Attaching the top portion of the handlebar

To attach the top portion of the handlebar of your Greenworks 21 electric mower, you will need to follow a few simple steps.

Firstly, locate the top portion of the handlebar and identify where it attaches to the mower. There should be two bolts that need to be tightened to secure the handlebar in place. Using the appropriate tool, tighten these bolts securely, but be careful not to over-tighten them.

Once the bolts are tightened, check that the handlebar is securely attached and doesn't wobble or move when you apply a little pressure. If it feels secure, you can move on to the next step. If not, double-check that the bolts are tightened correctly and that there are no issues with the threading or alignment.

Now, you can adjust the handlebar to your preferred height and angle. This adjustment mechanism will vary depending on your mower model, so refer to your user manual for specific instructions. Ensure the handlebar is locked into place at your desired setting.

Finally, give the handlebar a test run by gripping it and simulating your mowing motion. Ensure it feels comfortable, secure, and doesn't obstruct your movement in any way. If you're satisfied with the positioning and stability, your Greenworks 21 electric mower's handlebar is now fully assembled and ready for use.

Tightening two bolts on the handlebar

The Greenworks 13 Amp 21-Inch Electric Lawn Mower is easy to assemble. The assembly consists of attaching the top portion of the handlebar and tightening two bolts.

To tighten the two bolts on the handlebar, you can follow these steps:

Firstly, ensure you have the correct tools for the job. You will need a set of assorted socket and Allen wrenches and drivers with appropriate bits. A corded electric drill can also be useful.

Next, you will want to tighten the bolts to the correct torque. This can be tricky to judge by hand, and it is easy to under or overtighten, so it is recommended to use a torque wrench if you have access to one. The goal of torque is to stretch the bolt, putting it under tension and holding it from coming loose. You will feel this "stretch" as you slowly tighten the bolt, as the torque required will suddenly increase.

If you do not have a torque wrench, there are other methods you can use. One suggestion is to tighten the bolt until something breaks, and then loosen it by a quarter turn. Another method is to tighten the bolt in a cross pattern to equalize pressure on the bars until it feels secure.

Finally, if your mower has two bolts, you should alternate the bolt you are tightening. Tightening one bolt will reduce the tension on the other, so by alternating, you will keep the torque between them even.

Tightening two bolts on the lower portion

To tighten the two bolts on the lower portion of your Greenworks 21 electric mower, you will need to locate the bolts on the lower handlebar. Using the appropriate tool, tighten the bolts until the handlebar feels secure. Be careful not to over-tighten the bolts, as this may strip the threads or damage the handlebar.

It is important to ensure that the bolts are tightened correctly as this will affect the stability and performance of the mower. Loose bolts can cause the handlebar to wobble, making it difficult to control the mower and achieve a straight cutting line.

Additionally, loose bolts can be a safety hazard as they can cause the handlebar to become unstable or detach during use. It is recommended to check the tightness of the bolts periodically and tighten them as necessary to ensure the mower is always safe and ready for use.

By following these steps and maintaining the proper bolt tightness, you can ensure the optimal performance and safety of your Greenworks 21 electric mower.

Charging the battery

To charge the battery, place it securely into the designated charger. While your battery is charging, you can prepare the other parts of your electric mower. For example, you can bag your lawn and ensure your side discharge flap is flush with the mower. You can also take out the bagging plug before you clip in your bagger. Alternatively, if you want to mulch your lawn, check that the side discharge flap is flush and the mulching plug is in place.

The Greenworks 80V 21" electric mower features dual battery ports with Auto Switch technology. This means that when one battery is depleted, the mower's power supply is automatically switched to the second battery.

The Greenworks PowerHUB can be integrated with the utility grid, solar panels, and even a generator. The brand offers versatile voltage platforms ranging from 24V to 80V.

Safety precautions

Safety should always be the top priority when operating machinery such as a lawn mower. Here are some crucial safety precautions to follow when assembling and operating your 21" Greenworks electric mower:

Precautions before use

Before you start using your mower, carefully read all the safety rules, instructions, and warnings in the manual and on the mower itself. Keep the manual in a safe place for future reference. Ensure that you understand how to operate the controls, including how to stop the mower and disengage the power in an emergency.

Do not allow children under the age of 14 to operate the mower. Children aged 14 and above must understand the operating instructions and safety rules and must be trained and supervised by a parent.

Inspect the area where you plan to use the mower. Remove any objects that could be tripped over or thrown by the blade, such as stones, sticks, wires, and toys. Thrown objects can cause serious injury.

Precautions during use

To avoid contact with the blade or injury from thrown objects, always stay in the operator's zone behind the handles. Keep children and bystanders at least 50 feet away.

Do not use the mower in wet conditions or during rain as unstable footing could cause you to slip. Keep the mower indoors in a dry area when not in use, and store it locked up or out of the reach of children.

Electrical safety

The Greenworks 21" electric mower is equipped with double insulation, which eliminates the need for a three-wire grounded power cord. This provides two complete sets of insulation to protect the user from electric current.

To further reduce the risk of electric shock, use a polarized extension cord that is approved for outdoor use, such as Type SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SUTOW-A. Ensure the cord is in good condition, heavy enough to carry the current, and polarized (one blade of the plug is wider than the other).

As an added safety measure, provide Ground Fault Circuit Interrupter (GFCI) protection on the circuit(s) or outlet(s) powering the mower.

Other precautions

Keep safety devices such as guards, shields, and switches in place and ensure they are functioning correctly.

Always look down and behind before and while moving backward to avoid accidental collisions.

When mowing on slopes, go across them rather than up and down to reduce the risk of injury.

Regularly inspect the grass catcher components, discharge cover, and trail shield. Replace any parts that show signs of wear or are cracked or broken, using only original equipment manufacturer's (OEM) parts listed in the manual.

Frequently asked questions

Assembly is straightforward and consists of attaching the top portion of the handlebar and tightening two bolts.

Greenworks mowers require much less maintenance than traditional gas mowers. However, they still require routine seasonal maintenance. After each use, it is advised to empty the bag (if bagging has been used), then check and clean off debris on the side discharge, rear slot, and underside of the deck. You should also wipe the unit down and check for loose nuts and bolts.

Before operation, thoroughly inspect the area and remove all stones, sticks, wire, toys, and other objects that could be tripped over or thrown by the blade. Then, ensure your batteries are charged and placed securely into the designated charger. If you want to bag your lawn, ensure your side discharge flap is flush with the mower and take out the bagging plug before clipping in your bagger. If you want to mulch your lawn, check that the side discharge flap is flush and the mulching plug is in place.

To power down your mower, simply push the on/off button. Find a spot in your garage or shed for storage. You can also fold it in half and hang it.
