1 Important safety instructions
WARNING
• Do not use any unsafe work techniques.
• No changes to the mechanical, electrical or thermal safety de-
vices must be made.
• This appliance is not to be used by children or persons with re-
duced physical, sensory or mental capabilities, or lack of experi-
ence and knowledge, unless they have been given supervision or
instruction.
• This machine shall only be used with cleaning chemicals sup-
plied or recommended by your dealer. The use of other cleaning
chemicals may adversely affect the safety of the machine.
• Risk of explosion – Do not use the cleaner to spray with flamma-
ble liquids.

CAUTION
• High pressure jets can be dangerous. Never direct the water jet
at persons, pets, live electrical equipment or the machine itself.
• Never try to clean clothes or footwear on yourself or other per-
sons.
• The operator and anyone in the immediate vicinity of the site of
cleaning should take action to protect themselves from being
struck by debris dislodged during operation.
• Wear goggles during operation.
• Do not cover the machine during operation.
• Never use the machine in an environment where there could be a
danger of explosion. If any doubt arises, please contact the local
authorities.
• It is not allowed to clean asbestos-containing surfaces with high
pressure.
• This high pressure washer must not be used at temperatures
below 0°C.
• Only use correct fuel as specified. Improper fuels can cause se-
vere hazard.
• During operation of the cleaner, recoil forces are produced at the
gunvalve and spray lance and, when the spray lance is held at an
angle, a torque is also created. The gunvalve and spray lance-
must therefore be held firmly in both hands.
• Check that cleaning will not result in dangerous substances (e.g.
asbestos, oil) being washed off the object to be cleaned and
harming the environment.
• Do not clean delicate parts made of rubber, fabric, etc. with the 0°
jet. Keep some distance between high pressure nozzle and sur-
face in order to prevent the surface from damage.
• Never operate the cleaner without water. Even brief shortages of
water result in severe damage to the pump seals.
• Do not use any unsafe work techniques.
• Do not tie the trigger handle open.

Instructions for use Prior to using the appliance for the first time, be sure to read this docu-
ment through and keep it ready to hand.
Besides the operating instructions and the binding accident prevention
regulations valid in the country of use, observe recognised regulations
for safety and proper use.
Purpose and intended use This high-pressure cleaner has been designed for professional use. It
can be used for cleaning agricultural and construction equipment, sta-
bles, vehicles, rusty surfaces, etc.
The cleaner has not been approved for cleaning surfaces which comes
into contact with food.
Any other use is considered as improper use. The manufacturer ac-
cepts no liability for any damage resulting from such use. The risk for
such use is borne solely by the user. Proper use also includes proper
operation, servicing and repairs as specified by the manufacturer.
Further support
Before use
For further queries, please contact the GRACO service representative
responsible for your country.
Before starting up your machine, please check it carefully for any de-
fects. If you find any, do not start up your machine.

3 Before starting the cleaner
Fill up detergent tank1) 1. Fill up detergent tank with
prediluted detergent.
2. Pull detergent filter out of the
storage and put it through the
opening of the detergent tank
filler cap.
1. Before using the cleaner for
the first time, check it care-
fully to detect any faults or
damage.
2. In the event of any damage
contact your GRACO dealer
immediately.
3. Check the oil level by lifting
off the cap. On level ground,
the oil should be just visible.

coupling
Maintenance
1. Mount a male coupling on the water tap.
2. Connect (a) on the BA valve to the water tap.
3. Mount a female coupling on the water inlet hose.
4. Connect (b) on the BA valve to the water inlet hose.
5. Connect the water inlet hose to the high pressure washer.
6. Turn on the water and start the machine.
At least once a year, check the function as follows:
1. After work, switch off the high pressure cleaner.
2. Close the water tap valve.
3. Release the pressure in water the supply hose by triggering the
spray pistol.
4. Dismount the backflow preventer. Water has to come out of the
drain opening (c) (max. 100ml) to ensure separation of the potable
water.
5. If this is not the case, try cleaning the BA valve or contact your
GRACO representative.
CAUTION
• The backflow preventer can be mounted either vertically or hori-
zontally, and the drain opening (c) must be mounted pointing
downwards.
• Water flowing from the drain opening (c) must be able to flow
freely.
• If there is a risk of running sands in the inlet water (i.e. from your
own well), an additional filter should be mounted between the
water tap and backflow preventer.
• The length of the hose between the backflow preventer and the
high pressure washer must be at least 12 metres (min diameter
3/4 inch) to absorb possible pressure peaks.
• As soon as water has flown through the BA valve, this water is
not considered to be drinking water any more.
• Protect the backflow preventer to any exposure to frost.
• Keep the backflow preventer clean, and free of dirt.
This high pressure washer/cleaner is only allowed to be con-
nected with the drinking water mains, when an appropriate
backflow preventer has been installed, Type BA according to
EN 1717.
The BA valve can be ordered under number:
• BA valve including GARDENA couplings: 106411177
• BA valve including NITO couplings: 106411178
• BA valve including GEKA couplings: 106411179
• BA valve without couplings: 106411184
The couplings can be ordered under number:
• 3/4” GARDENA (a): 32541
• 3/4” GARDENA (b): 1608629
• 3/4” NITO (a): 1602945
• 3/4” NITO (b): 1600659
• 1/2” NITO (b): 1604669
• 3/4” GEKA (a): 1718
• 3/4” GEKA (b): 1311

Connecting the water supply 1. Rinse the water supply hose
briefly in order to prevent
sand an other dirt particles
entering into the machine.
2. Connect water supply hose to
the machine.
3. Open water tap.
Electrical connection Before connecting devices with voltage changeover1): Check that the
pre-selected voltage on the machine corresponds with the voltage of
the electrical installation.
CAUTION
• In the case of poor water quality (sand, etc.), we recommend that
a fine water filter is fitted in the water inlet.
• We recommend the use of a textile-reinforced water hose with a
nominal diameter of min. 3/4” (19 mm).
CAUTION
• Only connect the machine to an installation with earth connection.
• The electric installation shall be made by a certified electrician.
• According to IEC 60364-1 it is strongly recommended that the
electric supply to this machine should include a residual current
device (GFCI).
• Do not damage the power cord (e.g. by driving over it, pulling or
crushing it).
• Disconnect the power cord by grasping the plug only (do not pull
or tug the power cord).
CAUTION
• When using cable reels: Due to the risk of overheating and fire,
always unwind the power supply cord fully.
• Cable connections should be kept dry and off the ground.
Extension lead As an extension lead, only use the version specified by the manufac-
turer or one of a higher quality.
When using an extension lead, check the minimum cross-sections of
the cable:
Cable length Cross section
< 16 A < 25 A
up to 20 m 1.5 mm22.5 mm2
20 to 50 m 2.5 mm24.0 mm2
