H4-PREMIUM ASSEMBLY GUIDE

FIRST TIME SETUP

Follow these simple steps to get your H4-Premium High Pressure Washer ready for action.

1

Unpack and Inspect

Remove the H4-Premium machine and all accessories from the packaging box. Verify you have: Gun & Jet Nozzle, Extension Lance & Roto Nozzle, 8M Hose, Foam Bottle, Quick Connector, and the Filter & cleaning Pin.

2

Install Water Inlet Filter

Screw the water filter onto the machine's water inlet. This transparent filter acts as the first line of defense to protect the high-performance pump from sand, debris, or sediment.

Note: Hand-tighten only to prevent thread damage. Do not use wrenches or tools.
3

Connect the 8M High Pressure Hose

Connect one end of the 8M high-pressure hose to the machine's water outlet socket. Push it in firmly and screw/lock it in place to ensure a leak-proof seal.

4

Assemble Gun and Lance

Attach the extension lance to the trigger gun handle by inserting and twisting to lock. Connect the other end of the 8M high-pressure hose to the bottom inlet of the gun.

5

Connect Water Supply

Fit the Quick Connector onto your garden water hose. Connect the garden hose from your tap to the transparent water inlet filter on the machine. Turn the tap water fully ON.

6

Purge Air (Critical Step)

Do NOT switch the machine power ON yet. Squeeze and hold the gun trigger to allow water to flow freely. Keep trigger held until a constant, bubble-free stream of water flows out of the nozzle.

Crucial: Running the machine dry or with trapped air inside can cause cavitation and permanently damage the pump.
7

Power On & Clean

Plug the machine's power cord into a suitable 220V-240V socket. Toggle the machine power switch to ON. You are now ready to enjoy the powerful cleaning of your HEUGOR H4-Premium!
