Question 1

How to remove the grass suction turbine from the HUSQVARNA ROYAL 43 S mower?

Accepted Answer

Before you begin: Make sure the HUSQVARNA ROYAL 43 S mower is turned off and cold. Disconnect the spark plug wire to prevent any accidental starting during the procedure. Wait a few minutes for the engine to cool completely before starting the disassembly.

Accessing the suction turbine: The grass suction turbine of your ROYAL 43 S is accessible from underneath the casing. Lay the mower on its side with the exhaust facing up to prevent gasoline from leaking from the tank. Ensure that all grass and debris accumulated under the casing are cleared with a soft brush before starting the disassembly.

Removing the casing: Locate all the screws or bolts that secure the lower casing under the mower. Use a screwdriver or wrench suitable for the size of the screws (usually standard screws). Slowly and methodically unscrew all the fasteners, placing them in a safe location to avoid losing them. Be careful not to force the screws or the casing to avoid damaging the plastic or metal parts.

Disassembling the turbine: Once the casing is removed, you have access to the suction turbine. It is secured with screws or bolts depending on your model's configuration. Precisely locate the fastening points of the turbine to its rotation axis. Gently unscrew these fasteners using the appropriate tool. Carefully remove the turbine by guiding it gently out of its housing to avoid snagging or damaging it, as well as adjacent parts.

After removal: Take advantage of the disassembly to carefully inspect the condition of the turbine. Check for cracks, deformations, wear, or debris blockages. Clean the turbine housing and all adjacent parts with a soft brush to remove accumulated grass and dust residues. If the turbine is damaged or worn, replace it with an original part specific to your model (HUSQVARNA ROYAL 43 S turbine reference available from an authorized dealer). For reassembly, perform the reverse operation by carefully locating each removed element.

Maintenance tip: To keep the turbine in good working condition, it is recommended to clean it regularly, especially after prolonged use in tall, dry grass or in dusty conditions. Regular maintenance prevents debris buildup and ensures optimal suction of the grass collection bag.

Question 2

How do I adjust the chain oil flow on a Husqvarna 445 chainsaw?

Accepted Answer

To adjust the chain oil flow on your Husqvarna 445 chainsaw, follow these steps:

1. Preparation

Ensure that the chainsaw is turned off and placed on a stable surface.

2. Locating the oil reservoir

The oil reservoir is usually located on the side of the chainsaw, identifiable by a cap marked with an oil symbol.

3. Identifying the oil flow adjustment

On the Husqvarna 445 model, the oil flow is adjustable via a screw or lever located near the chain case or oil reservoir.

4. Adjusting the flow

Use a suitable screwdriver to turn the adjustment screw:

Turning clockwise increases the oil flow.
Turning counterclockwise decreases the flow.

5. Checking the adjustment

Start the chainsaw and let it run at idle.
Observe the rotating chain: a sufficient amount of oil should be visible to ensure proper lubrication.
If necessary, readjust the flow until optimal flow is achieved.

6. Safety

Once the adjustment is complete, ensure that the screw or lever is securely fastened to prevent loosening during use.

Proper adjustment of the oil flow is essential to extend the life of the chain and ensure effective and safe cutting.
