1.5 Hazards of Use

CAUTION Watch out for erroneous measurement results if the product has been dropped or has

been misused, modified, stored for long periods or transported.

Precautions:

Periodically carry out test measurements and perform the field adjustments indicated

in the user manual, particularly after the product has been subjected to abnormal use

as well as before and after important measurements.

DANGER Because of the risk of electrocution, it is dangerous to use poles, levelling staffs and

extensions in the vicinity of electrical installations such as power cables or electrical

railways.

Precautions:

Keep at a safe distance from electrical installations. If it is essential to work in this

environment, first contact the safety authorities responsible for the electrical instal-

lations and follow their instructions.

NOTICE Strong magnetic fields in the immediate vicinity (e.g. transformers, melting

furnaces...) may influence the compensator and lead to measuring errors.

Precautions:

When working near strong magnetic fields, check results for plausibility.

CAUTION Be careful when pointing the product towards the sun, because the telescope func-

tions as a magnifying glass and can injure your eyes and/or cause damage inside the

product.

Precautions:

Do not point the product directly at the sun.

WARNING During dynamic applications, for example stakeout procedures there is a danger of

accidents occurring if the user does not pay attention to the environmental conditions

around, for example obstacles, excavations or traffic.

Precautions:

The person responsible for the product must make all users fully aware of the existing

dangers.

WARNING Inadequate securing of the working site can lead to dangerous situations, for example

in traffic, on building sites and at industrial installations.

Precautions:

Always ensure that the working site is adequately secured. Adhere to the regulations

governing safety, accident prevention and road traffic.

CAUTION If the accessories used with the product are not properly secured and the product is

subjected to mechanical shock, for example blows or falling, the product may be

damaged or people can sustain injury.

Precautions:

When setting-up the product, make sure that the accessories are correctly adapted,

fitted, secured, and locked in position.

Avoid subjecting the product to mechanical stress.

NA320/24/32, Safety Directions 6

en

WARNING If the product is used with accessories, for example masts, staffs, poles, you may

increase the risk of being struck by lightning.

Precautions:

Do not use the product in a thunderstorm.

WARNING If the product is improperly disposed of, the following can happen:

• If polymer parts are burnt, poisonous gases are produced which may impair health.

• If batteries are damaged or are heated strongly, they can explode and cause

poisoning, burning, corrosion or environmental contamination.

• By disposing of the product irresponsibly you may enable unauthorised persons to

use it in contravention of the regulations, exposing themselves and third parties to

the risk of severe injury and rendering the environment liable to contamination.

Precautions:

Product-specific treatment and waste management information can be downloaded

from the Leica Geosystems home page at http://www.leica-

geosystems.com/treatment or received from your Leica Geosystems distributor.

WARNING Only Leica Geosystems authorised service workshops are entitled to repair these prod-

ucts.

The product must not be disposed with household waste.

Dispose of the product appropriately in accordance with the national

regulations in force in your country.

3.2 Check & Adjust the line of sight

Checking the line of

sight

Adjusting the line of

sight

Step Description

With the circular bubble centred and

adjusted, the line of sight should be

horizontal.

1. Choose a distance of appr. 30 m within

a gentle terrain.

2. Set up a staff at both final points (A,

B).

3. Set up the instrument at point I1

(halfway between A and B, just pass it

down) and centre the bubble.

4. Read both staffs.

Reading on A = 1.832 m

Reading on B = 1.616 m

ΔH = A - B = 0.216 m

5. Set up the level about 1 m from staff A.

6. Read staff A (eg.: 1.604 m).

7. Find nominal reading B; eg.:

Reading A - ΔH = 1.604 m - 0.216 m =

1.388 m.

8. Read staff B, compare nominal-/actual-

reading.

more than 3 mm the line of sight must be adjusted.

1. Turn the adjusting screw until the middle hair gives

the required reading (eg. 1.388 m).

2. Check line of sight again.

Before starting field work or after long periods of

storage/ transport of your equipment check the field

adjustment parameters specified in this User

Manual.

4 Care and Transport

4.1 Transport

Transport in the

field

When transporting the equipment in the field, always make sure that you

• either carry the product in its original transport container,

• or carry the tripod with its legs splayed across your shoulder, keeping the attached

product upright.

Transport in a road

vehicle

Never carry the product loose in a road vehicle, as it can be affected by shock and

vibration. Always carry the product in its transport container, original packaging or

equivalent and secure it.

Shipping When transporting the product by rail, air or sea, always use the complete original

Leica Geosystems packaging, transport container and cardboard box, or its equivalent,

to protect against shock and vibration.

Field adjustment Periodically carry out test measurements and perform the field adjustments indicated

in the User Manual, particularly after the product has been dropped, stored for long

periods or transported.

4.2 Storage

Product Respect the temperature limits when storing the equipment, particularly in summer if

the equipment is inside a vehicle. Refer to "5 Technical Data" for information about

temperature limits.

Field adjustment After long periods of storage inspect the field adjustment parameters given in this

user manual before using the product.

4.3 Cleaning and Drying

Product and acces-

sories

• Blow dust off lenses.

• Never touch the glass with your fingers.

• Use only a clean, soft, lint-free cloth for cleaning. If necessary, moisten the cloth

with water or pure alcohol. Do not use other liquids; these can attack the polymer

components.

Damp products Dry the product, the transport container, the foam inserts and the accessories at a

temperature not greater than +40°C/+104°F and clean them. Do not repack until

everything is dry. Always close the transport container when using in the field.
