ECHO Chainsaw CS-2511TES Throttle Lockout Lever - Replacement Part

ECHO CS-2511TES Throttle Lockout Lever

I designed this replacement throttle lockout lever for the ECHO CS-2511TES chainsaw, using the original factory component as a reference.

The model was recreated to match the original part's shape, mounting points, and mechanical operation as closely as possible.

In the photos, you can see the original orange component next to my red 3D-printed replacement.

Part Information

• Chainsaw: ECHO CS-2511TES

• Part: Throttle Lockout Lever

• Original Part Number: C460-000590

• Type: Functional replacement part

• Design: Recreated from the original component

Recommended Printing Settings

I recommend printing this part using PETG for its mechanical strength, durability, and better heat resistance compared to PLA.

The following settings were used for my print:

• Material: PETG

• Layer height: 0.16 mm

• First layer height: 0.24 mm

• Perimeters: 6

• Top solid layers: 8

• Bottom solid layers: 8

• Infill: 30%

• Infill pattern: Gyroid

• Supports: Enabled, auto-generated

• Support style: Snug

• Overhang threshold: 55°

• Top support contact distance: 0.2 mm

• Bottom support contact distance: 0.3 mm

• Support interface layers: 4 top, 3 bottom

• Support interface spacing: 0.18 mm

Supports are recommended, particularly around the mounting points and overhanging sections. Proper support placement helps maintain dimensional accuracy and improves the quality of smaller mechanical features.

For the best results, pay attention to print orientation and layer adhesion, especially around the pivot hole and narrow sections of the lever.

Installation and Fitment

Before installation, compare the printed component with the original part and verify that the mounting points and moving sections fit correctly.

Depending on your printer calibration and material shrinkage, minor adjustments or cleaning of the printed part may be necessary.

Important Safety Notice

This is a functional 3D-printed replacement, not just a visual replica. The part has been recreated to match the original throttle lockout lever's shape, fit, and mechanical operation, allowing it to perform its intended function within the throttle mechanism.

However, this component is part of the chainsaw's throttle safety mechanism. The replacement is independently designed and has not been certified or approved by ECHO.

Although PETG provides good mechanical strength and durability, any 3D-printed component can fail under repeated stress, vibration, heat, or prolonged use. Being functional does not guarantee the same level of safety or long-term reliability as the original manufacturer part.

For maximum safety, I recommend using a genuine manufacturer-approved replacement whenever possible.

This model is shared as a practical replacement design for personal projects, repairs, experimentation, and educational purposes. Anyone choosing to use it does so at their own discretion and should carefully inspect the part and verify its mechanical operation before installation.

For Users in Serbia

If you are located in Serbia and need this replacement part but don't have access to a 3D printer, feel free to contact me directly on Facebook.

I can print the part for you using PETG.
