AUTOMATIC FEED SPEED SELECTOR (B-Fig. 5)
To select the feed speed, turn the side selector (B-Fig.5) to the desired feed speed
s
etting (0.1 or 0.2 m/min). To engage the feed speed, press the ON button found on the
control panel.
AUTOMATIC DOWNFEED (Fig. 8)
This drill press has a mechanical automatic feed. To set the automatic feed, proceed with
t
he following:
1. Set the depth of cut lock knob (1-Fig.8) to the desired depth and lock into place.
2. Select the feed speed (0.1 or 0.2 m/min) (2 or B-Fig.5).
3. Lift the automatic downfeed lever (3).
At the end of the stroke, the depth stop limit plate comes in contact with a limit switch
which stops the automatic downfeed. The automatic downfeed lever can also be
displaced manually to stop the downfeed before the depth stop limit plate comes in
contact with the limit switch.
AUTOMATIC TOOL EJECTOR (Fig. 9)
To remove the tool from the spindle, perform the following operations:
1. Lower the spindle manually a little bit and introduce the tool extractor (1-Fig.9).
2. Raise the spindle (2).
3. Hold the tool with one hand (3) when raising the spindle or it will fall on the table.
Attention: Do not leave the extractor bolt in the pushed-in position.
TORQUE LIMITER (Fig.10)
The gearbox is fitted with a stopping device which works in the event of overload. If the feed stops during
drilling and the tool continues to revolve, it is a sign that is it 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, reajustment may be necessary, we recommend the following action. From the inspection
hole and guided by the limiter assembly, tighten the nut bushing (parts diagram# 479). This mechanism
has been factory adjusted, by measuring the maximum admissible axial load, with a tensiometer.
Therefore, do not tighten the nut bushing too much, so as to avoid the risk of breaking the mechanism.
TRANSPARENT SAFETY SHUT-OFF GUARD (FIG.11)
Never operate this drill press without this guard (fig.11) in place. Do not modify this mechanism in any way.
This machine comes with a security micro shut-off guard. Before pressing the start button, place the drill
guard in the working position (closest position to the drill bit), otherwise the machine controls will
not start. Note: If the guard is opened when operating the machine, the machine will stop. Do not remove
the guard under any circumstances. Keep guard centered with the drill bit. This will ensure operator
protection.
COOLANT SYSTEM
This machine comes with a recirculating coolant system. Coolant is required to reduce the friction of the
cutting tool. The coolant flow is regulated using the regulator value (A-Fig.12) located at the bottom of the
coolant flex nozzle (B) on the left side of the head.
To fill the coolant system with coolant, pour coolant into the slots in the base of the machine.
The coolant
will drain into a small coolant hole in the base, near the coolant pump. Pour coolant until the coolant stops
draining into the base, turn the coolant system on by turning the coolant switch (1-Fig.4) to the right. Set
the coolant flow with the regulator valve (A). The coolant should flow normally out from the flex nozzle (B)
into the table slots, the coolant will then drain from the table back down to the base and back up through
the coolant pump and the cycle repeats itself until the coolant switch is turned of
f.
The type of coolant to use depends on the material to cut, see your local industrial distributor for more
information.

FILLING FEED BOX AND SPEED BOX WITH OIL
WARNING! THIS MACHINE IS SUPPLIED WITHOUT OIL IN THE FEED BOX AND THE SPEED BOX
FOR TRANSPORT REASONS. PLEASE FOLLOW THE FOLLOWING INSTRUCTIONS FOR
FILLING THE MACHINE WITH OIL:
The speed box (Fig.13) has an oil pump which lubricates the higher, hard to reach gears. Remove
upper oil plug (A-Fig.14). Fill with 30 grade non-detergent gear oil by using a funnel. Stop filling oil when
oil level reaches the red mark (center) in oil sight glass (B) (approx. 4.5 Liters). This red mark must
never be exceeded or the oil will overflow out of the machine. If this occurs, remove plug (C) and drain
oil until oil level goes down to red mark in oil sight glass. When the machine is turned on, speed box oil
pump turns on and fills the oil sight glass (A-Fig.13). This indicates that the oil pump is working
properly.
Fig.15 shows the feed box oil point. To access, remove the top-mounted oil plug (A-Fig.15). Fill with 30
grade gear non-detergent oil by using a funnel. Stop filling oil when oil level reaches the red mark
(center) in oil sight glass (B) (approx. 0.5 Liters). This red mark must never be exceeded or the oil will
overflow out of the machine. If this occurs, remove plug (C) under the head casting and drain oil until
oil level goes down to red mark in oil sight glass.
