It may result in loss of your eyesight. Do not short the battery cartridge. Do not touch the terminals with any conductive material. Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc. Do not expose battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a breakdown. Do not store and use the tool and battery cartridge in locations where the temperature may reach or exceed 50 °C (122 °F). Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire. Do not nail, cut, crush, throw, drop the battery cartridge, or hit against a hard object to the battery cartridge. Such conduct may result in a  fire, excessive heat, or explosion. Do not use a damaged battery. The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements. For commercial transports e.g. by third parties,forwarding agents, special requirement on packaging and labeling must be observed. For preparation of the item being shipped, consulting an expert for hazardous material is required. Please also observe possibly more detailed national regulations. Tape or mask off open contacts and pack up the battery in such a manner that it cannot move around in the packaging.When disposing the battery cartridge, remove it from the tool and dispose of it in a safe place. Follow your local regulations relating to
disposal of battery. Use the batteries only with the products specified by Makita. Installing the batteries to non-compliant products may result in a fire, excessive heat, explosion, or leak of electrolyte. If the tool is not used for a long period of time, the battery must be removed from the tool. During and after use, the battery cartridge may take on heat which can cause burns or low temperature burns. Pay attention to the handling of hot battery cartridges. Do not touch the terminal of the tool immediately after use as it may get hot enough to cause burns. Do not allow chips, dust, or soil stuck into the terminals, holes, and grooves of the battery cartridge. It may result in poor performance or breakdown of the tool or battery cartridge. Unless the tool supports the use near high-voltage electrical power lines, do not use the battery cartridge near high voltage electrical power lines.

Adjust the shoulder harness to a comfortable working position.

The shoulder harness features a means of quick release. Simply squeeze the sides of the buckle to release the tool from the shoulder harness.

Correct handling of the tool

Always position the tool on your right hand side. Correct positioning of the tool allows for maximum control and will reduce the risk of serious
personal injury.

WARNING
Be extremely careful to maintain control of the tool at all times. Do not allow the tool to be deflected toward you or anyone in the work vicinity. Failure to keep control of the tool could result in serious injury to the bystander and the operator. To avoid accident, leave more than 15m (50 ft) distance between operators when two or more operators work in one area. Also, arrange a person to observe the distance between operators. If someone or an animal enters the working area, immediately stop the operation.

CAUTION
If the cutting tool accidentally impacts a rock or hard object during operation, stop the tool and inspect for any damage. If the cutting tool is damaged, replace it immediately. Use of a damaged cutting tool may result in serious personal injury. Correct positioning and handling allow optimum control and reduce the risk of injury.

When using a nylon cutting head (bump & feed type.The nylon cutting head is a dual string trimmer head provided with a bump & feed mechanism. To feed out the nylon cord, tap the cutting head against the ground while rotating.

Cleaning the tool

Clean the tool by wiping off dust, dirt, or cut off grass with a dry cloth or one dipped in soapy water and wrung out. To avoid overheating of the tool, be sure to remove
the cut off grass or debris adhered to the vent of the tool.

Replacing the nylon cord

Use only the nylon cord with diameter specified in this instruction manual. Never use heavier line, metal wire, rope or the like. Failure to do so may cause damage to the tool
and result in serious personal injury. Always remove the nylon cutting head from the tool when replacing the nylon cord. Make sure that the cover of the nylon cutting head is secured to the housing. Failure to properly secure the cover may cause the nylon cutting head to fly apart resulting in serious personal injury. Replace the nylon cord if it is not fed any more. The method of replacing the nylon cord varies depending on the type of the nylon cutting head.
