TURNING MACHINE ON AND OFF
THE CONTROL PANEL
The control panel on your battery rail drilling machine is designed for maximum operating facility and
safety.
1 - The ON Switch (GREEN):
This (upper) switch is used to switch the motor unit On (“I“);
2 – The OFF Switch (RED)
This (lower) switch is used to switch the motor unit Off (“O“);
3 - The Main power Switch (WHITE):
This switch is used to turn on the main power. The indicator has two collors:
•GREEN – SAFE for use
•Alternately lightning up RED and GREEN and making a beeping sound – Not safe for use.
In order to operate properly, the machine has to be turned on following the procedure as described
below.
DRILLING A HOLE
Now that you have read the explanatory information and safety recommendations above, you are ready to
actually start drilling. Follow these steps for best drilling result:
1 Use the tip of the pilot pin to determine the center of the hole to be drilled.
2 Fasten the clamp on and verify that the drill is in the right position and that the machine is pushed
tight against the rail.
3 If your machine is equipped with an auto coolant system, open the valve to release the oil. If your
machine does not have an auto coolant system, fill the holes of the spindle with oil.
4 Turn the motor on at the highest setting and allow it to run at full speed.
5 Turn the arms to start drilling. Apply only a slight pressure when the Annular Cutter touch the metal.
Do not push the TCT Cutter with force into the metal.
6 Apply a regular pressure while drilling. The drilling performance does not improve by putting more
pressure on the feed handles. Too much pressure will overload the motor and your Annular Cutter will
break or will worn sooner. Let the cutter do the job and give it time to cut the metal!!!
7 Adjust the oil supply when necessary, if your drill does not have an auto coolant system, stop drilling
regularly, refill the holes of the spindle and continue drilling.
8 Apply less pressure when the drill cuts through the material.
9 Turn the arms to put the motor in highest position and turn off the motor unit.
10 Remove the burr, metal chips and clean the cutter and surface without getting injuries.
Caution: The metal piece drilled out can be sharp and very hot!!
DRILLING WITH TCT CUTTERS
TCT cutters only cut material at the periphery of the hole, rather than converting the entire hole to
shavings. As a result, the energy required to make a hole is lower than for a twist drill.
When drilling with an TCT cutter, it is not necessary to drill a pilot hole.
WARNING: Do not touch the cutter or the parts close to the cutter immediately after operation, as
they may be extremely hot and cause burns to the skin. Ensure nobody is in the work area where the
metal core is ejected.

12
DRILLING CONDITIONS
The ease with which material can be drilled depends on several factors including tensile strength and
abrasion resistance. Whilst hardness and/or strength is the usual criterion, wide variations in
machineability can exist among material showing similar physical properties.
The drilling conditions are dependent on requirements for tool life and surface finish. These conditions are
further restricted by the rigidity of the tool and the work piece, lubrication and machine power available.
The harder the material, the lower the cutting speed.
Some materials of low hardness contain abrasive substances leading to rapid cutting-edge wear at
high speeds. Feed rates are governed by rigidity of set-up, volume of material to be removed, surface
finish and available machine power.
LUBRICATION
IN HORIZONTAL APPLICATIONS
•Adjust the fluid flow as required using the flow regulator;
•Add more cutting fluid if the shavings (metal chips) become blue.
VERTICAL AND OVERHEAD APPLICATIONS
Dip the cutter in cutting paste or apply an appropriate spray.
LUBRICATING THE FEED TRAVEL
The feed travel should be lubricated periodically with grease to ensure smooth operation.
•Raise the motor unit to the highest position possible.
•Lubricate the dove-tail guide way at both sides.
•Lubricate the gear rack.
After repeated use, the gear rack may become loose. If necessary, adjust the 5 self-locking set
screws at the left side. Tighten screws in series until the gear rack moves freely in the dove-tail guide but
does not allow the motor to wobble.
Cleaning
CAUTION: Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting
in and around the air vents. Wear approved eye protection and approved dust mask when
performing this procedure.
CAUTION: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the
tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only
with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the
tool into a liquid.
Optional Accessories
WARNING: Since accessories, other than those offered by EUROBOOR, have not been tested with
this product, use of such accessories with this tool could be hazardous. To reduce the risk of injury,
only EUROBOOR recommended accessories should be used with this product.
Consult your dealer for further information on the appropriate accessories.

13
MAINTENANCE
Your Safetrack power tool has been designed to operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.
CAUTION: To reduce the risk of injury, turn unit off and disconnect battery pack from the
machine before installing and removing accessories, before adjusting or changing set- ups or
when making repairs. An accidental start-up can cause injury.
Just as every battery drilling machine with moving parts, your Safetrack drilling machine also needs regular
maintenance service. A few recommendations follow:
VISUALLY CHECK THE MACHINE FOR DAMAGE
Machine must be checked before operation for any signs of damage that will affect the operation of the
machine. Particular notice must be taken of the mains cable, if the machine appears to be damaged it
should not be used failure to do so may cause injury or death.
CAUTION : Clean all dirt, dust, metal chips and burrs of your drilling machine
OPERATION OF THE MACHINE
The machines operation must be checked to ensure that all components are working correctly. Replace
any defective parts immediately. This prevents properly function parts from being damaged.
ELECTRIC MOTOR
The electric motor is not serviceable and if damaged or worn out need to be replaced.
CHECK MACHINES GREASE
Replacement of grease on the gears is done at every service occasion or during repairs.
You unscrew 4 hexagon screws on the cap and loosen the motor by pulling it straight up.
Service intervals around 18 months.

14
ADJUSTMENT OF SLIDE
An essential requirement of the machine is that the slide can move in a smooth and controlled manner,
free of lateral movement and vibration.
This situation can be maintained by periodic adjustment of the slide and is accomplished in the following
manner:
1. Place the machine in an upright position and, by means of the capstan, raise the slide to its highest
position. Clean the brass rail strips and apply a small amount of light machine oil to the wear
surfaces.
2. Commencing with the top screw, loosen both setting nut (#4 on spare part drawing) with included
wrench 8 and the setting screw (#5 on spare part drawing) with included Allen key 2.5. Then gently
feed in setting screw until slight resistance is encountered. Follow your way down adjusting all
setting nuts and screws.
3. Operate the slide up and down a few times to test the movement and make any further necessary
adjustments. Try to ensure that all the screws are exerting a uniform pressure on the slide from top
to bottom. A perfectly adjusted slide will operate freely up and down without any sideways
movement.
REPAIR, MODIFICATION AND INSPECTION
Repair, modification and inspection of Safetrack drilling machines must be done by Safetrack or a Safetrack
authorized dealer. The spare parts list will be helpful if presented with the machine to the Safetrack dealer
for service when requesting repair or other maintenance.
Safetrack machines are constantly being improved and modified to incorporate the latest technological

BATTERY PROTECTION FEATURES
37V/10,5 Ah lithium-ion batteries are designed with features that protect the lithium-ion cells and maximize
battery life. Under some operating conditions, these built-in features may cause the battery and the tool it
is powering to act differently from nickel-cadmium batteries.
During some applications, the battery electronics may signal the battery to shut down, and cause the tool to
stop running. To reset the battery and tool, release the trigger and resume normal operation.
NOTE: To prevent further shut down of the battery, avoid forcing the tool.
If releasing the trigger does not reset the battery and tool, the battery pack is depleted. If depleted, the
battery pack will begin charging when placed on the lithium-ion charger.
TO CHARGE
A fully discharged battery pack with a temperature between 0° (32°F) and 65° (150°F) will charge in about an
hour.
•Use battery pack only with the recommended Safetrack charger.
•Connect the charger to a power supply. Make sure the power supply is normal household voltage,
240 volts, AC only, 50/60 Hz.
•Attach the battery pack to the charger by aligning the raised ribs on the battery pack with the grooves
in the charger, then slide the battery pack onto the charger. See Figure 1.
•Do not place the charger and battery pack in an area of extreme heat or cold. They will work best at
normal room temperature.
Note: The charger and battery pack should be placed in a location where the temperature is more than
10° (50°F) but less than 38° (100°F).
•The battery pack will become slightly warm to the touch while charging. This is normal and does not
indicate a problem.
•After charging is complete, the green LED will remain on until the battery pack is removed from the
charger or charger is disconnected from the power supply.
When batteries become fully charged, unplug the charger from the power supply and remove the battery
pack.
