INSTALLATION
• Avoid installing the machine in a humid, dirty or badly illumina-
ted environment.
• Be sure that the machine possesses all necessary protections.
• Electric installations have to be executed by a qualified electri-
cian.
• Be sure that the machine is steadily put up and positioned.
USE
• Never use the machine, if it lacks necessary protections.
• Follow applicable regulations for use of the machine regarding,
personal protective equipment.
• Do not operate the machine with loose clothes or jewelries. Use
hairnet if necessary.
• Never stretch yourself over the machine when it is running.
• Never leave the machine when running.
• Always stop the machine when not in use.
MAINTENANCE
• See to that the current is disconnected.
• Always follow the instructions in this manual.
• Do not modify the machine without contacting our dealer.
CLEANING
All bright parts of the machine are treated with rust preventive. By
removing this, be careful not to use too strong cleaning compound.
The paint might then get damaged.
INSTALLATION
The machine must be installed on a firm foundation. The basepla-
te must be levelled with washers on the foundation bolts to prevent
harmful stress when the nuts are tightened.
LUBRICATION
All high-speed shafts and gears are journaled in ball bearings or
roller bearings, so that the machine needs very little lubrication.
THE GEAR HOUSING MUST NOT BE FILLED WITH OIL.
EXCESSIVE LUBRICATION SHOULD BE AVOIDED, AS AX-
CESS OIL CAN DROP INTO THE MOTOR AND DAMAGE
ITS INSULATION.
CONNECTIONS TO MAINS
The connection should be effected directly to the thermal overload
circuit breaker or on multispindle machines to a junction box com-
mon for all drilling heads.
Note the earth screw!
(See attached wiring diagram)
SPINDLE SPEED SELECTION
The selection of the different spindle speeds according to the fron-
tplate on the drive gear box is effected by the levers on the left
hand side of the gear box and also by means of the pole change
switch for the motor.
GENERAL
IT SHOULD BE NORMAL PRAC-TICE TO DISCONNECT
THE MACHINE FROM THE MAINS BEFORE ANY DIS-
MANTLING TAKES PLACE. ON RE-ASSEMBLY, SEE TO IT
THAT ALL SURFACES ARE CLEAN AND THAT ANY BURRS
WHICH MAY HAVE BEEN MADE DURING DISASSEMBLY
ARE FIRST REMOVED.
DRIVE GEAR BOX
If you have to disassemble the drive gear box:
Remove the four screws that connect the drive gear box to the quill
hou-sing. Then take away the fan cover and the fan from the quill
housing. By knocking slightly on the rotor shaft the drive gear box
can be removed. The gear box casting, consisting of two halves
can be taken apart by loosening the four screws. All shafts can now
be taken out for further disassembling. When re-assembling the
drive gearbox, check that the shift pin fits properly into the groo-
ve of the clutch. When re-placing the drive gearbox on the quill
housing, it must be checked that the driving keys in the spindle are
in place and that they will fit properly in the corresponding key
ways on the gearbox output shaft.
SPINDLE
The spindle is journalled in the quill by a taper roller bearing at the
bottom and by a radial ball bearing at the top. At the top end of the
spindle, there is a nut with which the play in the taper bearing can
be adjusted. This nut can be reached, when the quill is removed
from the machine. Hold the spring housing by colocating a hex key
in the centre of the housing and loosen the screw. Let the housing
to relieve the pressure on the spring. The quill will then automati-
cally go to its lowest position. Remove the stop and loosen the
screw, which keeps the feed shaft in its position. Hold the quill
with one hand and push the feed drive shaft so far to the right to
disengage the teeth from the quill feed rack. Then remove the quill.
When re-assembling, the keys on the spindle have to fit into the
key ways of the spindle shaft. Take care to avoid damaging the
keys when sliding the quill into position.
COUNTER BALANCING THE SPINDLE
The spring housing for counter balancing of the spindle is remo-
ved as follows:
Hold the spring housing with a hex key and at the same time loo-
sen the looking screw, which secures it. Let the housing turn, in
order to relieve the pressure on the spring, then turn the spring
housing round in a clock-wise direction, so that the spring will be
released from the screw, with which it is fixed to the feed shaft.
The spring housing can now be removed. When re-assembling,
press the spring housing with the spring into its place and turn in
counter-clockwise direction until the spring fits to the screw on the
feed shaft. Then turn the spring housing further in counter clock-
wise direction, until the correct balancing of the spindle is obtai-
ned. Then lock the housing with the screw.
MOTOR
If it is necessary to remove the stator, proceed as follows:
DISCONNECT THE MACHINE FROM THE MAINS.
Remove the drive gear box, the quill and the feed drive shaft as
indicated above. The motor and the line cables are removed from
the pole-change switch. Secure the quill housing with a lifting
band. Loose the screw and lift off the quill housing. Then remove
the elevating mechanism for the drilling head. The two step scre-
ws on the left side of the quill housing, keeping the stator in its
position, are removed and the position of the stator is marked in
the housing. By knocking lightly on the underside of the quill
housing against a suitable surface the stator will slide downwards
out of the housing. The new stator is then pressed into the housing
from below in the same position as the previous one.
