How to remove the motor casing?

Disassembling the trimmer head on the Ryobi P2008 (2018) is a straightforward task. First, remove the battery. To access the spool or remove the head, align the notch on the trimmer head with the small hole on the gear case, insert a locking pin or a small screwdriver to lock the shaft, and turn the head clockwise (it has a reverse thread).

Step-by-Step Breakdown

1. Removing the Spool Cover (For quick string replacement)

You do not need to unscrew the entire head just to reload the trimmer line.

• Locate the tabs: Find the two release tabs on the sides of the trimmer head. They are often marked with embossed arrows.
• Press and pull: Press both tabs in and up simultaneously, then pull the spool cover off to expose the internal spool.

2. Removing the Trimmer Head (For replacement or clearing jams)

If you need to replace the entire bump head assembly, you will need to unthread it from the drive shaft.

• Lock the drive shaft: Rotate the head until the internal metal slot aligns with the small hole on the shaft casing.
• Insert the pin: Push a metal pin, nail, or small screwdriver completely into the hole to prevent the shaft from spinning.
• Unthread: While holding the locking tool in place, twist the trimmer head clockwise. Remember, trimmer heads use left-handed threads (lefty-tighty, righty-loosey).

3. Disassembling the Upper Components (Motor Cover & Housing)

If you are doing deeper repairs like replacing the motor, handle, or wiring, you will need to access the upper housing.

• Remove the pivot assembly bolts: Locate the screws around the lower pole and the pivot hinge.
• Remove the handle: Unscrew and remove the adjustable auxiliary handle.
• Slide off covers: Carefully pry or slide the plastic motor housing halves apart by unfastening the remaining screws holding the clamshell together
