Pro Shot laser FAQ:

PROSHOT LASERS Frequently Asked Questions

Q: The L4.7, L4.7 Magnum, and L5 are described as self levelling or automatic. How come I have to turn levelling screws?

A: These models self level via wire hung compensators. These are gravity pendulum levelling mechanisms that must be rough leveled. Once the instrument is in its self levelling range, the compensator makes sure that the beam is level. The term "automatic" derives from automatic optical levels which employ compensators for self leveling. These auto levels also have to be rough leveled. Servo motor leveling systems have a wider self levelling range and allow the user to turn the laser on without having to turn levelling screws.

Q: Which self levelling system is better, servo motor or compensated?

A: Each system has its pluses and minuses. Servo systems have the appeal of driving the laser to level without the operator turning levelling screws. However, a compensated self leveling laser can be up and running just as fast as a servo system. Servo systems are more complex electronically, draw more power, and have been more prone to drift with temperature change. Well designed servo systems and compensated systems both provide accurate and reliable results. For grade checking and concrete work, compensated systems have been the mainstay for many years. If the laser is going to be used in a situation where it is inconvenient to turn levelling screws, (up on a 14m tripod for machine control), a servo system would be preferable.

Q: Can I use a visible laser outdoors without a receiver?

A: A rotary laser will have to be used with a receiver outdoors in the sun. Safety regulations do not permit a beam powerful enough to be visible when rotating out in sunlight. If you stop the rotating beam and shine it onto a shaded target, you can use it as a reference, but this is not that convenient.

Q: What kind of working distance do your products have?

A: When paired with the R7 receiver, the L4.7 has a 380m working diameter, and the L4.7 Magnum and AS2 have a 450m working diameter. The L5 and L3 provide a 250m diameter when paired with the R5e receiver.

Q: How often should my laser be calibrated?

A: Lasers should be calibrated when they are not shooting their specified accuracy. We suggest checking calibration regularly, at least every 6 months, or immediately if the unit has been treated roughly.

Q: Can I dial a grade or slope into the laser?

A: You can with the AS2 and AS2 Magnum, you cannot with the L5, L4.7, L4.7 Magnum or ALPHA. The L3 features a vial with markings for 1, 2, 3, or 4% slope.

Q: Where can I get my laser serviced?

A: Almost any laser or survey instrument service centre can calibrate our lasers, or the user can do so if he/she so desires. Many of our 400+ dealers in the US have some service capabilities ranging form calibrating lasers up through full repairs.

Q: What kind of tripod do I need?

A: Our lasers fit tripods with a 5/8 x 11 coarse thread. Dome or flat head tripods can be used. A flat head tripod will allow the user to check calibration out in the field.

Q: Can the laser light hurt my eyes?

A: The maximum power output for any construction laser is less than 5 milliwatts. A milliwatt is one thousandth of a watt. No special precautions need be taken with an invisible beam laser. Visible beam lasers should be set so they are not flashing in anyone’s eyes because the light is very bright and can be annoying. Having the beam flash in one’s eyes occasionally will not do any damage, but will be irritating in the same fashion as a camera flash.

Q: Can your laser be used for turning angles?

A: Our visible beam L4.7 Magnum, L5 and L3 have fixed plumb spots that provide a 90 degree reference relative to the rotating beam when the laser is in its vertical mode. This is only useful indoors out of the sun.

Q: Can I use a receiver to pick up the plumb spot?

A: Electronic laser receivers are looking for a laser spot flashing across their photocells and will not respond to a stationary laser spot. That is why they can be set off by a flashing strobe or emergency beacon. Even if the receiver could pick up a stationary beam, the spot will be extremely difficult to find at any substantial distance from the laser.

Q: What happens if my laser is rained upon?

A: Pro Shot lasers are water and dust resistant. Our Oregon dealers test our lasers by dumping a bucket of water over them. Simply dry the laser off before it is stored.

Pro Shot laser calibration:

It is important to know how to check calibration of a laser level. We recommend that you check the calibration of your laser after it has been shipped, or if it has taken a drop or an impact. The following procedure will work with any rotating laser level.

Checking the calibration of the laser is the responsibility of the contractor. This is a simple procedure that takes about 10-15 minutes. The only equipment needed are a flat head tripod, the laser and detector, and a carpenter's level.

Set the tripod up so that it is approximately 30m from a fixed object such as a wall or utility pole. Take the carpenter's level, and, using the tripod legs, level the head of the tripod as carefully as possible.

Attach the laser to the tripod and level it with the screws on the laser base, (L4, L4+, and L5 only). Servo leveled lasers such as the L1-AS, L6 and ALPHA will automatically level upon being turned on. If the tripod head has been properly leveled, it will be possible to rotate the laser 360° on the tripod with minimal re-levelling.

Rotate the laser so that the front is pointed at the target. On the L1-AS this will be the sloping part of the main housing. On the L4, L4+, or L5 this will be the side with the control panel.

Turn the laser on, then go to the target with the detector. Remove the clamp. When the detector gives the on grade signal, make a mark on the target using the detector's marking notch. Label this mark +Y.

Go back and rotate the laser 180 degree so that the back side of the laser is pointed at the target. This will be the side with the battery cover. Make sure that the laser is still level. Make a level mark with the detector, just as before. Label this mark -Y. The mid point between the -Y and +Y marks is true level. If the specified accuracy of the laser is +/-3mm inch, neither the -Y or +Y marks should be more than 3mm inch from the mid point. If the specified accuracy of the laser is +/-1.5mm inch, neither the -Y or +Y marks should be more than 1.5mm from the mid point.

Rotate the laser 90 degree the third side of the instrument is pointed at the target. Make sure the laser is level. With the detector, mark level on the target. Label this mark +X. The distance between this mark and true level should be within the specified accuracy of the laser. If the laser needs calibration refer to the full calibration procedure in the operator's manual, or contact Laser Sonics www.lasersonics.com.au

Pro Shot laser battery:

Pro Shot L3 and L5 lasers run on 2 D batteries, while the L4, L4+, L1-AS, and L1-AS

The L1-AS Magnum, L4, L4+, L3, and L5 lasers are designated class II or IIIa under the 1993 IEC 825-1 laser safety standard and the revised edition of the European Norm EN60825. They conform to applicable EC directives regarding RFI and EMI. US OSHA requires that a jobsite warning placard must be posted in the work area, and laser operator must carry proof of qualification. Only qualified and trained employees are to install, adjust, and operate the laser. The laser should be set up above head level and never intentionally aimed at anyone. The laser should be turned off when not being used.

Magnum run on 4 C cells. Disposable alkaline batteries or rechargeable NiMH batteries can be used. We recommend the NiMH rechargeable batteries. They provide almost as much run time as alkaline batteries, (more than 40 hours in all our lasers), and can be charged up to 500 times under optimal conditions. They provide hundreds of dollars of savings in battery costs over the life of the laser. Furthermore, NiMH batteries are less toxic to the environment, and put less strain on our landfills than alkaline or NiCd batteries. [ Because they do not maintain voltage, heavy duty type batteries should not be used and combinations will cause breadown. ]

Safety:

The maximum allowable power output in a rotating construction laser is 5 milliwatts or less. A milliwatt is 1/1000th of a watt, a very small amount of power. The light is concentrated however, and the following precautions should be taken when using such an instrument:

Do not stare into a laser beam or view it directly with optical instruments.

Do not disassemble the laser or attempt to service it.

Do not use the laser until you have read the instruction manual and you are familiar with the operation of the instrument.

Infra-red beam lasers are designated class 1 laser products. No jobsite warning placards or operator certification cards are required. No Product warning labels are required on the laser. These meet class 1 requirements under the 1993 IEC 825-1 laser safety standard and the revised edition of the European Norm EN60825.
