There may be instances where you want a new PM to generate even if the previous occurrence was not completed. In Limble, this is accomplished by using the stack PMs scheduling option.

Stacking PMs is rarely needed for most maintenance tasks. However, some types of routine work benefit from this feature.

In this article, learn how to use the stack PMs feature and when we recommend applying it to your PM schedules.

How Stacking PMs Works

When you use stack PMs, the scheduler will generate a PM even if a previous occurrence is still open or incomplete.

For example, let’s imagine you schedule a weekly PM every Wednesday for a machine to get cleaned. Your technician gets pulled to deal with an emergency plumbing issue and is unable to complete the PM.

If you used the stack PM option on the weekly cleaning PM, your technician would get assigned the same PM again for the following Wednesday, even though the PM from the previous week was never completed.

If you don’t stack the weekly PM, that PM will stay open until it gets completed, and no other PMs will be generated until it’s done.

How to Stack PMs

Adding the stack PMs to your PM schedule takes a click of a button.

Go to Locations > Select Your Location > PMs. Create a PM template or add the stack PMs scheduling option to an existing PM by clicking on its calendar icon under the schedules column.

In the new pop-up, clickAdvanced Settings.”

From the new list of options, select “Stack PMs.” Then, click “Done.”

Stack PMs Example: Hourly Temperature Checks

Stacking PMs is rarely needed for routine maintenance tasks. However, there are some instances where this scheduling option comes in handy.

Stacking PMs is a great scheduling option for tasks that need to be done at a high frequency.

For example, let’s imagine you own a food production facility. Your fridges, which hold thousands of dollars worth of inventory, need to maintain a temperature between 36–38 degrees Fahrenheit to comply with food safety standards. You assign a technician to check the fridges every 2 hours to ensure the temperatures are within the safe range.

By stacking this PM, your technician will still be assigned the task of checking the fridges at hour 4, even if they missed the temperature check at hour 2.
