1.6.2 Imex 66R Rotating Laser
General
The rotating laser built into the product produces a visible laser beam which
emerges from the rotating head.
The laser product described in this section is classified as laser class 2.
These products are safe for momentary exposures but can be hazardous for
deliberate staring into the beam. The beam may cause dazzle, flash-blindness and
after-images, particularly under low ambient light conditions.

2 Description of the System
2.1 System Components
General Description
The 66R is a laser tool for general construction and levelling applications such as
Setting forms
Checking grades
Controlling depths for excavations
If set up within the self-levelling range, the 66R automatically levels to create an
accurate horizontal plane of laser light.
The head will rotate immediately and the green LED on the front will start to flash.
Once the LED has stopped flashing the laser is level and ready for use.
The Bump Stop function can also be used and protects the 66R against changes in
elevation caused by movement of the tripod to ensure accurate work.
Components
The 66R Rotating laser comes with:
Hard carry case
66R Rotating Laser with rechargeable batteries
Receiver with bracket
Spare batteries
Spare battery holder
Battery charger
Instruction manual
Options for a complete kit:
Tripod
Measuring Staff

2.2 Set Up
Location
Keep the location clear of possible obstructions that could block or reflect
the laser beam.
Place the 66R on stable ground. Ground vibration and extremely windy
conditions can affect the operation.
When working in a very dusty environment place the 66R up-wind so the
dirt is blown away from the laser.
Setting up on a
Tripod
Attach the 66R securely to a tripod or mount on a
stable level surface.
Always check the tripod before attaching the 66R to
make sure all screws, bolts and nuts are tight.
If a tripod has chains, they should be slightly loose to
allow for thermal expansion during the day.
Secure the tripod on extremely windy days.

3.2 Turning on and off the 66R
Turning on and off
Press the power button (a) to turn on/off the 66R
After turning on:
If set within the 5° self-levelling range, the 66R will start to rotate, the
indicator lights will flash and the unit will automatically level to create an
accurate horizontal plane of laser light.
Once levelled, the indicator lights will stop flashing and remain on.
Periodically the lights may flash for a short period of time as the unit self-
checks.
If the Bump-stop function is on then the 66R will take about a minute to self-
level before the indicator lights remain solid. If the unit is then knocked the
laser will turn off and need to be reset by the operator.
3.3 Bump Stop
Description of
Bump Stop Mode
To prevent the possibility of the 66R giving a different reading than is expected due
to a knock or the laser being moved by a third party the Bump Stop function can be
used and will turn off the unit in the event of a knock or movement.
Turning Bump Stop
Mode on and off
Press the Bump Stop button (c) (Bump-stop on/off) to on or off the Bump Stop
function. When activated the LED will light.
If the Bump-stop function is on then the 66R will take about a minute to self-level
before the laser is activated. If the unit is then knocked the laser will turn off and
need to be reset by the operator.
