LINE REPLACEMENT

NOTICE: Always use the recommended nylon

cutting line with a diameter that does not exceed

0.120 in. (3.0 mm). Using line other than that

specied may cause the tool to overheat or become

damaged.

WARNING: Never use metal-reinforced line,

wire, or rope, etc. These can break off and become

dangerous projectiles.

1. Remove the power plug or battery pack.

2. Remove the remaining cutting line, if

necessary. Simply pull it out by hand.

3. Cut one piece of cutting line 26 ft. (8m) long.

Insert the line into the eyelet (Fig.5) and

push the line until the end of the line comes

out of the opposite eyelet. Pull the line from

the other side until equal lengths of the line

appear on both sides of the trimmer head.

4. Press and rotate lower cover assembly in the

direction indicated by the arrow to wind the

cutting line onto the spool (Fig. 6).

5. Push down on the trimmer head while

pulling on the lines to manually advance the

line in order to check for proper assembly of the cutting line.

When the cutting line breaks from the eyelet or the cutting line is not released when the trimmer head is

tapped, follow the steps below:

1. Remove the power plug from the string trimmer.

2. Press two release tabs on the trimmer head and remove the lower cover assembly of the trimmer

head by pulling it straight out (Fig. 7a & 7b).

3. Remove the cutting line from the spool.

4. Make sure the spring is in its original

position in the lower cover assembly.

5. With one hand holding the trimmer, use

another hand to grasp the lower cover

assembly and align the slots in the lower

cover assembly with the release tabs. Press

the lower cover assembly until it snaps into

place, at which time you will hear a distinct click sound (Fig. 8).

6. Following the instructions in “LINE REPLACEMENT” to reload the cutting line.

WARNING: Make sure that the release tabs on the spool retainer snap into place or the spool

assembly will come out during operation, which may result in serious personal injury.

This document describes the EGO POWER+ Replacement String Trimmer Head, Model Number AH3810, a component designed for various EGO POWER+ string trimmers and multi-tool attachments.

Function Description:

The EGO POWER+ Replacement String Trimmer Head is an essential part of the string trimmer system, responsible for holding and dispensing the cutting line. It facilitates the trimming of grass and weeds by rotating the cutting line at high speeds. This replacement head ensures continued functionality of your EGO POWER+ trimming tools when the original head is damaged or worn.

Compatibility:

This replacement string trimmer head is exclusively compatible with the following EGO POWER+ tools:

EGO POWER+ String Trimmer STX3800
EGO POWER+ String Trimmer ST1530/ST1530-FC
EGO POWER+ Brush Cutter BCX3800
EGO POWER+ Brush Cutter BC3800/BC3800-FC
EGO POWER+ Multi-tool String Trimmer Attachment STA1500/STA1500-FC

Important Safety Information:

DANGER: If the head loosens after it is fixed in position, replace it immediately. Never use a trimmer with a loose cutting attachment. Replace a cracked, damaged, or worn cutting head immediately, even if the damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious injury.
WARNING: Always remove the power plug or battery pack from the product when you are assembling parts, making adjustments, cleaning, or when the product is not in use.

Technical Specifications:

Recommended Cutting Line: Nylon line with a diameter not exceeding 0.120 inches (3.0 mm). Using a line of a different diameter than specified may cause the tool to overheat or become damaged.
Cutting Line Length for Replacement: 26 feet (8 m).

Usage Features:

Removing the Trimmer Head:

Remove the power plug or battery pack.
Rotate the trimmer head to align the slot in the flange with the shaft locking hole in the gear case.
Insert the provided Allen key into the aligned holes to act as a stabilizer.
Wearing gloves, loosen the cutting head COUNTER-CLOCKWISE (Fig. 2) until it can be removed from the shaft.

Installing the New Trimmer Head:

Before installing the new trimmer head, make sure that the flange is located on the drive shaft with the bulge facing away from the gear case, and that the flange cover is closely against the flange with its flat surface facing outward (Fig. 3).
Take out the new trimmer head and open it. Align the drive shaft with the screw hole of the trimmer head and then tighten the trimmer head onto the shaft COUNTER-CLOCKWISE.
Rotate the trimmer head to align the slot in the flange with the shaft locking hole in the gear case and insert the provided Allen key into the aligned holes to act as a stabilizer.
Wearing gloves, tighten the trimmer head firmly on the shaft COUNTER-CLOCKWISE (Fig. 4).

Line Replacement:

NOTICE: Always use the recommended nylon cutting line with a diameter that does not exceed 0.120 inches (3.0 mm). Using a line of a different diameter than specified may cause the tool to overheat or become damaged.
WARNING: Never use metal-reinforced line, wire, or rope, etc. These can break and become dangerous projectiles.

Remove the power plug or battery pack.
Remove any remaining cutting line, if necessary. Simply pull it out by hand.
Cut a piece of cutting line 26 feet (8 m) long. Insert the line into the eyelet (Fig. 5) and push the line until the end of the line comes out of the opposite eyelet. Pull the line from the other side until equal lengths of the line appear on both sides of the trimmer head.
Press and rotate the lower cover assembly in the direction indicated by the arrow to wind the cutting line onto the spool (Fig. 6).
Push down on the trimmer head while pulling on the lines to manually advance the line and to check for proper assembly of the cutting line.

Troubleshooting Line Issues (Line breaks or does not release):

When the cutting line breaks out of the eyelet or the cutting line is not released when the trimmer head is tapped, follow the steps below:

Remove the power plug from the string trimmer.
Press the two release tabs on the trimmer head and remove the lower cover assembly of the trimmer head by pulling it straight out (Fig. 7a & 7b).
Remove the cutting line from the spool.
Make sure the spring is in its original position in the lower cover assembly.
With one hand holding the trimmer, use the other hand to grasp the lower cover assembly and align the slots in the lower cover assembly with the release tabs. Press the lower cover assembly until it snaps into place, at which time you will hear a distinct click sound (Fig. 8).
Follow the instructions in "LINE REPLACEMENT" to reload the cutting line.

WARNING: Make sure that the release tabs in the spool retainer snap into place in the correct position; otherwise, the spool assembly may detach during operation, which may result in serious personal injury.

Maintenance Features:

The document primarily focuses on replacement and line loading, implying that the head itself is a replaceable unit rather than one requiring extensive internal maintenance. Regular inspection for cracks, damage, or wear is crucial for timely replacement.
