Kılavuzda belirtildiği üzere sibop bisiklet pompasıyla kontrol edildi.

Kılavuz means guide or manual. The ending -da is the locative suffix, which often means in, on, or at.

So:

• kılavuz = manual / guide
• kılavuzda = in the manual / in the guide

In this sentence, it introduces the source of the instruction: in the manual.

This is a very common kind of formal Turkish expression, and it can look intimidating at first.

It breaks down like this:

• belirt- = to state, indicate, specify
• -il- = passive
• -diğ- = part of the -DIK verbal noun/participle structure
• -i = third-person possessive ending
• üzere = as, in accordance with, in the manner stated

So belirtildiği üzere means something like:

• as stated
• as indicated
• as specified

The whole phrase kılavuzda belirtildiği üzere means as stated in the manual.

The passive is used because the sentence focuses on what was stated, not on who stated it.

Compare:

• Kılavuzda bir şey belirtildi. = Something was stated in the manual.
• A more active version would need an agent, but here that is unimportant.

This is very natural in formal or technical Turkish, especially in instructions, reports, and manuals.

That ending comes from the Turkish -DIK nominalizing/participle structure, which is used to turn a clause into something like what is/was ..., the thing that ..., or that ... was ... depending on context.

Here, belirtildiği is part of a set phrase:

• belirtildiği üzere = as it is stated / as stated

You do not need to translate it word-for-word every time. It is often best to learn the whole chunk as a formal expression.

Other similar examples:

• söylendiği gibi = as said
• görüldüğü üzere = as can be seen / as seen
• anlaşıldığı üzere = as understood / as is understood

In this sentence, üzere means something like:

• as
• in accordance with
• as stated
• according to

So:

• kılavuzda belirtildiği üzere = as stated in the manual

Be careful: üzere can have other uses in Turkish too, such as expressing purpose or something about to happen, but in this sentence it belongs to a formal expression meaning as stated/according to.

Sibop means valve.

It is a technical word, often used for things like:

• tire valves
• pump valves
• engine valves

In this sentence, it is the thing being checked.

Because bisiklet pompası is a noun compound meaning bicycle pump.

Turkish often forms compounds like this:

• bisiklet = bicycle
• pompa = pump
• bisiklet pompası = bicycle pump

That final -sı is a normal part of this kind of compound.

Then Turkish adds -yla / -yle meaning with / by means of:

• bisiklet pompası + ile
• this becomes bisiklet pompasıyla

So bisiklet pompasıyla means with a bicycle pump.

İle means with. In Turkish, it often attaches to the previous word as a suffix-like form:

• araba ile → arabayla
• kalem ile → kalemle
• bisiklet pompası ile → bisiklet pompasıyla

Because pompası ends in a vowel, Turkish inserts a buffer y:

• pompası + ile → pompasıyla

So both of these are possible in principle:

• bisiklet pompası ile
• bisiklet pompasıyla

The attached version is very common and natural.

It is the passive past tense of kontrol etmek:

• kontrol etmek = to check / inspect / test
• kontrol edildi = it was checked

Breakdown:

• kontrol et- = check
• -il- = passive
• -di = past tense

So the sentence does not say who checked the valve; it simply says that the valve was checked.

Because this kind of sentence is written in a formal, technical, impersonal style.

The focus is on:

1. what the manual says
2. what procedure was carried out

—not on the people doing the actions.

This is extremely common in Turkish technical writing, manuals, and reports.

English often does the same:

• As stated in the manual, the valve was checked with a bicycle pump.

Turkish word order is flexible, but the most neutral order often puts background information first and the verb at the end.

Here the order is:

• Kılavuzda belirtildiği üzere = as stated in the manual
• sibop = the valve
• bisiklet pompasıyla = with a bicycle pump
• kontrol edildi = was checked

This is very natural because:

• the introductory phrase sets the context first
• the main verb stays at the end, as usual in Turkish

A different order may still be possible, but this version sounds formal and well-structured.

Yes, that is a very good idea.

Even if you understand the grammar piece by piece, it is especially useful to learn this as a chunk:

• kılavuzda belirtildiği üzere = as stated in the manual
• yukarıda belirtildiği üzere = as stated above
• daha önce belirtildiği üzere = as stated previously

This kind of phrase appears often in formal Turkish, and memorizing it will help you read technical or official texts more comfortably.

Sometimes yes, but the tone changes.

• belirtildiği gibi = as stated / just as stated
• belirtildiği üzere = as stated / in accordance with what is stated

Both can be translated similarly, but üzere usually sounds more formal and written, especially in technical or official language.

So in this sentence, üzere fits the style very well.

Turkish has no separate word exactly like English the.

Whether sibop means a valve or the valve depends on context. In a sentence like this, especially in technical writing, it is often understood as the valve because the valve is already known from the situation.

So even without an article, Turkish can still express a definite meaning through context.

Yes. Even if the core meaning stays the same, English can phrase it in several natural ways:

• As stated in the manual, the valve was checked with a bicycle pump.
• In accordance with the manual, the valve was checked using a bicycle pump.
• As specified in the guide, the valve was tested with a bicycle pump.

That is one reason Turkish learners sometimes struggle with forms like belirtildiği üzere: the grammar is compact, but English may express it in several different ways.
