Safety Precautions:
To safeguard the operator who uses the machine and its accessories and as accident
prevention and protection of bystanders and property, the following safety precautions must
be observed. Always treat the water blaster in the same way as any other power driven high
speed cutting tool!
Never let children or people who have not been properly instructed operate the machine.
Use the electric plug in a proper socket with ground to earth wiring. The entire electrical
installation must be with earth wiring! All electrical installations must be made only by an
electrician. A GFCI (Residual current device) is recommended.
Always keep the high-pressure cleaner and the belonging accessories in good working
condition. Check that the machine and its accessories are free from defects, and in good
working condition, with special attention to the insulation on the electric cable. In case of
defect: Do NOT OPERATE THE MACHINE! Get the machine serviced.
Eye protection must be worn at all times when operating the machine to protect against
repelling or ricocheting materials hitting the eyes and causing damage.
Ear protection must be worn at all times when operating the machine to protect against hear
loss during operation.
Proper footwear and protective clothing must be worn at all times when using the equipment
to avoid and prevent damage to the operator.
NEVER direct the jet at yourself. Do not attempt to clean your clothes or footwear with the
machine.
Precautions must be made to keep bystanders away from the working range.
NEVER spray-jet on humans or live animals, the high pressure jet can cause severe injury.
NEVER spray at electrical equipment, or at the machine itself.
Make sure the machine is turned off and disconnected from the main power supply before
service or repair.
5
Safety Precautions:
The below shown protective clothing and devices should be worn both by personnel operating
the water blaster system and equipment and by those working nearby:
Operators must wear visors or goggles to guard against spray
and flying debris. A combination of both goggles and visor is
recommended. It will protect the eyes and the face during both
water-blasting as well as abrasive water-blasting.
Safety helmets must be worn at all time by personnel within
the work area.
Helmet material must be able to withstand mechanical shock
exceeding 10G in 8ms without fracturing.
Shear proof gloves must be worn by the operator at all times.
A glove combination of a cloth inner lining and a water tight
outer layer is preferable.
Safety boots with steel toecaps minimum 0.5mm (0.02”) thick
must be worn. The toecap must cover at least 30% of the
footwear length. Basic safety footwear must also be equipped
with metatarsal guards to protect the instep. Safety boots are
available in numerous designs.
Operators and other personnel exposed to noise levels of more
than 90-dBa for more than 1 hour must wear suitable ear
protection. Ear plugs or ear muffs are usually sufficient.
Waterproof clothes protect the operator only from spray and
flying debris. They do NOT deflect direct jet impact.
Therefore, an operator must take care never to point a waterjet either at them selves or other personnel.
6
Medical emergency information:
Immediate medical attention should be given to personnel who sustain equipment related
injuries while operating the system. In such cases, it is vital that medical personnel be
apprised of all facts relevant to such injuries. Therefore, all operating personnel should be
provided with waterproof emergency medical alert tags or cards, describing the nature of their
work and the possibility of injury inherent in the use of water jetting equipment. The below
example of a standard card can be printed out or photo copied, bend, laminated and used as
medical alert tag.
7
Preparing the machine for operation:
1) Place the machine in a safe location and secure the unit with lashing belts.
2) Water Connection.
Prepare the water supply for the blaster, by attaching a 1” hose. Connect the other end to the
Water supply from the vessel.
3) High Pressure Hose Connection
Mount the high pressure hose to the blaster by attaching the swivel of the hose to the outlet
fitting of the pump head. Please use 2 spanners / wrenches to tighten the connection.
Additional high pressure hoses supplied with the machine should be mounted now by using
the supplied nipples male-male to connect the hoses together. Please use 2 spanners /
wrenches to tighten the connection.
4) Trigger Gun Connection
Mount the trigger gun with lance to the high pressure hose. Please use 2 spanners / wrenches
to tighten the connection. Mount the correct nozzle at the end of the lance.
5) Machine is now ready for operation.
Operation of the Machine:
A) Ensure that the water supply is open.
B) Turn START key – machine starts.
Allow the machine to idle a few minutes.
C) Get a firm grip with both hands on the trigger gun handle and lance handle. Press the
trigger and start blasting. Always be aware of other crew members in your working area –
Safety is first priority.
Note: Do NOT let the machine run idle for more than 10 minutes, as it may cause damage to
the pump. (Water heats up).
Shut-down of the Machine:
A) Turn the key to STOP position – machine stops.
B) Squeeze the trigger gun to release the pressure inside the high pressure hose.
C) Turn off the water supply.
Storage of machine during Winter time.
Store the machine in a frost free location.
Drain the water from the machine and flush the pump with anti-freeze fluid.
The machine is usually equipped with the following safety devices:
a) Emergency Stop button stops the machine when pushed in.
b) Key starter shut down the unit when turned to 0.
c) Shut down for low oil pressure, high engine temperature and over speed.
d) Safety valve. The safety valve built onto the top of the pump is protecting against overpressure.

Check
Daily
Inspection
Set-Up & Use:
Task
Check the strainer.
Clean if necessary.
Check the oil level on the crankcase of the pump, gearbox and engine.
Fill up if necessary.
Check high pressure connections for leakage.
NEVER tighten connections under pressure.
Check high pressure hoses for wear and cracks.
Replace if necessary.
Check the air intake grill of the engine radiator.
Clean for dust if necessary.
Notice: To prevent damage to hoses, avoid letting the high-pressure
hoses rub against sharp edges for example manholes or getting
squeezed in door openings etc. Replace if necessary.
Inlet water temperature must be below 60°C (140°F)

Maintenance:
Task
Oil renewal on the pump crankcase and gear box is to be completed
the first time after no more than 50 hours of use. Oil renewal is
hereafter to be completed in every 400 hours of use. Or at least one
time a year.
For Pump and Engine use a SAE 30 or10W40 Oil (part number:83600870)
Quantity: 1,04 Liter for pump.
Fill up until the oil level is visible in the sight glass.
Oil renewal for the engine to be completed after 100 hours of use. Oil
renewal is hereafter to be completed in every 400 hours of use. Or at
least one time a year.
Switch off the machine. Loosen the oil drain screw on the lower back
of the pump crank-case. Let the oil drain out into a waste oil-tray.
Remount the oil drain screw and pour in new oil through the oil inlet
on top of the pump until visible in the oil sight glass.
Notice: Always dispose of the used oil in a proper manner.
A part of keeping the machine and its accessories in good working
condition is keeping it clean. But NEVER clean the machine itself with
high-pressure. Do not use solvents.
Keep the unit frost free, or flush the pump thoroughly with non
alcoholic antifreeze fluid.
