2. Directions of Use
2.1 Set Up
Location  Keep the location clear of possible obstructions that could
block or reflect the laser beam.
 Place the i88R/G on stable ground. Ground vibration and
extremely windy conditions can affect the operation.
 When working in a very dusty environment place the laser
up-wind so the dirt is blown away from the laser.
Setting up on a
Tripod
 Attach the i88R/G securely to a tripod or mount on a
stable level surface.
 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.
2.2 Turning On/Off
Turning on and
off
Press the power button (f) to turn on/off the i88R/G
After turning on:
 If set within the 5° self-levelling range, the i88R/G will
self-level, once the unit has self-levelled the laser head
will start to spin emit a rotating laser beam.
 If the unit is bumped or senses interference the laser head
will stop spinning and re-level. Once unit has re-levelled
the laser head will begin to spin again, emitting a level line
 Warning - If the unit has been bumped or moved and the
laser recommences spinning the instrument may not be at
the original level position. Please recheck your RL/datum
point.
2.3 Tilt Warning System (TWS)
Description
of (TWS)
Mode
To prevent the possibility of the i88R/G giving a different reading
than is expected due to a knock or the laser being moved by a
third party the TWS function can be used and will prevent the unit
re-levelling and spinning in the event of a knock or movement.

Page | 5
Using TWS
Mode
Press the TWS button (i) (TWS on/off) to turn on the TWS.
When activated the LED (d) will light.
When the TWS is activated on the i88R/G, if the unit is
knocked or interfered with, the laser will stop spinning and the
TWS indicator light will flash. The laser will then need to be
reset by the operator before the laser will begin to spin again.
To reactivate TWS, press the TWS button again, and the
laser will re-level and begin to spin again. It is advised to
check RL/Datum point when unit re-levels.

Turn the i88R/G on and allow self-level.
 Once laser is level and spinning press the Grade slope button
(i) to activate manual mode. This will enter ‘X’ axis adjustment
mode and the ‘X’ axis indicator light (a) will and the self-
levelling function of the level will deactivate.
 Using the arrows you can now adjust the slope of the laser
beam along the ‘X’ axis to your desired slope.
 To enter a slope on the ‘Y’ axis, press the Grade Slope button
(i) again and the ‘Y’ Axis indicator light (a) will also light.
 Using the arrows you can now adjust the slope of the laser
beam along the ‘Y’ axis to your desired slope.
 To return to level mode, press the Grade slope button again,
the grade slope light will turn off and laser will self-level to level
position.
2.5 Wind Mode
Description of
Wind Mode

Step Description
1.
30m
Place the i77R on a flat, level surface or
tripod approximately 30m from a wall.
2. Align the first axis so that it is square to the wall. Allow the i77R to
self- level completely and it will begin to rotate.
3. Mark the position of the beam on the wall. (centre of the point)
4. Very carefully rotate the laser on the tripod 180° and allow it to
rotate and self-level.
5. Mark the position of the beam on the wall. (centre of the point) if
different from the original mark.
6. Align the second axis so it is flat to the wall by carefully rotating the
laser on the tripod by 90°. Allow the i77R to self-level completely.
7. Mark the position of the beam on the wall. (centre of the point) if
different from the previous marks.
8. Very carefully rotate the laser on the tripod 180° and allow it to
rotate and self level.
9. Mark the position of the beam on the wall. (centre of the point) if
different from the previous marks.
