Terms of Use

In order for the mini-sink to last as long as possible, it is necessary to observe not very complicated rules for the safe operation of the device specified in the instructions for use:

• Remember to ensure that there is sufficient water in the sink. If this rule is neglected, the pump can quickly fail.
• Take care that the hose does not bend. Otherwise, the device will fail due to exceeding the water level. It will not be superfluous to ensure that you do not step on the hose or move it with the appliance wheel.
• Select a mini-sink so that it is equipped with a hose reel. The working life of the device will be much longer.
• Do not forget to drain the water after the operation of the device is completed. Especially if you operated the sink at a low temperature. Water, turning into ice, will provoke a breakdown of the device.

Important! It is equally important to release pressure from the pump.

• Use the mini-sink very carefully. Water is supplied at high pressure, so if used carelessly, even small dents may appear on the surface of the car. Therefore, it is not necessary to bring the device to the work surface too close.

Important! It is strictly forbidden to direct the device at people or animals, as this may cause injury.

• If you need to take a short break from work, in no case do not leave the device turned on.
• Make sure that there is no foreign matter in the water used.
• Change the oil in time.

Frequent breakdowns

The given preventive measures will protect working and others. But this does not mean that the sink will work forever. Even with the most accurate operation, damage cannot be avoided. Consider the rules for the repair of a failed Karcher car wash.

Most often, over time, bearings fail, which serve as a support for the washer acting on the valve.

Symptoms of bearing failure are as follows:

1. Unstable washing operation. In this case, the engine often does not start, a knock is heard inside the device.
2. It also happens that the engine does not start at all, heats up very much when turned on.

Do-it-yourself mini-pressure washer repair is a combination of the following procedures:

• Remove the hose from the device along with the “gun”.
• Disassemble the housing, remove the motor.
• Unscrew 6 self-tapping screws located with an asterisk from the motor.
• Open the unit with the switch, remove the capacitor and the supply terminals that go from the switch.

Important! Carefully watch that the details are not lost: you will not be able to purchase something similar in the store.

• Carefully place the sink on a horizontal surface with the motor facing down.
• Prepare a container for draining the oil.
• Turn off bolts on 13 (in total 4).
• Drain the oil into the prepared container, set the rubber seal aside.
• Unscrew the bolt located in the center, having previously clamped the shaft with a key on the other side.
• Replace a worn bearing.
• Reassemble the mini-sink in the reverse order, remember to add new oil.

Important! It is difficult to select the original oil, so use a suitable analogue.

Other malfunctions

In addition to the failure of bearings, such failures also occur:

1. Pressure reduction. The performance of the device decreases, the time to complete washing procedures increases sharply. The cause of this trouble is damage to the seals. The seals fail due to the prolonged use of the sink and the presence of impurities in the water. You can solve the problem by replacing the seals.
2. Valve malfunction. It’s unlikely that you can fix it yourself, so it’s much wiser to contact a service center.
