Narrative:

I had just gotten done with my previous task when I needed something else to do around XA00. I looked at [mechanics app] to see that the horizontal stabilizer gearbox lube needed to be complied with. So I went and grabbed a scissor lift and all my tools and consumables. I recently learned that the spanner tool that we use to remove the grease port sealing cap is not considered to be a tool but it's considered to be a part. I had to ask the stores clerk multiple times before I was able to obtain the tool. I serviced the hsta gearbox in accordance with crj 900 amm (aircraft maintenance manual) task 12-xx-xx-XXX-XXX-XXX. I used the horizontal stab trim switch to rotate the gearbox; but I did not manually rotate the input shaft like the task says to do. My thought process was that I would just rotate the gearbox by cycling the horizontal stab all the way up and down 3 times instead of manually rotating the gearbox clockwise and counterclockwise with the hex socket and it would save me some time. My common sense tells me that this would rotate the equipment inside the gearbox so that I wouldn't have to rotate it manually. In order to spread the grease around thoroughly; I cycled the horizontal stab up and down 3 times to satisfy the amm requirements of procedure 6 in the amm task 12-xx-xx-XXX-XXX. I hadn't suspected that I had done anything wrong until the next night on shift when I was approached by my inspector.insufficient training.I am still asking the question how this could be a safety violation and would appreciate some extra clarification or training on the subject.have the brand new employees do more than just 3 days and rons for the first 6 months. Have them do big jobs like this one where they can be more challenged and doing something new when they are with a maintenance training instructor. Psa already does this however; and the new sign behinds are getting on really big jobs early on. Has to do with the new employees level of experience.
