●The use of an engine-driven welder as a power
source may cause your magnetic driven machine
to malfunction, Power from an engine-driven welder
can damage the electronic circuits in your portable
drilling machine.
Use a Proper extension cord.
●Do not use an extension cord that is too thin. Do
not use an extension cord that is too long. Do not
use an extension cord that is wound on a drum. Do
not share an extension cord with other motor-driven
tools. These uses can cause voltage to drop and
can reduce the holding power of the magnetic base,
causing the machine to move during operation. This
can decrease performance and may cause damage
to the machine. (Fig.7)

Don’t use this machine on the steel material being
electrically welded.
●When the electric welder is not properly grounded,
electricity will run through the Atra Ace machine
via its Magnet, causing possible failure or
malfunctioning, which in turn may cause accident.
Don’t force to feed cutter when drilling manually.
●Because the Jetbroach have rather thin cutting
edges with less cutting pressure resistance as
compared to twist drill, do not force to feed the cutter
when drilling manually.
If you feed it with too much force, the cutter may
break or end up with shorter life than otherwise.

6-4. Drilling Stacked Plates
CAUTION
●
Remove slug as each plated is finished:
otherwise, being blocked by the slug left
unremoved, the cutter cannot cut into the next
layer of plate, which results in the Magnet base
being pushed up possibly causing accident.
●
For stacked plates drilling, always feed and
drill slowly and carefully.
●
Before drilling stacked plates, securely clamp
the plates together in place.
●
When drilling stacked plates, retract the cutter
as each layer of plate is finished in order to
remove slug from the drilling area, then put
another hole in the next layer of plate.
7 HOW TO USE THE TWIST DRILL
CAUTION

tighten the drill evenly in three directions with the
chuck handle by using the three holes on the side
faces of the handle.
7-2. Drilling
WARNING
●
When drilling with the twist drill the pressing
force tends to be greater than when using
the annular blade. Be careful not to press the
workpiece so hard that the magnet lifts up.
CAUTION
When the twist drill is in use, the built-in cutting oil
supply passage cannot be used. Supply cutting oil to
the drill externally using the Jet Oiler.

9 MAINTENANCE/SERVICE
WARNING
●
Always disconnect the power and turn off the
switch before attempting any maintenance.
Failure to disconnect the power and turn off the
switch during set up, inspection or maintenance
can cause accidents and severe injuries.
●
Check to see periodically that mounting screws
are tight. If you nd them loose, retighten.
9-1. Tighten Set Screw When Machine is Not Used
For the purpose of safety, when you don’t use the
machine temporally or on a long-term basis, raise
the Drill Motor and set it in position with the Set
Screw so that it will not come down on its own
weight. If you leave the machine alone with the
Drill Motor in a lowered position, the Pilot Pin and/
or cutter may be damaged when the machine is
relocated. (Fig.31)
Before tightening the Set Screw, make sure that the
slide section in the Gearbox is properly aligned to
the head of the Set Screw.
9-2. Grease the Sliding Surfaces from Time to Time
Grease the machine body and Slide Board from time
to time. (Fig.31)
9-3. Gearbox Clearance Adjustment
Excessive clearance between the machine body
and Gearbox would deteriorate not only drilling
performance but also cutting tool life to a substantial
degree. If you find excessive clearance, make
adjustment by tightening 5 Slide Board Adjusting
Screws on the side of the machine using the same
torque all round so that the Drill Motor will not come
down on its own weight. (Fig.31)
Fig. 31
9-4. Keep the Tip of Pilot Pin Sharp
When the tip of Pilot Pin gets dull, it sometimes fails
to seat into punched hole, causing drilling accuracy
to deteriorate. See that the tip is sharp from time to
time.
If you nd it too dull, regrind or replace as required.
When regrinding do so carefully, for grinding with too
much force may cause the tip to get dull or soften
the material to such a degree that it is no longer
usable. (Fig.32)

9-5. Recovery Measures When Pilot Pin Gets
Jammed
When you change cutting tool you also change
Pilot Pin, which acts as a guide for the cutting tool.
However there are times when the pin does not
come off easy with cutting chips in the clearance
between the cutting tool and pin, causing jamming.
In such case, tap the tip of Pilot Pin with a wooden
hammer, etc., and pull it off. (Fig.33)

9-6. Cutter Regrinding
When you need to regrind cutter, please contact
sales agent through which you have purchased your
machine or an authorized dealer near you.
9-7. Carbon Brushes Inspection and Replacement
Check Carbon Brushes for wear periodically.
This machine has a "switch-off brush" which
automatically stops the motor to protect it when the
carbon brushes reach the application limits.
When the brushes reach the limits, replace both
brushes with the new ones according to the following
procedures. (Fig.34)
Check - machine failure.
(1) Remove the Brush Cap with a straight slot
screwdriver.
(2) Remove the worn-out Carbon Brush and replace
it with a new one. Then reattach the Brush Cap.
(3) After replacing the Brush, operate the unit for
about ten minutes with no load.

9-7. Carbon Brushes Inspection and Replacement
Check Carbon Brushes for wear periodically.
This machine has a "switch-off brush" which
automatically stops the motor to protect it when the
carbon brushes reach the application limits.
When the brushes reach the limits, replace both
brushes with the new ones according to the following
procedures. (Fig.34)
Check - machine failure.
(1) Remove the Brush Cap with a straight slot
screwdriver.
(2) Remove the worn-out Carbon Brush and replace
it with a new one. Then reattach the Brush Cap.
(3) After replacing the Brush, operate the unit for
about ten minutes with no load.
