Frequently Asked Questions - 1900 AA SKIL

How to replace the batteries of the Skil 1900 AA laser level?

Open the battery compartment cover (A) by sliding it. Insert 2 AAA (LR03) alkaline batteries observing the indicated polarities. Close the cover. Always use batteries of the same brand and capacity, and replace them all at the same time.

How to turn the device on and off?

Press the main button (B) to turn on the tool. The laser beam activates automatically. To turn off, hold down the main button. If the laser is disabled, the tool automatically shuts off after 5 minutes of inactivity.

What is the accuracy of the Skil 1900 AA laser level?

The accuracy is ±0.1° at 0° and 90°, and ±0.2° at other angles. This accuracy is guaranteed under normal operating conditions.

Can I use the device outdoors?

No, the device is designed for indoor use only. The operating distance (4.5 m) may be reduced outdoors due to ambient light. Also avoid moisture and extreme temperatures.

How to project a laser line on the floor?

Attach the wall mount base (H) to the protractor (M) as shown in the manual. Position the protractor in a corner or angle, then attach the tool to the base. Turn on the tool and rotate it to the desired angle. The display will show '---' when projecting onto the floor.

What does the '---' display on the screen mean?

The '---' display appears when the tool is too tilted forward or backward and cannot take a measurement. This can occur when projecting onto the floor or if the tool's angle exceeds the measurement limits. Readjust the tool's position.

How to use the digital level?

Place the tool with the angular measurement base (F) on the surface to be measured. The screen displays the angle between the surface and absolute horizontal. To level, adjust the surface until 0° or 90° is achieved. Fine adjustment arrows appear within ±10° of the target.

How to clean and maintain my laser level?

Clean the device with a soft, damp cloth. Do not use detergents or solvents. Protect it from moisture, direct sunlight, and extreme temperatures. Regularly clean the area around the laser output to remove dust.

What to do in case of malfunction?

If the device is defective, do not open it. Entrust the repair to an authorized SKIL service center. Return the tool unopened with proof of purchase to the dealer or the nearest SKIL center (addresses at www.skil.com). Damage caused by overload or misuse is not covered by warranty.

Can I use rechargeable batteries?

No, the device is designed to work with AAA (LR03) alkaline batteries. Do not use rechargeable batteries as they may not provide sufficient voltage or damage the device.

SAFETY

• All instructions must be read and observed in order to work safely with the measuring tool ②
• Never make warning signs on the measuring tool unrecognisable
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired
• The use of other operating or adjusting equipment or the application of other processing methods than those mentioned here can lead to dangerous radiation exposure
• Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself, not even from a distance (you could blind somebody, cause accidents or damage your eyes)④
• If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head away from the beam
• Do not make any modifications to the laser equipment
• Have the measuring tool repaired only through qualified specialists using original spare parts (this ensures that the safety of the measuring tool is maintained)
• Do not allow children to use the laser measuring tool without supervision (they could

unintentionally blind other persons or themselves)

• Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dusts (sparks can be created in the measuring tool which may ignite the dust or fumes)
• Keep the measuring tool away from cardiac pacemakers (the magnet inside the measuring tool generates a field that can impair the function of cardiac pacemakers)
• Keep the measuring tool away from magnetic data media and magnetically-sensitive equipment (the effect of the magnet can lead to irreversible data loss)

EXPLANATION OF SYMBOLS ON TOOL

② Read the instruction manual before use
③ Do not dispose of electric tools and batteries together with household waste material

-press and hold main button B to turn off the tool

- Projecting on walls

-mark the point where the laser line should be projected
-place the wall mount base H with the marked point centered in the viewing window K
-mounting options:

1) use adhesive putty (included) on surfaces L ⑦ a or use tape (not included) to mount base on dry and clean surfaces ⑦ b

-the adhesive putty may used repeatedly
-to keep good adhesion, wash the putty frequently and store it in the adhesive putty storage S
-remove the wall-mount base from the wall slowly after using, any residue of the adhesive putty on the wall can be cleaned by rolling the adhesive putty over the residue

2) use pins (not included) through pin holes N to mount base on soft materials (plasterboard, soft wood) ⑦c

! be aware of sharp pins

-alternatively, use magnetic edge E to attach the tool to a ferrous surface
-the display shows the angle between the surface and absolute level

! if the display shows --- the tool is inclined to forward or backward too much and the measurement cannot be made

-to level or plumb the working surface, move the surface until the display shows 0° or 90°

-if the deviation is within ±10^ of 0^ and 90^ , fine-tuning arrows are shown which vary in direction and height relative to the target ^⑫

APPLICATION ADVICE

• Always use the centre of the laser line for marking (the width of the laser line changes with the distance)
- Laser viewing glasses ① (not standard included)

-laser viewing glasses R ① filter out the ambient light
-this makes the light of the laser appear brighter for the eyes
-do not use the laser viewing glasses as safety goggles (the laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation)
-do not use the laser viewing glasses as sun glasses or in traffic (the laser viewing glasses do not afford complete UV protection and reduce colour perception)

MAINTENANCE / SERVICE

• This tool is not intended for professional use
- Protect the measuring tool against moisture and direct sun light
- Do not subject the measuring tool to extreme temperatures or variations in temperature (the accuracy of the measuring tool can be impaired)

-as an example, do not leave it in vehicles for long time
-allow the measuring tool to adjust to the ambient temperature before putting it into operation

- Avoid heavy impact to or falling down of the measuring tool

-damage to the measuring tool can impair its accuracy

• Keep the measuring tool clean at all times
• Do not immerse the measuring tool in water or other fluids
• Wipe off debris using a moist and soft cloth
• Do not use any cleaning agents or solvents
• Regularly clean the surfaces at the exit opening of the laser in particular, and pay attention to any fluff of fibres
• If the tool should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an after-sales service centre for SKIL power tools
