Allowing the Tool to Level In

After switching on, the leveling function

automatically compensates irregularities

within the self-leveling range of ±4º. The

leveling is finished as soon as the laser

beams do not move any more.

If the automatic leveling function is not

possible, e.g. because the surface on

which the tool stands deviates by more

than 4º from the horizontal plane, the laser

beams flash.

Set up the tool in level position and wait

for the self-leveling to take place. As

soon as the tool is within the self-leveling

range of ±4º, the laser beams light up

continuously.

In case of ground vibrations or position

changes during operation, the tool

is automatically leveled in again, yet,

possibly to a different height when larger

position changers are the case. Upon

re-leveling, check if the two laser beams

are aligned at the reference point (see

“Aligning the Height of the Tool”, page 11)

in order to avoid vertical errors.

Aligning the Height of the Tool

The tool generates two laser beams that

can be seen on the floor surface in front

of the tool for distances beyond 1-foot

7-3/4-in (50 cm). The beams must be

brought into alignment at this reference

point, where they can initially be seen

on the floor surface. For this, turn the

thumbwheel for height adjustment 9

clockwise or counter-clockwise, until both

laser beams overlap at the reference point

and only one beam can be seen.

When the two laser beams cannot be

aligned by turning the thumbwheel, the

position of the tool is significantly above or

below the floor surface. Position the tool

at a different location on the floor surface

with less height deviation and align the

laser beams there.

Initial Operation of the Remote Control

The remote control remains ready for

operation as long as a battery with

sufficient voltage is inserted.

The signals of the remote control should

reach the reception lens 4 directly from

the front and inclined from above. When

the remote control cannot be pointed

directly against a reception lens, the

working range is reduced. By reflecting

the signal (e.g. against walls), the working

range can be improved, even for indirect

signals.

Switching the tool on via the remote

control after automatic shut-off of the tool

is only possible when the On/Off switch

8 is still in the “On” position. Switching

the tool off with the remote control is not

possible.

Automatic Rotation

To check the surface, rotate the upper

part of the tool with the remote control.

Manual rotation is not possible.

The following rotation modes are

available:

Press button 19 to start fast,

continuous rotation in clockwise

direction. Pressing button 19

again ends the rotation.

Press button 14 to start fast,

continuous rotation in counter-

clockwise direction. Pressing

button 14 again ends the rotation.

Press button 18 to start slow,

continuous rotation in clockwise

direction. Pressing button 18

again ends the rotation.

Press button 15 to start slow,

continuous rotation in counter-

clockwise direction. Pressing

button 15 again ends the rotation.

Press button 17 for a single,

brief rotation step in clockwise

direction. For each further

individual movement, press button

17 again.

Press button 16 for a single,

brief rotation step in counter-

clockwise direction. For each

further individual movement, press

button 16 again.
