Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact tolerances, ensuring the knob engages and rotates with the same tactile response and mechanical precision as the original component.
- Direct-Replacement Fit — This assembly installs directly in place of the original, using the same mounting interface with no reworking or adaptation of the surrounding hardware.
- Broad Husqvarna Compatibility — Fits PP440HF, PP440, PP480HF, PP480, PP492 power packs; WS220, WS440HF, WS482HF wall saws; and PG680RC, PG690RC, PG820RC, PG830RC floor grinders.
- Accurate Operator Control — A correctly functioning turning knob delivers precise, repeatable adjustments so operators can set and maintain the right output or position settings with confidence.
- Multi-Machine Value — One part number covering power packs, wall saws, and floor grinders makes this assembly a practical solution for crews running mixed Husqvarna Construction equipment.
The Turning Knob Assembly is an operator-interface control component that allows the user to make rotational adjustments to machine settings — such as output level, flow control, or positioning — depending on the host machine. A worn, cracked, or missing turning knob makes accurate adjustment difficult or impossible, forcing operators to guess at settings and increasing the risk of incorrect machine output. Replacing a damaged knob assembly with this genuine OEM part restores full, confident control over the machine's operating parameters.
