This document provides essential information for the safe and efficient operation of the Husqvarna 125B and 125BVX leaf blowers. Always read the safety chapter before assembly or operation.
Assembly
The blower tube and nozzle must be attached to the blower outlet. Ensure the bolt is sufficiently loose before inserting the tube, then tighten it clockwise. For vacuum models (125BVX), the collection bag and vacuum tubes must be assembled and attached according to the specific steps provided in the manual.
Operation
This product features a two-cycle engine requiring a 50:1 gasoline-to-oil mixture. Use high-quality two-cycle engine oil and unleaded gasoline with at least 90 RON (87 AKI) octane rating. Do not use gasoline with more than 10% ethanol (E10).
Starting the engine
- Fill the fuel tank with a clean fuel mixture.
- Push the primer bulb 10 times.
- Move the choke control to the FULL CHOKE (closed) position.
- Move the variable speed control fully counterclockwise.
- Hold the machine on the ground and pull the starter rope handle until the engine attempts to start (max 3 times).
- Move the choke control to the 1/2 position and pull the starter rope until the engine starts.
- Run for 10 seconds, then move the choke to the OFF CHOKE (open) position.
Maintenance
Regular maintenance is crucial for product longevity and safety. Daily tasks include cleaning external surfaces, checking throttle and speed control, and inspecting the air filter. Weekly tasks involve checking the starter device, spark plug electrode gap (0.6 mm), and cleaning the spark arrester screen. Yearly maintenance includes a full inspection of the spark plug, fuel filter, and cooling system.
Safety
Always wear approved personal protective equipment, including eye, ear, and respiratory protection. Maintain a safe distance of at least 15 meters from other people or animals. Do not operate the product in poorly ventilated areas to avoid carbon monoxide poisoning.
