Removing the spool cap and bump knob

To remove the spool cap and bump knob from your Toro trimmer, start by releasing the throttle trigger and switching the "On/Off" toggle switch to the "Off" position. Lay the trimmer on a flat surface and remove the spark plug boot from the spark plug, allowing the engine to cool completely.

Now, you can focus on the bump knob. If you have a straight shaft trimmer, turn the bump knob to the right to remove it. Hold the large part of the head with a pair of pliers to keep it from turning, and then use another pair of pliers to grab the bump knob and turn it off. If the bolt inside the bump knob doesn't turn with it, you may need to use a hacksaw to cut through the plastic of the knob to access the bolt.

Once the bump knob is removed, you can access the spool. Remove the spool cap by pressing the tabs or unscrewing it. Pull out any old remnants of the trimmer line, being careful not to lose the spring located underneath. Take note of the spring's position so that you can reinstall it later.

At this point, you have successfully removed the spool cap and bump knob, and you can now proceed with replacing the trimmer line.

Inserting the line into the anchor hole

To insert the line into the anchor hole, follow these steps:

First, remove the bump knob from the bottom of the trimmer by screwing it off. You may need a large pair of pliers to hold the head and prevent it from turning while you use another pair to turn the knob. If the knob turns but the bolt inside doesn't, you may need to use a hacksaw to cut through the plastic of the knob. Once the knob is removed, carefully pull out the spool, being mindful not to lose the spring located underneath. Take note of the spring's position for reassembly.

With the spool removed, cut a new line piece, usually between 10 to 25 feet in length, depending on your model. Now, insert one end of the new line into the anchor hole inside the spool. Ensure you're using the correct hole, as some spools have two holes towards the inside. Do not insert the line more than 1/4" into the spool.

At this point, you should be holding the spool in your left hand and the line in your right hand. Take both pieces of the line in your right hand and place them on separate sides of one of your fingers to prevent tangling. Now, carefully wind the line onto the spool. Ensure you wind the line in the direction indicated on the spool, and do not twist the two lines, or the line will not feed out when you use the trimmer.

Once the line is fully wound, secure each end in the slots provided on the spool, typically at the 6 o'clock and 12 o'clock positions. Now, you can reinstall the spring and push each end of the line, while still secured in the slots, into the eyelets of the outer casing of the trimmer head.

Winding the line onto the spool

To wind the line onto the spool, start by removing the bump knob from the bottom of the trimmer by screwing it off. You may need a large pair of pliers to hold the head and prevent it from turning while you use another pair of pliers to turn the bump knob. If the knob turns but the bolt doesn't, you may need to use a hacksaw to cut the plastic of the knob. Once the knob is removed, pull out the spool, taking care not to lose the spring located underneath. Take note of the position of the spring so you can reinstall it later.

Take the spool in your hand and look for two holes on the inside. Cut a new line, usually between 10 and 15 feet in length, and push one end of the line into each hole, inserting it no more than 1/4" into the spool. Hold the spool in your left hand and the two pieces of line in your right hand, keeping them on either side of your finger to prevent tangling.

Now, turn the spool in your left hand towards you, pulling the line between your fingers without twisting it. Wind all of the lines onto the spool, securing each end in the slots at the 6 and 12 o'clock positions. Install the spring and push each end of the line, while still secured in the slots, into the eyelets of the outer casing of the head.

Finally, push the spool into the casing and onto the spring. Tug on each of the lines to release them from the slots, and reinstall the bump knob.

Replacing the spool cap

To replace the spool cap of a Toro electric trimmer, you must first remove the old spool cap. This can be done by pressing tabs or unscrewing the spool cap. Once removed, pull out any leftover remnants of the old line.

The next step is to cut a new line, which is usually 10-15 feet long. However, some recommend a longer line of 25 feet. Then, insert one end of the new line into the anchor hole inside the spool. It is important to ensure that the line does not twist while winding it onto the spool. Hold the spool in your left hand and turn it towards you, allowing the line to wind onto the spool.

Once the line is securely wound, with each end secured in the slots provided, push the ends into the eyelets of the outer casing of the head. Now, push the spool into the casing and onto the spring. To finish, give a short tug on each of the lines to release them from the slots, and install the bump knob on the head.

The final step is to replace the spool cap. Place it back onto the trimmer and ensure it clicks firmly into place.

Reinstalling the bump knob

To reinstall the bump knob, first install the spring and then push each end of the line, while still secure in the slots, into the eyelets of the outer casing of the head. Push the spool into the casing and onto the spring. When in place, give a short tug on each of the lines to release it from the slots. Now, you can install the bump knob on the head.

If you are using a straight shaft trimmer, you will need to turn the bump knob to the right to reinstall it. You will need a very large pair of pliers to hold the large part of the head and prevent it from turning. Then, grab the bump knob with another pair of pliers and turn it off. If the bump knob turns but the bolt inside doesn't, you may need to cut the plastic of the bump knob with a hacksaw to get to the bolt.

If your Toro trimmer has a spark plug, ensure that it is switched off and allowed to cool completely before attempting any maintenance. You should also remove the spark plug boot from the spark plug.

If your trimmer has a flathead screw, you can try unscrewing it from underneath the bump head. If the screw won't budge, you may need to take your trimmer to a Toro service dealer for assistance.
