Lasermart LM30 wont spin and all lights blinking


My LM30 worked OK for a while, then the zig-zag chalk line feature stopped working, and finally it would not spin for more than a second for either rotate setting, and got the flashing lights thing. Of course tried replacing batteries to no avail. So the meticulous experimenter in me started on a mission to find out why it stopped working.

If my findings are the only reason this unit gives this error, the company should be ashamed of itself charging so much for such a simple repair.

Check these two things if you get the no spin/flashing lights problem.

Test one: Gently holding the rotating head, lift up a bit. If there is a little up/down movement when you lift on it, go to test two.
Test two: Holding the unit upside down, try running through the functions. If all functions work, the repair is easy and inexpensive/free.

The problem is there needs to be no axial shaft slop for the unit to work, and that slop is removed with a thin wave washer under the spinning head. That washer get's weak over time, and I think there is a sensor on the board that makes sure the drive pulley doesn't drop too far down, which triggers the shutdown.

Tools needed:
Phillips screwdriver
Small phillips screwdriver
1.5mm allen key
Retaining ring pliers

The fix:
1) Remove batteries and the screws from the top of the spinning head, and remove the cover.
2) Remove three screws from the bottom of the LM30 holding the yellow case on.
3) Carefully lift off the case. The control board has a slide pin connection to join it to the rest of the internals. It has a slight resistance to being removed, but if you feel a higher resistance, the control board is probably snagging on the drive motor inside. Squeezing the case sides gives you a little more clearance. Take your time getting it off.
4) Remove a 1.5mm allen head jam screw from the prism head, and carefully slide the prism off the shaft (gently prying up with a screwdriver)
5) With retaining ring pliers, remove the retaining ring.
6) Remove the wave washer. You can find a replacement or simply bend the existing one to make it a bit "wavier". Don't go crazy, just bend it slightly more than it is.
7) Support the shaft with a screwdriver inserted under the drive pulley
8) Replace the wave washer on the shaft.
9) Replace the retaining ring
10) Temporarily remove screwdriver to check that there is no up/down slop in shaft. If there is, you need to bend the washer a little more.
11) Reinsert screwdriver for support.
12) Carefully replace prism and reinstall the allen screw
13) Remove screwdriver providing shaft support
14) Carefully replace yellow cover, assuring slide connectors line up on the control board, and replace three screws
15) Replace prism cap and screws.
16) Replace batteries and test functions.

I need a manual. Power will not come on. Changed batteries. No power. Also, where does the red attachment that tells you to go up or down hook on? I have power to the unit which hooks to the pole.


Hi Richard.
The manual is available from this webpage.

http://www.cstberger.co.uk/uk/en/

Type lm30 into the text box which says "trade name/tool number" and click "start search"
Click on the thumbnail then to download the pdf.
Check for corrosion on the battery terminals and those in the laser.
From what I can see in the manual, there should be a clamp for the laser receiver that lets you clamp it to a staff.
The target plate (part 24 in the manual) has a reflective coating and there should be a magnetic holder for it.

Hi there.

Ok in WIDE beam mode the cone extends out 45 degrees from the transducer. This covers a fair area, but is best used only in shallow waters as the beam may not have enough power to penetrate deeper waters effectively. 30ft should be fine for WIDE mode however. Using a bit of trigonometry, the beam would extend to a diameter of 60 feet from the center point of the transducer on the sea/river floor.

The beam is a direct beam... It is not a rotational beam from the transducer... i.e. it does not rotate like a radar beam but shoots downward in the cone arc constantly. Imagine a torch being turned on and off very rapidly... The light shoots straight out from the torch in its own cone shape. This is essentially what the transducer does when it shoots out a signal every millisecond or so.

The image you see on the screen is the result of the hole cone of signals, however, the strongest sonar returns occur near the center of the beam. Weaker returns are shown which are located towards the outer edges of the sonar cone where the signal power is less. So if a fish passes right on the edge of the beam, it will only show up as maybe 1 pixel on the sounder screen as it is a weak return on the edge of the sonar cone, whereas if that fish passes under the center of the beam, it will show a larger, more continuous or arched shaped return as the fish moves from the outside of the beam, through the center of the beam, and out to the other edge of the beam under the boat.

Regarding the flasher... I would advise not to use this. It does work by showing a continuous top and bottom reading which displays as constant flashes around the circle readout. Anything it picks up in the beam will show as flashes in between the top and bottom readings. Using the display is far better and with practice allows you to better identify fish and bottom structure readings. Flashers were earlier forms of sonar readouts. Some older folk still like them but I believe the normal display is better for finding and identifying fish and can show structure shape as well (the flasher mode really cannot).

Hope that helps!
