Thank you for purchasing the Fukuda FRE-301R RED beam, rotary laser kit.
These instructions are intended to explain the quick basics to operating this
equipment. Please read them carefully.
For any more information, or if the laser requires calibration or repair; then
please contact our Service Department on Tel. [phone].

Power source:
This is a special battery pack located in the base of the laser. Remove & refit
via a central screw - finger tight (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 40 hrs of continuous use. It takes 4 to 5 charge/discharge cycles
for these battery packs to reach their maximum capacity.
Important: Do NOT allow battery to go completely dead before recharging.
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 rubber protected socket (located in the corner / base of 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 still recommend a full 6 hour charge.
The FRE-301R 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 5 - 6 hours.
A Spare Battery holder is an optional extra & 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-301R 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 IP54.
Controls:
Power ON/OFF is via the black button. The laser takes approx. 20 seconds to
auto level (possibly fine setting again) & then the head rotates continuously
to project a visible, red laser beam. The rotational speed is variable in four
increments. Adjust head speed using the yellow speed control button (right
hand side in centre) & when pressed, it stops the red dot then increases the
head's rotational speed in four steps up to a 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-301R @ its
maximum speed of 600rpm, which gives the best working range when used
with the supplied Laser Detector. Even with its bright Red beam, a detector
will still be required for most outdoor work.
SCAN function - for Interior setting-out:
The top button on the right of the keypad is the Scan function. The User can
set a Dot, or 10, 45, 90, 180 degree lines as required & use the two buttons
(top left hand side of the keypad) to move these "lines" around the room.
AS THIS LASER AUTO LEVELS BOTH HORIZONTALLY & VERTICALLY,
all the control settings above operate in either mode. (Vertical leveling,
with the laser positioned on its side, is often referred to as "Laydown")
Grading:
This is a DUAL GRADE facility laser level. This means that the FRE-301R can
be switched to "Manual" (to over-ride the level sensors) and then the User
can set a grade (incline/slope) in the X axis only, Y axis only or both together.
The max. settable slope is an approx. fall of 1m over 10m.
For X & Y alignment, please see the case 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-301R then auto levels. Press the "Manual"
button on laser's keypad (bottom left hand side) & the green LED illuminates.
Using the left & right Arrow buttons, set the % slope (fall) required - as
measured on your staff. The same buttons can be found on the Remote
Control.
To return to Auto level, switch the Manual button to OFF (green LED turns
off). The Laser will wait to find true level, then automatically restart, self-
levelled.
Setting Y axis slope -
This sets a grade in the Y axis.
Procedure – switch ON; the FRE-301R then auto levels. Press the "Manual"
3

button on laser's keypad (bottom left hand side) & the green LED illuminates.
Using the up & down Arrow buttons, set the % slope (fall) required - as
measured on your staff. The same buttons can be found on the Remote
Control.
To return to Auto level, switch the Manual button to OFF (green LED turns
off). 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 use all four arrow buttons - as required.
Automatic Drift System (ADS):
Operated via bottom, right-hand yellow button, showing a "picture of a tilted
instrument".
Once the FRE-301R is ON and rotating in the auto (self) levelled mode, the
automatic drift system can be activated. Press the button & the green LED will
flash continually. ADS is now ON.
If the Laser is knocked or caught by a gust of wind for example, the laser
head will stop rotating and the green ADS LED will flash quickly in alarm
condition. Check all is OK; press the ADS button again & the laser will reset to
AUTO level.
IMPORTANT NOTE: The ADS function cannot be set when Grading.
Remote Control & Laser Detector:
(Remote Control is pictured on the left)

Remote Control
Fit the supplied 2pc x AA alkaline batteries, taking care with correct polarity.
The Remote’s keypad can set the following functions:
1. Rotating speed in increments; slow for Indoors, fast (max) for Outdoors.
2. Scan angles in increments.
3. Scan line position around the room.
4. Auto / Manual (grade) settings via top middle button.
5. Four ARROW buttons to set required X/Y grades.
TIP - 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.
Laser Detector
Fit the supplied 9V battery, polarity marked. Power up via ON/OFF button.
The top button switches the sounder' volume ON or OFF - if required.
The middle button sets coarse (+/-2mm) or fine (+/-1mm) red pick-up
window resolution.
A rear LCD repeats the main front display.
Note: the case markings & setting notches.
You can use the detector with or without its staff mounting bracket.
Detector Procedure – face towards rotating laser & "find" rotating laser
beam via the red 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-301R 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 2 laser operating safety procedures. See main Manual.
Display a Laser Safety Notice in the work area.
General Advice:
This is an accurate measuring device - so to give good service, look after it!
Prevent the FRE-301R from receiving severe knocks, bangs or vibration.
Store the laser & its accessories in the supplied carry case.
If wet, dry before storing & keep in storage temps between 5-30 deg C.
Remove all batteries before long term storage, to prevent internal damage.
