Drilling In Armatures; Startin-Up The Machine; Ip Protection Degree; Inclined Drilling - Sima DRILL-4 Manual De Instrucciones

WARNING: If the crown being used is new, it is very likely that it will not drill to 100% unless the
diamond bits are uncovered after the first use.
- During the drilling, keep your hands away from the crown and do not use loose garments.
- Put on the proper clothing, not too loose. Remove all the ornaments and make sure your hair is not loose.

7.7 DRILLING IN ARMATURES

Reduce the speed of the crown and the depth progress when going through metal armatures of a wall. Once
gone through, return to normal drilling conditions. The following are cases where you can identify whether the crown is
going through metal armature:
1. The crown moves slowly.
2. The force carried on the rig handle is excessive.
3. The water emanating from the drilling is clear and shows iron particles.

8. STARTIN-UP THE MACHINE

- Connect the cooling to the water tap.
- Connect the power cable to electricity.
- Press the security differential switch, integrated in the power cord.
- Press the ON switch to start the engine.
WARNING: If while using the machine, the differential switch goes to the off position, this could be as a result of a bad
isolation of the engine. In such case, stop all operations and bring the machine to the technical service for repair.

8.1 IP PROTECTION DEGREE:

WARNING: TR model Drills are built with an IP55 protection degree, allowing to work in an environment in
which there are sprinkles or jets of water.
They are not expected to work in immersion.

8.2 INCLINED DRILLING

When you have to make an inclined drilling, you start the drilling very softly because the crown at the
beginning cuts with one sector and the drilling can be not aligned.

8.3 CROWNS EXTENSION

If the drilling you wish to make deeper than the height of the crown, you will need to install an extension. For
this type of drilling, you will have to do it in twice. Consider the following steps:
1. Make the first drilling without placing the extension, only with the crown.
2. Extract the drilling stick.
3. Install the extension over the crown along with their bronze washers.
4. Make the second drilling to reach the full desired depth.

8.4 BIG DIAMATERS DRILLS

In case you need to make big diameter drills, there is an accessory that serves to remove the rig from the
motor allowing to mount bigger diameter crowns.
