Maintenance and Safety
• While the instrument is operating, be careful not to expose your eyes to the laser beam. Direct exposure to a
laser beam for a long time may be hazardous to your eyes. The laser beam is equivalent to a class II .
• Operate this laser so that the laser beam plane avoids impact on the eyes of vehicle drivers or pedestrians.
• Do not try to dismantle the instrument. Have it repaired by your dealer or supplier. Dismantling yourself may
worsen the problem or void your warranty.
• When attaching the instrument to a tripod, make sure the instrument is securely fixed. The tripod leg clamps
should be securely fastened. If not securely fastened or tightened, the main unit could fall off or the tripod
could fall over.
• The laser should not be stored or used in extreme temperature or during rapid temperature change. The laser
may not function properly if used out of the ambient temperature range.
• Store inside the carry case and place in a dry area not subject to vibration, dust or high moisture.
• If the storage temperature and ambient temperature for usage vary significantly, leave the laser in its case
until it can adjust to the ambient temperature.
• The laser should be transported or carried carefully to avoid impact or vibration.
• The laser should be stored in the carry case and packed with cushioning material. Always handle the laser
with care.

3. Directions:
3.1 Battery Installation
The FRE301 is supplied with a rechargeable Ni-MH battery pack that is located in the base of the unit.
It is recommended that the battery pack be completely charged before use as the FRE301 battery pack does not come
pre-charged and charging the unit while it is operating increases the charging time. The charging time when the unit is
turned off is approximately 8 hours. The operating time for the FRE301 with a new battery pack that is
at full charge is approximately 50 hours however this will decrease over time as the battery pack ages and due to the
number of charges / discharges that the battery pack has in its lifetime. Operating time may decrease and charging time
may increase based on changes in temperature where the unit is being either stored or operated.
The FRE301 is supplied with a battery charger / power adaptor in the carry case. When the FRE301 is low on power the
power indicator light will begin to flash indicating that the battery pack should be recharged as soon as possible.
Plug Hole

To charge the FRE301, insert the battery charger / power adaptor into the port on the battery pack. The light on the battery
charger /power adaptor has three stages:
- Red (Flashing)
Charger and battery are not connected.
- Red (Constant)
Battery is charging.
- Green (Constant)
Battery is charged.
Notices:
(1) Using the standard rechargeable batteries of the instrument, recharging will be finished within 8
hours.(4x5000mAh Ni-Mh batteries)
(2) Power required for the charger: Frequency: 50-60HZ; Voltage: 85-265V.
(3) Charging and using of the instrument can progress simultaneously.
(4) If keeping the instrument in storage (or Leave the instrument unused for a long time), the batteries
(dry battery or rechargeable battery) needs to be taken out.
(5) Brand-new rechargeable batteries or long-time unused rechargeable batteries need to be recharged
and discharged three times to attain the capacity required.

7. Accuracy Checking
Follow these instructions for checking axis accuracy.
7.1 Horizontal-surface Checking
1. Place the instrument at the point of 50m in front of wall (or set a scale plate at the point of 50m away from the
instrument), and then adjust the level of the base approximately to aim the X1 to the wall (or scale plate), as depicted
below:
15
2. Allow the unit to level and begin rotating. Mark the beam position on the wall or scale plate as H1.
3. Loosen the screw of the tripod, and then turn the laser 180°. Allow the unit to level and rotate, mark
the beam position on the wall or scale plate as H2.
The difference between the value of H1 and H2 should be less than 10 mm.
4. Repeat the same process to check your Y-axis beam.
Again, the difference between the values of the
two measurements should be less than 10 mm.
5. If the difference in either axis is more than 8mm, the laser should be sent to your authorized dealer for
service/calibration.
16
7.2 Horizontal-line checking.
First lay down the instrument:
-Mount the instrument on tripod between A wall and B wall. Tripod near Wall A. Distance should follow the instructions
on illustration. Switch the instrument on.
17
-After leveling, direct the laser beam onto the close wall A. Mark the centre point of the laser beam on the wall (Point I)
°
-Turn the instrument horizontally by 180 .(without changing the height).after leveling, direct the laser beam onto Wall B.
Mark the centre point of the laser beam on the opposite wall B(Point II)
18
-Without turning the instrument. Position it close to wall B by moving the tripod. Switch on the instrument and let it
leveling.
19
-After leveling, align the height of the instrument by using tripod or by underlaying, if necessary. In such a manner that
the centre point of the laser beam is projected exactly located the previously marked point II on wall B.
20
D
°
-Rotate the instrument by 180 without changing the height. Allow it to level in and mark the centre point of the laser
beam on wall A(point III).Tare care that point III is as vertical as possible above or below point I.
-The difference D of both marked points I and III on wall A amounts to the actual deviation of the plumb up beam
