I'm getting an E1 error. I need to get the Lube and Walk kit, but I can't make the tread rotate. Is there another problem? I turn the machine off and then turn it on, but when I hit the "Quick" button, the E1 error appears. Even if I lube it, how will it rotate if the belt isn't moving?

You have to check the Speed sensor of the tread. IF the speed senor is faulty this problem can occur. Normally in all treadmills E1 denotes the speed sensor error.

You have to disconnect the power supply for more than 30 sec

You have to check the Speed sensor and its position.Normally you will find the speed sensor near motor pulley. In almost all treadmills E1 Error is related to speed sensor.

follow this steps and fix it. See the diagram attached. God bless you
ERR 1 - Motor Movement
ERR1 indicates a speed issue. In this case, the motor speed as reported from the optic sensor differs
from the speed setting.
Analysis: Optic sensor signal issue -- Either the optic sensor signal is not right, or it is read incorrectly, or
the signal is not reaching the display.
Of course you must lube the deck belt. see the video attached.

1)you must LUBE the DECK BELT, inmediately, for to avoid the friction
2)LUBE the rollers bearing.too
3) See the main motor for bearing and repair the motor for bearint too.
4) If the problem persist you have worn deck belt, and replace.
God bless you

1) you have speed sensor error, adjust see the diagram, clean it, and tight the wires connector very well.
2) LUBE the deck belt, very well
3) lube the rollers bearing too
4) measure the input voltage motor, if there are the motor need repair.
5) measure the output voltage board, for input voltage motor,if there are not the board is faulty. see the diagram.

1) lube the deck belt.
2) lube the rollers bearing
3) measure the input voltage motor, if there are the motor need repair.
4) measure the output voltage board, for input voltage motor, if there are NOT the board is faulty.
God bless you
see the block diagram

Oil change every 3000 miles

air filter inspect every 3000 miles // less if you in the country
Change every 12,000 miles

There is nothing to lube on a modern day car!

Wheel bearing inspect every 12,000 miles.

Fuel filter 24,000 miles or less

Tire rotation is depending on are you a lead foot driver.
Keep tabs on the rear treads.
The rear wear faster on RWD car.
The idea is keep the wear even.

Shop around,some shop is offering free tire rotation with oil change!

I rotate my tires every 6000 miles.
