1. SAFETY RULES
Information in this manual on the safe use of the provided equipment does not release the
operator from following safety regulations in force on site.
In addition, the operator should have an information on the necessary safeguards as defined
in relevant national and international standards and regulations.
It is forbidden to use the equipment without previous reading of this manual.
This symbol is dedicated for tips not using of which may be dangerous to life or health. These tips
should be used while keeping special caution in these situations. These tips should be given to all
users of the device.
1.1 INTENDED USE
Hand grinder for tungsten electrodes SPARTUS® D33 is dedicated for sharpening of tungsten
electrode tip (non-consumable electrode), use for TIG welding procedure.
It is forbidden to grind tungsten electrodes with thorium without first connecting the extractor
and separating the dust with proper filtration. The dust generated as the result of the grinding
ofthorium electrodes is highly harmful to health and life of the operator..
It is forbidden to use the device for improper purposes!
1.2 SAFETY USE
Before each use check the condition of the device and additional accessories. It is forbidden
to use damaged or technically inoperable device. Used and damaged parts must be replaced
with original spare parts.
Breaking the safety rules may lead to the risk of losing health or life!
1.2.1 Eye and face protection
The wheel rotational speed reaches 1100 rpm. During the grinding, splinters and impurities
that can form in the eye may appear. High temperature can be produced due to strong friction
forces. The rotating wheel of the grinder can pose a risk to the operator’s hands and fingers.
In order to prevent hazards mentioned above and other risks that accompany the grinding
process, the following rules must be followed:
• it is absolutely forbidden to use the device when the protective cover is removed or damaged,
• it is forbidden to put hands or fingers inside the grinding chamber when the device is con-
nected to the electricity supply,
• sharpened electrode always should be secured by a clamp.

1.2.2 Noise load
The device itself emits a low level of noise. However, during the sharpening of tungsten elec-
trode, the level of noise increases. Excessive noise can cause permanent damage to hearing.
In order to prevent threats mentioned above, following rules must be followed:
• use appropriate hearing protectors,
• people in the vicinity should be informed about the dangers of exposure to excessive noise.
People in the work zone must wear appropriate hearing protection.
1.2.3 Risk of electric shock
The unit is powered from single-phase network 230V +/- 10%. Like all device supplied with
electricity network, the grinder may cause risk of electric shock to the operator. Electrical
shock from the electricity network can result in permanent damage to health or loss of life.
In order to prevent threats mentioned above, following rules must be followed:
• it is forbidden to use when the power cord, plug or cover is damaged,
• do not touch electrical components of the device under voltage,
• take special care when using the device in small rooms or in areas with increased air humidity,
• avoid contact with water.

6. INSTALLATION AND USE
Situations and threats that may cause direct danger during use of the device.
Precautions to be taken by the operator in order to avoid hazards!
Health-impaired materials that electrodes are made of!
Tungsten electrodes can contain harmful materials. Follow the manufacturer’s instructions and
recommendations! In case of doubt concerning the composition of tungsten electrodes contact
the manufacturer / supplier of electrodes.
Activation with an electrode applied to the grinding wheel!
Launching and commissioning of the device with an electrode applied to the grinding wheel may
cause twist of the electrode and damage the grinding wheel, the equipment and personal injury!
During the launching, the electrode must not adhere to the surface of the grinding wheel. Check
the electrode position before switching on.
Open supply channel!
During the grinding procedure splinters and dust which can fall into the eye or be released into
the air can get through a supply channel.
Prior to switching on the device, place the electrode holder in the supply channel. Keep in mind
that the end of the grounded electrode should not touch the grinding wheel.
After turning off, wait until the grinding wheel has completely stopped before pulling out the
electrode holder from supply channel.
Too much clamping force between electrode and grinding wheel!
Using too much clamping force on grinding wheel can cause overheating and an annealing of
electrode. Annealed electrode may be unusable or damage the device.
Do not use too much clamping force between electrode and grinding wheel!
Rotate the electrode evenly over the grinding wheel during sharpening!
Before each use make sure that all components are properly installed and technically functional.
It is forbidden to use the device if it is technically inoperable!
The unit is powered from single-phase network 230V. RISK OF ELECTRIC SHOCK. Connect to
asingle-phase network with the parameters indicated in the technical documentation. Check
the status of plug and power supply lines. Replace the damaged power supply line or plug with
anew one!
