Laser Detectors (Laser Receivers): Another integral part of using a rotary laser is the laser detector or laser receiver. Laser detectors typically mount to level rods and work to detect the laser beam when you’re working outside. The detector is usually required when working outside as the laser line is difficult to see in direct sunlight.

General Safety Warnings
WARNING Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
1.Work area safety
a.Keep work area clean and well lit.
Cen Tech Manuals Laser Leveling
Cluttered or dark areas invite accidents.
b.Do not operate the Scale in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Line operated and battery operated equipment create sparks which may ignite dust or fumes.
c.Keep children and bystanders away while operating the Scale.
Distractions can cause you to lose control.
2.Electrical safety
a.The Power Plug (17) must match the outlet. Never modify the Plug in any way. Do not use any additional adapter plugs with the Scale.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b.Avoid body contact with grounded surfaces such as pipes, radiators,
SKU 98982 | For technical questions, please call 1-800-444-3353. | Page 2 |
ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
c.Do not expose the Scale to rain or wet conditions. Water entering the
Scale will increase the risk of electric shock.
d.Do not abuse the Power Cord
(17). Never use the Cord for carrying, pulling or unplugging the Cord. Keep the Cord away from heat, oil, sharp edges or moving parts. Damaged or entangled Cords increase the risk of electric shock.
e.When operating the Scale outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f.If operating the Scale in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
3.Personal safety
a.Stay alert, watch what you are doing and use common sense when operating the Scale. Do not use the Scale while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the Scale may result in serious personal injury.
b.Use safety equipment. Always wear eye protection. Safety equipment such as ANSI-approved safety impact goggles will reduce personal injuries.
c.Prevent unintentional starting. Ensure the Power Switch (15) is in the off-position before connect-
ing to power source and/or battery pack, picking up or carrying the tool. Carrying battery operated equipment with your finger on the
Power Switch or energizing equipment that have the Power Switch on invites accidents.
d.Do not overreach. Keep proper footing and balance at all times.
This enables better control of the
Scale in unexpected situations.
4.Scale use and care
a.Do not force the Scale. Use the correct Scale for your application.
The correct Scale will do the job better and safer at the rate for which it was designed.
b.Do not use the Scale if the Power
Switch (15) does not turn it on and off. Any equipment that cannot be controlled with the Power Switch is dangerous and must be repaired.
c.Unplug the Power Cord (17) before making any adjustments, changing accessories, or storing the Scale.
Such preventive safety measures reduce the risk of starting the equipment accidentally.
d.Store idle equipment out of the reach of children and do not allow persons unfamiliar with the Scale or these instructions to oper-
ate the equipment. Line powered and battery powered equipment are dangerous in the hands of untrained users.
e.Maintain the Scale. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the Scale’s operation. If damaged, have the Scale repaired before
SKU 98982 | For technical questions, please call 1-800-444-3353. | Page 3 |
use. Many accidents are caused by poorly maintained equipment.
f.Use the Scale in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the Scale for operations different from those intended could result in a hazardous situation.
5.Battery tool use and care
a.Use this Scale only with specifically designated Batteries. Use of any other Battery may create a risk of injury and fire.
b.Under abusive conditions, liquid may be ejected from the Battery (16). Avoid contact. If contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek medical help. Liquid ejected from the Battery may cause irritation or burns.
6.Service
a.Have your Scale serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the equipment is maintained.

3.Do not exceed the Scale’s maximum weight capacity of 330 pounds.
4.Use in a dry location only. Risk of electric shock.
5.Use on a level, solid surface capable of supporting the weight of the Scale and its load.
6.Do not lean load against display.
7.Level the Scale before use.
8.Wear ANSI-approved safety goggles during assembly and Battery (18) replacement.
9.This Scale is not legal for trade or postage.
10.Read this manual before set up and use of the Scale.
11.Do not sit or stand on the Scale.
12.Avoid unintentional starting. Prepare to begin work before turning on the Scale.
13.Do not leave the Scale unattended when it’s Power Cord (17) is plugged into an electrical outlet. Turn off the equipment, and unplug the Power Cord from its electrical outlet before leaving.
14.This product is not a toy. Keep it out of reach of children.
