum quality of 90 RON (octane rating). E10 fuel (containing up to 10% ethanol) is acceptable. This machine has a catalytic converter, which is why unleaded gasoline is mandatory to avoid damaging it.

Mixing ratio: 1:50 (2%) – that is, 2 liters of 2-stroke oil for 100 liters of gasoline. Here are the exact proportions according to the amount of fuel to prepare:

5 liters of gasoline + 0.10 liter of oil
10 liters of gasoline + 0.20 liter of oil
15 liters of gasoline + 0.30 liter of oil
20 liters of gasoline + 0.40 liter of oil

Only use HUSQVARNA 2-stroke engine oil specially formulated for air-cooled engines. Never use 4-stroke engine oil or water-cooled oil (outboard): this would destroy the engine and could damage the catalytic converter.

Preparing the mixture: first pour half of the gasoline into a clean can, add all the oil, shake vigorously to mix well, then pour in the rest of the gasoline and mix again. Shake the can one last time before filling the trimmer's tank.

Storage: do not prepare more than a month's worth of consumption at a time. The mixture loses effectiveness over time. Your 122C's tank has a capacity of 0.3 liters, which means you should only prepare small amounts in advance.
