Attention! The machine is supplied without oil for
transport reasons.
The top speed box incorporates an oil pump to
lubricate the gears. Remove the upper plug, Fill
oil by using a funnel. Stop filling oil when oil level
reaches the red mark on level window.
The Lower feed box is just an oil bath type oiler,
Remove plug in the top of the feed box and fill as
needed to the red mark on level window
These red marks must be never exceeded; as
otherwise, the oil will overflow out the machine.
If this occurs, remove plug and drain oil until oil

AUTOMATIC FEED
Models incorporate mechanical automatic feed.
The way to proceed is the following:
1. -Regulate the stroke at the depth top.
2. -Select the feed.
3. -Place the lever of the automatic feed.
At the end of the stroke, the depth top displaces
the lever of the automatic feed.
The lever can also be displaced manually.
TORQUE LIMITER
The gearbox is fitted with a stopping device
which works in the event of overload.
If the feed stops during drilling and the tool
continue to revolve, it is a sign that it is
overloaded.
When the load is reduced, the feed starts up
again.
If for any reason, such as due to wear of the
limiter discs or the need for a higher working
load, it is required to readjust it, we recommend
the following action.
---From the inspection hole and guided by the
limiter assembly shown on page 17 tighten the
nut Z5040.03-56 (index No.79)
This mechanism has been adjusted in our
works, by measuring the maximum admissible
axial load, with a tens meter. Therefore, do not
tighten the nut too much, so as to avoid risk of
breaking the mechanism.

SAFETY AND GENERAL INFORMATION
1.SAFETY:
A drilling machine, due to its purpose, is considered an “open
machine ”Therefore, some safety measures have to be taken to avoid
accidents.
Bear in mind the following safety instructions:
The machine must always be operated for the purpose for which was
designed.
Do not ever stand under a hanging machine or nearby, when it is been
loaded for transportation.
Connect the machine to an exclusive electric connection, which includes s
differential switch of protection. Plug in first the green-yellow protection
wire and then the others.
The piece must always be fastened with suitable devices. Do not ever
handhold the pieces.
Sharpened tools in good condition must always be used.
Appropriate tools must always be used, Do not ever adapt a tool for a use
for which it was not designed.
Use the correct speeds and feeds for the material being machined as well
as for the tool being used.
Use glasses to prevent small chips from getting in the eyes.
Insert the tools correctly in the tool holder cone.
Fix the piece fastening devices to the machine table.
Do not wear baggy clothes, loose gloves, etc, which can be caught by the
tool while drilling.
Keep the working place clean.
Gather the chips with suitable instruments (brush, gloves, etc.).
Before carrying out any operation which is not strictly drilling, tapping etc.
(like Iubricating, changing of tools, etc.) turn the main switch to the
“0”positon.
Before changing speeds, stop the machine and wait until all moving
elements are completely brought to a halt.
Do not ever leave the machine on without supervision. When leaving the
machine, check that the general switch is in the “0”position and that
moving elements are stopped.
Check periodically the correct operating of all security controls and
elements of the machine.
Before pressing the starting pushbutton, set the dill protector guard in the
working position.
Consider work area environment. Don’t use electric power driven tools in
damp or wet locations. Keep work area well lit. Don’t use electric power
tools in presence of flammable liquids or gases.

Keep children away.
Use only such accessories and attachments as are recommended in the
operating instructions or the catalogue for the power tool concerned.
2. FORESEEN USE OF THE MACHINE
The drilling machine was designed to be used with specific tools and for
certain machining operations.
The most common machining operation is the drilling of holes with helicoidal
drills. The drilling of hole is carried out by the combination of a drill turning
movement and a feed movement in the turning spindle direction.
Besides the helicoidal drill, other tools can be used to drill holes. There is a
great variety of drill types and shapes in the market which can be used on this
machine, provided that they are designed for such a purpose and that can be
fixed in the spindle taper. They will usually be the Morse taper or ISO type. The
drill shanks should have the corresponding taper to the spindle in which they
are to be fitted, or parallel shank if they are going to be fitted by means of a tool
holder. Contact the tool manufacturer for any further information. Do not ever
use tools which were not designed to be used in a drilling machine and that
have been adapted.
A drilling machine can also perform other machining operations a part from the
drilling, such as tapping, reaming, chamfering, punch marking, countersinking,
spot facing, to perform such operations, it is necessary to have appropriate
tools, specially designed for this sort of jobs. In the tapping case, besides using
correct tool, the machine has to be provided with such a device that verses the
turning direction of the tool when it reaches the depth previously fixed.
3.CORRECT USE OF THE MACHINE
Not exceeding its working capacity.
Operating the machine by qualified and trained staff and according to the
points mentioned in the instruction book.
Working under the safety systems provided with the machine, checking
them and keeping them.
Watching the safely measures mentioned in the instruction book and
notices on the machine.
Wearing clothes which provide personal as mentioned in the instruction
book.
Watching the safely measures which may affect work in the machine and
that can be lawfully expected, as well as those demanded in the
workshops.
4.PIECE CLAMPING.
Tangential cutting forces and axial forces in the feed direction of the tool are
Page 31
Instructions Manual for GHD-38B (D1325)
26/06/2017
OWNER’S MANUAL
Page -30 -
mainly produced during the drilling process. The tangential forces produce a
moment of forces which make the piece being drilled turn. Therefore, the
pieces to be drilled (or to be machined by one of the operations mentioned
above) must be clamped in an appropriate device such as a drill chuck and the
drill chuck must be correctly clamped to the machine table. For this reason the
machine tables are provided with “T” slots.
The pieces must be clamped conveniently by some clamping device.
The clamping devices in turn must be clamped to the machine table.
The machine table is provided with “T” slots for such purpose.
5.TOOL FIXING.
The tools generally used in this machine will have parallel or taper shanks.
Drill holders are normally used to fix to the main spindle of the machine the
parallel shank tools. This fixing device is used for small drill diameters (max. up
to dia.16mm). Bigger diameter drills, usually have taper shank of Morse taper
(the ones of smaller diameters to 16mm can have taper shanks).
The housing in the main spindle to insert the tool is of Morse taper type. It is
very important to insert the tool taper correctly in the main spindle taper to
avoid the tool falling from its housing when turning and provoke an accident.
The coupling system itself of the tool male taper in the female taper of the main
spindle is auto-locking, but for it the surfaces of the tool taper and spindle taper
must be in contact. To get the best possible contact, the surfaces of the tool
taper as well as the spindle taper should be in good conditions. Therefore, it is
advisable to handle the tool as well as the spindle of the machine carefully.
6. CHIPS DURING MACHINING
The machining process removes material from the piece. This material is
released in chips, which can be of different shapes depending on the material
itself. The most common ones are of three types: fragmented chips in small
bits, short helicoidal chips and long helicoidal chips.
The chips fragmented in small bits can be rejected from the machining area
and can be dangerous if they reach the eyes of the operator. To avoid this, it is
advisable to wear safety glasses.
The long helicodal chips tend to roll up the tool and gain considerable volume
before breaking, which is dangerous if they reach the operator as they may
produce injuries.
The reached volume may also displace the dill protector from its security
position, increasing the risk of an accident. It is advisable to use chip breaking
tools to machine materials which produce such chips. For further information
contact the tool manufacturer.

the clock if properly operated and maintained. Machine must be lubricated and
checked for adjustment before operation. Improper lubrication or loose nuts
and bolts can cause excessive wear and dangerous operating conditions.
1. Check the machine prior to operation for any missing parts or broken shear
pins. Refer to the manual before attempting to lift the machine.
2. Newly installed machine should be properly leveled before any operation
to prevent vibration and wobble.
3. When the machine is transported out of a normal shop environment should
be protected from dust, excessive heat, and very cold conditions.
4. Change the lubricant frequently if working in dusty conditions.
5. In hot working areas, use care to avoid overheating the motor of damaging
any seals.
6. Operate the machine at slower speeds than normal when working in cold
environments.
7. During the operation, the chips that fall onto the table surface should be
cleaned timely.
8. After the operation every day, eliminate all the chips and clean different
part of the machine tool and apply machine tool oil to prevent rusting.
9. In order to maintain the machining accuracy, take care of the center, the
surface of the machine tool for the chuck and avoid mechanical damage
and the wear due to improper guide.
10. If the damage is found, the maintenance should be done immediately.
ATTENTION: before performing any checking, repairing or maintenance
operation, switch off the main switch and make an additional check to ensure
that the machine is not under voltage.
Oil, grease and cleaning agents are pollutants and must not be disposed of
through the drains or in normal refuse Dispose of those agents in accordance
with current legal requirements on the environment. Cleaning rags
impregnated with oil, grease and cleaning agents are easily inflammable.
Collect cleaning rags or cleaning wool in a suitable closed vessel and dispose
of them in an environmentally sound way-do not put them with normal refuse!
