GEO LASER LL-80L-81L Plumb-Up Laser

Plumb-up Laser LL-80L/-81L
Plumb-down Laser LL-82L/-83L

Congratulations on your new GEO laser
These operating instructions contain enclosed in addition to information on how to use the laser important safety information.

Please note: First read the safety instructions on the supplement page 1-3and then the operating instructions carefully before using the laser.

Description

The laser emits an automatically levelled plumb laser beam as a reference axis. This laser beam is, for example, represented as a dot on a target. If the target is connected to sliding moulding, the moulding can be controlled according to the position of the laser dot. The LL is a special laser for all types of plumbing operations. Its possible uses are virtually unlimited.

Device Settings

Automatic Levelling Cut-Out

• Automatic levelling switched on (factory defaults)
• Automatic self-levelling cutted out for both axes. On the display X-A OFF + Y-A OFF is indicated.
  When the automatic is cutted out, the laser can be positioned just as you like it. For electromotive fine/coarse adjustment of the laser beam, push the respective arrow buttons. Longer pushing changes the direction with increasing speed.

Sensitivity Setting (Wind/Vibration)

The self-levelling function corrects even the smallest deviation. Additionally, the laser beam and the laser beam symbol at the operating mode display blink when the limit values of step 1 to 3 are exceeded, i. e. by the influence of wind and/or vibration.

1. = 0.005 % no effect
2. = 0.010 % weak effect      factory defaults
3. = 0.015 % strong effect

Kick Guard (Automatic Laser Cut-Out)

Kick guard switched on. It is only active after 30 sec. Then a T appears

in front of the battery symbol at the operating mode display
This means the laser is switched off automatically as a precautionary measure in the event of a jerky movement (bump). The T then begins to blink. The laser must be switched on again and the positioning checked and corrected if necessary.

actory defaults : Kick guard switched off.

Laser Beam Flickering

• Flickering off ( factory defaults)
• Flickering on. Flickering makes the laser beam significantly easier to see in unfavourable light conditions.

Laser Power (only LL-81L/-83L)
The laser power can be regulated in 5 steps from < 1 mW to 5 mW.

• < 1 mW
• step 5, equivalent to < 5 mW (factory defaults)

Operating Mode Laser Beam

• Laser beam and laser beam symbol blink at the operating mode display when levelling (factory defaults).
• Laser beam is off when levelling.
  However the symbol blinks at the operating mode display.

Factory Defaults

• All set to factory defaults.

Service/Workshop Notice

First off all a phone no. for service/help appears.
Then authorized personnel can put in a numerical code to come to the adjustment mode.

Power Supply

7.4 V DC internal lithium-ion rechargeable battery or 12 V DC external rechargeable battery via connection cable 0117.02.

Battery Charging

• Carry out charging only with the power and charging unit, type NE-80 or a 12 V DC external rechargeable battery via connection cable 0117.02.
• Keep charger dry and only use in rooms.
• For charging take the laser out of the transport case.
• Permissible charging temperature 0°C to + 40°C, as best + 10°C to + 25°C.
• After approx. 5 hours the charging time is finished. The display goes out or the battery symbol shows a full battery.
• Low ambient temperatures reduce the running time, high temperatures reduce the battery life.
• Damaged batteries must be disposed of.

Inclination Works in x and/or y Axes

Please note: Inclination setting is only possible without automatic levelling.

• Align laser to the inclination axis.
• Switch off automatic levelling.
• Set inclination by points of reference, roughly more than ± 5 % by tilting forwards the device, finely with the arrow buttons.

Adjustment

Checking the Adjustment

Set up the laser standing upright and mark the laser beam at the required measuring distance. Turn the laser by 180° and mark again. If the adjustment is correct, the first marking does not deviate from the second.
If there is a deviation, the target axis lies in the middle between the first and second marking.

Adjustment
The laser can be adjusted in the field without having to open the device. For safety reasons, however, adjustment should only be carried out by authorized personnel. See the special adjustment instructions in this regard.

Troubleshooting

1. No laser beam – check the battery charge.
2. Low range – clean laser beam exit window.
3. Laser beam blinks slowly – move device into the levelling range by tilting forwards. If the error is not corrected within 2 ½ minutes, the device is switched off automatically.
4. Laser switched off automatically (kick guard) – see 3.3.

Maintenance

The laser requires no special maintenance. Keep the electrical connections clean. Do not clean with water spray. Clean glass parts with a soft, clean cloth. Store dry. Always transport the laser in its original case.
