SETTING TO WORK
Before using the unit for the first time, install alkaline or rechargeable batteries. Charge rechargeable batteries.
See battery section.
Position the unit horizontally or vertically (tripod mount and rubberfeet downward!) on a stable platform,
wallmount or tripod at the desired elevation. The unit recognizes automatically whether it is used horizontally
or vertically when switched on.
Press the power button 1 to turn on the unit. Self-leveling will start at once. In order to switch the unit off, press
the power button again. The unit is leveled when the leveling indicator 6 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.
After turning on the unit and after self-leveling, the unit starts with the last chosen mode. Using "set and forget"
during self-leveling after turning on the unit, the scan size and position, and rotation speed can be chosen
while the laser beam will be emitted.
If the unit is positioned beyond it´s self-leveling range of ±8%, the laser and leveling indicators will recurringly
flash quickly four times. Turn the unit of f, reposition the laser within the self-leveling range and turn it on again.
Rotation mode
By pressing the speed/rotation button 3 the unit is set into rotation mode. Line mode is stopped.
Pressing the button again, rotation speed will toggle through 600, 200, 80, 10 and 0 min
laser line will increase visibility of the rotating beam.
When pressing the buttons on the keypad, the unit may temporarily become out of level due to its
high accuracy. The motor will not rotate until it has self-leveled again.
Select the highest rotation speed (600 rpm) for use with an electronic detector (HV301).
Pointing mode
When using the pointing mode, the laser visibility will be at its highest because the entire laser energy
is focused on one point. Turn the prism by hand or press the arrow buttons 4 and 5 on the keypad to the
desired position.
During horizontal operation, by pressing the arrow buttons, the prism is moved gradually counterclockwise
or clockwise (360°).
During vertical operation, the laser point may be positioned precisely or may be adjusted parallel right- or
leftwards on a ± 8% range.
By pressing and holding the buttons, the movement of the point will be accelerated.

Line/scanning mode
By pressing and releasing the scan size button 2, the unit is set to scan mode. Rotation mode is stopped.
The unit starts at an opening angle of approx. 8 degrees. Pressing the button again increases the angle to
approx. 45, 90 and 180 degrees.
By pressing and holding the scan size button 2 a programmable scan zone can be created by turning the
prism manually from the desired start-to the desired end-point. After releasing button 2, the created line will
be performed at actual speed.
By pressing the arrow buttons 4 and 5 the scan zone may be moved clockwise or counterclockwise. By pressing
and holding the buttons, the movement will be accelerated.
When pressing the buttons on the keypad, the unit may temporarily become out of level due to its
high accuracy.
Manual mode/Single Slope mode
By pressing the 'M'/ button on the remote control or the receiver-remote control, the unit is set from automatic
self-leveling mode to Manual mode. Manual mode is indicated by the flashing (once every second) red LED 7.
In Manual mode, the Y-axis can be sloped by pressing the Up- and Down-Arrow-buttons on the unit's keypad
or the remote control. Additionally, the X-axis can be sloped by pressing the Left- and Right-Arrow-buttons
on the remote control.
By pressing the 'M'/
indicated by the flashing red 7 and green 6 LEDs (once every second). In vertical setup, pressing the 'M'/
button again switches the unit back to automatic self leveling mode. In Single Slope mode, the Y-axis can
be sloped by pressing the Up- and Down-Arrow-buttons on the unit's keypad or the remote control, while the
X-axis remains in automatic self leveling mode (e.g. when setting up sloped ceilings or drive ways). Operates
the unit in Rotation at 600 rpm, the Height change (HI) alert is still active.
button again in horizontal operation, the unit is set into Single Slope mode. This is
Self-leveling, Height change (HI) alert
Once turned on, the unit automatically levels itself in ranges of 8% (± 0,8 m / 10 m; 8 ft/100ft)). 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 600 min
Level errors > 30 mm/10 m (1-1/8inch/10ft) put the unit into alert mode because they are generally caused by
a disturbance which could lead to inaccurate measurements. When entering into alert mode, the prism stops,
the beam turns off, a warning sound is heard and the HI Warning LED 7 flashes 2x per second. Turn the unit
off and then on again. To assure your former elevation, now you have to check or arrange the exact height.

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 which 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 20 m (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 spot at the centre of the beam at wall A. Turn the entire unit
180°, let it self-level and mark the center of the laser spot 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 spot at the centre of the beam at wall B. Turn the entire unit 180°, let it self-level and mark
the center of the laser spot 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 (± 15"), the maximum difference from true level at 20 m (65
ft.) + 20 m (65 ft.) = 40 m (130 ft.) is 3 mm (1/8 inch). The highest and the lowest mark may be up to 6 mm
(1/4 inch) apart.
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.
If the visibility of the laser beam is bad, you can use a detector to transfer the heights to the walls. The accuracy
of the detector has to be regarded.

OPERATING EXAMPLES
Marking Heights
Put the instrument in horizontal mode (e.g. when using a tripod or wallmount) so that the laser beam is at the
desired height. Then either turn the prism manually to the desired area or use one of the rotation modes.
When working without a tripod or wallmount, put the instrument on a stable base and measure the height
difference between laser beam and desired height by using a ruler . After turning the prism to the desired area,
mark the measured height again.

Adjusting in Parallel
In order to measure irregularities, create right angles, align partitions in right angles or to mark vertical lines,
the direct beam (plumb beam) has to be adjusted parallel which means the laser beam has to be placed in
the same offset distance to a wall or any other reference line.
Therefore place and align the unit in vertical mode, so that the beam runs roughly in parallel to a wall or other
reference line. Measure the distance between the beam and the wall near the unit and at a certain distance.
To adjust the beam in parallel, press the line button 4 or 5 to realize the same offset distance at the unit and
far away.
The procedure for aligning an extension joint is similar. Just position the unit so that the beam runs directly
above the joint.
A long reference distance is important for accuracy. Therefore it should be as long as possible.
Right Angles/Vertical Mode
Set up the unit in vertical mode so that the perpendicular beam is parallel to a reference line (e.g. a wall). The
rotating laser beam is now at a right angle from your original point and as a vertical area available.
The best visibility is reached by using the line mode (e.g. as a perpendicular).
Transferring marks to the Ceiling - Plumb Point
The origin of the laser beam is located directly above the horizontal tripod mount and the height of the vertical
tripod mount.
In order to transfer a marked point from the bottom to the ceiling, there are center marks 13 at the lower part
of the unit's housing. Using these marks, the unit may be set up with the two axes X and Y above two crossed
chalk marks, for example.
For better installation of the unit above a mark on the floor, just mark 2 rectangular lines through
this point.
WALL MOUNT M300 (optional)
1. Nail Hole – allows you to hang the wall mount onto a nail or screw.
2. Locking Lever – opens/closes the clamp.
3. Stop Screw - stops the sliding bracket from moving beyond a set point on the wall mount. The screw can
be moved so that the center of the beam aligns with the wall molding 0.0 cm (0.0 in.) or (3.1 cm (1 ¼ in.)
4. 5/8" –11 Laser Mount – lets you connect the laser to the wall mount and holds the sliding bracket in place
after it has been positioned along the elevation scale.
5. Reading Edge – allows you to adjust the laser position appropriate for your application needs.
6. 5/8"-11 Tripod Mount – lets you connect the wall mount to a standard tripod when using in vertical mode.
7. Elevation Scale – provides graduated marks that indicate the position of the laser relative to the wall-
molding height. The adjustment range on the scale is from 3.1 cm (1 ¼ in.) above wall-molding height to
5 cm (2 in.) below it. (The „–2“ position is aligned with the horizontal centerline at the ceiling target.)
8. Lock Nut – lets you adjust the clamping force.
9. Clamp – opens/closes so that the wall mount can be attached to wall molding or floor track.

POWER SUPPLY
Installing Batteries
Remove the battery door by turning the centerscrew 90° counterclockwise. Insert batteries (or a rechargeable
battery pack) into the housing so that the negative poles are on the larger battery spiral springs.
DO NOT REMOVE RECHARGEABLE BATTERIES FROM THEIR HOLDER AND INSTALL ALKALINE
BATTERIES, SEVERE DAMAGE TO UNIT WILL RESULT IF CHARGING IS ATTEMPTED.
Install the battery door and tighten it by turning the centerscrew 90° clockwise.
A mechanical switch prevents alkaline batteries from being charged. Only the original
rechargeable batterie pack allows charging within the unit. Any other rechargeable batteries
have to be charged externally.
Operating Time
Rechargeable batteries permit an operating time (at 21° Celsius) of appr. 40 hours -HV301; 18 hours - HV301G
in rotation mode.
Alkaline batteries (AIMn) permit an operating time of appr. 90 hours - HV301; 45 hours - HV301G in rotation mode.
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 slow flashing of the battery indicator 8.
Charging rechargeable batteries
The charger requires appr. 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° and 104°F (10° 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.
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.
