- Keep available an extra vibrator needle as needles often need repair and change. During the laying of slab, there is no time available to bring a new needle. Choose a vibrator with 40 mm diameter needle and with a long flexible portion, preferably 5 to 6 metres long to avoid its frequent shifting.
- While compacting concrete with vibrator, keep the needle in vertical position. Don't try to push concrete with the vibrator-needle. For more tips, see the Hindustan Times of 21.10.07
