1.3 Function The instrument is equipped with a semi-conductor diode with wavelength of 635nm on the red beam models and 532 on the green beam model. The laser beam is clearly visible, and the laser module rotates freely to form a laser scanning surface.
2. Basic Operation 2.1 Standard Set-up Leveling (see dia over page) Place unit on tripod and roughly set up so that the instrument is within 5% of level. Switch the unit on (d). The unit will then level itself and the diode will emit a beam and commence spinning.

2. Basic Operation cont: The receiver has two settings; a course and a fine setting. The band width and the audio volume can be adjusted using the receiver’s buttons. Standard Leveling Set-up When set up the instrument will create a laser beam across the entire work site to a radius of 250m and the receiver will give a signal in all points within the instruments range...
3. Manual Grade Operation The instruments have an incorporated grade slope function to 5º. For the 88R and 88G this is a dual direction in X and Y axis. This allows for the following tasks to be performed; Sloped concrete slabs, drainage slope, ceiling and grid slopes, fencing slopes.

Manual Grade Operation cont: Level setting Slope setting 3.3 Dual Grade Sloping – (88R & 88G only) Used for areas where a fall is made simultaneously to a point 90º to the other axis. Ideally, site instrument to one corner of the worksite. Set Y axis as shown.
4. Scan Mode Operation (88R & 88G only) The scan mode function allows the laser beam to emit only in a restricted radius. This function is useful for; - Internal layout work where work is being carried out in single runs or sections i.e. wall or ceilings - On restricted sites internal or external where other laser or electrical equipment may be in use - On busy sites where eye safety with other workers may be...

5. Vertical Function – 88R & 88G only The vertical function allows for the instrument to be laid horizontally and a vertical line is emitted. This function is used for; - Alignment of formwork or pipeline runs in external situations - Alignment of internal wall, floor and ceiling layout - In conjunction with the plumb spot beam, which is always 90º...
Determine datum point at end of run with the receiver. Instrument is now set to give a straight laser beam over the full length of the run. Outdoor vertical function 6. Batteries The instrument is powered by 4 DC4.8-6V Nimh rechargeable batteries that allow for approximately 20 hours continuous use in standard conditions (20º-25º) Alternatively you can use the alkaline battery pack supplied.
In some instances a car charger accessory kit is an advantage. 7. Checking Accuracy Your Imex instrument has been pre-set and calibrated for accuracy before dispatch and should perform within the stated accuracy tolerance in standard conditions. However if the instrument is knocked, poorly transported or mistreated in any way the accuracy may be compromised and unit may need re-calibration.

8. Trouble Shooting Problem Possible Cause/Solution Out of level - Check that instrument is within 5ºof alert – unit won’t level, before switching on self level - Check that manual level switch is not on - Check that unit hasn’t been bumped or moved Low battery light - Re-charge batteries...
9. Warranty Service and Care 9.1 Warranty The Imex rotating laser range is covered with a 5 year warranty as detailed on the warranty form. For registration please visit: www.imexlasers.com 9.2 Service and Calibration It is recommended that in general use, laser equipment should be calibrated by a registered service centre every 12 months.
