Safety Notes

Surface laser
All instructions must be read and observed in order to work safely with the measuring tool. Never make warning signs on the measuring tool unrecognizable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN GIVING IT TO A THIRD PARTY.
Caution – The use of other operating or adjusting equipment or the application of other processing methods than those mentioned here can lead to dangerous radiation exposure.
The measuring tool is provided with two warning labels (each marked with the number 2 in the representation of the measuring tool on the graphics page).

BOSCH RC 2 GSL 2 Professional Floor Laser - FIGURE 4

If the text of the warning labels is not in your national language, stick the provided warning labels in your national language over it before operating for the first time.

Do not direct the laser beam at persons or animals and do not look into the laser beam yourself. This measuring tool generates laser radiation from class 3R according to IEC 60825-1. Looking directly into the laser beam
– even from a greater distance can cause damage to the eyes.
If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head away from the beam.
Do not use the laser viewing glasses as safety goggles.
The laser viewing glasses are used for improved visualization of the laser beam, but they do not protect against laser radiation.
Do not use the laser viewing glasses as sunglasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce color perception.
Do not make any modifications to the laser equipment.
Has the measuring tool been repaired only through qualified specialists using original spare parts? This ensures that the safety of the measuring tool is maintained.
Avoid reflection of the laser beam on smooth surfaces such as windows or mirrors. A reflected laser beam can also cause damage to the eye.
The measuring tool should be operated only by persons that are familiar with the handling of laser devices. According to EN 60825-1, this includes, among other things, the knowledge about the biological effects of the laser on the eyes and the skin as well as the correct usage of laser protection devices in order to avoid dangers.
Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases, or dust. Sparks can be created in the measuring tool which may ignite the dust or fumes.
Always set up the measuring tool in such a manner that the laser beams run far above or below eye level. This ensures that damage to the eyes will not occur.
Mark the area in which the measuring tool is being used with suitable laser warning labels. This prevents persons not involved from accessing the dangerous area.
Do not store the measuring tool at locations to which unauthorized persons have access. Persons not familiar with the operation of the measuring tool can cause harm to themselves and to others.
When using a class 3R measuring tool, observe possible national regulations. Non-observance of these regulations can lead to injury.
Make sure that the area of laser radiation is monitored or shielded. The limitation of laser radiation to controlled areas prevents eye damage to persons not involved.
Before any work on the measuring tool itself (e.g. assembling, maintenance, etc.) as well as when transporting and storing, remove the battery pack or the batteries from the measuring tool. The danger of injury when accidentally actuating the On/Off switch.
Do not open the battery pack. The danger of short-circuiting.
Protect the battery pack against heat, e.g., against continuous intense sunlight, fire, water, and moisture. The danger of explosion.
When the battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery pack; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help.
Liquid ejected from the battery pack may cause irritations or burns.
In case of damage and improper use of the battery pack, vapors may be emitted. Provide fresh air and seek medical help in case of complaints. The vapors can irritate the respiratory system.
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use the battery pack only in conjunction with your Bosch measuring tool. This measure alone protects the battery pack against dangerous overload.
Use only original Bosch battery packs with the voltage listed on the nameplate of your measuring tool. When using other battery packs, e.g. imitations, reconditioned battery packs, or other brands, there is a danger of injury as well as property damage through exploding battery packs.
BOSCH RC 2 GSL 2 Professional Floor Laser - ICON 3Keep the measuring tool and the laser target plate 10 away from cardiac pacemakers. The magnets of the measuring tool and laser target plate generate a field that can impair the function of cardiac pacemakers.
Keep the measuring tool and the laser target plate 10 away from the magnetic data medium and magnetically sensitive equipment. The effect of the magnets of the measuring tool and laser target plate can lead to irreversible data loss.
Remote Control (GSL 2 Set)
Read and observe all instructions. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
Have the remote control repaired only through a qualified repair person and only use identical replacement parts. This will ensure that the functionality of the remote control is maintained.
Do not operate the remote control in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Sparks can be created in the remote control which may ignite the dust or fumes.

Assembly

Power Supply of the Surface Laser
The measuring tool can either be operated with commercially available batteries or with a Bosch lithium-ion battery pack.
Operation with Batteries (see figure B)
Alkali-manganese batteries are recommended for the measuring tool.
For installation and removal of the batteries, the measuring tool’s height adjustment must be set to the lowest position. For this, turn the thumbwheel for height adjustment 9 in an anticlockwise direction to the stop.
To open the battery lid 7, press on the latch 6 and fold the battery lid up. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.
Always replace all batteries at the same time. Only use batteries from one brand and with identical capacity.
Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and self-discharge.
Operation with Battery Pack (see figure C)
Use only original Bosch lithium-ion battery packs with the voltage listed on the nameplate of your measuring tool. Using other battery packs can lead to injuries and pose a fire hazard.
Note: Use of battery packs not suitable for the measuring tool can lead to malfunctions or cause damage to the measuring tool.
Note: The battery pack is supplied partially charged. To ensure the full capacity of the battery pack, completely charge the battery pack in the battery charger before using it for the first time.
Use only the battery chargers listed on the accessories page. Only these battery chargers are matched to the lithium-ion battery pack that can be used in your measuring tool.
The Lithium-Ion battery pack can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery pack.
The battery pack is equipped with an NTC temperature control which allows charging only within a temperature range of between 0 °C and 45 °C. A long battery pack service life is achieved in this manner.
For the installation and removal of the battery pack 23, the measuring tool’s height adjustment must be set to the lowest position. For this, turn the thumbwheel for height adjustment 9 in an anticlockwise direction to the stop.
To insert the battery pack 23, press on the latch 6 and fold the battery lid 7 up. Slide the charged battery pack completely into the battery compartment and close the battery lid.
Operation with 1,5 Ah battery pack: In order to shut the battery lid 7, the foam damper on the inside of the battery lid must be removed.
To remove battery pack 23, press on latch 6 and fold the battery lid 7 up. Pull the battery pack out of the battery compartment.

Power Supply of the Remote Control (GSL 2 Set)
Using alkali-manganese batteries is recommended for the operation of the remote control.
To open the battery lid 20, press on the latch 21 and remove the battery lid. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.
Always replace all batteries at the same time. Only use batteries from one brand and with identical capacity.
Remove the batteries from the remote control when not using them for longer periods. When storing for longer periods, the batteries can corrode and discharge themselves.

Operation

Starting Operation of the Surface Laser
Protect the measuring tool against moisture and direct sunlight.
Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.
Avoid hard knocks to the measuring tool or dropping it. Damaging the measuring tool can cause accuracy to be compromised. Following a hard knock or fall, carry out a
check by comparing the laser lines or plumb beams with a known horizontal or vertical reference line or verified perpendicular points.
Switch the measuring tool off during transport. When switching off, the leveling unit, which can be damaged in case of intense movement, is locked.
Setting Up the Measuring Tool
Set up the measuring tool on the floor surface to be checked, ensuring that it is firmly positioned.
The leveling accuracy can be influenced by the ambient temperature. Especially temperature differences occurring from the ground upward can deflect the laser beam. As thermal layering is greatest at ground level, the measuring tool should always be set up in the center of the floor surface to be checked.
Switching On and Off
To switch on the measuring tool, slide the On/Off switch 8 to the “On” position. Immediately after switching on, the measuring tool sends laser beams out of the exit openings

  1. Do not direct the laser beam at persons or animals (especially not at their eye level), and do not stare into the laser beam yourself (not even from a distance).
    To switch off the measuring tool, slide the On/Off switch 8 to the “Off” position. When switching off, the leveling unit is locked.
    When the measuring tool is not moved or remote-controlled for approx. 30 minutes, it switches off automatically to save the batteries or the battery pack.
    After switching off automatically, switch the measuring tool off via On/Off switch 8 and then on again, if required. GSL 2 Set: After switching off automatically, the measuring tool can be switched on again by pressing any button on the remote control.
    Do not leave the switched-on measuring tool unattended and switch the measuring tool off after use. Other persons could be blinded by the laser beam.
    When exceeding the maximum permitted operating temperature of 50°C, the measuring tool switches off to protect the laser diode. After cooling down, the measuring tool is ready for operation and can be switched on again.
    Operation with battery pack: The “Electronic Cell Protection (EC P)” protects the lithium-ion battery pack against deep discharging. When the battery pack is discharged, the measuring tool is switched off by a protective circuit. When the measuring tool switches off automatically due to a discharged battery pack, switch the measuring tool off with the On/Off switch
  2. Charge the battery pack before switching the measuring tool on again. Otherwise, the battery pack could become damaged.
    Allowing the Measuring Tool to Level In
    After switching it on, the leveling function automatically compensates for irregularities within the self-leveling range of ±4°. The leveling is finished as soon as the laser beams do not move anymore.
    If the automatic leveling function is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 4° from the horizontal plane, the laser beams flash.
    Set up the measuring tool in a level position and wait for the self-leveling to take place. As soon as the measuring tool is within the self-leveling range of ±4°, the laser beams light up continuously.
    In case of ground vibrations or position changes during operation, the measuring tool is automatically leveled in again, yet, possibly to a different height when larger position changes are the case. Upon re-leveling, check if the two laser beams are aligned at the reference point (see “Aligning the Height of the Measuring Tool”, page 16 ) in order to avoid vertical errors.
    Aligning the Height of the Measuring Tool
    The measuring tool generates two laser beams that can be seen on the floor surface in front of the measuring tool for distances beyond 50 cm. The beams must be brought into alignment at this reference point, where they can initially be seen on the floor surface. For this, turn the thumbwheel for height adjustment 9 clockwise or anticlockwise, until both laser beams overlap at the reference point and only one beam can be seen.
    When the two laser beams cannot be aligned by turning the thumbwheel, the position of the measuring tool is significantly above or below the floor surface. Position the measuring tool at a different location on the floor surface with less height deviation and align the laser beams there.

Starting Operation of the Remote Control (GSL 2 Set)
Protect the remote control against moisture and direct sunlight.
Do not subject the remote control to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the remote control to adjust to the ambient temperature before putting it into operation.
The remote control remains ready for operation as long as a battery with sufficient voltage is inserted.
The signals of the remote control should reach the reception lens 4 directly from the front and inclined from above. When the remote control cannot be pointed directly against a reception lens, the working range is reduced. By reflecting the signal (e.g. against walls), the working range can be improved, even for indirect signals.
Switching the measuring tool on via the remote control after the automatic shut-off of the measuring tool is only possible when the On/Off switch 8 is still in the “On” position. Switching the measuring tool off with the remote control is not possible.

Measuring Procedure
Manual Rotation (GSL 2)
Rotate the upper part of the measuring tool to the location that you want to check. After rotating, wait until the measuring tool has leveled in again and the laser beams no longer move. Then, check if the laser beams run opaque.
Automatic Rotation (GSL 2 Set)
To check the surface, rotate the upper part of the measuring tool with the remote control. Manual rotation is not possible. The following rotation modes are available:

| Press button 19 to start fast, continuous rotation in a clockwise direction. Pressing button 19 again ends the rotation.
---|---
| Press button 14 to start fast, continuous rotation in an anticlockwise direction. Pressing button 14 again ends the rotation.
| Press button 18 to start a slow, continuous rotation in a clockwise direction. Pressing button 18 again ends the rotation.
| Press button 15 to start slow, continuous rotation in an anticlockwise direction. Pressing button 15 again ends the rotation.
| Press button 17 for a single, brief rotation step in a clockwise direction. For each further individual movement, press button 17 again.
| Press button 16 for a single, brief rotation step in an anticlockwise direction. For each further individual movement, press button 16 again.

Evaluating Measuring Results (see figures D – G)
The two laser beams indicate, whether the surface is at the same height as the reference point (see “Aligning the Height of the Measuring Tool”, page 16):

  • All points, at which both laser beams coincide exactly above each other, are at the same height as the reference point.
  • When two beams can be seen next to each other or when the laser beams are interrupted, the height of the floor surface deviates with respect to the reference point at this
    location.

To measure the deviation of the floor surface, position the laser target plate 10 at the location to be checked. Turn the laser target plate in such a manner that the lefthand laser beam coincides with the left reference line of the laser target plate. Slide the upper part of the laser target plate upward or downward, until the tip 11 of the laser target plate rests on the
location to be measured. The height deviation between the reference point and the measuring point can be read in mm via the position of the righthand laser beam on the laser target plate.
When both laser beams run apart at a constant angle on the floor surface, the floor surface is inclined.
Working Advice
Pay attention that the complete width of the laser beams coincides exactly with each other. The width of the laser beams changes with the distance.

Transporting the Measuring Tool
Handle 3 can be used for easier transport of the measuring tool. Fold the handle up as required.
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter to the eyes.
Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualization of the laser beam, but they do not protect against laser radiation.
Do not use the laser viewing glasses as sunglasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce color perception.
Recommendations for Optimal Handling of the Battery Pack
Protect the battery pack against moisture and water.
Store the battery pack only within a temperature range between 0 °C and 50 °C. As an example, do not leave the battery pack in the car in summer.
A significantly reduced working period after charging indicates that the battery pack is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning
Before any work on the measuring tool itself (e.g. assembling, maintenance, etc.) as well as when transporting and storing, remove the battery pack or the batteries from the measuring tool. The danger of injury when accidentally actuating the On/Off switch.
