CARE OF YOUR OPENER

When properly installed, opener will provide high performance with
a minimum of maintenance. The opener does not require additional
lubrication.
Limit and Force Settings: These settings must be checked and
properly set when opener is installed. Weather conditions may cause
some minor changes in the door operation, requiring some
re-adjustments, particularly during the first year of operation.
Refer to Setting the Limits and Force on page 12. Follow the
instructions carefully and repeat the safety reverse test after
any adjustment.
Transmitter Battery: The lithium batteries should produce power for
up to 5 years. If transmission range decreases, replace battery.
To Change Battery: To replace batteries, use the visor clip or
screwdriver blade to pry open the case. Insert batteries positive side up.
To replace cover, snap shut along both sides. Do not dispose of the old
battery with household waste. Take batteries to a proper disposal
center.
