The Makita XRU09 Cordless Grass Trimmer is a battery-powered gardening appliance designed specifically for cutting grass and light weeds. It is not intended for other purposes such as edging or hedge cutting, as this could cause injury. The tool features a loop handle for comfortable operation and is designed for use with genuine Makita battery cartridges and recommended accessories.
Function Description
The XRU09 operates on a D.C. 36V battery system and utilizes a nylon cutting head for trimming. It offers two no-load speed settings, allowing users to adjust the cutting power based on the task at hand. The tool is equipped with a main power button to turn it on and off, and a lock-off lever to prevent accidental pulling of the switch trigger.
A key feature is the reverse button, which allows the nylon cutting head to rotate in the opposite direction. This function is specifically designed for removing entangled weeds and debris from the cutting head. When activated, the power lamp blinks, and the head rotates in reverse for a short period before automatically stopping.
The tool incorporates a tool/battery protection system that automatically cuts off power to the motor under certain conditions to extend the life of both the tool and the battery. These conditions include:
- Overload protection: If the tool is overloaded by entangled weeds or debris, it will stop automatically, and the indicators will blink. The user must turn off the tool, clear the obstruction, and then restart.
- Overheat protection: If the tool or battery overheats, it will stop automatically, and the indicators will blink for approximately 60 seconds. The tool should be allowed to cool down before restarting.
- Overdischarge protection: When the battery capacity becomes low, the tool stops automatically, requiring the batteries to be removed and charged.
The battery cartridge itself includes indicator lamps and a CHECK button to display the remaining battery capacity, helping users monitor power levels.
Usage Features
Before operation, users must ensure the tool is fully assembled, including the guard and nylon cutting head, and that the battery cartridge is securely installed. The grip should be fitted onto the pipe and tightened with hex bolts, positioned beyond the hanger. The protector (cutting tool guard) is essential for safety and must always be in place. The nylon cutting head is installed by aligning it with the threaded spindle and tightening it counterclockwise using a hex wrench.
To start the tool, the lock-off lever must be released by grasping the rear handle, and then the switch trigger pulled. The speed can be adjusted by tapping the main power button, with different indicator lights signifying high or low speed. For debris removal, the reverse button can be tapped while the head is stopped, followed by pulling the trigger.
The nylon cutting head is a dual string trimmer head with a bump & feed mechanism. To feed out more nylon cord, the cutting head should be bumped against the ground while rotating. It's crucial to use only genuine Makita nylon cutting heads and cords of the specified diameter to prevent damage and ensure safety.
For safe operation, the tool should always be positioned on the user's right-hand side to maintain maximum control and reduce kickback risk. Users must maintain a firm grip with both hands and ensure proper footing and balance. The working area should be clear of children, other people, and animals within a 15-meter (50 ft) radius.
Maintenance Features
Regular inspection and maintenance are vital for the tool's safety and reliability. Before any inspection or maintenance, the tool must be switched off, and the battery cartridge removed to prevent accidental start-up and serious personal injury.
Key maintenance tasks include:
- Checking the nylon cutting head: Before each use, inspect the nylon cutting head and protective devices for damage, cracks, or loose fasteners. If the head impacts hard objects during operation, it should be immediately inspected and replaced if damaged.
- Replacing the nylon cord: The manual provides detailed instructions for replacing the nylon cord. This involves removing the cover, winding the new cord onto the spool in the specified direction, and then reassembling the head. Only nylon cord of the specified diameter should be used.
- Cleaning: Handles should be kept dry, clean, and free from oil and grease. Ventilation openings must be kept clear of debris.
- Storage: When not in use, the tool should be stored indoors in a dry location, out of reach of children. The hex wrench, used for installing the nylon cutting head, has a designated storage spot on the tool to prevent loss.
- Battery care: Batteries should be charged before complete discharge and never recharged when fully charged to prolong service life. Charging should occur at room temperature (10°C - 40°C). If not used for long periods, batteries should be charged every six months.
Any repairs or adjustments beyond routine maintenance should be performed by Makita Authorized or Factory Service Centers, using only genuine Makita replacement parts. The use of gasoline, benzine, thinner, alcohol, or similar substances for cleaning is prohibited as they can cause discoloration, deformation, or cracks.
