Checking Accuracy; Transport And Storage; Transport And Storage Of Cordless Tools - Hilti PR 30-HVSG A12 Manual De Instrucciones

Having the product checked by Hilti Measuring Systems Service does not relieve the user of his/her
obligation to check the product before and during use.
7.3

Checking accuracy

In order to ensure compliance with the technical specifications, the tool should be checked regularly (at least
before each major / relevant measuring task).
After falling from considerable height, the tool should be checked for correct, accurate operation. When the
following conditions are fulfilled it can be assumed that the tool is operating faultlessly:
• The height of the fall did not exceed the height given in the technical data.
• The tool operated faultlessly before the impact.
• 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.
7.4 Checking the main and transverse horizontal axes
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. Fig. a: 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. Fig. b: Use the laser receiver to catch the laser beam and mark a second point (point 2) on the wall.
6. Fig. c and d: Repeat the two previous steps twice and use the laser receiver to catch the beam and mark
points 3 and 4 on the wall.
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, please return the tool to Hilti Service for calibration.
7.5 Checking the vertical axis
1. Place the device in the vertical position on a floor that is as flat as possible, approx. 1 to 10 m from a
wall.
2. Align the grips parallel with the wall.
3. Switch on the device and mark the reference point (R) on the floor.
4. With the aid of the receiver, mark point (A) at the base of the wall.
5. With the aid of the receiver, mark point (B) at a height of approx. 10 m.
6. Pivot the device through 180° and realign it with the reference point (R) on the floor and with point (A) at
the base of the wall. This can also be done using the automatic alignment function.
7. Bring the vertical laser plane into alignment automatically. → page 31
8. With the aid of the receiver, mark point (C) at a height of approx. 10 m.
▶ When this procedure is carried out carefully, the horizontal distance between the two marked points
(B) and (C) should be < 2 mm (at 10 m). If the deviation is greater than this, return the device to Hilti
Service for calibration.
