Safety Information
Personal Safety (Continued)
• Do not touch parts that might be hot from operation. Allow parts to cool before
attempting to maintain, adjust, or service.
• Do not overreach. Keep proper footing and balance at all times. This enables
better control of the machine in unexpected situations. Extending your body too
far can result in a loss of balance and you may fall which will result in injury.
• Never place any part of your body where it would be in danger if movement
should occur during assembly, installation, and operation, maintenance, repairing
or moving.
• Keep in mind that the operator or user is responsible for accidents, hazards or
unexpected events involving the machine that occur to other people or their
property. It is the responsibility of the user to assess the potential risk of the area
where work is being carried out. The operator or user must take all necessary
precautions to ensure their own safety and that of others, especially on slopes or
rough, slippery and unstable ground.
Inspect Your Machine
• Check your machine before starting it. Keep guards in place and in working
order. Make sure all nuts, bolts, etc., are securely tightened.
• You must check the general condition of the machine before use.
• Never operate the machine when it is in need of repair or is in poor mechanical
condition. Replace damaged, missing, or failed parts before using it. Check for fuel
leaks. Keep the machine in safe working condition.
• Do not use the machine if the machine’s switch does not turn off the machine
when running. Any machine that can’t be controlled with the switch is dangerous
and must be replaced.
• Regularly check to see that keys and adjusting wrenches are removed from the
machine area before starting it. A wrench or a key that is left attached to a
rotating part of the machine may result in personal injury.
• If the machine should start to vibrate abnormally, stop the machine and check
immediately for the cause. Vibration is generally a warning sign of trouble.
• Avoid accidental starting. Be sure the switch is off before transporting the
machine or performing any maintenance or service on the unit. Transporting or
performing maintenance or service on a machine with its switch on invites
accidents.
• Do not tamper with or disable safety systems.
• Only use manufacturer-recommended attachments.
• Before using, always visually inspect to see that the tools are not worn out or
damaged. Replace worn out or damaged elements and bolts in set to preserve
balance.
• Keep the machine in good operating condition. Operating the machine in poor
or questionable condition could result in serious injury.
• Be sure all safety devices are in working order and warning labels are in place.
These items are installed for your safety.
!
!
• The operating noise of the machine can damage your hearing. When wearing
protection such as earplugs or ear defenders to protect your hearing. Long-term
and regular users are advised to have hearing checked regularly. Be especially
vigilant and cautious when wearing ear protection because your ability to hear
alarm warnings will be reduced.
• Noise emissions for this equipment is unavoidable. Carry out noisy work at
approved times and for certain periods. Limit the working time to a minimum. For
your personal protection and protection of people working nearby it is also
advisable for them to wear hearing protection.
• See Certificate of Conformity section for Outdoor Noise declaration of
. . conformity.

Safety Information
Vibrations (Where Applicable)
• Prolonged use of hand held (operated) machines will cause the user to feel the
effects of/from vibrations. These vibrations can lead to white finger (Raynaud’s
phenomenon) or carpal tunnel syndrome. This condition reduces the ability of the
hand to feel and regulate temperature, causing numbness and heat sensations
and may cause nerve damage and circulatory tissue death.
• Not all factors that lead to white finger disease are known, but cold weather,
smoking and other diseases that affect blood vessels and blood circulation as well
as large and long-lasting impact of shocks are considered factors in the formation
of white finger. Note the following to reduce the risk of white finger and carpal
tunnel syndrome;
• Wear gloves and keep your hands warm.
• Take regular breaks.
• All of the above precautions may help reduce the risk of white finger disease but
not rule out the carpal tunnel syndrome. Long-term and regular users are therefore
recommended to observe the condition of your hands and fingers. Seek medical
attention immediately if any of the above symptoms should occur.
Noise (Where Applicable)

Residual Risks
Even when tool is used as prescribed it is not possible to eliminate all residual risk
factors. The following hazards may arise in connection with the tool’s construction
and design:
1. Damage to lungs if an effective dust mask is not worn.
2. Damage to hearing if effective hearing protection is not worn.
Health defects resulting from vibration emission if the power tool is being used over
longer period of time or not adequately managed and properly maintained.

Pressure Washing
IMPORTANT – When using pressure washer, don’t allow the machine to idle for a long
time. This will overheat the pump and cause damage. If not using for extended periods of
time, turn off the machine.
• With the Machine running with a constant water supply, Choose the nozzle best suited
for your activity. Simply pull the Lance Trigger and the machine will expel high pressure
water.
• The trigger has an inbuilt Safety Lock Out. When not using the machine, to avoid
accidental overspray, simply extend the Safety Lock Out. There is a slot which the Lock
Out will sit within

Soap Inlet
Soap Inlet Hose
• Place the Soap inlet, and inlet hose into your container with soap. Follow mix instructions
supplied by the manufacturer of the soap. If no instructions, assume it requires no mixing.
• The Soap inlet will draw the detergent through the hose into the pump, passing it through
the lance. Some aftermarket brands make Soap Bottles which are compatible with the
Lance. If you wish to use one of these, there isn’t any benefit to additionally drawing soap
through the pump as shown.
