Can the laser be locked to produce an angled line, e.g. For a stair handrail


  • Posted by Laser Levels Online - Support on Thursday 7th of December 2017

    Hello Chris

    Yes, the Stanley X3R can set inclines eg. for stair handrails but its not "locked" as such.

    The laser will not operate with the the transit lock is latched.

    Your procedure would be... unlock the transit latch & switch on the appropriate laser beam. Incline the laser body to the required angle to project laser line.

    The "laser line" will quickly flash on/off every 5 secs to warn you that its not self leveled but its still very easy to mark out.

    Additionally, a red LED gives a matching warning on the keypad.

    In short, yes you can set inclines.

    Best regards

What is the recharging time for FatMax X3R?


  • Posted by Laser Levels Online - Support on Wednesday 15th of November 2017

    Hi Paul,

    Unfortunately despite our best efforts, I am unable to ascertain from any of the Stanley literature as to the exact charge duration on the X3R.

    Although working on most laser level kits we advise around 6-8 hours.

    We do however know that it operates on an integral (sealed for life) high capacity Li-Ion battery pack offering 5000 charging cycles and the continuous use battery life is approx. 24hrs.

    Best regards
