The reverse switch aids in clearing tangled grass clippings, and the rear-end mounted motor ensures optimal tool balance.

2. Safety Instructions

Always prioritize safety when operating power tools. Read and understand all safety warnings and instructions before using the brush cutter. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.

2.1 Personal Protective Equipment (PPE)

• Eye Protection: Always wear safety glasses or goggles that comply with applicable standards.
• Hearing Protection: Wear ear defenders or earplugs to protect against noise-induced hearing loss.
• Head Protection: A hard hat may be necessary in areas with falling debris.

4. Setup

Proper assembly and preparation are crucial for safe and effective operation.

4.1 Assembly

1. Handle Assembly: Attach the bike handle to the main shaft using the provided fasteners and hex wrenches. Ensure it is securely tightened and positioned for comfortable operation.
2. Guard Installation: Secure the cutting guard to the shaft above the cutting head. This guard is essential for protecting the operator from debris.
3. Cutting Head Attachment: Install the nylon cutting head onto the spindle. Refer to the specific instructions for the cutting head type for proper attachment and tightening using the box wrench.

4.2 Battery Charging and Installation

1. Charge Batteries: Connect the charger to a power outlet. Insert both 40V Max XGT Li-ion batteries into the charger. Allow them to fully charge before first use. The charger will indicate when charging is complete.
2. Install Batteries: Once charged, slide both batteries into the designated battery slots on the brush cutter until they click securely into place. Ensure both batteries are fully seated for the tool to operate.

4.3 Shoulder Belt Adjustment

Attach the shoulder belt to the brush cutter's designated attachment point. Adjust the length of the belt so that the cutting head is comfortably positioned just above the ground when you are standing upright. This helps distribute the tool's weight and reduces operator fatigue.

5. Operating Instructions

Follow these steps for safe and effective operation of your Makita UR012G brush cutter.

5.1 Pre-Operation Check

• Ensure all fasteners are tight and the cutting head is securely attached.
• Check the battery charge level.
• Clear the work area of any obstacles, rocks, or debris that could be thrown by the cutting head.
• Wear all required Personal Protective Equipment (PPE).

5.2 Starting and Stopping

1. To Start: Press the main power button. The tool will enter standby mode. Then, depress the trigger switch to start the cutting head. The soft start feature will ensure a gradual ramp-up.
2. To Stop: Release the trigger switch. The electric brake will quickly stop the cutting head. Press the main power button again to turn off the tool completely.

5.3 Speed Settings and ADT Mode

Use the electronic 3-speed settings (Hi/Med/Lo) to match the cutting speed to the density of the vegetation.

• Low (Lo): For light trimming and extended battery life.
• Medium (Med): For general grass cutting.
• High (Hi): For dense brush and heavy-duty cutting.
• ADT Mode: When activated, the tool automatically adjusts the cutting speed and torque based on the load, optimizing performance and battery life.

5.4 Using the Reverse Switch

If the cutting head becomes tangled with grass or weeds, release the trigger, then activate the reverse switch. This will cause the cutting head to spin in reverse, helping to clear the obstruction. Once cleared, return the switch to the forward position before resuming cutting.

5.5 Cutting Techniques

• Maintain a firm grip on the handles.
• Swing the brush cutter in a smooth, sweeping motion.
• Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the cutting head and cause kickback.
• Work away from your body and ensure bystanders are at a safe distance.

6.2 Cutting Head/Line Replacement

Periodically inspect the nylon cutting line for wear. Replace the line or the entire cutting head as needed. Refer to the cutting head's specific instructions for replacement procedures. Always ensure the tool is off and batteries are removed before performing any maintenance.

6.3 Battery Care and Storage

• Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
• Do not store batteries in a discharged state for extended periods. Charge them periodically if not in use.
