We strive to make the Theragun as safe as possible. This is an advanced mechanical tool with electric components. If the Theragun and its accessories are not used or maintained properly, there is a risk of fire, electric shock, or injury. When using the Theragun, these basic precautions should always be followed including:

USE ONLY AS INSTRUCTED. Use the G3PRO as described in this Instruction Manual. Use only Theragun recommended accessories and replacement parts. Do not carry out any maintenance other than as advised by Theragun.

NOT FOR CHILDREN. The G3PRO and charger are not intended for use by young children or persons with reduced physical, sensory or reasoning capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction by a responsible person. Do not allow the G3PRO to be used as a toy. Close attention is necessary when used by or near children. Children should be supervised to ensure that they do not play with the G3PRO or charger.


REDUCING RISK OF INJURY. Charge the G3PRO only in Theragun G3PRO charger. Other chargers may cause personal injury or damage. Do not connect the G3PRO to a power supply plug or car cigarette lighter. The internal battery will be permanently disabled or damaged.

USE THE G3PRO ONLY WITH THERAGUN G3PRO BATTERIES. Use of other batteries may result in a risk of fire, electric shock, or personal injury.

CHARGING LOCATIONS. The Theragun should be charged indoors in a well ventilated, dry location. Do not charge the Theragun outdoors, in a bathroom or within 10 feet (3.1 meters) of a bathtub, or pool. Do not use the Theragun or charger on wet surfaces and do not expose the charger to moisture, rain, or snow. Do not use the Theragun or charger in the presence of explosive atmospheres (gaseous fumes, dust, or flammable materials). Sparks may be generated, possibly causing a fire.

UNPLUGGING THE CHARGER. Pull the plug, not the cord, to reduce the risk of damage to the electrical plug and cord. Never carry charger by its cord. Keep the cord from heat, oil, and sharp edges. Do not use or charge with a damaged cord. Do not stretch the charger cord or place the cord under strain. Keep cord away from heated surfaces. Do not handle the charger, including the charger terminals or Theragun with wet hands.

CHARGER CARE. Unplug the charger when not in use. Unplug the charger from the outlet when not in use for extended periods. Make sure the charger cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. Have a damaged charger replaced immediately.

DO NOT OVERCHARGE. Do not leave the battery in the charger for more than an hour after the battery has been fully charged. The battery includes a protection system to avoid the risk of overcharging. However, overcharging may reduce its life over time.

DO NOT BLOCK MOTOR VENTS. Do not put any obstructions into vents. Do not use if any vent is blocked. Keep free of dust, lint, hair, and anything that may reduce airflow. Keep hair, loose clothing, and fingers from vents and moving parts.

DO NOT BURN OR INCINERATE THE THERAGUN OR ITS BATTERY. The battery may explode, causing personal injury or damage. Toxic fumes and materials are created when the battery is burned.

DO NOT CRUSH, DROP, OR DAMAGE THE G3PRO CHARGER. Do not use a charger that has received a sharp blow, been dropped, run over, or damaged in any way.

BATTERY CHEMICALS CAUSE SERIOUS BURNS. Never allow the internal battery to come into contact with the skin, eyes, or mouth. If a damaged battery leaks chemicals, use rubber or neoprene gloves to dispose of it. If skin is exposed to battery fluids, wash with soap and water and rinse with vinegar. If eyes are exposed to battery chemicals, immediately flush with water for 20 minutes and seek medical attention. Remove and dispose of contaminated clothing.

DO NOT SHORT CIRCUIT. A battery will short circuit if a metal object makes a connection between the positive and negative contacts on the battery or the 12V connector. A short-circuited battery may cause fire and personal injury.

DO NOT OPERATE UNDER BLANKET AND PILLOW. Excessive heating can occur and cause fire, electric shock, or injury.

STORING THE G3PRO AND CHARGER. Store in a cool, dry place. Only charge the G3PRO when the ambient temperature is between 0°C/32°F and 40°C/104°F. Do not store the G3PRO where temperatures may exceed 40°C/104°F such as in direct sunlight, in a vehicle, or metal building during the summer.

DISPOSING OF BATTERIES. The Theragun Lithium-ion batteries for the G3PRO are more environmentally friendly than some other types of batteries. Always dispose of the G3PRO according to federal, state, and local regulations. Contact a recycling agency in your area for recycling locations. Even discharged batteries contain some energy. Before disposing of, use electrical tape to cover the G3PRO’s 12V connector to prevent the battery from shorting, which could cause a fire or explosion.

DO NOT DISASSEMBLE. Disassembly or incorrect reassembly may result in the risk of electric shock, fire, or exposure to battery chemicals. The warranty will be void if the G3PRO, or charger are disassembled or if any parts have been removed.

SERVICE. If the G3PRO battery or charger is not working properly, has received a sharp blow, has been dropped, damaged, left outdoors, or dropped into water, do not use and contact Theragun by emailing info@theragun.com for repair or service. Do not attempt to repair or disassemble the Theragun G3PRO which may result in an electric shock or fire.

DO NOT USE WHILE BATHING OR IN TUB OR SINK. Do not place the Theragun or charger where it can fall into a tub or sink. Do not place in or drop into water or other liquid. Do not reach for an appliance that has fallen into water. Unplug immediately.

THERMAL LIMITER. The Theragun has an automatic reset thermal limiter that shuts off the Theragun to prevent overheating and fire.
