With David White
your sights are set on
precision and accuracy.
Congratulations! You’ve purchased a David White builder/contractor instrument,
known throughout the world for precision and accuracy.
The purpose of this user’s guide is to acquaint you with the instrument, its
components, safety, proper care and handling.
Our levels, level-transits and transits are constructed to withstand extremely
rugged field use. Like all precision instruments, however, they should be treated
with reasonable care to prolong life and accuracy.
All instruments are adjusted when they are shipped from the factory. It is the
customer’s responsibility to check and to ensure instruments are adjusted prior
to using.
David White is not responsible for errors caused by instruments that are out of

horizontal position. Improper handling may result in instrument damage
Handle the instrument by its base when removing from the case or attaching to a tripod.
Never use force on any parts of the instrument. All moving parts will turn freely and easily
by hand.
DO NOT directly aim the telescope to the Sun to avoid injury to your eyes
Check the leveling and indication accuracy of the instrument each time before using and
after longer transport of the instrument.
Protect the instrument against moisture and direct sun light.
DO NOT subject the instrument to extreme temperatures or variations in temperature.
As an example, do not leave it in vehicles for long time. In case of large variations in
temperature, allow the instrument to adjust to the ambient temperature before putting
it into operation. In case of extreme temperatures or variations in temperature, the
accuracy of the instrument can be impaired.
This instrument contains many sensitive electronic components and is provided
with protection against dust and moisture. Once dust or moisture enters into the
instrument they will cause damage to the instrument. Therefore, after using in a humid
environment, the instrument must be dried immediately and stored in the instrument
case.
Avoid any impact to or dropping of the instrument. After severe exterior effects to the
instrument, it is recommended to carry out an accuracy check (see “Check”, page 8)
each time before continuing to work.
Place the instrument in the provided case when transporting it over larger distances
(e.g. in the car). Ensure that the instrument is correctly placed in the transport case.
When placing the instrument in the case.
When carrying instrument, always remove the instrument from the tripod when
transporting or carrying it at the jobsite. If the instrument must be carried on the tripod,
hold the instrument as vertically as possible and keep it in front of you. Never carry the
instrument horizontally over your shoulder.
When transporting instrument long distances, always place in the carrying case.
