INSTRUCTIONS FOR OPERATION
Installation of Accessories
Inlet strainer must always be installed to
filter out sand, lime and other impurities
which will damage the pump valve.
1) Insert the handle into the slide cone on
top and fix it onto the body with two
pieces of 4.8 x20 cross screw. (Fig. 1)
2) Place pressure pipe hook in correct position
according to drawing and fix it onto the body
with two pieces of 3.5 X20 cross screw stud.
(Fig. 2)
3) Propel the cleaning pot into the frame in the
middle of handle according to drawing until
clamped, then plug the suction tube of cleaning
pot in to joint on the body, and make it clamped
in the groove at back of handle. (Fig. 3)
4) For initial installation of inlet nut, you should
check whether the filter is mounted into the
machine inlet by the factory or not before
tightening it into the inlet. (Fig. 4)
Connection of High Pressure Water Pipe
1) Aim the high-pressure water pipe at pikestaff valve bush and push inward to complete
the connection. Otherwise press the button and you can dismantle the high pressure water
pipe.
2) Aim the high-pressure water pipe at the machine outlet and rotate clockwise to the
-5- -6-

bottom. (Fig. 5)
Installation of Gun Barrel
1) Push gun barrel into pikestaff, which needs to be pressed down to the ground and
rotate 90 degrees to the left until the parts are completely geared and don't fall off. The
gun barrel of this machine can regulate the shape of water spray by rotating the
nozzle to the left and right.
2) When using the cleaning liquid, put it
into the cleaning pot and set the gun
nozzle to low pressure, and then start the
machine to press the trigger, it can spray
the cleaning liquid on the surface to be
cleaned. (Built-in cleaning pot) (Fig. 6)
Water Connection
•Connect to Pressurized Waterhead
The maximum inlet pressure is 0.7MPa/7bar and the highest temperature is 40℃,
refer to nameplate.
1) Ensure inlet strainer is put into inlet nut and not blocked.
2) Mount to inlet pipe with quick connector and the other end connects with
Waterhead.
•Note: according to the national and local regulations, for connection to drinking water
mains, water must flow through the pipe to prevent ingression of dirt and sand into
machine before connecting water pipe to the machine.
3) Turn off water supply, connect water intake to water inlet nut with quick connector.
•Connect to the water supply with lower pressure
The machine can also operate in self-suction mode, which means the machine can be
connected to water containers, rivers, lakes and pools, no backflow preventer is needed
when diverse from non-portable water mains. External filter must be used when connecting
the machine from water source of lower pressure to prevent suction of impurities; water
inlet pipe should be 3m in length. We recommend using original inlet pipe kit in order to
meet these requirements, and the machine is designed to pump at the maximum distance
to water level at 50cm.
1) The machine will be placed above water
level at maximum height of 0.5 meters and
separate high-pressure pipe from water outlet.
(Fig. 7)
2）Ensure the filter is in place, connected to
water inlet pipe and ensure it is tightly
connected to water inlet.
3) Turn on the machine and press the switch to
ON position.
4) Wait until steady flow from water outlet.
5) Turn off the machine and connect high
pressure water pipe and gun assembly. (Fig. 8)
Start the Pressure Washer
Warning! Before starting the cleaning operation, check whether the machine is in upright
position and placed on flat surface, do not put it in grass. The voltage and frequency of
machine (refer to nameplate) must be consistent with that of power supply.

1) Insert power plug into the power socket.
(Fig. 9)
2) Turn on the water supply, release the
trigger lock, active the handle trigger of
sprayer, and let the water out until no air
inside the pipe. (Fig. 10)
3) Turn on the machine and press the
switch to ON position. (Fig. 11)
4) Activate the trigger of pikestaff, when releasing handle trigger, the machine stops
automatically, when activate the trigger of pikestaff again, the machine starts again. It
is not allowed to quick make-and-break switch, and it should be stopped for several
seconds before restarting.
Stop the Pressure Washer
1) Cut off water supply, activate the trigger of
pikestaff, and keep the machine running until
water no longer flows from the nozzle. 2) Stop
the machine and press the switch to OFF
position.
2) Pull out machine plug from power socket, roll
up power cord and wind it to the wire rack.(Fig.
12)
3) Remove the quick connector from water inlet
nut, and dismantle the water inlet pipe.(Fig. 13)
4) Press the gun valve bush button to
dismantle the high pressure pipe. (Fig. 14)
5) Contrarotate high pressure pipe at water
outlet to dismantle the high pressure pipe
6) Put the pikestaff, gun barrel and other
accessories into bracket of pressure washer.
(Fig. 15)

MAINTENANCE AND INSPECTION
CAUTION:
Please take the following recommendations in
order to ensure long service life and no
malfunction of high-pressure washer: before
installation, clean the water inlet pipe, high
pressure pipe, gun barrel and accessories.
Clean the dust and sand on connector, and
wash the gun barrel and nozzle in order to keep
the cleanliness and smoothness of water inlet.
Cleaning the Water Inlet Filter
Depending on the situation, clean at least once
a month or more frequently clean the water inlet
filter regularly. Release the water inlet filter with
screwdriver (needle pliers) and wash it carefully.
Check the water inlet filter for damage before
reinstalling it. (Fig. 16,17)
Cleaning the Nozzle
Clogged nozzle will cause the pump pressure to
be too high. The nozzle cleaning tool (cleaning
pin) should only be used during separation of
nozzle with the machine stopped. Stop the
machine, clean the nozzle and reverse flush the
nozzle with water. (Fig. 18)
-11- -12-

Cleaning the Machine Ventilation Opening
The machine should be kept clean so that
cold air can go through ventilation
opening freely. (Fig. 19)
Lubrication of O ring
In order to ensure easy connection and
make the O ring not dry out, various types
of joints should be lubricated periodically.
(Fig. 20)
※Damaged cord must be replaced by a special cord purchased from authorized
service center.
※To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or
adjustment should be performed by authorized service centers, always using original
replacement parts.
