When conducting an annual service on a wheeled vehicle, do you also have to do the biannual and semi?

Read the TM- it is laid out, in doubt contact your Motor SGT.

If you have no records of services for that piece of equipment then you conduct the hugest lever of service AR 750-8 can help you out. If you have a record of a semi annual service as the last service then no you do not.

If they weren't done previously.

Do a semi with an annual. It should be a separate maintenance plan. Also, if you have enrolled your equipment into LUP, you would perform the highest service first. Take out the biannual annual and semi, take out the semi annuals. Perform quarterlies in place of semi annuals IAW AR 750-1. Why wouldn't you want to perform all lower services when the higher services are due? The bottom line is to synchronize your maintenance plan intervals to how you perform the services.

PFC (Join to see) As mentioned by SGT David A. 'Cowboy' Groth, yes, if they were not done per the vehicle's scheduled maintenance. If the maintenance was not done, per the schedule, why was it not done?

If you are doing an annual service you should have paperwork that states when your services need to be done everybody who is comment ing on this is correct but are you doing this as an operator or 20 level maintenance that would make a difference

I would perform a semi- annual service since it is close to the annual.

You work from the top down. So with an annual, you would only do semi.

semi is done as part of annual. Annual and semi are done as part of Bi-annual
