Frequently Asked Questions - HYW4000P HYUNDAI

What type of oil should I use for the pump?

Use SAE 30 non-detergent oil for the pump. Check the oil level regularly through the sight glass and change it after every 50 hours of use.

Can I use hot water with this pressure washer?

No, this model is designed for cold water only. Using hot water can damage the pump and seals.

How do I connect the garden hose?

Attach the garden hose to the water inlet at the back of the machine. Ensure the hose is at least 12 mm (1/2 in) and tighten the connector by hand. Turn on the water supply before starting the machine.

What safety precautions should I take?

Always wear safety goggles and gloves. Never point the spray gun at people, pets, or electrical outlets. Use the trigger lock when not spraying. Disconnect power when cleaning the unit.

How do I store the pressure washer for winter?

Drain all water from the pump, hose, and wand. Add antifreeze designed for pressure washers into the inlet until it flows out of the outlet. Store in a frost-free area.

Why is the pressure washer not building pressure?

Check if the water supply is fully open and the hose has no kinks. Inspect the inlet filter and clean if clogged. Ensure the nozzle is not blocked and the pump is primed. If using an extension cord, it must be heavy-duty and short.

Can I use detergent with this washer?

Yes, apply detergent using the low-pressure nozzle (black). Fill the detergent tank with a suitable cleaner. After application, rinse with high pressure using the appropriate nozzle.

How do I change the spray nozzle?

Switch off the machine and relieve pressure by squeezing the trigger. Turn the collar on the spray wand to select the desired nozzle: 0° (red) for high-pressure, 25° (green) for general cleaning, 40° (white) for delicate surfaces, and black for detergent.

What does the thermal overload protection do?

If the motor overheats, the thermal overload switch automatically turns off the unit. Let it cool for 15 minutes, then press the reset button on the motor housing to resume operation.

Where can I find replacement parts?

Replacement parts such as nozzles, hoses, seals, and pressure regulators are available from Hyundai dealers or online stores. Use only genuine parts to ensure safety and performance.

10.3. Pump troubleshooting.

Problem	Causes	Correction
No low pressure detergent delivery	1. Using wrong nozzle2. Siphon hose or filter is plugged	1. Insert black soaper nozzle2. Unplug siphon hose
Unit does not reach required pressure	Restricted or insufficient water supply.Unsuitable or worn out nozzle.Regulator set too low.	1. Check supply hose, faucet and inlet water filter. Must be connected to water source which provides 6GPM2. Replace nozzle3. Reset unloader by turning knob (clockwise increases pressure)
Thermal Relief Valve is open and discharging water from side of pump	Water temperature is too highPump has operated more than 3 mins without pulling trigger.	Use cool water only.Pull trigger at least 30 seconds every 3 mins
Leak in the fittings	Water leak in high pressure fittings, hose or gun.	Use Teflon tape or pipe sealant to tighten hose fitting, replace hose or gun** If problem continues, take to your pressure washer dealer
Pump oil is low?	Normal use consumes oil over time	To gauge the oil level, look directly into the sight glass. Oil level should always be at the centre dot. Do not overfill. Replace SAE 15W 40 oil.
Oil is milky color	Seals have worn from use and water has leaked in	Bring unit to local service center to have seals replaced.

11. STORAGE

11.1. NOTICE You must protect your unit from freezing temperatures.

11.1.1. Failure to do so will permanently damage your pump and render your unit inoperable.
11.1.2. Freeze damage is not covered under warranty.

11.2. To protect the unit from freezing temperatures:.

11.2.1. Use Pump Saver to treat pump. This minimizes freeze damage and lubricates pistons and seals. Contact your local dealer for Pump Saver Solution.
11.2.2. If pump saver is not available, connect a 1 metre section of garden hose to
11.2.3. water inlet adapter. Pour RV-antifreeze (antifreeze without alcohol) into hose. Pull recoil handle twice. Disconnect 1 metre hose.
11.2.4. Store unit in a clean, dry area (heated area preferred).

11.3. Long term storage.

11.3.1. If you do not plan to use the pressure washer for more than 30 days, you must prepare the engine and pump for long term storage.

11.4. Protect Fuel System

11.4.1. Fuel Additive:
11.4.2. Fuel will become stale when stored over 30 days. Stale fuel causes acids and gum deposits to form in the fuel system or on essential carburetor parts. Prior to storage, if petrol has not been treated with a fuel stabilizer, it must be drained from the engine into an approved container. Then run engine until it stops from lack of fuel. When fuel stabilizers are used according to their instructions, there is no need to drain the petrol from the engine prior to

21

storage. Run the engine for a short time to circulate stabilizer throughout the fuel system. Engine and fuel can then be stored up to 24 months.

11.4.3. If petrol is drained, the use of a fuel stabilizer in the storage container is still recommended to maintain freshness.

11.5. NOTICE You must protect your unit from freezing temperatures.

11.5.1. Failure to do so will permanently damage your pump and render your unit inoperable.
11.5.2. Freeze damage is not covered under warranty.

11.6. Other storage tips.

11.6.1. DO NOT store fuel from one season to another unless it has been treated as described in Protect Fuel System.
11.6.2. Replace fuel container if it starts to rust. Rust and/or dirt in fuel can cause problems if it's used with this unit.
11.6.3. Cover unit with a suitable protective cover that does not retain moisture.
11.6.4. WARNING Storage covers can be flammable.

11.6.4.1. DO NOT place a storage cover over a hot pressure washer.

11.6.4.2. Let equipment cool for a sufficient time before placing the cover on the equipment.

11.6.5. Store unit in a clean and dry area.
