Electrical Connection

Before starting the machine, please check the correspondence between voltage and frequency against the data mentioned on the identification plate. Voltage differences of + 6 % and – 10 % are allowed.
The Hand-Held Drilling Machine is made in protection class II. Only use extension cables with a sufficient cross section. A cross section which is too small could cause a considerable drop in performance and an overheating of machine and cable.
Recommended minimum cross sections and maximum cable lengths

Additional Handle

When using the machine handheld than only with its additional handle.
For mounting, screw it in the thread on the gearbox housing and fix it tightly.

Tool Protection

Wrong handling can cause damages on the tool and injuries of the user.
Therefore, the following instructions should be observed:
Do not allow blocking of the tool.
Only use original accessories made by EIBENSTOCK.

Switching on and off

Short-Time Operation
Switching-on: press the on/off switch
Switching-off: release the on/off switch
Permanent Operation
Switching-on: press the on/off switch and, keeping it pressed, engage the lock-on button
Switching-off: press the on/off switch and release it again
Attention!
Only press the lock-on button when using a stand. In case of every stop of the machine, the lock-on button has to be released immediately by pressing the on/off switch.
Consequently, you can avoid an unintentional restart of the machine (physical hazard).
The machine is equipped with two selecting wheels, which allow an adjustment of load speed and torque.
These are in the intermediate block between handle and motor housing.
The speed adjustment (SPEED) is on the same side like the arrestor button.
Torque adjustment (POWER) is on the opposite.
Additional the machine has a change-over switch for reverse action.
It is on the top side between the selecting wheels.
Use the change-over switch only when the spindle is stopped.

Mode of Action of Speed Adjustment

Position “I” means minimum, position “IIIIIII” maximum speed.
Please pay attention that a permanent use with reduced speed can cause an overload because the motor then gets less cooling air and therefore the machine will be overheated much faster.
So always use preferably the mechanical speed selection for changing the speed.
Mode of Action of Torque Adjustmen t
As well as with the speed adjustment position “I” means minimum and “IIIIIII” maximum. Position “I” is 1.1 times and position “IIIIIII” is equal to the 2.4 times of the rated torque, both at maximum speed. Drilling in controller stage 7 must be avoided in manual mode.

Changing Gears

The machine is equipped with a mechanical two-speed gearbox.
Select the required speed by pressing-in, shifting and engaging. The position of the lower speed is in direction of the working spindle. Change the speed only when the machine is not running, and support the speed- changing by slightly rotating the work spindle.

Overload Protection

In order to protect the operator, the motor and the drill bit are equipped with a mechanical, electronic and thermal overload protection.
Mechanical:
If the drill bit is suddenly blocked in the hole, a clutch will slip disengaging the bit from the motor.
Electronic:
In case of overload due to too large feed force, the electronic will cut OFF the machine. After discharge and switching ON you can continue drilling again.
Thermal:
By means of a thermal element, in case of continuous overload, the motor is protected against destruction. In fact, the machine switches OFF automatically and only can be switched ON again after a certain cooling period (about 2 minutes). This cooling period depends on the warming of the motor winding and ambient temperature.

Instructions

Only use faultless and sharp drilling tools and avoid that the machine stops due to overload.
Mounting the tool
Disconnect the plug from the mains before every tool change!
Twist drills:

• Drills with MT 3 connection can be directly fit in the drill spindle.
• For twist drills with MT 2 connection use a reducing sleeve MT 3 – MT 2.
• For twist drills with parallel shank use a drill chuck B18 with appropriate taper mandrel MT 3 – B18.

Core drills:

• For working with core drills you need a mount MT 3 – Ø 19 Weldon.
• Fit the ejector pin of suitable length in the core drill.
• Place the core drill in the Weldon mount so that the two Allen screws hit the two surfaces of the shaft.
• Tighten the Allen screws equally.

Attention!
Never press the tool into the tool connection with might and main!
Morse tapper and – cone have to be free of grease and dirt.
Removing the tool
Put the drill drift in the opening of the gearbox collar.
If you cannot insert the drill drift through the work spindle, turn the work spindle slightly.
Remove the tool from the work spindle by a slight impact on the drill drift.

Safety Clutch

The safety clutch should absorb shock and excessive stress. It is an aid and not an absolute protection. Therefore you have to handle and drill carefully.
To keep it in good condition, the clutch should slip for a very short time (max. 2 seconds) in each case only. After excessive wearing the clutch has to be renewed by an authorized service shop.

Care and Maintenance

Before starting with the maintenance- und repair works you have to disconnect the plug from the mains.
Repairs have to be carried out only by qualified and due to education and experience suited personnel. After every repair the machine has to be inspected by an electric specialist. Due to its design, the machine needs a minimum of care and maintenance. The following works have to be carried out regularly:

• The electric tool as well as the ventilation slots always has to be clean.
• During work, please pay attention that no foreign elements get into the interior of the machine.
• In case of failure, a repair has to be carried out by an authorized service workshop.

Our after-sales service responds to your questions concerning maintenance and repair of your product as well as spare parts.
EIBENSTOCK’s application service team will gladly answer questions concerning our products and their accessories.

Environmental Protection

Raw material recycling instead of waste disposal
In order to avoid damages on transportation, the power tool has to be delivered in sturdy packing. The packing as well as the tool and its accessories are made of recyclable materials and can be disposed accordingly.
The tool’s plastic components are marked according to their material, which makes it possible to remove environmental friendly and differentiated because of available collection facilities.
Only for EU countries
**** Do not dispose of electric tools together with household waste material!
In observance of European Directive 2012/19/EU on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

Noise Emission / Vibration

The indication of noise emission is measured according to EN 62841-2-1.
The level of acoustic pressure on the work place could exceed 85 dB (A); in this case protection measures must be taken.
Wear ear protectors!
The typical hand-arm vibration is below 2.5 m/s².
Measured values determined according to EN 62841-2-1.
The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Dust protection

Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic such as oak and beech dust especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists.

• Where the use of a dust extraction device is possible it shall be used.
• The work place must be well ventilated.
• The use of a dust mask of filter class P2 is recommended.

Warranty

According to our general terms of delivery for business dealings, suppliers have to provide to companies a warranty period of 12 months for redhibitory defects (to be documented by invoice or delivery note).
Damages due to natural wear, overstressing or improper handling are excluded from this warranty.
Damages due to material defects or production faults shall be eliminated free of charge by either repair or replacement.
Complaints will be accepted only if the tool is returned in non-dismantled condition to the manufacturer or an authorized Eibenstock service centre.
