Topcon RL-H4C Rotating Laser Level

• 40 hours - A600 Lithium-Ion (Li-Ion Pack)
• 60 hours - Alkaline (four D-cells)

• The product casts a horizontal laser plane or a laser beam for the purpose of alignment.
• The laser beam can be detected by means of a laser detector.
• Remote control of product.
• Data communication with external appliances

• Blow dust off lenses and prisms.
• Never touch the glass with your fingers.
• Use only a clean, soft, lint-free cloth for cleaning. If necessary, moisten the cloth with water or pure alcohol. Do not use other liquids; these can attack the polymer components.

• Simple and reliable, one button laser where no mistakes are possible
• Single axis slopes up to 45 ° with manual slope adapter
• High application performance with Leica Rod Eye 140 – with the built-in 12 cm detection window, you can easily detect the beam over the entire distance

Dirt and water on the glass parts of laser or prism will influence beam quality and operating range considerably. Clean with cotton swabs. Remove dirt on the housing with a lint-free, warm, wet and smooth cloth. Do not use harsh cleansers or solvents. Allow the unit to air dry after cleaning it. Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car). The unit is very robust and can resist damage if dropped even from tripod height. Before continuing your work, always check the leveling accuracy. See Accuracy Check section.

The laser is water proof and can be used indoors and outdoors.
