MAINTENANCE
If the projector’s lens becomes damaged or broken it should be replaced. If the lamp becomes
damaged or deformed in any way it must be replaced. If the light from the lamp appears dim this
would normally indicate that it is reaching the end of its life and it should be changed at once, old
lamps run to the extremity of their life can explode. If the projector does not function, check the fuses
on the power socket of the projector, they should only be replaced by fuses of the same specified
value 6.3A/250V (fast blow, 5mmx20mm). On the main PCB inside the projector there is also a fuse
rated 4A/250V (fast blow, 5mmx20mm). Should these be damaged call a qualified technician before
replacement. The projector has 2 thermal protection devices that will switch off the projector in case of
overheating, should either of these operate, check that the fans are not blocked, and if they are dirty
clean them before switching on the projector again. Check that the fans are operational, if not call a
qualified technician.
Any maintenance work should only be carried out by qualified technicians.
CHANGING THE GOBOS
LAMP ACCESS HATCH
(THE TEXT IS UPSIDE DOWN)
GOBO
RETAINING SPRING
Carefully lift off the plastic cover by undoing the 4 M4 screws. (NOTE: The projector has two covers
with the same shape. The cover removed must be right one, so you can change the gobos easily. How
to remove the correct cover, the easy way is to position the projector with the text of the lamp access
hatch upside down as shown above, and then remove the upper cover.)
Using a small screwdriver remove the gobo retaining spring.
Insert the new gobo into position, and then insert the retaining spring.
Mount the cover again and retighten the 4 M4 screws.
NOTE: It is recommended to add a little adhesive, such as high temperature silicon sealant, to hold
securely the retaining spring inside the gear.
LUBRIFICATION
pilot300_en.doc 8/14
To ensure the continued smooth rotation of the rotating gobos it is recommended that the wheel is
lubricated periodically, preferably every two months. Use only high working temperature low viscosity
oil, a syringe with a fine needle is the easiest way to introduce the oil to the bearings around each
gobo. Do not over lubricate as this will cause spillage when the wheel rotates.
