Laser 1 Power button (π) – turns the laser on/off. 2 Status LED – shows the status of various conditions including an internal, electronic, or a mechanical error (solid red), low-battery (flashing yellow), manual mode (flashing red), HI alert (fast flashing red), and out-oflevel (flashing green). 3 Manual button (µ) – changes the laser from automatic self-leveling to manual mode. 4 1 Axis Up (υ) and Down (δ) buttons – changes the grade for the 1 axis. 2.
9 10 11 12 13 14 15 Figure 2.1 Laser transmitter – front and back 9 Antenna (for radio remote-control lasers only) – sends and receives signals to and from the remote control. 10 Sunshade – protects the lighthouse from the environment. 11 Lighthouse – is the 360° exit window for the laser beam. The lighthouse is sealed and protects the internal components from the environment. 12 Rotor – contains the rotating laser beam. 13 Handle – allows you to carry the laser easily.
17 17 16 18 18 Figure 2.2 Laser transmitter – base and top 16 5/8-11 Tripod Mount – allows the laser to be connected to a standard 5/8-11 tripod or column mount. 17 Sighting Guides – are used to visually align the laser with a directional hub or grade stake. 18 Axis-Alignment Marks – correspond with both laser axes and are used to align the laser in the correct grade direction.
Two-Way Radio Remote Control (Radio equipped lasers only) 1 Power/Standby button (π) – turns the remote control on/off and activates/deactivates standby mode. 2 Manual button (µ) – changes the laser from automatic self-leveling to manual mode. 3 Mode button (Μ) – allows you to choose the laser’s operational mode, which includes grade change, automatic axis alignment, grade matching, PlaneLok, grade reverse, and beam rotation speed.
10 Mounting clip – allows the remote control to be connected to a grade-rod holster, belt, or a screw on a wall. 11 Battery Housing – holds two AA alkaline batteries.
Accessories 2.2 Connector cable 1 2 3 Mounting guides – fit into the mounting channels on the receiver or the radio remote control. Contacts – transfer grade-display signals between the hand-held receiver and radio remote control. 1 2 3 Clamp – connects to the receiver so signals can be transferred between the receiver and the radio remote control. 4 4 m (12-ft) cable – transfers signals between the radio remote control and a hand-held receiver.
Remote holster 1 2 Mounting slot – provides an opening for the radio remote control clip to be slipped into. 1 Mounting strap – allows the radio remote control to be connected to the grade rod for automatic alignment functions. The holes in the strap accommodate grade rods of varying sizes. 2 Battery recharger 1 2 4-socket plug with retaining collar – connects to the 4-pin receptacle on the laser. 1 Grounded receptacle – connects to the supplied grounded electrical power cord.
External power cable 1 Alligator clips (+ and –) – connect to the positive (+) and negative (–) terminals on a 12-V DC battery. 2 4-socket plug – connects to the 4-pin receptacle on the laser. 1 2 M100 3½-8 Adapter The 3½-8 adapter allows you to connect the laser which has a 5/8-11 threaded mount to a tripod or other mounting device that has a 3½-8 threaded mount. M102 Quick-disconnect adapter The quick-disconnect adapter allows you to quickly disconnect the laser from the tripod.
How to Use the Laser System Powering the laser Batteries Depending on the laser system configuration that you purchase, the laser is shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-hydride (Ni-MH) batteries. Temperature affects battery-charging time. For the best results, charge the batteries when the ambient temperature is in the range from 10 °C to 40 °C (50 °F to 104 °F). Charging at a higher temperature may damage the batteries.
1. Remove the four screws from the battery housing. Remove the battery housing compartment. 2. Install/remove the batteries. Note – when installing the batteries, be sure to note the positive (+) and negative (–) diagram inside of the housing. Note – The laser has reverse voltage polarity protection. If the batteries are put in wrong, no damage occurs to the laser but it does not work. Allow one minute for the laser to recover after the batteries have been installed correctly. 3.
Connecting the laser to a tripod All lasers have a 5/8-11 tripod mount on the bottom of the laser. Depending on the laser system you purchase, additional mounting adapters may be shipped with your laser. The steep-grade laser system includes a steep-grade adapter. The laser can also be connected to a standard tripod, column clamp, or other mounting device. If you’re using the laser without a tripod, however, make sure you set the laser on a stable surface. 1.
Turning on/off the laser 1. Press the power (λ) button to turn on the laser. Note – The laser always powers up in the automatic self-leveling mode. If the laser is out of its self-leveling range and remains out of it for more than 10 minutes, the laser shuts down completely.
Selecting the rotation speed The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The rotation speed can be changed at any time to meet your job-site conditions. Use 600 rpm for hand-held receivers and most machine-control systems. The rotation speed, which can be changed using the radio remote control, appears in the LCD. For more information about using the radio remote control, see the operator’s manual.
Quick-change method Note – The grade value can be quickly set to 0.000% by simultaneously pressing and releasing the up (υ) and down (δ) buttons for the axis you want to change. 1. Simultaneously press and hold the up and down buttons for the axis you want to change to set the grade value to 0.000%. Note – The grade value for the 2 axis increases in 1.00% increments. The grade value for the 1 axis increases in 5.00% increments. 2.
Activating/deactivating manual mode Manual mode bypasses the laser’s automatic self-leveling mode so you can use the laser in vertical mode. Manual mode also allows you to tilt the laser beyond its built-in sloping capability so you can perform steep-sloping horizontal applications. Manual mode can also be activated/deactivated using the radio remote control. The words “Manual Mode” appear in the LCD when manual mode is activated.
Aligning the axis manually The manual axis alignment buttons (Λ Ρ)rotate the grade axis electronically (simulates turning the laser on its tripod, with fine adjustment capability up to a maximum of ±40 degrees). 1. Set up the laser over a reference point. Make sure the laser is positioned so that the 1 and 2 axes are pointing in the right direction. 2. Using the sighting guides as a guide, rotate the laser on its tripod to align the laser to the direction hub. 3.
Radio remote control The radio remote control is a hand-held device that allows you to send operational commands to the laser from a remote location. These operational commands include changing grade values, rotation speed, and operating modes.
Turning on/off the radio remote control 1. Press the power button (π) to turn on the radio remote control. Note – When the radio remote control is initially turned on, the axes symbols and last-entered grade for each axis appear in the LCD. 2. To turn off the radio remote control, press and hold the power button for 3 seconds.
