WARNING

:

To reduce the risk of injury, the user must read

and understand the operator’s manual before

using this product.

WARNING!

READ AND UNDERSTAND ALL INSTRUC-

TIONS.

Failure to follow all instructions listed

below, may result in electric shock, fire and/or

serious personal injury.

CAUTION:

Use of controls or adjustments or performance of

procedures other than those specified herein may

result in hazardous radiation exposure.

CAUTION:

The use of an optical instrument with this product

will increase eye hazard.

The laser guide radiation used in this laser level is
Class IIIa with < 5mW and 630-660 nm wavelengths.
These lasers do not normally present an optical
hazard although staring at the beam may cause
flash blindness.



Avoid

direct eye exposure when using the laser

and do not project the laser beam directly into
the eyes of others.

Serious eye injury could

result.



Do not remove or deface any product labels.

Removing product labels increases the risk of
exposure to laser radiation.



Do not place the laser level in a position that
may cause anyone to stare into the laser beam
intentionally or unintentionally.

Serious eye

injury could result.



Do not operate the laser level around children
or allow children to operate the tool.

Serious

eye injury could result.



Always turn the laser level off when not in use.

Leaving the tool on increases the risk of someone
inadvertently staring into the laser beam.



Do not operate the laser level in combustible
areas such as in the presence of flammable
liquids, gasses, or dust.



Always ensure the laser beam is aimed at a
surface without reflective properties.

Shiny

reflective materials are not suitable for laser use.



Handle the laser level with care.

Treat it as you

would any other optical device such as a camera
or binoculars.



Avoid exposing the laser level to shock,
continuous vibration or extreme hot or cold
temperatures.

Damage to the tool and/or serious

injury to the user could result.



Save these instructions.

Refer to them fre-

quently and use them to instruct others who may
use this laser level. If you loan someone this laser
level, loan them these instructions also.

ASSEMBLY

OPERATION

UNPACKING

If any parts are damaged or missing, please call 1-800-525-2579 for assistance.

OPERATION

TURNING ON/OFF

See Figure 1.

The on/off switch is located on the front of the laser
level. Depress the switch to turn the laser

ON

; Depress

the switch again to turn the laser

OFF

. Always wait for

at least 5 seconds between stopping and restarting
the laser level.

INSTALLING/REPLACING BATTERIES

See Figure 2.

Two AAA batteries are included.



Depress the ridged area on the back of the laser

level and remove the cover.



Install batteries according to polarity indicators

(+ or –) inside the battery compartment.



Position the battery cover over the compartment.

Slide and push the cover until it clicks into place.

WARNING

:

When turning on the laser level, ALWAYS protect

the eyes of yourself and those around you. NEVER

point the laser beam at anyone’s face, including

your own.

USING THE LASER LEVEL

See Figures 3 - 5.



Always turn the laser beam off when mounting

the laser level.



Two bubble levels allow for either horizontal or

vertical leveling.



The laser level and cradle are preinstalled onto

the protractor base.



To remove the protractor base for other applica-

tions, loosen the screw and knob that hold it in
place.



The cradle provides hands-free use, but the laser

level may be used alone.



The protractor base with push pins can be used

on either a smooth or non-smooth surface. The

magnet can be used with or without the protractor

base, only on a smooth metal surface without the

push pins.

USING THE PROTRACTOR BASE

For projecting the laser beam at an angle, from 0°

to 90°.



Remove the push pins from the storage area.



Place the protractor base flat against the desired

surface.

NOTE:

It may be helpful to place a push pin at

90° to hold the base steady while you level the
base at 0°.



Use the bubble levels to set the base horizontally

at 0°.



Push a pin into the lower hole at 0°.



Turn the laser on to project the laser beam.



Pivot the laser level to set the laser beam to the

desired angle.

MOUNTING WITH THE MAGNET

The magnet feature may be used with or without the
protractor base attached.



Attach the magnet to a clean metal surface.



Use the bubble levels to level the unit.



Turn the laser on to project the laser beam.

MOUNTING WITH THE SUCTION CUPS

For mounting to smooth surfaces.



Remove the protractor base.



Place the unit onto a smooth, nontextured surface

but do not press the suction cups into place.



Use the bubble levels to level the unit.



Hold the laser level in place and press the suction

cups onto a nontextured surface until they are
securely in place.



Turn the laser on to project the laser beam.

NOTICE:

To release suction cups from the surface, lift the
tabs on the sides of the suction cups. Pulling on
the unit without first loosening the suction cups
could damage the multisurface cradle.

MOUNTING WITH THE PUSH PINS

For securing the laser level on non-smooth surfaces.



Remove the protractor base.



Remove the push pins from the storage area.



Place the laser level onto the desired surface and

use the bubble levels to level the unit.



Insert a push pin into each hole on the sides of

the cradle and push the pins into the mounting
surface.



Turn the laser on to project the laser beam.
