Transport; Troubleshooting - Hilti PR 3-HVSG Mode D'emploi

7.4 Transport

Use the Hilti packaging or packaging of equivalent quality
for transporting or shipping your equipment.
Observe national and international transport regulations
when shipping batteries (transportation by road, rail, sea
or air).
7.5 Hilti Measuring Systems Service
en
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.
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
In order to ensure compliance with the technical spe-
cifications, the tool should be checked regularly (at least
before each major / relevant job).
After falling and suffering an impact it can be presumed
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.

Electrical fault.
axes 8
Set up the tripod approx. 20 m (66 ft) from a wall
and adjust the tripod head horizontally with a spirit
level.
Mount the tool on the tripod and use the aiming
notch to aim the tool at the wall.
Use the receiver to catch the laser beam and mark
a point (point 1) on the wall.
Pivot the tool clockwise through 90° about its own
axis. In doing so, ensure that the height of the tool
does not change.
Use the laser receiver to catch the laser beam and
mark a second point (point 2) on the wall.
Repeat steps 4 and 5 twice and mark points 3 and
4 on the wall with the aid of the laser receiver.
If the procedure has been carried out accurately, the
vertical distance between the two marked points 1
and 3 (main axis) or, points 2 and 4 (transverse axis),
should each be less than 3 mm (at 20 m) (0.12"
at 66 ft). If the deviation is greater than this, the
tool should be returned to a Hilti Service Center for
calibration.
Place the tool in the vertical position on a floor,
which is as flat as possible, approx. 20 m (66 ft)
from a wall.
Adjust the position of the tool so that the grips are
parallel to the wall.
Switch the tool on and mark the reference point (R)
on the floor.
With the aid of the receiver, mark point (A) low on
the wall. Select medium speed.
With the aid of the receiver, mark point (B) at a
height of approx. 10 m (33 ft).
Pivot the tool through 180° and realign it with the
reference point (R) on the floor and with point (A) at
the base of the wall.
With the aid of the receiver, mark point (C) at a
height of approx. 10 m (33 ft).
NOTE If the procedure has been carried out ac-
curately, the horizontal distance between the two
points (B) and (C) marked at a height of ten meters
should be less than 2 mm (at 10 m) (0.08" at 33 ft).
If the deviation is greater: Please return the tool to a
Hilti Service Center for calibration.
Remedy
The battery must be heard to engage
with a click or, respectively, needs to
be charged.
Switch the tool off immediately, re-
move the battery and contact Hilti
Service.
