Preparation for Operation
The following procedure is recommended for the correct drilling using the Brobo Group Drill
.
PROCEDURE
1) Clean the workpiece to ensure it is free of any grit, swarf or flammable substances. It is highly recommended
that a solvent is used to remove any residue while ensuring the solvent is inflammable and non-toxic.
2) Prior to drilling, clear the drill & the work area around the workpiece of any swarf or/and tools to minimise
the likelihood of the user getting injured during the drilling operation.
3) Load the workpiece into the mechanical vice (sold separately), located on the rack lift, & fastened workpiece
securely. Loosen the rack lift & adjust the height & horizontal position. Once you have positioned the
workpiece into the desired location, relock the rack lift assembly.
4) Check that the correct speed drill speed setting is selected, & the safety eye shield is directly positioned to
deflect swarf & any dislodged particles.
5) Turn the machine on. Proceed by slowly drilling into the workpiece until a guide indent is created. Steadily
increase the feed rate of drilling by applying a constant yet steady force on the feed handle until the desired
hole depth is reached.
6) Reverse the direction of the drill fed until it comes to rest in its start position & turn the drill machine off.
Operation Recommendations
To reduce the amount of frictional contact between the drill bit & workpiece, a light coating of oil or lubricant
can be applied to the drill bit price to drilling.
Do not force the drill bit through the workpiece as this significantly reduces the lifespan of the bit, as well as
increasing the risk of the bit bending and/or breaking & injuring the operator.
When drilling through larger hole diameters through thick materials, it is advisable to split the drilling
operation into two or three stages, starting from drilling a smaller hole size & increasing it until the desired
final hole size.
WARNING – SAFETY GEAR
Protective clothing, safety glasses and gloves should always be worn while loading
parts, operating the machine, or undertaking any maintenance work on the machine.
WARNING - JAMMING
If the drill jams during a drill, engage the EMERGENCY STOP immediately. Remove the part,
check that the drill bit is not damage and if need be, replace the drill bit.

2.3. Advice for the Operator
Protective eyewear or goggles must be worn at all times while attending & operating the drill.
Do not attempt to operate the machine unless all safety guards are in operation.
Ensure that hands & arms are kept clear of the drilling zone when the machine is operating.
Do not wear loose clothing with long sleeves & oversized gloves, bracelets, necklaces or any
other loose object that may become entangled in the machine’s tooling bit during drilling. Long hair
must be tied back or placed in a hair net.
Always disconnect the power supply to the machine before carrying out any maintenance
work or adjustments. This includes cases of abnormal operations of the machine.
Any maintenance work performed on the hydraulic, pneumatic or coolant systems must be carried
out only after the pressure in the system has been released.
The operator MUST NOT conduct any risky operations or those not required for the drilling in course
(e.g. remove swarf shavings from the machine while drilling).
Never move the drill while the machine is operating.
Always keep the workplace are as clean as possible.
Remove equipment, tools or any other objects from the drilling zone.
Support the workpiece to prevent it falling or jamming during the drilling cycle.

If the drill bit is jammed during a drill, activate the emergency stop function immediately. Do
not continue forcing the drill bit through. This could damage the drill, the specimen or be a cause
for potential injury to the operator.
Always turn off the machine before carrying out any repair work. Consult the Brobo Group
Engineering Department in the country in which the machine was initially purchased.
Machine Safety Devices
This product & maintenance manual is not purely intended as a guide for the usage, operation, & maintenance of
the drill unit in a strict production environment; it is instead an instrument to providing information on how to use
the machine correctly & safely. The following standards which are applicable to the Brobo Group Drill, are those
specified by the EEC Committee that governs the safety of machinery, health & safety at work, personal protection
& safeguarding of the work environment. In addition, the drill also complies with the Australian Standards
regarding the safeguarding & general requirements for electrical equipment.

3. Main Applications and Features
Applications include drilling, spot facing, chamfering, reaming, tapping and boring.
The headstock and worktable are easily adjusted, the headstock and worktable can be
moved up and down and be rotated 360° around the vertical column.
The headstock and worktable can also be leaned ±90° and spun 360°.
Depth of drilling is ensured by a scale fixed on the sleeve and a setting nut.
Tools/arbors are easily changed using the tool retracting dial.
4. Transmission System
(As show in Figure 2)
The spindle has 6 different speeds which is driven by a motor shaft I through gears 6 & 7 to
shaft II, and gear 2 to gear 3, 4 & 5 to shaft III, then gear 1 to gear 8 to spindle.
Spindle feeding downward is performed by gear 9 driving rack of spindle sleeve, and
reposition of spindle sleeve can be performed automatically by spring fix adjustment on
gear 9.

6. Lubrication
Top up lubrication oil No. 30 to the headstock every 6 months, the lubrication oil should be
added once a week (ball valves), reference figure 5 for the location of lubrication.

7. Lifting and Installation
All locking handles must be locked before lifting (Lifting point shown in figure 6).
When installing the machine, bury the foot-screw in a cement foundation according to the
position of base holes, after the cement has condensed completely, place the machine on
the cement foundation and secure to footing screws.

MAIN SPINDLE CONTROL
Main Spindle Control has “forward, reverse and stop” positions.
ADJUSTING HEADSTOCK
By loosening the lock handle (11) & turning handle (7), the headstock can be moved up and
down.
Loosening the lock nuts on the headstock allows the headstock to be leaned ±90º. Make
sure to lock the handle (11) and all lock nuts before operating the drill.
Adjust return spring by adjusting spring in figure (9), loosening the handle (2) and turning
spring base (1) allows the adjustment of spring force, lock handle (2) once you have desired
force of spring return .
ADJUSTING SPINDLE FEED
Turning the handle towards you (1) will drive the spindle downward. Loosening the handle
(8), the spindle automatically is returned under the spring force.
ARBOR/TOOL RELEASE
Turning the dial (12) to the “↓” position and pushing the handle (1) upward will allow the
arbour/tool to be removed. Turning the dial to the “↑” position will allow the arbour/tool
to be installed again.
DEPTH DRILLING
Turning nut (9) to adjust block (6) allows adjustment of depth control of drilling.
ADJUSTING WORKTABLE
Loosening lock handle (14) and turning handle (13) allows the worktable to be moved up
and down.
Loosening the lock handle (14) also allows the supporting block together with the worktable
to be rotated 0-360° around the column.
Loosening lock handle (10) allows the worktable to be rotated 360°
The working table can be leaned ±90° after loosening nuts (16).
