Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury. Always switch off the tool before installing or removing the battery cartridge.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.

To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely. Install it fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

NOTE: Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

Overloaded: The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded. Then pull the trigger switch again to restart.

If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the trigger switch again.

Low battery voltage: The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Running the tool allows the indication lamp to show the battery cartridge capacity status. When the tool is also overloaded and has stopped during operation, the lamp lights up in red. Refer to the following table for the status and action to be taken for the indication lamp.

Note 1: The time at which the indication lamp lights up varies by the temperature around the work area and the battery cartridge conditions.

WARNING:

Always be sure that the tool is switched off and battery cartridge is removed before carrying out any work on the tool. Failure to switch off and remove the battery cartridge may result in serious personal injury from accidental start-up.

Never start the tool unless it is completely assembled. Operation of the tool in a partially assembled state may result in serious personal injury from accidental start-up.

Installing the front grip

Put the front grip on the front grip holder and secure it with a hex bolt and the clamping nut provided with the string trimmer as shown in the figure. At this time, the hex bolt needs to be installed from the side in which the hex bolt lock port is located and the clamping nut needs to be installed from the opposite side.

NOTE: The front grip has an edge-to-edge cut slit in its mounting area. Using this slit allows you to easily install the front grip on the front grip holder.

The front grip angle is adjustable. To adjust the front grip angle, loosen the clamping nut, set the front grip at a proper angle according to your work and then tighten the nut clockwise firmly.

Installing the guard

CAUTION: While installing the guard, be careful not to contact the nylon cord cutter provided on the guard. Contact with the cutter could result in personal injury.

Mount the guard by fitting it on to the motor housing so that the Nylon cord is not pinched between the guard and the motor housing, and then secure it with two screws. Before starting the trimmer, take away the cutter cover from the cord cutter.

WARNING: Before adjusting the shaft length, release the switch trigger and remove the battery cartridge from the string trimmer. Failure to release the trigger and removing the battery cartridge may cause a personal injury.

To adjust the length of the shaft, turn the grip counterclockwise until the shaft is unlocked and pull out or push in to the desired length.

Installing or removing the Nylon cutting head

WARNING: Before installing or removing the Nylon cutting head (both spool cover and spool), make sure that the tool is switched off and the battery cartridge is removed from the tool.

CAUTION: While installing or removing the Nylon cutting head, be careful not to contact the nylon cord cutter provided on the guard.

To remove the Nylon cutting head (spool and spool cover), press in the latches forcefully on both sides of the spool cover and raise it.

To install a cord-newly-wound Nylon cutting head, align the Nylon cord eyehole with the notch of the Nylon cutting head installation port on the trimmer and then press it in until a click is heard.

Winding a new Nylon cord on the spool

1. Remove the spool from the spool cover and take off the remaining used Nylon cord from the spool.

2. Insert a Nylon cord to the retainer shown in the figure.

3. Wind it tightly flat around the spool in the direction of the arrow on the spool so that the wound Nylon cord surface appears uniform over the winding area.

4. Temporarily fix a Nylon cord at the notch shown in the figure.

5. Bring the Nylon cord through the Nylon cord eyehole in the spool cover.

6. After installing the Nylon cutting head, make sure that the Nylon cord comes out by pressing the spool and pulling the Nylon cord.

Attachment of shoulder strap: Hook the shoulder strap in a hole in the front grip.

Operation Cautions:

Do not cut high grass at a time. Cutting high grass at a time near the root may cause the trimmer motor spindle to be entangled by grass which leads to the motor under overload, resulting in damage to the trimmer.

Use the trimmer without getting the spool into contact with the ground surface. Using the spool contacting the ground surface may cause the motor under overload resulting in damage to the trimmer.

Do not force the trimmer in densely growing grass.

Do not use the trimmer as if you dig out the ground with it.

Cutting grass near a tree, concrete block, brick or garden stone:

Hold the trimmer tilting at a level so that it does not contact the ground surface and cut the grass using the Nylon cord tip like knocking the ground. Smooth feeding out is needed because the Nylon cord wears more quickly than usual.

NOTE: Getting the trimmer too close to an obstacle may cause the Nylon cord to be cut off halfway inside the spool cover. If this happens, reset the Nylon cord properly. It is recommended to keep the tool more than 5 cm away from obstacles.

Start the trimmer before getting close to the grass. Cut the grass using the Nylon cord tip by moving the trimmer from right to left and proceed slowly, keeping the trimmer tilted at an angle of about 30° in relation to the ground surface. When cutting high grass, cut in layers always beginning from the top with each cut length short.

Using the tool as an edger:

1. Hold the shaft of the trimmer with one hand and turn the grip counter clockwise to loosen the shaft.

2. Rotate the shaft with the motor housing 180° and tighten the grip clockwise until it locks.

NOTE: Before rotating the shaft, it needs to be fully shortened or extended. After changing to the edger position, make sure that the motor housing and shaft are locked.

To obtain a good result of finish cutting, move parallel to the edge you are going to perform an edging work.

Cutting grass in a tight place or on a slope:

To ease the work in a tight place, push the lock button and then bend down the cutting head so that the shaft is parallel to the ground surface. Adjusting the cutting head angle properly in this way helps you cut the grass on a slope.

WARNING: Always be sure that the tool is switched off and battery cartridge is removed before attempting to perform inspection or maintenance on the tool. Failure to switch off and remove the battery cartridge may result in serious personal injury from accidental start-up.

NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
