5 Maintenance
Simple maintenance can be performed by the user to help keep the equipment operational. The following
routine maintenance is designed to prevent problems before they occur. See Section 6, Troubleshooting, for
recommendations for restoring the equipment to operation after an error condition has occurred.
Preventative maintenance is recommended after the first 250 hours of operation, and every three months or
250 hours thereafter. If the equipment environment is dirty or dusty, preventative maintenance should be
performed more frequently.

Tools Required – The recommended equipment and supplies needed to perform the functions required for
this task are described below.
Compressed air blower
Damp cloth (use water only or a mild soap diluted in
water)
To ensure adequate cooling and maximum efficiency of the
internal cooling fans, the amplifier's front and rear grills should
be cleaned periodically, and compressed air should be flushed
from front to back through the amplifier. To clean the amplifier
grills and internal heat sinks, complete the following steps:
1. Turn completely down (counter-clockwise) all level controls and turn the amplifier OFF. Disconnect
the amplifier from its power source.
2. Using a compressed air blower, force air through the front ventilation grill and the internal heat
sinks, and toward the back ventilation grills.
3. Using a damp cloth, clean the front and rear ventilation grills. Dry with a clean cloth or allow to air
dry. IMPORTANT: Grills should be completely dry before plugging in or restarting amplifier.
