13. LIGHTING TOWER MAINTENANCE
We recommend regular cleaning of the lighting tower to avoid the build up of dirt. The frequency of
the cleaning depends on the location of the lighting tower.
Any extraordinary service items not mentioned above require a specialised technician.
13.1 LUBRICATION OF THE ROLLERS
For the lubrication of the rollers, use low temperatures and extremely high speed bearing grease.
We recommend to the use of SKF LGLT 2 grease, a premium quality fully synthetic oil based
grease using lithium soap. In the event another product is used, the grease must have a base oil
viscosity equal to 18 mm²/s at 40°C and to 4,5 mm²/s at 100°C.
13.2 LUBRICATION OF MAST SECTIONS
For the lubrication of the mast sections, we recommend using light lubricating oil such as WD40.
Spray it on the metal parts of the mast, in order to avoid squeaking and scraping noises during the
raising and the lowering operations. In the event of frequent use of the lighting tower, lubricate
every three months.
13.3 LUBRICATION OF STABILISERS
Grease the stabiliser’s regularly, using a dense grease. Verify if the movement of the stabiliser is
correctly.
13.4 CHECK HYDRAULIC CYLINDER
Confirm regularly the conditions of the hydraulic pushing cylinder, ensuring there are no traces of
rubbing, leaks or corrosion.
13.5 CHECK STEEL CABLES
The steel cables are 6mm diameter composed of Carbon wires with Class B Galvanized protection
and a Polymer core with a minimum breaking load of 3294 kgs. They enable the raising and
lowering of the telescopic mast. It is recommended to inspect the cables every 250 hours service
to verify their condition and ensure their correct position inside the pulleys. It is the Manufactures
recommendation that all cables and pulleys are replaced as required. If the steel cable shows
unusual signs of wear or damage, do not use the lighting tower and contact PR Power.
13.6 CHECK OF HYDRAULIC CONNECTIONS
Check the connections for the hoses that transport the hydraulic oil from the tank to the cylinder.
Check hoses are sufficiently tightened. Check for wear and tear on the hoses. Check for oil loss.
