INSTRUCTIONS
from Laser Levels Online www.laser-level.co.uk Tel: 01246 269777
Thank you for purchasing the FRE-208 TRUE GRADE, Rotary laser level kit.
These Instructions are intended to explain the quick basics to operating this
equipment. We also include with this kit a useful data sheet: “Gradient
Conversion Chart” to convert gradients to percentage grade.
If you need any more help/advice or the instrument requires calibration or
repair, then please contact our Service Dept on tel. 01246 269 777.
We would be pleased to help.
Power source:
This is a special battery pack located in the base of the laser. Remove & refit
via a central screw - its finger tight, so no tools are required.
It contains 4pc x "sealed for life" Ni-MH type C, 4000mAh, 1.2V cells. Please
note that this battery pack can be charged either in or outside of the laser.
The mains Charger (supplied) will charge most batteries in around 7 hours to
give around 20hrs of continuous use. It takes 4 to 5 charge/discharge cycles
for these battery packs to reach their maximum capacity.
1
Mains Charger:
The general procedure to adopt is use the laser during the day & charge-up
overnight. You cannot damage the system by "over-charging" the batteries.
When plugged into a 230V mains supply, the red LED flashes every 1 sec.
Connect to the front mounted socket on the laser (or direct to the battery
pack) & this LED should be ON continuously:
ie. Red LED = charging; Green LED = sufficient charge to operate.
Even though the Green light is ON, we recommend a full 6-8 hour charge.
The FRE-208 can be operated with the charger connected to the mains
supply, if required. On receipt of your new laser, we suggest charging the
batteries fully for 6 to 8 hours.
A Spare Battery holder is also included - to be used as a back-up power
source.
Four type C, 1.5V Alkaline batteries can be used instead or in an emergency;
but do NOT attempt to recharge them, otherwise serious damage will occur.
Positioning the Laser:
Mount the FRE-208 on a generally level, firm surface or 5/8” threaded Tripod.
To operate correctly, this surface must be within +/-5 deg of true horizontal.
The laser can be used Indoors or Outdoors, where it is waterproof to IP55.
Controls:
Power ON/OFF is via the green button. The LCD screen illuminates; laser
takes 15 to 30 seconds to auto level & then the head rotates & projects a
visible red laser beam. The rotational speed is shown on the display together
with the battery charge level.
The white speed control button (just above the green button), when pressed,
stops the red dot then increases the head's rotational speed in 4 steps up to a
2
maximum speed of 600rpm.
For Interior work we suggest using slower speeds, where the laser beam is
easier to see by eye; but for Exterior Groundworks – run the FRE-208 @ its
maximum speed of 600rpm, which gives the best working range when used
with the supplied FRD400R Laser Detector.
SCAN function - for Interior work:
The second button up on the right of the keypad is the Scan function. The
User can set a static dot, or 10, 45, 90, 180 degree lines as required & use
the two buttons above to move the "laser line" position around the room.
AS THIS LASER AUTO LEVELS BOTH HORIZONTALLY & VERTICALLY,
all the control settings above operate in either mode.
Grading:
This is a TRUE DUAL GRADE laser level. This means that the FRE-208 can
be switched to "Manual" (red button "G" to over-ride the level sensors) and
then it is very easy for the User to set a grade (incline/slope) in the X axis
only, Y axis only or both together.
The max. settable slope range is +/- 10.00% ie. 1:10
For X & Y alignment, please see the embosed markings on the TOP of the
laser body where an arrow points in the direction of the axis being set.
Setting a single axis slope -
This sets a grade in the X axis.
Procedure – switch ON; the FRE-208 then auto levels. Press the red "G"
button on the Remote Control or laser's keypad & the "X" flashes on the
screen. Using the top two right hand buttons, set the % gradient value
required.
The same buttons can be found on the Remote Control. Press the X/Y button
TWICE and the laser will adjust to this angle of slope, then rotate.
To return to Auto level, switch the laser OFF & ON again via the green button,
to reset the % values to zero. The Laser will wait to find true level, then
automatically restart, self levelled.
3
Setting Y axis slope -
This sets a grade in the Y axis.
Procedure – switch ON; the FRE-208 then auto levels. Press the red "G"
button on the Remote Control or laser's keypad & the "X" illuminates on the
screen.
Press the X/Y button ONCE only to scroll down to a flashing "Y". Using the top
two right hand buttons, set the % gradient value required.
The same buttons can be found on the Remote Control. Press X/Y button
ONCE again and the laser will adjust to this angle of slope, then rotate.
To return to Auto level, switch the laser OFF & ON again via the green button,
to reset the % values to zero. The Laser will wait to find true level, then
automatically restart, self levelled.
Setting both X & Y axis slope (dual grade) -
Proceed as above, but enter values for both X% & Y%
MANUAL Grading:
The USER has the option of operating the FRE-208 in Manual grading mode,
as follows:
1. Mount the laser on a firm surface, switched OFF.
2. Observe the symbols on the green power button. Normal operation is a
single press - for TRUE grade use. The "Hand" symbol denotes MANUAL
grading.
3. Press and hold the green power "Hand" button for 3-5 secs. A "Hand"
symbol is shown on the display. To switch Manual operation, OFF - a single
press of the green button is required.
4. With the "Hand" symbol ON, press X/Y button once – “X” is shown on the
display. (Also note the X & Y direction markings on the laser's top black
cover.)
5. Press either the + or - buttons to tilt (grade) the spinning beam, manually,
in the “X” axis.
6. Press the X/Y button again, if you require grading in the “Y” axis as
well. The FRE-208 can single or dual grade, as required.
7. Expect to grade to at least 1m over a distance of 10m ie. 1 in 10 or 10%.
8. To revert back to normal operation, press the green button again. The
“Hand” symbol goes off.

9. Please note, in normal TRUE grade operation, the USER can change to
MANUAL, again by simply pressing and holding the green button for 3-5 secs.
Automatic Drift System (ADS) / often called a Bump sensor:
Operated via bottom, right-hand white button, showing a "picture of a tilted
instrument". nb. its not an option found on the Remote Control.
Once the FRE-208 is ON and rotating in the auto (self) levelled mode, the
automatic drift system can be activated. Press the button & TILT will be
displayed on the screen. ADS is now active.
If the Laser is knocked or caught by a gust of wind for example, the laser
head will stop rotating and an audible alarm sound to warn the User of the
problem.
Check all is OK, press the ADS button again & the laser will reset back to
AUTO level.
IMPORTANT NOTE: The ADS function cannot be set when Grading.
RADIO Remote Control & Laser Detector:
Radio Remote Control...
Fit the supplied 2pc x AA alkaline batteries, taking care with correct polarity.
Switch ON. The LCD shows rotational speed, scan angle & battery life.
The Remote’s keypad can set the following functions:
1. Rotating speed in increments; slow for Indoors, fast (max) for Outdoors.
2. Scan angles & position around the room.
3. Auto / Manual (grade) setting via the red "G" button.
5
4. X/Y button to set required grade axis, then +/- button to adjust the %
value.
In fact, it is often better to use the Remote Control rather than the
instrument's keypad, because, then you do not disturb the laser's sensitive
mechanism.
FRD400R Detector...
Fit the supplied 9V battery, polarity marked. Power-up via red ON/OFF button.
The middle button switches the sounder ON or OFF, & volume - if required
The right hand button sets coarse (+/-2mm) or fine (+/-1mm) red pick-up
window resolution.
A rear LCD repeats the main front display.
Note the set-level case markings & notches.
You can use the detector with or without its staff mounting bracket.
Detector Procedure – face towards rotating laser & "find" the rotating laser
beam via the pick-up window.
If the sun is low in the sky & shining into the red window, shield it with a
cupped hand to prevent false readings. Positioning the FRE-208 itself in full
sun is no problem, but the detector window can in some instances, be
affected by direct bright sunlight or reflections. So please take extra care!
SAFETY PRECAUTIONS:
Comply with class 3A laser operating safety procedures.
Display a Laser Safety Notice in the work area.
