FIX WALL BASE
Chosen a location for your pressure hose reel, follow the figure 1 of the wall base
template to mark the location of 4 holes for drilling, or place the wall base itself up to
the wall to mark the location of the screw holes for drilling.
1.
Note: Please install the machine at a height of approximately 24-32in above the
ground to maximize the function of auto-retract.
13
Use a 12mm diameter drill bit to drill the 4 marked holes. Hole depth is important.
You may choose to measure a 2.6in depth on the drill bit itself and mark it with a
small piece of tape so you know when you’ve drilled the appropriate depth into the
wall. Using a correctly sized drill bit will ensure a secure installation of the wall base. To
make sure the wall anchors have a secure t, you may choose to drill a slightly smaller
hole rst, then size up if it proves too small for the wall anchor.
Hammer the wall anchors into the 4 drilled holes.
Place the base to the wall, aligning the wall anchors with the designated holes in the
wall base. Screw in the screws with either a socket set or a Phillips screwdriver.

washer by hand and tighten it by hand (Please make sure that there is no debris
blockage on the lter side of the water inlet hose) (Fig. 7).
4.
Fig. 7
CAUTION: Please do not use tools such as a wrench to tighten it. That will damage
the machine.
Turn the water supply on, making sure that the tap is fully open. Release the trigger lock.5.
CAUTION: We recommend keeping the inlet water pressure less than 0.8MPa
(116 PSI) during the use of the pressure washer to prevent the machine from not
working or the inlet hose from blowing up during usage.
Trigger the gun to expel the air in the unit before it's working.
Turn the ON/OFF switch to the “OFF” position.
Put the plug into the socket of the main electric power.

Step 1: Preparation
1.1
Turn off the water faucet and turn off the power switch.
1.2
Trigger the gun to release pressure inside the item.
1.3
Disconnect the high pressure hose and the high pressure gun, and place the
pressure gun in the storage of the pressure washer.
REPLACE HIGH PRESSURE HOSES
Step 2: Pull Out the High Pressure Hose
2.1 Pull out the entire high-pressure hoses.
2.2 Use the hub pin to hold the reel, refer to arrow 2.2.
2.3 Use a suitable screwdriver to remove the pressure hose hoop, refer to arrow 2.3.
17
Step 3: Replace the High Pressure Hose
3.1 Use two wrenches to disconnect the high pressure hose in the opposite direction.
Refer to arrow 3.1.
3.2 Insert the new high pressure hose through the pressure hose holder.
3.3 Connect the new high-pressure hose to the shorter pipe tting of the machine.
3.4 Use a screwdriver to tighten the pressure hose hoop. Pull out the hub pin, and pull
the high pressure hose by hand to make it retract slowly, and the replacement of
high pressure hose is completed.
Note: DO NOT directly let the high pressure hose automatically retract, the huge
retraction shock will damage to the machine and make it useless.

retracting
function will be greatly affected. Please press the handle rst to release pressure and
drain the excess water. Figure A for your reference.
Third, after releasing the pressure, please hold the pressure gun and pull the pressure hose a
little out, and then, retract the pressure hose to the whole reel. Figure B for your Reference.
Last, store your pressure gun.
Winterizing + Long-Term
Switch to the state of “OFF”.
Turn off the water supply tap.
