POWER SUPPLY
Before using the unit for the first time, install alkaline or rechargeable batteries. If Ni-Cads are used, first recharge the batteries. See battery section.
The Ni-Cad and Ni-MH batteries may contain small amounts of harmful substances.
Be sure to charge the battery before using it for the first time, and after not using it for an extended length of time. Charge only with specified chargers according to device manufacturer's instructions.
Do not open battery, dispose of in fire or short circuit; it may ignite, explode, leak or get hot causing personal injury.
Dispose in accordance with all applicable federal, state, and local regulations.
Keep the battery away from children. If swallowed, do not induce vomiting. Seek medical attention immediately.
Installing Batteries
Remove the battery door by turning the center screw 90^ counterclockwise. Insert batteries (or a rechargeable battery pack) into the housing so that the negative poles are on the bigger battery spiral springs.
Install the battery door and tighten it by turning the center screw 90^ clockwise.
A mechanical switch prevents alkaline batteries from being charged. Only the original rechargeable battery pack allows charging within the unit. Any other rechargeable batteries have to be charged externally.
Operating Time
Rechargeable batteries permit an operating time of approx. 45 hours in rotation.
Alkaline batteries (AIMn) permit an operating time of approx. 90 hours in rotation.
The following factors reduce the operating time:
- frequent self-leveling due to wind or vibration;
- extreme temperatures;
- old rechargeable batteries or rechargeable batteries with memory-effect;
- using batteries of different capacities.
Remove all batteries at the same time. Never use batteries with different capacities. Only use new (charged) batteries (rechargeable).
Low voltage is indicated by the slow flashing battery indicator (5).
Charging the batteries
The charger requires approx. 10 hours to charge empty rechargeable batteries. For this charging, connect the plug of the charger to the recharge jack of the unit. New or long-time out-of-use rechargeable batteries reach their best performance after being charged and recharged five times.
The batteries should only be charged when the laser is between 50^ F and 104^ F (10°C to 40°C). Charging at a higher temperature may damage the batteries. Charging at a lower temperature may increase the charge time and decrease the charge capacity, resulting in loss of performance and shortened life expectancy.
HOW TO USE THE LASER
Laser Setup
Position the unit horizontally (tripod mount and rubber feet downward!) on a stable platform, wall mount, or tripod at the desired elevation.
Press the power button (1) to turn on the unit. The LEDs (3, 4 and 5) are turned on for 3 seconds. Self-leveling will start at once. The unit is leveled when the leveling indicator (3) is no longer flashing (once every second). The rotor will not spin until the unit is leveled. For the first five minutes after the laser self levels, the LED lights solid then flashes every four seconds to let you know the laser is still level.
In order to switch the unit off, press the power button (1) again.
If the laser is positioned beyond its self-leveling range of ± 8% , the manual and leveling indicators flash simultaneously and a warning sound is emitted. Reposition the laser within its self-leveling range.
Self-leveling, Height Change (HI) Alert
Once turned on, the unit automatically levels itself in ranges of 8% ( ± 0.8 ~m / 10 ~m ). In order to recognize the leveling process at the measuring area and in order not to mark faulty heights during this operation, the rotation stops.
Once leveled, the unit constantly monitors its level condition. The height change (HI) alert is activated 5 minutes after self-leveling was performed and the laser is rotating at 600min^-1 .
Level errors >30~mm / 10~m put the unit into alert mode because they are generally caused by a disturbance that could lead to inaccurate measurements. When entering into alert mode, the prism stops, the laser beam turns off, a warning sound is heard and the HI Warning LED (4) flashes 2× per second. Turn the unit off and then on again. To ensure your former elevation, now you have to check or arrange the exact height.
Manual Mode/Single Slope Mode
When you press the 'M' button (2) on the laser, the remote control, or the receiver-remote control, the laser is set from automatic self-leveling mode to Manual mode. Manual mode is indicated by the flashing (once every second) red LED (4). In Manual mode, the Y-axis can be sloped by pressing the Up- and Down-Arrow buttons on the remote control. Additionally, the X-axis can be sloped by pressing the Left- and Right-Arrow buttons on the remote control.
When you press the 'M' button again on the remote control, the laser is set into Single Slope mode. This is indicated by the flashing red (4) and green (3) LEDs (once every second). In Single Slope mode, the Y-axis can be sloped by pressing the Up- and Down-Arrow Buttons on the remote control, while the X-axis remains in automatic self leveling mode (e.g. when setting up ramps or drive ways). The Height change (HI) alert is still active.
Pressing the manual button at the laser or remote control again, changes the laser back to automatic self-leveling mode as indicated by the flashing green LED (3).
Determining the Height of Instrument (HI)
The height of instrument (HI) is the elevation of the laser's beam.
The HI is determined by adding the grade-rod reading to a benchmark or known elevation.
Set up the laser and place the grade rod on a job-site benchmark (BM) or known elevation.
Slide the receiver up/down the grade rod until it shows an on-grade reading.
Add the grade-rod reading to the benchmark to determine the height of instrument.
Example:
Benchmark = 30.55 m (100.23 ft)
Rod reading = +1.32m(+4.34ft)
Height of instrument = 31.87 m (104.57 ft)
Use this HI as a reference for all other elevations.
Marking Heights
Set up the laser in horizontal mode (e.g., using a tripod or wall mount) so that the laser beam is at the desired height.
When working without a tripod or wall mount, set up the laser on a stable surface and measure the height difference between laser beam and desired height by using a ruler and mark the measured height again.
Vertical Application
Level the tripod and allow the laser to level in automatic self-leveling mode.
Push the manual mode button and change the laser's position on the tripod for vertical alignment by using the vertical mounting thread.
Rotate the laser until the vertical laser plane aligns with the receiver's on-grade position.
In order to avoid offset errors, the receiver should be used close to the elevation where the laser has been set up.
If a remote control is available, the up and down arrow buttons can be used for fine adjustments.
LEVELING ACCURACY
Influences on the leveling accuracy
The overall accuracy of the unit can be influenced by many factors:
- factory accuracy;
temperature of the unit; - ambient influences like rain, wind and temperature.
The factor that influences on the unit's accuracy most is the ambient temperature. Vertical differences in temperature near the ground can divert the laser beam, similar to the heat waves seen on hot asphalt streets.
This factor also applies to all optical measuring devices such as automatic levels and theodolites.
Accuracy Check
To ensure job-site accuracy, you need a distance of 20m (65 feet) between two walls A and B, where you will execute 4 measuring operations on a tripod as follows (transit measurement).
Set the unit horizontally on a tripod near wall A and switch it on with the plus X-axis pointing towards wall A. After the unit is level, mark the height of the laser beam using a receiver at wall A. Turn the entire unit 180^ , let it self-level and mark the center of the laser beam at wall B.
Now, place the unit near wall B with the plus X-axis pointing towards wall B. After the unit is level, mark the height of the laser beam at wall B. Turn the entire unit 180^ , let it self-level and mark the center of the laser beam at wall A. The difference (h) of the marked points at wall A shows the deviation.
If the unit is within its working accuracy limits (± 20^ ) the maximum difference from true level at 20m (65 ft.) + 20m (65 ft.) = 40 m (130 ft.) is 4 mm (3/16 inch).
Repeat the above steps for "minus X " and for "plus-" and "minus Y ", so that a measurement for all four axes of the unit have been performed.
The accuracy of the detector has to be regarded.
PROTECTING THE UNIT
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.
CLEANING AND MAINTENANCE
Dirt and water on the glass parts of laser or prism will influence beam quality and operating range considerably. Clean with cotton swabs.
