15. LIGHTING TOWER MAINTENANCE
We suggest a frequent cleaning of the machine in order to avoid the presence of dirt which can
compromise the efficiency of the machine. The frequency of this operation tightly depends on the
place where the machine is used.
The extraordinary service operations not mentioned here above require the aid of specialized
technicians.
15.1 LUBRICATION OF THE ROLLERS
For the lubrication of the rollers, use low temperatures and extremely high speed bearing grease.
We recommend using SKF LGLT 2 grease, a premium quality fully synthetic oil based grease
using lithium soap. In case of use of an other product, the grease will must have a base oil
viscosity equal to 18 mm²/s at 40°C and to 4,5 mm²/s at 100°C.
15.2 LUBRICATION OF MAST SECTIONS
For the lubrication of the mast sections, we recommend to use a light lubricating oil like WD40.
Spray it on the metal parts of the mast, in order to avoid squeaking and scrapping noises during
the raising and the lowering operations. In case of frequent use, lubricate every three months.
15.3 LUBRICATION OF STABILIZERS
Grease periodically the stabilizer using a dense grease adapted to sliding system sto apply
through the apposite tool to insert in the valves placed on the stabilizer (if previewed). Verify if the
movement of the stabilizer is correctly.
15.4 CHECK OF HYDRAULIC CYLINDER
Verify periodically the conditions of the hydraulic pushing cylinder, controlling that there are not
any usury traces, rubbing, leaks or corrosion.
15.5 CHECK OF 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.
15.6 CHECK OF HYDRAULIC CONNECTIONS
Verify periodically connections and hoses that transport the hydraulic oil from the tank to the
cylinder, check the tightening of the hoses, verify eventual usury signs or cuts. Verify if there is a
oil’s loss.
