Throttle Cable Function
The 512699701 serves as the mechanical connection between the blower's throttle control and engine throttle mechanism.
A simplified control path is:
Throttle Lever → 512699701 Control Cable → Throttle Arm / Carburetor → Engine Speed
When the operator moves the throttle lever, the cable transfers that mechanical movement to the throttle mechanism. This changes the engine's operating speed and, consequently, the blower's airflow output.
The cable therefore plays an important role in providing predictable throttle response.
Husqvarna 150BT Application
The Husqvarna 150BT backpack blower is a documented application for 512699701. Available model cross-reference information lists both the 150BT and applicable 150BT production configurations as using this throttle cable.
Because equipment can undergo production revisions while retaining the same general model name, verify the complete model and product information before ordering.
Handle & Control System
On compatible blowers, the throttle control is incorporated into the operator handle.
Official illustrated parts documentation places 512699701 within an assembly containing components such as the:
- Throttle lever
- Control lever
- Handle case
- Handle cover
- Switch
- Springs
- Control cords
- Cable
- Tube and mounting hardware
This confirms that 512699701 functions within the blower's operator-control system.
Engine Speed Control
The throttle cable allows the operator to control engine speed from the blower handle.
As the throttle control is moved, the inner cable travels within its outer housing and operates the corresponding throttle mechanism.
Proper cable movement is important for:
- Smooth throttle response
- Full engine-speed range
- Reliable throttle return
- Predictable blower output
- Operator control
A cable that binds inside its housing can interfere with normal throttle operation.
Common Reasons for Replacement
Replacement of the 512699701 Throttle Cable may be appropriate if the original cable has:
- Broken
- Frayed
- Stretched
- Become kinked
- Developed corrosion
- Become difficult to move
- Seized inside the cable housing
- Developed damaged cable ends
- Become disconnected
- Developed excessive slack
- Sustained handle damage
- Become unable to move the throttle arm correctly
A stretched cable may still appear intact while failing to provide the full range of throttle movement.
Possible Signs of Cable Wear
A worn or damaged throttle cable may contribute to:
- Engine not accelerating correctly
- Reduced maximum engine speed
- Delayed throttle response
- Throttle lever moving without corresponding engine response
- Throttle control feeling unusually stiff
- Throttle lever becoming difficult to move
- Engine remaining at one speed
- Excessive throttle-control play
- Cable not moving freely
- Visible fraying or damage
Published repair information specifically identifies failure of the throttle-body arm to move when the throttle lever is operated, or the cable wire failing to move freely, as common reasons for replacing 512699701.
Cable Stretch
Throttle cables can gradually stretch through repeated use.
Excessive stretching can introduce unwanted slack into the control system.
Possible symptoms include:
- Reduced throttle travel
- Poor acceleration
- Inability to reach full engine speed
- Excessive movement at the throttle lever
- Delayed engine response
Replacement of the worn cable can restore the original mechanical connection when cable stretch is the source of the problem.
Cable Housing Inspection
Inspect the outer cable housing for:
- Cracks
- Cuts
- Crushing
- Kinks
- Heat damage
- Abrasion
- Severe bending
- Loose mounting points
Damage to the outer housing can interfere with movement of the inner cable even if the cable itself has not broken.
Throttle Lever Inspection
Whenever replacing 512699701, inspect the throttle lever and handle-control assembly.
Check for:
- Cracking
- Excessive play
- Damaged cable attachment points
- Binding
- Broken springs
- Loose hardware
- Damaged pivot points
Official parts documentation shows the cable operating alongside several dedicated handle-control components, so problems elsewhere in the assembly can sometimes produce symptoms similar to cable failure.
Throttle Arm Inspection
Inspect the throttle mechanism where the opposite end of the cable connects.
Check for:
- Binding
- Excessive dirt
- Damaged linkage
- Corrosion
- Bent components
- Damaged cable attachment points
- Restricted movement
A replacement cable cannot correct a seized or damaged throttle mechanism.
Cable Routing
Correct routing is particularly important with backpack blower throttle cables.
The cable must accommodate movement between the:
Operator Handle → Blower Tube → Engine / Throttle Assembly
Improper routing can result in:
- Cable binding
- Sharp bends
- Restricted throttle movement
- Premature cable wear
- Cable abrasion
- Insufficient throttle travel
Before removing the original cable, note its complete routing through the blower assembly.
Installation Considerations
Before replacing 512699701:
- Shut off the blower completely.
- Allow the engine and exhaust system to cool.
- Disconnect the spark plug to prevent accidental starting.
- Note the existing throttle cable routing.
- Photograph the routing and connection points if helpful.
- Open the applicable throttle-control handle housing.
- Disconnect the cable from the throttle lever.
- Follow the cable toward the engine.
- Release applicable cable retainers or guides.
- Disconnect the cable from the engine throttle mechanism.
- Remove the original cable.
- Inspect the throttle lever and throttle arm.
- Route the new 512699701 Cable along the original path.
- Connect the cable to the engine throttle mechanism.
- Connect the opposite end to the throttle control.
- Secure the cable in its applicable guides and retainers.
- Verify smooth throttle movement.
- Confirm that the throttle returns correctly.
- Reassemble the control housing.
- Test engine-speed control before returning the blower to regular use.
Installation Tips
During installation:
- Photograph the original cable routing before removal
- Avoid sharp bends in the replacement cable
- Do not kink the cable housing
- Make sure both cable ends are fully engaged
- Route the cable away from hot exhaust components
- Keep the cable away from unintended moving parts
- Verify that the handle control moves freely
- Check full throttle travel before starting the engine
- Make sure the cable is secured in its original guides
- Do not force the inner cable if movement feels restricted
- Investigate binding before operating the blower
Previous Part Numbers
The 512699701 replaces earlier cable references in applicable equipment.

Replacement information identifies these earlier numbers as superseded by 512699701 for compatible applications.
Always verify compatibility with the exact equipment model before ordering based solely on an older part number.
Maintenance Tips
To help maintain reliable throttle operation:
- Inspect the cable periodically for wear
- Avoid excessively sharp cable bends
- Keep the cable away from hot engine components
- Check handle-control movement regularly
- Investigate a stiff throttle lever promptly
- Keep the cable properly routed and supported
- Inspect attachment points for damage
- Replace frayed or severely kinked cables
- Check the throttle mechanism if cable movement becomes restricted
- Avoid operating the blower with a damaged throttle-control system
