WARNING
Only appropriately qualified personnel should carry out maintenance on Planet light fixtures
9.0 MAINTENANCE
:
Planet Lighting recommend that if there is a technical fault with one of our ULED lights, the product is returned to
our factory to be repaired. If a qualified technician is available to repair the fixture, circuit diagrams, parts lists, and
descriptions will be made available to assist in this process.
The following maintenance procedures performed as required should ensure your Planet Model ULED provides
many years of effective service
9.1 Cleaning
Carefully remove any loose deposits with a damp sponge. Use a soft brush (non abrasive) or cloth, and/or a mild
household detergent solution to remove dust and other deposits. Do not use steel wool, scrapers, scouring liquids or
powders to remove deposits as these permanently scratch the coating surface. Wipe with clean damp sponge to
remove detergent.
9.2 Head Removal (refer Fig 10)
In the unlikely event that one or more of the LED’s should fail, the light head has been designed to be removed
without tools for return to Planet lighting for prompt service. Our LED light head does not contain user seviceable parts.
9.3 Lubrication (refer Fig 9)
To prevent undue stiffness or joint seizure the springs of the Planet Model U have been pre-packed with high
quality grease. The pivoting mechanisms at the main elbow joint and the link pin at the swivel head should receive
regular light oiling.
9.4 Lock Nut Adjustment (refer Fig 9)
Fine adjustment of the frictional inertia of the lamp movement is provided by tensioning the small lock nut on the link
pin at the base of the swivel head. This nut should be tensioned so that the lamp firmly retains its position when
adjusted but can be freely re-positioned under the pressure of one finger at the elbow joint. Do not attempt to correct
an unbalanced movement by over-tightening this nut. (refer Fig 9)
WARNING UNDER NO CIRCUMSTANCES SHOULD THE SPRING TENSION NUTS (TWO) BE COMPLETELY UNDONE
.
(refer Fig 11)
9.5 Spring Tensioning (refer Fig 11)
After extended use the main balance springs of the Model ULED arm may require tension adjustment (generally the
spring on your left hand side when facing the lamp). This may be done by carefully prising the plastic cap off the end
of the spring tube to permit access to tensioning nuts. Nuts should be tightened in small increments using a 15mm
hexagon tube spanner until the lamp assumes correct balance.
Do not over tighten tension springs.
