yòng xǐyījī qián, qǐng kànkan xǐdíbiāoqiān, kǒudai hé lāliàn.

Here 前 means before, and it comes after the action phrase it relates to.

So:

• 用洗衣机 = use the washing machine
• 前 = before

Together, 用洗衣机前 means before using the washing machine.

This is a very common Chinese pattern:

• V + 前 = before doing something
• V + 后 = after doing something

Examples:

• 吃饭前 = before eating
• 睡觉前 = before sleeping
• 出门前 = before going out

So the sentence begins with a time phrase: Before using the washing machine, please...

You often can add 在, but it is not necessary here.

Both of these are understandable:

• 用洗衣机前，请看看……
• 在用洗衣机前，请看看……

The version without 在 is concise and very natural in instructions, notices, and manuals.

You may also see a slightly more formal version:

• 使用洗衣机前，请查看洗涤标签、口袋和拉链。

So:

• 用洗衣机前 = natural, simple
• 在用洗衣机前 = also possible
• 使用洗衣机前 = more formal/written

用 and 使用 both mean to use, but they differ in style.

• 用 = everyday, short, common in speech
• 使用 = more formal, more common in instructions, manuals, official writing

So:

• 用洗衣机前 = before using the washing machine
• 使用洗衣机前 = before using the washing machine

The meaning is basically the same, but 使用 sounds a bit more formal and polished.

Yes, 请 often means please, but in Chinese it does a bit more than just add politeness. It often introduces a polite request or instruction.

Here:

• 请看看…… = please check / please have a look at...

In notices and instructions, 请 is very common. It softens the command.

Compare:

• 看看洗涤标签。 = Check the care label.
• 请看看洗涤标签。 = Please check the care label.

So it makes the instruction more polite and natural.

看看 is a reduplicated verb. In Mandarin, repeating a verb often makes the action sound:

• lighter
• less forceful
• more casual
• like have a quick look

So:

• 看 = look / read / watch
• 看看 = take a look / have a look

In this sentence, 请看看 sounds softer and more natural than a blunt 请看.

Compare:

• 请看标签。 = Please look at the label.
• 请看看标签。 = Please take a look at the label.

The reduplication doesn’t always mean the action is literally short, but it often gives that feeling.

Yes. All of these can work, but they have different tones.

• 看看 = take a look; everyday and softer
• 查看 = check/look over; fairly neutral, common in written instructions
• 检查 = inspect/check carefully; stronger and more deliberate

Examples:

• 请看看洗涤标签、口袋和拉链。
• 请查看洗涤标签、口袋和拉链。
• 请检查洗涤标签、口袋和拉链。

Nuance:

• 看看 sounds friendly and natural
• 查看 sounds a bit more written/formal
• 检查 emphasizes careful checking

For a laundry instruction, all are possible, but 看看 is less stiff.

洗涤标签 means the washing/care label on clothing.

Breakdown:

• 洗涤 = washing / laundering
• 标签 = label / tag

So 洗涤标签 is specifically the label that tells you how to wash the item.

If you only say 标签, that just means label/tag in a general sense. It could be any label, not specifically the laundry care label.

You may also hear:

• 洗衣标签 = washing label
• 护理标签 = care label

All are possible, but 洗涤标签 is a clear and fairly standard expression.

Grammatically, they are just more items in the list of things you should check.

The sentence is telling you to look at:

• 洗涤标签 = the care label
• 口袋 = the pockets
• 拉链 = the zipper(s)

The idea is practical:

• check the care label for washing instructions
• check the pockets so nothing is left inside
• check the zippers so they are in the right state before washing

So there is no special grammar here beyond listing multiple nouns after 看看.

Chinese nouns usually do not change form for singular vs. plural.

So:

• 口袋 can mean pocket or pockets
• 拉链 can mean zipper or zippers

The exact number is understood from context.

This is very normal in Chinese. Unlike English, Chinese usually does not require you to mark plural on nouns unless you specifically want to emphasize number.

If needed, Chinese can add a number or other wording:

• 一个口袋 = one pocket
• 几个口袋 = several pockets

But in a general instruction, the plain noun is enough.

Chinese does not have articles like a, an, and the in the same way English does.

So Chinese often just uses the noun directly:

• 洗涤标签 = the care label / a care label
• 口袋 = the pocket(s)
• 拉链 = the zipper(s)

The exact meaning is supplied by context.

Also, Chinese often leaves out possessive words like your when they are obvious. In this sentence, it is naturally understood that we mean the clothes’ label, pockets, and zippers.

A more explicit version could say:

• 请看看衣服的洗涤标签、口袋和拉链。
  = Please check the clothing’s care label, pockets, and zippers.

But the shorter version is perfectly natural.

The symbol 、 is the Chinese list separator. It is used somewhat like commas in a list.

So:

• 洗涤标签、口袋和拉链

means:

• care label, pockets, and zippers

A common pattern is:

• A、B和C

This is very much like English A, B, and C.

So in the sentence:

• 洗涤标签、口袋和拉链

the 、 separates earlier list items, and 和 joins the last one.

That is a very common way to list things in Chinese.

Pattern:

• A、B和C
• A、B、C和D

This is similar to English:

• A, B, and C
• A, B, C, and D

You do not normally repeat 和 between every item.

Less natural:

• A和B和C

That can work in some contexts, but for ordinary lists, A、B和C is much more standard.

In everyday Mandarin, 口袋 is usually pronounced kǒudai, with the second syllable in a neutral tone.

So you will often hear:

• kǒudai

rather than the full fourth tone:

• kǒudài

This is common with many two-syllable words in Chinese: the second syllable becomes lighter in natural speech.

Similarly, in 看看, the second 看 is usually neutral:

• kànkan

not equally stressed kànkàn in normal pronunciation.

Yes. 洗衣机 is very easy to break down:

• 洗 = wash
• 衣 = clothes
• 机 = machine

So literally it is a clothes-washing machine, i.e. a washing machine.

This kind of compound-building is very common in Chinese, and it is useful for vocabulary learning.

For example:

• 洗手间 = wash-hand room = bathroom/restroom
• 手机 = hand-machine = mobile phone
• 电脑 = electric-brain = computer

It is better to think of 前 here as a location/time noun or postposition-like element that comes after the phrase.

English says:

• before using the washing machine

Chinese literally builds it more like:

• use washing machine + before

So for learners, the key thing is word order:

• English: before + action
• Chinese: action + 前

That is why 用洗衣机前 may feel reversed at first.

Yes, that is a very natural English rendering.

Even though the Chinese uses 看看, which literally means have a look, in practical English this kind of instruction is often translated as:

• check
• inspect
• look at

So a natural translation would be:

• Before using the washing machine, please check the care label, pockets, and zippers.

That captures the intended meaning well.

It is not really missing; the object is understood from context.

If this appears in a laundry guide or on a sign near a washing machine, it is obvious that the sentence means the clothes/items being washed.

Chinese often leaves out information that is clear from context.

A fuller version could be:

• 用洗衣机前，请看看衣服的洗涤标签、口袋和拉链。

But the shorter version is more concise and very natural in instructions.

Yes. Here are a few possible variations:

More formal:

• 使用洗衣机前，请查看洗涤标签、口袋和拉链。
• 使用洗衣机前，请检查衣物的洗涤标签、口袋及拉链。

More everyday:

• 用洗衣机前，请先看看标签、口袋和拉链。

Notes:

• 使用 sounds more formal than 用
• 查看/检查 sound more official than 看看
• 衣物 is a slightly more formal word for clothing/items
• 及 is a formal written version of 和
• 先 adds the sense of first

So the original sentence is clear, polite, and fairly natural, especially for simple instructions.

The sentence follows a very common structure:

[Time phrase] + ， + [polite request/instruction]

Here that becomes:

• 用洗衣机前 = before using the washing machine
• 请看看洗涤标签、口袋和拉链 = please check the care label, pockets, and zippers

So the pattern is:

• [Before doing X], please do Y.

Examples of the same structure:

• 出门前，请关灯。
  Before going out, please turn off the lights.

• 睡觉前，请刷牙。
  Before going to bed, please brush your teeth.

• 吃药前，请看说明。
  Before taking medicine, please read the instructions.

This is a very useful sentence pattern to learn.
