ORIGINAL OPERATING INSTRUCTIONS PR 300-HV2S rotating laser It is essential that the operating instructions are read before the tool is operated for the first time. Always keep these operating instructions together with the tool. Ensure that the operating instructions are with the tool when it is given to other persons.
1 General information 1.1 Safety notices and their meaning en DANGER Draws attention to imminent danger that will lead to serious bodily injury or fatality. On the tool WARNING Draws attention to a potentially dangerous situation that could lead to serious personal injury or fatality. CAUTION Draws attention to a potentially dangerous situation that could lead to slight personal injury or damage to the equipment or other property. NOTE Draws attention to an instruction or other useful information. 1.
f) g) h) i) j) k) l) m) n) o) p) q) r) s) t) u) v) w) x) Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Tools and appliances create sparks which may ignite the dust or fumes. (Statement in accordance with FCC §15.21): Changes or modifications not expressly approved by the manufacturer can void the user’s authority to operate the equipment.
2.3 Proper organization of the work area Secure the area in which you are working and take care to avoid directing the beam towards other persons or towards yourself when setting up the tool. b) Avoid unfavorable body positions when working from ladders. Make sure you work from a safe stance and stay in balance at all times. c) Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials may produce incorrect results.
3.5 Automatic alignment and surveillance Using the PR 300-HV2S and the PRA 300, a single person can align the laser plane automatically with a certain point with great accuracy. The tool detects the applicable alignment (horizontal, vertical or inclined) automatically and uses the automatic alignment function accordingly (horizontal with the PRA 90 plus inclination) or automatic alignment with subsequent monitoring of the plane (vertical).

PRA 84 Li‑Ion battery Rated voltage (normal mode) 7.
5.4.1 Charging the battery in the tool 4 1. 2. 3. 4. Insert the battery in the battery compartment (see 5.1). Rotate the socket cover until the charging socket on the battery becomes visible. Plug the cord from the AC adapter or motor vehicle power adapter into the battery. The battery will be charged. Switch the tool on in order to display the charging status while charging is in progress. 5.4.2 Charging the battery when not in the tool 5 1. 2. Remove the battery (see 5.2).
6 Operation 6.1 Overview of general symbols Overview of general symbols General symbols en Activity successfully completed. Information Warning Shock warning is activated Sleep mode is activated The rotating laser is in sleep mode Inclined plane mode is activated Automatic electronic alignment is activated Manual alignment 6.2 Checking the tool Check the accuracy of the tool before using it for important tasks, especially if it has been dropped or subjected to unusual influences or impacts etc.
6.4.1 Using the PRA 300 laser receiver as a hand-held tool 1. 2. Press the on/off button . NOTE If the receiver was switched on before the PR 300 rotating laser was started, a laser beam will not yet be shown in the receiver’s display. Hold the laser receiver with the detection area directly in the plane of the rotating laser beam. 6.4.2 Working with the laser receiver in the PRA 83 receiver holder 1. 2. 3. 4. 5. 6.
Volume normal Volume low en Volume off Press the “Back” key if you wish to return to the menu. 6.5.2 Setting the units Using the units function from the menu you can set the desired accuracy of the digital display in millimeters or inches. After making each selection you are returned automatically to the normal operating mode or, alternatively, pressing the “Back” key will take you back to the menu. Units 1 mm ¹⁄₁₆" 2 mm ¹⁄₈" 5 mm ¹⁄₄" 10 mm ¹⁄₂" 25 mm 1" 6.5.
5. Activate / deactivate sleep mode by pressing the OK key NOTE All settings remain saved. . 6.5.4 Tool settings High vibration, low sensitivity to shock en Shock warning sensitivity Medium Low Percent Inclined plane mode units Degrees Thousandths Millimeters Units Inches On Wireless connection Off Settings that affect the rotating laser only become effective when the rotating laser is switched on and a wireless connection has been established.
6.5.4.2 Inclined plane mode units en Under “Inclined plane mode units” the units to be used when entering an inclination can be set to percent, degrees or thousandths. 1. Press the “Menu” key on the PRA 300. 2. Choose the “Settings” key . 3. Use the arrow keys to select “Inclined plane mode units” . 4. Confirm your selection by pressing the key. 5. Choose the correct units and activate these by pressing the key. 6.5.4.3 Units This item in the menu lets you choose between metric and imperial units. 1.
6.6.2 Alignment using the PRA 90 automatic tripod NOTE This function is available only with the PRA 90 automatic tripod. When used for the first time, the PRA 300 laser receiver must be paired with the tripod (see 6.9.2). With the optional PRA 90 automatic tripod you can set the height of the laser plane to the desired level manually or automatically. 1. 2. Mount the tool on the PRA 90 automatic tripod. Switch on the rotating laser, the automatic tripod and the laser receiver.
3. 4. 5. en Press the on/off button . After the tool has leveled itself automatically, it projects a stationary laser beam vertically downwards. This projected point is a reference point (not a plumb point) and can be used to help position the tool. Align the tool so that the projected laser point coincides exactly with a reference point (e.g. nail on a batter board). Now line up the laser plane with the second reference point manually (see 6.7.1) or automatically (see 6.7.2).
Last previously used inclination value X-axis en Y-axis The inclination can be set manually, automatically, or by using the PRA 79 slope adapter. 6.8.1 Setting up 1. 2. 3. 4. 5. 6. Mount the rotating laser on a tripod. Position the rotating laser at the first reference point either at the upper edge or lower edge of the inclined plane. Position yourself behind the tool, facing the control panel.
2. en 3. 4. 5. 6. Activate manual electronic inclination alignment on the PR 300-HV2S by pressing the “Electronic inclination alignment” key. If the arrows for electronic inclination alignment blink, the PRA 300 is receiving no laser beam from the PR 300-HV2S. If the left arrow lights, turn the PR 300-HV2S clockwise. If the right arrow lights, turn the PR 300-HV2S counter-clockwise. When both arrows light, the PRA 300 is correctly aligned.
6.9 Recalling the last previous value If you switch the tool off to reposition it, the last previous inclination value saved in the receiver can be recalled. 1. Switch the tool on again and activate inclined plane mode . The first item in the menu is the last previous value. 2. Press to select the value. 3. Check that the X and Y-values are, in fact, correct. 4. Confirm the values by pressing . The rotating laser then resets itself to the previous inclination. en 6.
ibrates the tool and checks it again to ensure conformity with specifications. The service certificate provides written confirmation of conformity with specifications at the time of the test. The following is recommended: en 1. 2. 3. 4. The tool should be checked at suitable intervals, depending on the frequency of normal use. The tool should be checked at least once a year by a Hilti Measuring Systems Service Center.
Message displayed Rotating laser in wrong position. Rotating laser shock Surveillance interrupted Receiver battery symbol Rotating laser battery symbol Tripod battery symbol Autoalignment Autoalignment not possible Receiver battery symbol Rotating laser battery symbol Fault Possible cause Remedy The tool cannot level itself. The tool is not correctly positioned – is already too steeply inclined. The tool must be repositioned in order to bring it within the leveling range.
9 Disposal en WARNING Improper disposal of the equipment may have serious consequences: The burning of plastic components generates toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and pollution of the environment.
