Operation - Hilti AG 230-27DB Original Operating Instructions

5.2 Noise information and vibration values in accordance with EN 60745
The sound pressure and vibration values given in these instructions have been measured in accordance with
a standardized test and may be used to compare one power tool with another. They may be used for a
preliminary assessment of exposure.
The data given represents the main applications of the power tool. However, if the power tool is used for
different applications, with different accessory tools or is poorly maintained, the data may vary. This may
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the power tool is switched
off, or when it is running but not actually being used for a job. This may significantly reduce exposure over
the total working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: Maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.

6.1 Preparations at the workplace
CAUTION
Risk of injury! Inadvertent starting of the product.
▶ Unplug the supply cord before making adjustments to the power tool or before changing
accessories.
Observe the safety instructions and warnings in this documentation and on the product.
6.2 Fitting the side handle
▶ Screw the side handle into one of the threaded bushings provided.
6.3 Guard or guard with cover plate
▶ Observe the instructions for fitting the applicable guard.
6.3.1 Fitting the guard or guard with cover plate
Note
The keying on the guard ensures that only a guard designed for use with the power tool can be fitted.
The keyed locating lug also prevents the guard from coming into contact with the disc.
1. Release the clamping lever.
2. Fit the guard onto the arbor collar so that the keyed locating lug engages in the recess provided.
3. Rotate the guard into the desired position.
4. Secure the guard by closing the clamping lever.
Note
The guard is already set to the correct tension by way of the adjusting screw. If the tension is too
low when the guard is fitted, the adjusting screw can be tightened slightly to increase the tension.
