erughaalveer
Ga als volgt te werk om de terughaalveer te spannen:
• Laat de spindelhuls uitlopen totdat de tanden van de wielen makkelijk in
elkaar kunnen grijpen.
• Draai de hendel in de aangegeven richting.
• Draai de schroeven in de plastic afdekking los en draai de afdekking naar
rechts. Wanneer de veer gespannen is, moeten de schroeven weer worden
aangedraaid.

verbelastIngskoppelIng
In de tandwielkast bevindt zich een overbelastingskoppeling die in geval
van een overbelasting in werking treedt. Wanneer de voeding stopt maar het
gereedschap draait door, dan is dat een teken dat de machine overbelast is. De
voeding start opnieuw wanneer de belasting wordt verminderd.
Door bijvoorbeeld slijtage van de begrenzerschijven of door de behoefte aan
een grotere werkbelasting kan Het nodig zijn om de overbelastingskoppeling
opnieuw af te stellen. Laat dit afstellen uitvoeren door een gekwalificeerd
monteur.

SPEED SELECTOR
By means of levers spindle speeds are selected. Left lever
selects a colour. Depending on the color selected, right
lever selects a spindle speed value. For moving these
levers, slightly pull them and the rotate.
FEEDS SELECTOR
To select the feed speed, turn the side selector until the
required point (value).
AUTOMATIC TOOL EJECTOR
To remove the tool from the spindle, perform the following
operations:
1.
—
Lower the spindle from the reels a little bit and
introduce the extractor bolt .
2.
—
Raise the spindle from the reels.
3.
—
Hold the too with the hand when raising the spindle or
it will fall on to the table.
ATTENTION:
Do not leave the extractor bolt introduced.
RETURN SPRING
To tauten the return spring in model extract the quill until the
teeth of the working gear can move freely .Then move the

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
Z5035-03-21.(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 the risk of breaking the mechanism.

ELECTRIC CONNECTION
The electric connection is a dangerous operation. This task must be
carried out by trained or authorized staff for such purpose.
WARNING: The electric cabinet of the machine does not include the
protection differential switch. The user must install an individual
power supply for the machine,
including a protection differential switch
of 0,300 amps sensibility and the earth
connection.
The present machine has a 4 wire
electric hose to connect it to the
electric power supply through a
protection differential switch. Do
always connect the PE protection wire
first and after that all the others.
Connection voltage: the features sheet
shows the voltage the machine must
be connected to.
Total power installed: 1Kw.
WARNING: Once the electric
connection has been made, make sure
