Description
Overview:
This Genuine Husqvarna throttle lockout (MPN 588137701 / 588 13 77-01) is a safety-critical control designed for Husqvarna petrol disc cutters. Made from durable, impact-resistant polymer in Husqvarna orange, it is built to handle vibration, dust, and frequent use on site. The lockout prevents accidental throttle engagement, so the engine can only rev when the operator deliberately actuates the throttle in the correct sequence. This helps protect the user and the machine during starting, handling, and blade positioning. Engineered by Husqvarna for a precise fit and smooth action, it restores factory-safe operation on compatible saws, including the K 770 and K 760 variants. Ideal as a like-for-like replacement when the original part becomes worn, damaged, or sticky.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and performance
- Designed to prevent accidental throttle engagement for safer operation
- Hard-wearing polymer resists site abrasion, impacts, and fuel/oil exposure
- Accurate fitment on specified models; no modifications required
- Smooth actuation and positive return for consistent control
- Colour-matched Husqvarna orange for easy identification during maintenance
- Helps maintain compliance with site safety practices
- Simple to replace with standard hand tools, reducing downtime
- Reliable performance in dusty, wet, and high-vibration conditions
- Replaces worn components to restore the saw's original safety function
Typical Applications:
Used on handheld disc cutters in construction, utilities, roadworks, landscaping, and demolition. Essential when cutting concrete, masonry, asphalt, or metal, especially where precise handling is required at start-up, during repositioning, or while moving between cuts. Also suitable for emergency services variants that demand dependable, predictable control in demanding environments.
Also known as:
Throttle safety, engine lock, cutter throttle control, trigger lock, lock-off, dead-man lock. These terms refer to the same safety control that prevents unintended throttle application and helps ensure the machine only accelerates when the operator deliberately commands it.
