Hilti Measuring Systems Service; Checking Accuracy - Hilti PR 300-HV2S Manual De Instrucciones

NOTE
For best results, batteries should be stored fully charged
in a cool, dry place. Storing the battery in places subject
to high ambient temperatures (e.g. at a window) has an
adverse effect on battery life and increases the rate of
self-discharge.
NOTE
en
Batteries lose capacity due to aging and overstressing.
They can then no longer be fully charged. You may
continue to work with a battery that shows signs of
aging, but the battery should be replaced in good time.
1. Avoid ingress of moisture.
2. Charge the battery fully before using it for the first
time.
3. Charge the battery as soon as performance drops
noticeably.
NOTE Recharging in good time will increase the
service life of the battery.
NOTE If use of the battery continues, further dis-
charge will be stopped automatically before the
battery cells suffer damage, i.e. the tool switches
itself off.
4. Charge the batteries using only the Hilti chargers
approved for use with Li-ion batteries.
7.3 Storage
1. Remove the tool from its case if it has become wet.
Dry and clean the tool, its transport container and
accessories (while observing the permissible tem-
perature range). Repack the equipment only once it
is completely dry.
2. Check the accuracy of the equipment before it is
used after a long period of storage or transportation.
3. Remove rechargeable and non-rechargeable batter-
ies from the tool or the laser receiver before storing
the units for long periods. The tool or laser re-
ceiver may suffer damage caused by leakage from
rechargeable or non-rechargeable batteries.
7.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the batteries before shipping the tool.

7.5 Hilti Measuring Systems Service

Hilti Measuring Systems Service checks the tool and, if
deviations from the specified accuracy are found, recal-
ibrates the tool and checks it again to ensure conformity
with specifications. The service certificate provides writ-
ten confirmation of conformity with specifications at the
time of the test.
The following is recommended:
1. The tool should be checked at suitable intervals,
depending on the frequency of normal use.
2. The tool should be checked at least once a year by
a Hilti Measuring Systems Service Center.
44
3. The tool should be checked by a Hilti Measuring
Systems Service Center if it has been abused in any
way.
4. The tool should be checked by a Hilti Measuring
Systems Service Center before being used for par-
ticularly important work.
Having the tool checked by a Hilti Measuring Sys-
tems Service Center does not relieve the user of
his/her obligation to check the tool before and dur-
ing use.

7.6 Checking accuracy

NOTE
In order to ensure compliance with the technical spe-
cifications, the tool should be checked regularly (at least
before each major / relevant job).
NOTE
After falling and suffering an impact it can be assumed
that the tool will continue to operate faultlessly, with
the accuracy it achieved prior to the impact, when the
following conditions are met:
The height of the fall did not exceed the height given in
the technical data.
The tool suffered no obvious mechanical damage from
the impact (e.g. breakage of the pentaprism).
The tool projects a rotating laser beam when in operation.
The tool operated faultlessly before the impact.
7.6.1 Checking the main and transverse horizontal
axes 18
1. Set up the tripod approx. 20 m from a wall and level
the tripod head with a spirit level.
2. Mount the tool on the tripod and use the visual
sighting method (front and rear sights) to aim the
tool at the wall.
3. Use the receiver to catch the laser beam and mark
a point (point 1) on the wall.
4. Pivot the tool clockwise through 90° about its own
axis. In doing so, ensure that the height of the tool
does not change.
5. Use the laser receiver to catch the laser beam and
mark a second point (point 2) on the wall.
6. Repeat steps 4 and 5 twice and mark points 3 and
4 on the wall with the aid of the laser receiver.
When this procedure is carried out carefully, the
vertical distance between the two marked points 1
and 3 (main axis) or, respectively, points 2 and 4
(transverse axis) should be less than 2 mm (at 20 m).
If the deviation is greater than this, the tool should
be returned to a Hilti Service Center for calibration.
7.6.2 Checking the vertical axis 19 20
1. Place the tool in the vertical position on a flat floor
approx. 10 m from a wall.
2. Adjust the position of the tool so that the grips are
parallel to the wall.
3. Switch the tool on and mark the reference point (R)
on the floor.
