Genaral Safety Instructions

WARNING

Read all safety warnings and instructions.
Before using the appliance, read these
safety instructions, the appliance’s oper-

ator’s manual (found on the enclosed CD)
and all labels on the appliance.

• Do not allow persons unfamiliar with the
appliance, these safety instructions, and
the appliance’s operator’s manual to
operate the appliance.

This appliance can be dangerous in the
hands of untrained users.

• Do not overreach. Keep proper footing
and balance at all times.

This enables better control of the appli­ance in unexpected situations.

• Ensure adequate safeguards at the work
site (e.g. surveying site when measuring
on roads, construction sites, etc.)

WARNING

The device produces visible laser beams,
which are emitted from the appliance.
This device is a Class 2 laser product in
accordance with IEC 60825-1:2007

• Laser light - Do not stare into beam or
view directly with optical instruments.

Do not point laser light at others. Laser
light can cause eye damage.

• Avoid dangerous environments.

Do not use in rain, snow, damp or wet loca­tions. Do not use in the presence of explo-

sive atmospheres (gaseous fumes, dust or
flammable materials).

• Maintain appliances. If damaged, have
the appliance repaired before use.

Accidents may be caused by poorly main­tained appliances.

• Use appliance only with specifically
designated accessories.

Use of any other accessories may create a
risk of injury.

• This tool is designed to be powered by
2-AAA batteries properly inserted into
the tool.

Do not attempt to use with any other
voltage or power supply.

• Do not leave batteries within the reach of
children.

• Do not mix new and used batteries.

• Do not mix brands (or types within

brands) of batteries.

• Do not mix rechargeable and non­rechargeable batteries.

• Install batteries according to polarity
(+ / –) diagrams.

• Properly dispose of used batteries
immediately.

• Do not incinerate or dismantle batteries.

• Under abusive conditions, liquid may be

ejected from the battery, 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.

• Keep hands away from all moving parts.

• Watch out for erroneous measurements

if the appliance is defective or if it has
been dropped, misused or modified.

• Carry out periodic test measurements.
Particularly after the appliance has been

subject to abnormal use, and before,
during and after important measurements.

• Do not dispose of appliance or batteries
together with household waste material!

Appliance and batteries that have reached
the end of their life must be collected sepa­rately and returned to an environmentally
compatible recycling facility.

• Have your appliance serviced by a qual­ified repair person using only identical
replacement parts.

This will ensure that the safety of the appli­ance is maintained.

• Maintain labels and nameplates.

These carry important information. If
unreadable or missing, contact a
MILWAUKEE service facility for a free
replacement.

• The device conforms to the most strin­gent requirements of the relevant elec­tromagnetic compatibility (EMC) stan­dards and regulations.

Yet, the possibility of causing interference
in other devices cannot be totally
excluded.
