Bosch GRL 300 HV Professional Rotation Laser Set with Receiver

PRIMARY USES

1. Large-Scale Levelling and Alignment for Construction

Primary Use: A professional rotating laser level with receiver (300m diameter working range) used for establishing horizontal and vertical reference planes over large distances. Essential for foundation work, formwork alignment, ceiling installation, and exterior grading.

How it helps: For surveyors, civil engineers, and construction managers, the rotating laser eliminates the need for traditional optical levels and manual staff reading. The self-levelling pendulum system automatically levels within ±5° (8%) in both horizontal and vertical modes . The GRL 300 HV provides point, line, and rotation modes for optimum visibility across different job site conditions . With the LR 1 Professional receiver, the working range extends to 300 metres in diameter, making it suitable for large outdoor projects .

2. Exterior and Long-Distance Levelling

Primary Use: Establishes elevation reference points over long distances for site grading, road construction, and landscaping.

How it helps: The receiver detects the rotating laser beam even in bright sunlight at distances up to 300 metres . The visual and audible alignment signals on the LR 1 receiver make it easy for a single operator to take accurate measurements across large sites . The IP54 dust and splash protection ensures reliable operation in typical outdoor construction conditions .

3. Interior Ceiling and Floor Installation

Primary Use: Projects a 360° horizontal plane for suspended ceiling installation, flooring work, and interior fit-out.

How it helps: The rotating laser creates a continuous reference plane around an entire room, allowing multiple workers to align ceiling grids, partition walls, and fixtures simultaneously. The rotation speed can be adjusted to 150, 300, or 600 rpm for optimum visibility in different lighting conditions .

SECONDARY USES

1. Formwork and Concrete Work: Establishes consistent elevation levels for concrete slab pours and formwork installation.

2. Plumbing and Vertical Alignment: The vertical self-levelling mode provides a vertical reference plane for lift shaft installation, column alignment, and building elevation work.

3. Equipment Installation: Provides precise reference lines for installing heavy equipment, conveyor systems, and industrial machinery.

4. Site Surveying: The LR 1 receiver can be mounted on a grade rod for quick elevation checking across large sites .

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Laser Safety: This device is a Class 3R laser product (<5mW). Do not stare directly into the laser beam. Do not point the laser at mirrors, reflective surfaces, or into the eyes of people or animals.

Environmental Safety: Do not use the tool in rain or wet conditions beyond IP54 rating. Avoid extreme temperatures outside -10°C to +50°C operating range.

Battery Safety: Use only recommended battery types (LR20 D batteries or NiMH rechargeable). Do not mix old and new batteries. Remove batteries if device will not be used for long periods.

Operational Safety: Ensure the tool is placed on a stable surface or securely mounted on a tripod. Self-levelling range is ±5°; if exceeding this range, tool will not self-level and will indicate error.

Maintenance: Clean laser windows regularly with a soft cloth. Do not use aggressive cleaning agents. Have repairs performed only by authorised service centres.

Training requirement: Operators should be familiar with rotating laser operation, receiver handling, and safety precautions. Supervisors should ensure all safety protocols are followed, particularly regarding laser safety.

2. FIRST AID MEASURES

Eye Exposure (laser beam): If laser beam enters the eye, close eyes and turn head away immediately. If irritation persists, seek medical attention.

Skin Contact: Generally not harmful. If irritation develops, wash with soap and water.

Battery Leakage: Avoid skin contact with battery acid. Wash affected area with soap and water. Seek medical attention if irritation occurs. If acid enters eyes, rinse with plenty of clean water for at least 15 minutes and seek immediate medical attention.

Inhalation: Not applicable for normal use.

Ingestion: Not applicable for normal use.

3. FIRE FIGHTING MEASURES

Flammability: Device housing is not highly flammable but may burn if exposed to fire. Batteries may leak or rupture if exposed to high temperatures.

Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide (CO₂) for fires involving tools.

Fire Response: In event of fire, evacuate the area and call emergency services. Use appropriate extinguishers. Do not inhale fumes from burning batteries or plastics.
