Operating Instructions
Congratulations on the purchase of your new Flextool product. Before attempting to
operate your machines, please read all of the instructions to ensure safe operation and
trouble free service from your pressure cleaner.
Component Checklist
The following standard accessories accompanied your machine out of the box:
1. Hose assembly
2. Gun and lance assembly
3. Manufacturers motor and pump assembly specifications
4. Detergent line with filter
Contact your point of purchase immediately if any of the above components are missing.
Pre-Operation Instructions
1. Ensure that the engine is turned off.
2. Fill fuel tank with unleaded petrol only. Do not attempt to fill the tank while the engine is
running.
3. Connect the high-pressure hose to the pump outlet.
4. Connect the other end of the high-pressure hose to the hand gun inlet.
5. Connect water supply to the inlet water fitting on the pump. Ensure that the water supply is
sufficient for the operation of the pump (minimum feed is 12lpm), if you are uncertain of the
suitability of the water supply then refer to the recommended flow rate, which is displayed on
the data plate on the pump body.
6. Ensure that the water supply hose does not have any kinks or holes, is clean and free of any
debris from being stowed or dragged along the ground.
7. Ensure that the water inlet supply filter is not blocked by foreign particles in the water supply.
Clean the water inlet supply filter regularly to ensure smooth continuous operation and
pressure delivery.
8. Turn water delivery tap to the ‘ON’ position.
9. Check that the oil levels in the pump sight glass (halfway) and engine dipstick to ensure they
are at the optimal correct level.
10. Starting engine
(i) Turn the petrol tap onto the ‘ON’ position;
(ii) (If needed e.g. cold start up) Turn the choke lever to the ‘ON’ position;
(iii) Turn ON/OFF switch on the engine to the ‘ON’ position;

(iv) Pull rope coil to start;
(v) (if applicable) Turn choke lever to the ‘OFF’ position once engine is running;
(vi) Warm engine for 30-60 seconds before operating at full operational load.
(vii) Push the throttle lever, located on the underside of the fuel tank to maximum throttle
position;
11. Gun Operation
(i) Read the safety Warning and Caution decals detailing safety precautions, PPE and
safe practice before proceeding to use the machine;
(ii) Insert desired snap-on nozzle to the end of the lance pipe for cleaning application;
(iii) Point the lance towards the surface to be cleaned and depress the trigger on the
gun;
12. Chemical Injection Operation (if desired)
(i) Insert the filter end of the clear detergent hose into the container holding the cleaning
chemical/detergent to be used and affix the opposite end to the chemical injector
barb;
(ii) Insert chemical black coloured snap nozzle; this will induce chemical injection under
a venturi effect;
13. To end operation
(i) Idle the engine down to the tortoise position;
(ii) Switch the engine to the ‘OFF’ position;
(iii) Turn the inlet water off at the tap;
(iv) Pull the trigger on the gun to release any backpressure;
(v) Disconnect both the water inlet supply hose and the water outlet high-pressure hose
at machine and gun end(s).
Important Safety Precautions
1. Do not operate without water.
2. Do not direct water jet at any part of this machine or any other electrical equipment.
3. Do not spray any person or animal or place any part of your body over the nozzle.
4. Never pull on the high pressure hose if it forms kinks, do not pull hose over sharp objects.
5. Do not attempt to disconnect either the hose or any coupling whilst there is a pressure in the
hose.
6. Do not allow machine to run unattended.
7. Switch off when not in use to avoid possible damage to high pressure pump.
8. Never supply any liquid other than water to inlet.

9. Do not attempt any mechanical repairs, if you have a problem with your machine, contact
your local service agent.
10. Ensure the appropriate PPE is worn at all times e.g. head, eye, body, hand, foot, hearing
and respiratory protection.
11. Check working area for risk of non-authorised personnel.
12. Ensure machine is secured during operation.
13. Keep clear of high temperature parts to avoid risk of burns.
14. Check machine weight before lifting. Do not attempt to lift a machine weighing more than 23
kilos without assistance.
15. Avoid leaving high pressure hose on the ground.
16. After use, pull the trigger gun to release and back pressure.
Tips and Hints
1. Regularly check the oil level in the pump. The oil level should be maintained at the level
indicated on the pump (half way on the sight glass).
2. Top up the oil in the pump when required using SAE 20W 50 oil. Never mix different grades
of oil.
3. Use a good quality 13mm (inside diameter) water supply hose and connect to the water inlet
on the pump using a hose clamp or garden style snap-on connection. Ensure that this
connection is tight and o rings and rubber tap washers are present to avoid leaks and
cavitation in pressure as pump is sucking air.
4. Do not use any water supply hotter than 60° Celsius as this will damage the internal workings
of the pump up to and including valves, seals etc.
5. Ensure that the tap on the water supply is fully opened before operating the machine.
6. After chemical/detergent use, flush the facility for a few minutes with clean water.

Standard Operating Procedures
Instructions
1. High pressure cleaning should be carried out in an area isolated from other hazards and/or
workers, or steps taken to prevent exposure of persons to the high pressure cleaning process.
2. Persons should not operate high-pressure cleaners unless they have been instructed in the
hazards and the means of safe use and operation of the equipment, including the reading and
understanding of all motor and operation manuals.
3. All persons using high-pressure cleaners are to use personal protective equipment (PPE)
appropriate for the task and the equipment used.
Task Sequence
Identified
Hazards in Task
Key Processes to be Followed
Precautions / PPE
Required
1. Preparation
Electric Shock
Skin irritation
Burns, risk of fire
Care must be taken to ensure that key
components such as the motor is not
sprayed and are kept out of water/spray and
splash back, and preferably above ground.
Follow instructions when adding chemical
cleaning agents to the high pressure
cleaner.
Exercise caution when igniting gasoline.
Keep unit well clear of
working area.
Hand protection must
be worn.
No smoking or naked
flames in the vicinity.
2. Operation
Foreign matter in
eyes
Skin irritation
Slips and falls
Noise
Water splash will contain cleaning agent and
foreign matter from article being cleaned,
which may splash back towards operator.
High Pressure water injection and over
spray and splash back will result in
operator’s clothing becoming wet with
contaminated water from cleaner.
Operator may face tripping hazards.
Combustion engines may generate
excessive noise levels.
Wear safety goggles
and/or face shield. Keep
hands and feet clear.
Appropriate task
clothing Inc. wet
weather clothing and
waterproof footwear
required.
Keep hoses organised.
Slip-proof stable
footwear and remove
grease and other matter
from floors in operator’s
vicinity.
Wear hearing
protection.
3. Risks to
other persons
Splashing
The distance that water will be ejected over
depends on the shape and velocity of the
water jet. Exclusion of persons other than
those actually involved in the cleaning task
should be made to prevent injury from water
and water-borne particles and cleaning
agents.
Prevent unauthorised
entry into are where
cleaning is being carried
out.
