It is read:
しゅうりいらい を だします。
Word by word:
- 修理 = しゅうり = repair
- 依頼 = いらい = request
- を = object marker particle
- 出します = だします = submit / send out / put in
So the whole sentence is pronounced:
しゅうりいらい を だします。
修理依頼 is a compound noun made from:
- 修理 = repair
- 依頼 = request
Together, 修理依頼 means a repair request.
This is very common in Japanese: two nouns are combined to make one more specific noun. So instead of saying something like request for repair with a longer structure, Japanese often just stacks nouns together.
を marks the direct object of the verb.
In this sentence, the thing being submitted is 修理依頼.
So:
- 修理依頼 = the repair request
- を出します = submit it / put it in / send it out
That is why を is used: it shows what is being acted on by 出します.
