- Maintain Appliance With Care – Replace string head if cracked, chipped, or damaged in any way. Be sure the string head is properly installed and securely fastened.
Keep cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Inspect appliance cord periodically, and if damaged, have it repaired by an authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease. Failure to do so can cause serious injury. - Check damaged parts before using the appliance, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, damaged mountings, and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless indicated elsewhere in this manual.
- Remove or disconnect battery before servicing, cleaning or removing material from the gardening appliance.
- Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care. Use appliances only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. Use only Greenworks 29652 battery or other BAF series.
- Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. Use only Greenworks 29692 charger or other CAF series.
- When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
- Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
- Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause an explosion.
- Do not dispose of the batteries in a fire. The cells may explode. Check with local codes for possible special disposal instructions.
- Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
- Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.
- Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside of the specified range may damage the battery and increase the risk of fire.
- Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
- Keep guards in place and in working order.
- Keep hands and feet away from cutting area.
- Disconnect the battery pack from the appliance before making any adjustments, changing accessories, or storing appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.

FAQS
What is the difference between Greenworks G-MAX 40V and Greenworks G-MAX 40V GT?
The only difference is that the GT version has a grass blade.
How long does it take to charge the battery?
It takes about 60 minutes to fully charge the battery. However, you can use it while it’s charging. You’ll get about 45 minutes of run time on a fully charged battery.
Are extra batteries available for purchase?
Yes, extra batteries are available for purchase. Here is the link to the compatible G-Max 40v batteries https://www.amazon.com/GreenWorks-29462-G-MAX-Li-Ion-Battery/dp/B00AW72XFQ/ref=sr_1_3?ie=UTF8&qid=1507209379&sr=8-3&keywords=G-Max+40v+batteries. If you have trouble with this process, please feel free to contact us at 1-888-909-6757 for assistance.
How long does the 2AH battery last?
The 2.0Ah 40v battery can last around 20-25 minutes depending on the type of weeds you’re using it on.
Does this come with the string, oil and other essentials needed?
It came with the string and battery and charger. Ours arrived,we charged the battery,plugged it in thetrimmer and trimmed our whole yard, front and back with power to spare. We don’t mess with cords,gas,or oil anymore and trimming the yard is now a pleasure instead of a curse. The only thing is,it doesn’t have auto feed for the string. The button for it is on the side of the spool instead of the bottom and you have to manually press it to advance the string. It’s a small price to pay for not having to mess around with cords,gas,oil,hard starting, etc
Has anyone been able to fix the auto feed feature? Mine has never worked since day 1… going on over two years with this thing.
We’re sorry to hear you are having problems with the automatic feed with your unit. So we can assist in addressing this issue, please contact our helpline at 1-888-909-6757.
Is 40 volt more powerfull than 20 v
The simple answer is yes. Mathematically power (the rate of work being done) is volts times current. So the higher the voltage the more work that can be done for the amount of current stored in the battery.
What is the overall length of this unit, as i am tall and dont like bending over?
This string trimmer would be approximately 59″ in length.
Is the pole adjustable on this model?
This string trimmer does not have an adjustable pole.

Does the charger support 220/240 volt
No it does not. but you can buy any step-down voltage converter 220VAC to 110VAC with the same or more wattage to resolve the issue.
does one battery fit all green works products? looking at 16″ chain saw, and weed trimmer, need to know if they use same battery?
If it is a 40v Gmax battery you must use in a gmax unit. If you buy a gmax weed trimmer that uses the gmax battery, the chain saw must also be a gmax saw. You can’t use a regular battery in a gmax unit. I bought the gmax lawn mower, weed trimmer and hand held blower. They all are gmax so I have extra batteries and a charger enabling me to have all the battery power i need. I am also very happy with all the gmax units I purchased. It should tell you the batteries needed in the description of unit you are looking to purchase. make sure they all use the same battery and you will have no problem.
what are the spool cap dimensions??
Don’t waste your money, you won’t be happy with it. It is awkward, heavy, no balance to get the head level, line does not feed half the time. JUNK not to mention the battery has a full charge but the motor cuts out every 10 seconds. Greenworks support is non existent. buyer beware
can a green works 40v lithium max 2.5ah battery model baf722 be used with the 21332 string trimmer?
This trimmer sucks. Waste of money
Will this one work with the greenworks 40v 150 mph variable speed cordless leaf blower, 2.0ah, 24252 2ah battery
Yes, that battery 24252 is a GMax 40V 2Ah battery and will fit this 13-inch 40V cordless string trimmer.
