Lamp specifications:
• Name: single ended halide
• Base Designation: MOG(E39)

10. Hydraulic-oil unit.
• Check the hydraulic-oil unit and hydraulic oil level every 300 hours
or 3 months of work. Fill up with the same oil if necessary, always
eliminating any oil leakage that may exist.
• If the hydraulic cylinder rises unevenly or intermittently, check the
hydraulic oil level.
• Change of hydraulic oil every 2400 hours or 2 years of work or
when it loses its properties or in the case that it is contaminated by
another product.
• Each time the hydraulic oil change is performed, the lter is changed
and the tank cleaned.
• In the event that the electrovalve does not work or another problem
prevents the mast from descending automatically, this operation is
carried out by loosening the electrovalve screw. To lower the mast it is
important that the electro-valve screw is well tightened.
• Perform a revision of the hydraulic-oil unit if hydraulic oil is detected
on the ground.

8. Steel cables and pulley sets:
• Carry out periodic checks of the cables state, every 100hours or
once a month.
• When the steel cable decreases by 10% of the rated diameter due to
corrosion or abrasion, it must be replaced immediately.
• Check the cables. If a steel cable has broken, replace it as soon as
possible.
• If there is any manner of deformation (a loop, a knot or crushing),
replace the cable immediately.
• Important: always use the Steel cables indicated by the manufacturer
of the lighting tower (type 6x37 +1).
• Lubricate galvanized cables with oil when operating in high corrosion
conditions every 300hours or 3months.
9. Replacing the light bulbs and glasses.
The metal halide bulbs used in the column lights provide more powerful lighting
than ordinary halogen bulbs, for a lower consumption, with a very high service life
of approximately 8,000 hours.
Metal halide bulbs are discharge bulbs that operate using the emission of
electromagnetic rays by an ionized gas plasma. The gas is ionized using an
electric discharge (hence the name) through the gas itself.
Metal halide lamps are derived from high pressure sodium vapour lamps, with
additives (thallium, indium, dysprosium, holmium, caesium, thulium) which
improve the colour rendering of sodium lamps, giving them a very high colour
temperature (4,000-5,600 K). Their chromatic performance makes them
particularly useful when perfectly white light is required. They require special
igniters and injectors to light and these produce pulses of start-up voltage of
between 0.75 and 5 kV. During the lighting phase, it takes several minutes to
reach the maximum light output.
To replace the light bulb or glass, follow the procedure below:
• Unx the screw of the clamp (M5) with a star-shaped screwdriver and
place the clamp and the glass on a safe place.
• Replace the bulb or glass.
• Place the glass on the clamp and then both of these in the body of
the lamp. Check that the clamp has been set in place properly and
tighten the screw.
