What is the correct way to set the timer on a lasko tower heater manual?

<span style="font-size: 10pt; font-family: Arial;" data-sheets-root="1">My garage workshop gets freezing in the winter, and I pulled out my Lasko tower heater but the remote control was missing and I couldn't figure out how to set the oscillation feature without it. The buttons on the unit weren't clearly labeled. Rather than buying a new heater, I looked for the instructions online. It turns out you can find all the operating instructions, including how to use the manual controls and clean the filter, by checking the lasko tower heater manual available at https://lasko.manymanuals.com/ It explained the button combination to lock the controls so my kids wouldn't accidentally turn it on.</span>

Thanks a lot for pointing me to the lasko tower heater manual, I finally figured out how to set the timer for the night.
