PRECAUTIONS
RISK OF ELECTRICAL SHOCK
Warning! Always disconnect the fixture from AC power before and while servicing.
Removal of any cover exposes connectors that carry lethal electric currents. While working on a fixture under
power:
• Make sure the fixture is electrically grounded.
• Use a supply with ground-fault-interrupt protection.
• Never touch any connector that carries voltage.
• Be careful with tools that conduct electricity.
RISK OF UV RADIATION AND LAMP EXPLOSION
Discharge lamps emit harmful ultraviolet (UV) light that can cause eye and skin burns through direct exposure.
They also work under high pressure that occasionally causes them to explode. To eliminate the risk of injury
from the discharge lamp,
• Never operate the lamp with covers or lenses removed.
• Do not look directly into the light.
ELECTROSTATIC DISCHARGE
Printed circuit boards (PCBs), individual ICs, and Hall sensors can be damaged by electrostatic discharge
(ESD). To avoid damaging these ESD sensitive parts:
• Ensure that you and your tools have the same potential (ground) as the fixture before and when handling any of
the above components.
• Store PCBs in antistatic (electrically conducting) bags and store ICs in antistatic foam.
• Power off the fixture and allow capacitors do discharge before removing or inserting components on the PCB.
INDUCTIVE LOADS
Power off the MAC 2000 Performance before connecting or disconnecting step motors. Failure to do so can
damage the motor drivers.

SERVICE NOTES
THREADLOCK
Threadlock is highly recommended on all machine screws except self-tapping (Taptite)
screws to prevent loosening. Threadlock should be reapplied if the screws are removed.
Two types of threadlock are available from Martin. For set screws, use Loctite 290, P/N
37020002. For all other screws, use Loctite 243, P/N 37021002. Both come in 10 ml tubes.
Be careful to avoid getting any material on shafts or axles. A needle and syringe makes an
idea application tool.
Long set screws: Start the screw and turn it until it contacts the shaft. Back the screw 2
turns, apply a small drop or 2 of Loctite 290 to the threads, and then tighten the screw as
you normally would.
Short set screws: Back the set screw out of the adaptor until 2 threads stick out of the
shaft. Apply a small drop or 2 of Loctite 290 to the threads, and then tighten the screw
within 60 minutes.
Other metric screws: Apply a drop of Loctite 243 (blue) to 3 or 4 threads, or spread a thin
stripe with a syringe, before starting the screw.
SELF-TAPPING SCREWS
The reuse of self-tapping “Taptite” screws is not recommended as these screws are
designed to cut threads and can strip existing threads when reinserted. Change to metric
hardware of the same size when reinstalling parts originally held with Taptites.
If installing a new part without threads, use new self-tapping screws. Do not use old
taptites to cut new threads!
LUBRICATION
Silicone grease, P/N 37302002, “Silicon grease, clear, 100g”, is used, for example, to
lubricate brass bushings inside of pulleys and between moving metal plates such as the
motor bracket for color wheel 1 on the MAC 2000 Wash.
Slides are generally lubricated with the high viscosity silicone oil, P/N 37302005, “High
viscosity silicone oil, 200 ml, in applicator bottle.”
Bearings are lubricated with P/N 37302004, “Silicone oil, 200 ml, in applicator bottle”.
