operations are locked until the Safety Key is put back into the console
Oil Reminder Function: Every 100 miles, in standby or shutdown state, the
word OIL will flash three times in the Time Window with three beeps. It will
repeat this reminder three times when you turn on the treadmill. After three
reminders the message will stop displaying. When the treadmill reaches 200
miles the reminder will appear again.
To maintain the longevity of your treadmill it is highly recommended that you
lube every 40 usage hours or 3 months, whatever comes first. Over time the
lubricant will dry out regardless of whether the treadmill is used or not. Lubing
will help increase the longevity of your motor and belt. This will help extend the
life of your treadmill and keep you on track to reach your goals.
Window Light Colors: When the treadmill runs the light will be green. When the
treadmill is in standby state the light will be red. When the safety key is removed
the light turns to yellow.
