Frequently Asked Questions - HL 20-SG Cocraft

What type of batteries does the Cocraft HL 20-SG laser pointer use?

The laser pointer requires 2 x AAA batteries (not included in the package).

How do I turn on the laser pointer continuously?

Press and hold the button for momentary use. For continuous mode, twist the button lock (usually clockwise) until it clicks into place.

What is the maximum distance the laser can reach?

In low light conditions, the beam can be visible up to 500 meters. Range may decrease in bright light.

Is the laser pointer safe for use around pets or children?

This is a Class 2 laser with output < 1 mW. While generally safe for accidental exposure, it is not recommended to point at eyes or use around pets/children without supervision.

How do I clean the lens of the laser pointer?

Use a dry, soft cloth to gently wipe the lens. Do not use liquids or abrasive cleaners as they may damage the optics.

Can I replace the batteries myself?

Yes. Unscrew the tail cap (or battery compartment), insert 2 AAA batteries with correct polarity, then close the compartment.

Why is the laser beam dim or not working?

First, check that batteries are installed correctly and have sufficient charge. Replace them if needed. Ensure the lens is clean and the pointer is not damaged.

What is the warranty period for this product?

The Cocraft HL 20-SG comes with a 1-year limited warranty against manufacturing defects. Proof of purchase is required.

Can I use rechargeable AAA batteries?

Yes, but note that rechargeable batteries typically have lower voltage (1.2 V) than alkaline (1.5 V), which may reduce brightness and operating time.

How should I store the laser pointer when not in use?

Remove the batteries to prevent leakage. Store in a cool, dry place away from direct sunlight and extreme temperatures.

Saftey

Laser classification

This meter produces a visible laser beam from the front of the instrument: it is a Class 2 laser in accordance with: IEC60825-1: 2014 Safety of laser products.

Warning symbol with a warning triangle and a cross-shaped object, no text or labels present

Laser class 2 products

Do not stare into the laser beam or direct it towards other people or animals. Risk of serious damage to eyes.

Warning! Do not look directly into the beam with optical aids such as binoculars or telescopes. Risk of serious damage to eyes.

Product safety symbols

Read the entire instruction manual.

Laser class 2

Make sure not to remove or damage the safety symbols and warnings found on the distance meter.

• Never try to open the housing, repair or modify the distance meter in any way.
• Only use accessories that are recommended by the manufacturer or retailer.
• Never use the distance meter where flammable or explosive substances are used or stored.
• Do not use the distance meter on or near highly reflective surfaces since the laser beam can be reflected back into your own or someone else's eyes.
• Keep the laser distance meter out of children's reach.

Operating instructions

Batteries

1. Remove the battery cover and insert 2 × AA/LR6 batteries (sold separately). Refer to the markings in the battery compartment to ensure correct polarity.
2. Refit the battery cover.

Switching the laser level on

Note:

• Never leave the product switched on unattended. Always switch it off after use. There is always a risk that someone could be blinded by the laser beam.
• Never point the laser towards people or animals and never look into the laser yourself even if you are not standing close to the laser level.

• Protect the laser level from wetness and persistent sunlight.

• Do not expose the laser level to extreme temperatures or rapid changes in temperature. Do not leave the laser level in your car for a long period. Extreme temperatures or rapid changes in temperature can affect the precision of the laser level.

• Avoid subjecting the laser level to heavy impacts or shocks. Damage to the laser level could affect its accuracy. The accuracy of the laser level should be tested against known references following any heavy impact or shock.
• Switch the laser level off before transporting it. When the laser level is switched off the levelling system locks to prevent it becoming damaged.

Automatic Self-Levelling

1. Position the laser level in a suitable place (free-standing or on a tripod/stand).
2. Set the [ON/OFF] switch (4) to the ON position. The laser beam will appear on the surface that the laser window is pointed towards and the auto-level indicator (2) will be green. Note: If the laser level is inclined more than 4^ form horizontal the auto-level indicator will shine red, the laser beam will flash and the self-levelling function will deactivate. Right the level by hand to within 4^ of horizontal and the automatic self-levelling function will reactivate.
3. Press [⏻] the required number of times to select the desired laser projection mode: horizontal, vertical or cross.
4. Slide the [ON/OFF] switch] to OFF to turn the laser level off.

Note:

• Always switch the laser level off after you have finished working or before moving it to a different location. When the laser level is switched off, a built-in lock mechanism is engaged to protect the levelling mechanism.
• In the event of vibrations and changes of position during use the laser level will automatically self-level. Each time the laser level has been levelled, the accuracy of the horizontal and vertical lines should be checked against a known reference in order to avoid errors.

Locked line mode

The projected laser line can be locked (self-levelling switched off) and the laser level tilted manually to any desired angle.

1. Slide the [ON/OFF] switch to OFF.
2. Press [⏻] to switch the laser level on. The auto-level indicator will now shine red.
3. Press [⏻] the required number of times to select the desired laser projection mode: horizontal, vertical, cross or no line at all.

Care and maintenance

• Always switch the laser level off before cleaning it, moving it, and after you have finished working.
- Clean the exterior of the laser level by wiping it with a damp cloth. Use only mild cleaning agents, never solvents or corrosive chemicals.
• Always treat the laser level with the care deserving of the precision optical instrument that it is.
- Do not subject the laser level to impacts, vibrations, extremely high or low temperatures.
- Remove the batteries and store the laser level in a dry, dust-free environment, out children's reach whenever it is not to be used for an extended period.

Troubleshooting guide

The laser level will not switch on.	Check the capacity of the batteries and make sure that they are inserted correctly. Follow the markings on the bottom of the battery compartment.
The laser line flashes during self-levelling.	The incline angle has been exceeded (4°).Right the laser level.
The laser level shuts down after a few seconds use.	The batteries are flat. Change the batteries.
The laser line is not clear. •	Check the batteries and replace if necessary.• Check the laser window; clean it with a soft cloth if necessary.• Ambient light level too high.
