All drilling must be undertaken by a suitably trained engineer.
Use personal protective equipment, such as dust mask, eye protection and safety shoes.
Use the drill in accordance with the drill manufacturer’s instructions.
Note that the optional mounting plate can provide a base which can be permanently installed on a vessel, making
the process of mobilising and demobilising the Merlin LT itself much simpler: see section 3.6.1.
Use M5 countersunk bolts to secure the mounting plate to the vessel. Position the mounting plate so that the
reference lines are parallel and perpendicular to the vessel’s centre line.
Use M8 bolts to secure the Merlin LT base plate directly to the predrilled holes in the mounting plate.
4.1.3 Selecting a survey angle for the Merlin LT
There are three vertical angles at which the Merlin LT laser can be positioned. Changing the vertical angle can help
to optimise the point cloud produced by the Merlin LT, specifically for your operation.
To set the desired vertical orientation, unscrew the two vertical locking studs - one on each side of the A-frame – to
free the vertical pivot.
With both locking studs undone, move the Merlin LT to the desired vertical angle.
Make sure that the vertical locking studs are in the correct lock position, then retighten them to secure the Merlin
LT in place. No tooling should be used to tighten the locking studs – finger tight is adequate.
Do not attempt to alter the vertical angle when the Merlin LT laser is rotating. This could cause
damage to the Merlin LT system and/or injury to the operator.
Once the locking studs are released the Merlin LT unit is free to pivot around the pivot point on the
A-frame. Take care to avoid trapping fingers or clothing when altering the unit’s vertical location.
