Dismantling
To change the head, the two rear screws must be removed and, due to the precise match and use, it may
be necessary to give a light knock with a plastic mallet on the top/front part of the support.
Cleaning
Periodically clean the drilling group of machining waste, using compressed air and a cloth with ethylic
alcohol.
Lubrication
The drilling groups are supplied already lubricated. During the first hours’ work, there may be a loss of
lubricant due to an excessive amount having been applied.
Every 200 machining hours, grease with 5 grams of “MOBIL SHC100” grease.
Consignment / Unpacking
The support of the
CMT333
head is supplied packed in a handy case, in which the head chosen and
three bits can also be placed.
When the product is received, check that the contents correspond exactly to the items ordered and that
nothing has been damaged during transport.
In the event of any obvious defects being noted, do not use the set, but immediately inform the manu-
facturer.
No lifting equipment is required for handling the set, as it is light-weight (<20 kg).
Storage
In the event of the product having to be stored, proceed as follows:
- Clean of any machining scrap.
- Protect ground parts with a coating of grease and/or liquids for protection against corrosion or rust.
- Store in a fresh dry location at a temperature of between -5° and 30° C.
- Protect the drilling group from dirt and dust.
- If stored for over six months, before use, it is advisable to replace the lubrication grease.
Safety
During machining, always use personal protection: hearing protection device, dust mask, protective gog-
gles. Never wear loose garments, make certain sleeves are rolled up and do not wear ties.
Follow the regulations described here scrupulously. The manufacturer is exempt from all responsibility in
the event of failure to comply with instructions and indications. The system must not be used in any other
way than that for which it is intended. Cleaning, lubrication and maintenance work must never be carried
out on the system when the drilling group is running.
If unusual noise or vibrations are noted with the system is started, stop machining and contact our Te-
chnical Office.
MAINTENANCE & SAFETY
7
According to the hinge model, install the relative chuck
head
(Fig. 2)
on the multipurpose support
(Fig. 1)
by
means of the two rear locking screws
(1)
.
Position the drilling system on a work surface suited
to the type of machining. Procure a steel bar with a
diameter of Ø10mm (3/8”) and a length suited to
the type of machining to be carried out and fit it in
the side hole
(2)
. Adjust the reference stop and lock
everything with the two clamp knobs
(3)
and fix one
or more reference shims on the table according to the
length of the workpiece to be drilled
(Fig. 4)
.
Set drilling distances
(Fig. 3)
: From the panel’s edge
to the hinge
(D)
by means of the plate and centre
clamp knob
(4)
and the drilling depth
(H)
with the
threaded bar and lock nut
(5)
, then position the
workpiece to be drilled
(Fig. 4)
. The bits suited to the
head chosen are then fitted to the three arbors: on
the centre arbor
(6)
fit and lock the Ø35mm bit for ri-
ght hand hinges, whereas, on the two side arbors
(7)
,
fit left-hand Ø8mm or Ø10mm bits for blind holes.
(according to the type of hinge), which are fixed with
the two dowels,

Use
Use is easy and rapid. Once the equipment is ready, all that has to be done is to fit the shaft of the drilling
system
(8)
to the arbor of a normal electric or battery-powered column drill and carry out the drilling.
Drilling speed depends on the work piece and the type of bit used.
Maximum rotation speed: 5000 rpm.
N.B.:
Before starting the drilling system, check that the tools are correctly tightened and direction of
machine rotation, to ensure that the tool turns in the correct drilling direction.
