Housing Nomenclature Laser head Laser window Rubberized Handle Control panel Charging port —5— 2.2. Control Panel Nomenclature Manual grades X & Y Laser head position anti-clockwise Scanning mode Laser head position clockwise Rotation speed Auto/manual Anti-drift mode Power (ON/OFF) —6— 2.3 Control Panel Operation 1. 2. 3. 4. 5. 6. 7. Beam Position: Rotates the beam clockwise or anti-clockwise when the laser head is set to a stationary dot or is in scan mode. Auto/Manual: Toggles the laser between auto leveling mode and manual mode (for set-up of manual slopes). Power (ON/OFF): Switches the unit on or off. Manual Grade: Drives a manual grade into the laser head when the unit is in manual mode. (see 3.7) Beam Scan: Puts the beam into scan mode and is used to cycle through the preset scan angles (0°, 10°, 45°, 90°, 180°, 0°). Rotation Speed: Puts the beam into rotation mode and is used to cycle through the preset rotation speeds (0, 60, 120, 300, 600, 0 rpm). (Note: When using a receiver use 600rpm) Anti-Drift: Activates the anti-drift system (see 3.6). —7— 3. Instrument Operation 3.1 Horizontal Leveling: • Place the Polar on the floor, countertop or mount it to a tripod or wallmount - suggest a flat head tripod is used. • Press the power button and allow up to 60 seconds for the unit to level. While leveling, the laser beam will flash. Once it has finished leveling it will stop flashing and the beam will begin to rotate. • The laser beam and auto/manual LED will flash if the instrument is set up outside its self-leveling range of ±5°. 3.2 Vertical Leveling: • Place the Polar on the floor or countertop using the built in trivet points or alternatively mount to a vertical mount (B-WM) and attach to a tripod. • Press the power button and allow up to 60 seconds for the unit to level. While leveling, the laser beam will flash. Once it has finished leveling it will stop flashing and the beam will begin to rotate. • The laser beam and auto/manual LED will flash if the instrument is set up outside its self-leveling range of ±5°. —8— 3.3 Rotation Speed Adjustment: Once the laser is set-up in either horizontal or vertical leveling mode, pressing the rotation speed button will cycle through the preset rotation speeds (0, 60, 120, 300, 600, 0 rpm). Slowing the rotation speed increases the visibility of the beam for interior applications. Note: for greatest accuracy when using a receiver, always use the laser in the fastest rotation speed available. 3.4 Scan Mode: Once the laser is set-up in either horizontal or vertical leveling mode, pressing the beam scan button will put the beam into scan mode and cycle through the preset scan angles (0°, 10°, 45°, 90°, 180°, 0°). Using a lower speed beam in scan mode increases the visibility of the beam for interior applications and also keeps your beam from interfering with other workers on-site when you do not require a full 360° rotating beam Note: in scan mode the beam will not be picked up properly by a receiver. —9 — 3.5 Beam Position: Once the laser is set-up in either horizontal or vertical leveling mode, if the rotation speed of the laser is slowed to 0 rpm or the laser is placed in scan mode, the positioning of the beam can be adjusted clockwise or anti-clockwise by using the relevant beam position buttons. 3.6 Anti-Drift System: Once the laser is set-up in either horizontal or vertical leveling mode, pressing the anti-drift button will activate anti-drift mode. The anti-drift LED will flash slowly when the anti-drift system is turned on. If the unit is bumped or moved out of level when anti-drift is engaged, the anti-drift LED will flash quickly and the laser will stop rotating. To deactivate anti-drift mode, press the anti-drift mode button again. 3.7 Manual Grade: • Set up the laser in horizontal leveling mode as above. • When self-leveling has completed, press the auto/manual button to enter manual mode. • Press and hold the ¡ button to drive the beam up to your desired grade in the X1 direction. — 10 — • Press and hold the ¢ button to drive the beam down to your desired grade in the X1 direction. • Press and hold the button to drive the beam up to your desired grade in the Y1 direction. • Press and hold the £ button to drive the beam down to your desired grade in the Y1 direction. Notes: • Press the auto/manual button again to Y1 enter back into automatic leveling mode. • Entered grades are not saved when the unit is turned off. The laser will always automatically self-level when turned on. (See Annex A for manual slope set-up procedure) X1 X2 Y2 — 11 — 4. Battery The Bear Polar comes equipped with a charger and inbuilt rechargeable battery but should you ever need to remove the battery pack for any reason (ie. if the unit is not going to be in use for more than two months) please use the following procedure: • Unscrew the four retaining screws in the battery pack in the bottom of the instrument with a phillips head screw driver. • Turn the unit upright while holding your hand under the base of the laser. The battery pack should drop out into your hand. To reinstall the battery pack: • Place the battery pack inside the base of the unit ensuring that the orientation of the pack is such that the contacts inside the laser’s base align with the contacts on the battery pack. • Install the four retaining screws in the battery pack and tighten them down. — 12 — When battery power is low, the power LED will flash indicating that the batteries must be charged. To charge the batteries: • Plug the mains plug of the charger into a 100-240VAC (50/60Hz) power supply. • The red LED on the charger will flash. • Plug the charge plug into the charge port on the laser. • The red LED will light solidly while the battery is charging. • When charging is complete, the red LED on the charger will flash again. • On average, a full charge will take approximately 7 hours. Note: • The instrument can still be used while it is charging. • Brand new rechargeable batteries or those that have not been used for a long Charging Port time may need to be charged and discharged several times before they attain maximum capacity. Charger — 13 — 5. Remote Control The Bear Polar comes standard with an infrared remote control. The remote can control all functions of the laser except power on/off and anti-drift mode on/off. The buttons on the remote control coincide exactly with the buttons on the control panel of the laser (refer to 2.3) and all functions are operated in the same manner. Operating distance of the remote control is up to 20m. The red LED on the remote control will flash to show that the operating signal has been sent to the laser when a key is pressed. Remote — 14 — 6. Accuracy Checking & Adjustment: The Bear model Polar is a sealed unit and is calibrated to precise accuracies at the factory. However, it is recommended that you perform a calibration check before the initial use of the laser and then from time to time to ensure that you are doing the highest quality work possible. Always check calibration if the laser has been handled roughly, dropped or loaned to your best mate. 7.1 Horizontal & Vertical Calibration Check: If possible drop by your dealer for a CAL check - usually takes around 10 minutes. (there may be a charge for this service). OR 7.1.1 Y-axis: 1. Attach the laser to a stable flat head tripod or stand at least 15m from a wall or other stable vertical surface (the target). Use a carpenter’s level to ensure the tripod head is level enough to allow the laser to be aimed in different directions with minimal re-leveling. Turn the entire laser so that either direction of the Y-axis is aimed at the target. 2. Turn the laser on in rotation mode, go to the target and find the laser beam. Make a mark at the center of the beam thickness. It is easiest to hold your pencil on the — 15 — sweeping beam line and move slightly up or down until you see that you are centered on the beam, make your mark. If conditions make the beam difficult to see, you can slow the rotation, scan the beam on the target surface or use a receiver to find the beam. 3. Turn the entire laser 180 degrees, ensuring that the height of the tripod does not change as this will affect your results. The opposite Y-axis direction should now be aimed at the target. Secure the laser, allow it to re-level and mark the laser beam on the target. 4. The difference between the two marks (if any) is double the difference between the laser’s calibration and true level for the Y-axis. Half way between these two marks is true level. Make a long mark at true level. The calibration error of the laser is the difference between either one of the original marks and true level. (eg. If the difference between one mark and true level is 1mm and your laser is 30m from the target, then the calibration error of the laser is: 1mm @ 30m). 5. If the calibration error is within the stated specifications of ±2.0mm @ 30m then no calibration is required. If the calibration is outside of this specification do not move the laser and proceed with the calibration procedure for the Y-axis outlined in 7.2.1 — 16 — 7.1.2 X-axis: 1. Follow steps 1 to 4 of procedure 7.1.1 above, substituting the X-axis for the Y-axis. 2. If the calibration error is within the stated specifications of ±2.0mm @ 30m then no calibration is required. If the calibration is outside of this specification do not move the laser and proceed with the calibration procedure for the X-axis outlined in 7.2.2 7.2 Horizontal Calibration Adjustment: 7.2.1 Y-axis: 1. Press and hold the ¡ and ¢ buttons on the laser control panel for about 3 seconds. The anti-drift LED will start flashing to indicate that the laser is in Y-axis calibration mode. 2. Use the £ or buttons to adjust the height of the beam on the target until it is at true level or within the calibration specifications of the laser. 3. Press and hold the ¡ and ¢ buttons on the laser control panel for about 3 seconds to save the calibration data and exit Y-axis calibration mode. The laser will return to horizontal leveling mode and the anti-drift LED will turn off. — 17 — 7.2.2 X-axis: 1. Press and hold the £ and buttons on the laser control panel for about 3 seconds. The auto/manual LED will start flashing to indicate that the laser is in X-axis calibration mode. 2. Use the ¡ or ¢ buttons to adjust the height of the beam on the target until it is at true level or within the calibration specifications of the laser. 3. Press and hold the £ and buttons on the laser control panel for about 3 seconds to save the calibration data and exit X-axis calibration mode. The laser will return to horizontal leveling mode and the auto/manual LED w ill turn off. Note: If the laser is turned off without saving the calibration data, the calibration of the laser will not change and you must begin the entire calibration procedure again - NOT FUN. — 18 — 7.3 Vertical Calibration Check: 1. Set the laser up in vertical leveling mode as per procedure 3.2 2. Set up a plumb line in front of a wall approximately 10m from the laser. 3. Physically move the laser to aim the rotating beam at the plumb line. 4. Check if the laser accurately follows the plumb-line. If the beam deviates from the plumb line do not move the laser and proceed with the calibration procedure for the vertical axis outlined in 7.4 7.4 Vertical Calibration Adjustment: 1. Press and hold the ¡ and ¢ buttons on the laser control panel for about 3 seconds. The anti-drift LED will start flashing to indicate that the laser is in vertical calibration mode. 2. Use the £ or buttons to adjust the angle of the beam until it no longer deviates from the plumb line. 3. Press and hold the ¡ and ¢ buttons on the laser control panel for about 3 seconds to save the calibration data and exit vertical calibration mode. The laser will return to vertical leveling mode and the anti-drift LED will turn off. Note: If the laser is turned off without saving the calibration data, the calibration of the laser will not change and you must begin the entire calibration procedure again. — 19 — Annex A: Setting up for a manual grading application: Notes: • For the following procedure it is recommended that the remote control is used to adjust the grade of the laser. This will ensure adjustments can be performed quickly and accurately. • Ensure the staff is held vertical during all readings. If your staff does not have a bubble then move the staff backward and forward toward the beam and use the smallest reading for your observations. • For best accuracy use the GENNO-ROD (see page: 27) • Warning! Do not disturb the setup of the laser while taking elevation readings. The laser is completely manual in this mode and any shifts will result in movement of the laser plane. This method of creating a slope/grade is not recommended for precision applications. Bear Scientific are not responsible for any mishaps that may result by following the process described below. 1. Setup the Bear Polar in horizontal mode and rotate the unit in such a way to align the X and Y axes with the direction of the desired slopes. 2. Turn the laser on and allow it to self-level. 3. Establish a point (Point A) at a known horizontal distance along the desired run of the axis in which you wish to set-up a grade. (Note: The point should be set at an easily calculable distance to make measurements and calculations easier. Example: 10 or 20 metres) 4. Calculate the Height Differential for your desired slope/grade as per the following formula: Height Differential = (slope %) x (distance) (See examples 1 & 2 below) 5. Take a “level” reading at Point A. 6. Add the “level” reading to the Height Differential to determine the “slope” reading you are trying to establish at Point A — 20 — (Note: it is best to use the remote control for the next 2 steps but you can gently press the buttons on the laser control panel) 7. 8. 9. Press the auto/manual button to enter manual mode. Use the manual grade arrow buttons to tilt the plane of light (as per chapter 3.7) until the “slope” reading at Point A is equal to the reading calculated in point 6 above. Perform steps 3 to 8 in the opposite axis for dual grade applications. Note: If you do not have a staff to take an initial “level” reading, instead of performing steps 5, 6, & 8 above, simply make a “level” mark on a stake at Point A and then tilt the plane of light as in point 8 above until the difference between the “slope” reading at Point A and the original “level” reading at Point A is equal to the Height Differential as calculated in point 4 above. If using a Genno-Rod, you can follow the same principle as long as the Height Differential is less than 0.500m. Simply set the “level” reading as your zero datum point on the cut & fill side of the Genno-Rod at Point A and then tilt the plane of light as in point 8 above until the difference between the “slope” reading at Point A and the original “level” reading at Point A is equal to the Height Differential as calculated in point 4 above. 9. Ensure the Genno Rod is truly vertical (use inbuilt bubble) otherwise grades will be incorrect. Example 1: You desire a positive 2% slope and your level reading is 1.563m on a staff that is 10m from your laser. Eg: +2% Slope with Point A 10 metres from the laser. (Note: 2% = 2/100) Height Differential = (slope %) x (distance) = (2%) x (10m) = (2/100) x (10m) = 0.200m To establish your required “slope” reading on the staff add the Height Differential to the original “level” reading: Required “slope” reading on staff = original “level” reading + Height Differential = 1.563m + 0.200m = 1.763m — 21 — — 22 — Example 2: You desire a negative 1.5% slope and your level reading is 1.459m on a staff that is 20m from your laser. Eg: -1.5% Slope with Point A 20 metres from the laser. (Note: -1.5% = -1.5/100) Height Differential = (slope %) x (distance) = (-1.5%) x (20m) = (-1.5/100) x (20m) = -0.300m To establish your required “slope” reading on the staff add the Height Differential to the original “level” reading: Required “slope” reading on staff = original “level” reading + Height Differential = 1.459m + (-0.300m) = 1.459m – 0.300m = 1.159m — 23 — 7.
