1-2 Helmet and Head harness Adjustment
Please make the appropriate adjustment(s) to the head harness to ensure a
comfortable and secure fit. It only takes a minute and helps ensure you are properly
protected. The ServoGlas 4000 harness allows you to adjust the distance and angle
between your eyes and the filter window.You can also adjust the circumference of the
headband to ensure a comfortable but firm fit. Please make these adjustments
before use based on the illustrations in figures shown below.
The auto darkening welding filter in the SV4000 has been designed for arc welding and gas
cutting. It is suitable for all normal arc welding processes such as MIG, MAG, TIG, SMAW,
Plasma Arc and Air Carbon welding.
Before use the shade control should be adjusted to the appropriate level based upon EN169
(European Standard specifications or equivalent) or other appropriate safety guidelines. When in
doubt please consult your safety representative or your authorized Servo Glas 4000 distributor.
The Servo Glas
4000 provides continuous protection from ultraviolet and infrared radiation to
the maximum level indicated on the product and as described in the relevant Standards. This
protection is fail-safe and is not compromised by loss of battery power or other electronic failure.
The Servo Glas
4000 welding filter cartridge is fitted with two independently operated sensors
that detect the welding arc and respond accordingly resulting in the appropriate darkened filter
state as set by the user and as indicated on the scaled adjustment. Please note that professional
judgement may be required to achieve the best results. When in doubt consult an authorized
safety representative or your Servo Glas
distributor and always maintain a conservative
attitude towards operation.
Two replaceable lithium batteries type CR2032 (3V) are used as major power sources. An
additional solar cell panel extends battery life and ensures efficient operation. When operating
normally the welding helmet will switch on automatically and switch off automatically to save
power a few minutes after the last welding arc has been detected.
To provide a general check of system status you may wish to set the shade control to 11 and
hold the helmet towards a bright incandescent light source. Under normal circumstances the
filter will change from light to dark state and back to light state again as you move the helmet
away. Please note that if you have any questions or there is any doubt about the performance of
your Servore product you should refer to your authorized safety representative or Servo Glas
distributor.

5-1. Shade Control
The required filter dark state can be selected by
using the shade control. The ServoGlas 4000
can be adjusted between shades 9 to 13 with
the embossed arrow on the dial indicating the
current adjustment.
Always use the appropriate shade for the
welding operation you are undertaking. When
in doubt please consult the relevant Standards
or your authorized safety representative.
Recommended shade numbers according to BS 679, DIN 4647-1 and EN169
According to the conditions of use, the next greater or the next smaller scale number can be used.
5-2. Light Sensitivity Control
Where problems are experienced during welding at low currents
[e.g. TIG] or there is a high level of ambient light please follow
these steps: First try adjusting the sensitivity control switch. If
this does not solve the problem hold the helmet close to the
target object and adjust the shade control completely clockwise.
If the welding filter continues in the bright state, leave the control
set at this point. If the filter changes to the dark state, turn the
shade adjustment knob until the filter just switches into the light
state. The filter will then be adjusted correctly. If the welding
filter still does not respond appropriately please try adjusting the
sensitivity control again (having previously adjusted the shade
control as explained above)
Adjustment of the speed at which the welding filter clears
can be reduced by means of the delay control toggle switch.
When this switch is set to 'Fast' the screen will clear more
quickly.

SERVO GLAS4OOO
Your Servore welding helmet is strong and durable. It is designed to work in
temperatures between -5C and +55C. Do not use your helmet in very hot conditions
where temperatures exceed +65C. Always store your helmet in a clean dry place out of
the direct sun and protect it from exposure to moisture or extreme heat (min/max storage
temperature is -20C ~ +70C).
Avoid unnecessary impact or compression of your helmet and never use a helmet that is
damaged. Your Servore welding helmet is a quality professional tool and careful storage
will extend the life of your investment.
7. Storage and Temperature Range
Check your helmet shell and filter on a regular basis when in normal use and after
extended periods of storage. Never use a cracked or damaged helmet as this may result
in personal injury and will void your warranty.
Please replace any worn or damaged parts as necessary.
Genuine Servo Glas replacement parts are available from your authorized Servo Glas
distributor.
8. Inspection
After removing the welding filter from the shell the shell can be cleaned using a mild
detergent and water solution. Sweat bands can be washed. A silicone based lubricant
may be used on moving parts if necessary but is not normally required. The filter may be
carefully wiped with a cloth dampened with household window cleaning solution. Please
be careful not to scratch or otherwise damage the filter cartridge with fragments of
welding spatter or other abrasive dirt. Refer to the relevant parts diagram for illustrations
regarding assembly and disassembly.
9. Cleaning

Always use good quality batteries of the correct type and be careful to
ensure they are inserted in the correct manner paying careful attention
to battery polarity.
Note
The Servo Glas 4000 uses two batteries to provide backup power. Always replace
both batteries at the same time. Batteries should be replaced either: (a) Every three
years or when the low battery warning lamp turns on (please also remove batteries and
store them separately if the helmet is to be stored for a long time.) (b) When the speed at
which the filter darkens decreases or when the density of the darkness of the screen is
reduced or uneven.
To replace the batteries, remove the filter from the retaining guide frame as explained in
6-3. You will then be able to slide out the battery cases on either side of the cartridge
and replace the batteries as shown in diagrams below.

10. Cautions
■ The Servo Glas 4000 is designed for personal eye and face
protection from harmful radiation, sparks and welding spatter
produced under normal welding conditions. Please follow good
industry and safety practices and use additional protection where
necessary.
■ Cover plates are strong and of industry standard quality but they
are breakable. The Servo Glas 4000 is a quality welding helmet
but is not designed to provide protection from severe impact such as
broken grinding wheels or debris from other broken tools, corrosive
liquids, explosions, or other extreme incidents. We recommend you
always adopt a conservative attitude towards safety and take
additional precautions as required and recommended in the relevant
safety standards relating to the operation you are undertaking.
■ The welding filter is not designed to be waterproof. Please do not
use your helmet in the rain or other inclement weather. To do so
may reduce the life of your helmet and result in damage or injury.
■ In the event that your helmet or welding filter is exposed to direct
contact with, or is submerged in water or other liquid immediately
stop using the helmet, remove the filter cartridge from the shell,
remove the batteries from the filter, inspect carefully for damage and
if necessary mop-up excess moisture with a paper towel and then
leave to dry in a warm (not hot) place out of direct sunlight. Never
place your helmet in an oven or microwave to dry. Before use
perform all normal system checks and if in any doubt contact your
Servo Glas distributor. Your Servore helmet is a precision
engineered professional protection product and must be maintained
in good condition to ensure your personal protection.
■ When working in the vicinity of other welders it is necessary to
adopt good industry standard practice and ensure a minimum
distance of 1M between workers. Failure to do so may result in injury
or malfunction of the auto darkening mechanism.
■ Please do not wear the helmet when you are not welding. In
some circumstances the auto darkening mechanism may be
unexpectedly triggered resulting in reduced vision and subsequent
injury to yourself or others.
■ Servore does not support the use of Servo Glas 4000 range of
products in combination with any other manufacturers' products. To
use parts that are not approved by Servore may void your warranty
and result in personal injury. Please use only genuine Servo Glas
4000 parts and spares as provided by your authorized Servo Glas
distributor.
■ Servore reserves the right to make improvements, change or
otherwise modify the specifications, materials and design of any and
all Servore products at their sole discretion with a view to ensuring
continuous improvement. Never attempt any unauthorized
modifications or alterations to your Servore product. To do so may
result in personal injury and void your warranty.
Thank you for purchasing a Servore product. If you have any questions regarding this
or any other Servore product please contact your authorized Servo Glas
distributor.
