IMPORTANT USER GUIDANCE
TORNADO P2: MINI BOWSER +
PRESSURE WASHER
READ THESE INSTRUCTIONS BEFORE USE
GENERAL: The Tornado P2 is a trolley mounted
pressure washer equipped with a 150 litre water tank,
high-pressure pump, 30 metre reel-mounted high pressure
hose and jetwash lance. A recoil-start Honda petrol engine
powers the pump - delivering 13 L/min at 2200psi / 150 bar.
The tank can be filled through the lid or by coupling a hose to the refill valve on the side of the
tank. The Tornado is narrow enough to pass through a standard door and may be filled in
advance before wheeling it to the required location - helpful where there is no water supply.
Envirogard’s hire units come with a 30m hose - useful where access is tight or space constraints
are limiting. A chemical pick-up also allows cleaning / foaming agents to be added in-line.
PRE-USE CHECKS / FILLING: Visually inspect the trolley, water
tank, engine, pump, hose, reel and jetwash lance before use; if
damaged do not use – contact the supplying hire depot.
Check the lubricant level of the gear box, the high pressure pump
and the Honda engine; replenish as necessary. Ensure there is
petrol in the fuel tank; replenish fuel while the engine is cold.
Ensure there is water in the tank before starting the engine – dryrunning will damage the pump. To fill the water tank locate the
Mini-Bowser on a level surface capable of supporting the
equipments weight - 240kg once filled. Apply the castor brake;
use wheel chocks if ground conditions are poor.
Open the water tank and check the gauze water filter inside the
tank is not blocked (see image right), then return filter to the tank.
Either connect a hose to the tank coupling marked “Automatic
Fill”, or fill through the tank lid. When the tank is full secure the lid
closed; the trolley may be wheeled to another location if required.
Unlock the hose reel, deploy the length of hose required and
connect the jetwash lance using the quick coupling.
OPERATING INSTRUCTIONS:
Rotate engine switch to “ON” then:
1. Push the fuel lever to “Open”.
2. If this is the first use of the day slide
the choke lever to “ON”.
3. Pull the recoil to start the engine.
Once running gently return the choke
lever to the “OFF” position.
4. To flush any air in the system squeeze the jetwash lance’s
trigger until water flows freely from the nozzle.
5. Set the engine throttle control to “Fast”. The unit is now ready
to begin work.

6. Hold the lance firmly in
both hands when squeezing
the trigger -it will “kick back”.
Use only the hose, lance and
nozzle supplied with the
machine; never attempt to
connect / disconnect these
while they are pressurised.
If you are not using the lance
for 5 minutes or more – STOP
the machine. The pump will
overheat if it is left to run with
no water passing through it !!!
Spray Pattern is adjustable from Pinpoint to Fan spray by rotating the lance nozzle (see above).
Spray Pressure can be adjusted by rotating the Unloader Valve at the high pressure pump; a
gauge on the pump displays the delivered pressure. Pressure can also be adjusted on the
lance by rotating the nozzle between Pinpoint jet (high pressure) and Fan spray (low pressure).
If you wish to Spray Detergent place the
chemical pick up pipe in a detergent container
and rotate the lance nozzle to low pressure;
when you trigger the lance detergent will now
automatically be drawn into the system.
You adjust the ratio of detergent-to-water by
rotating the lance nozzle - towards Fan spray
will increase the amount of detergent, towards
Pinpoint jet will decrease the amount of
detergent.
To jetwash without detergent simply increase
the pressure at the spray nozzle, or remove
the pick-up pipe from the detergent container;
no more detergent will be drawn in and
residue in the line will soon clear.
7. TO STOP: reduce engine speed to idle then turn the engine switch to “OFF; when the engine
has stopped move the fuel lever to “Closed”. Dissipate any residual pressure in the machine by
activating the trigger of the jetwash lance.
Ensure this equipment is protected from frost at all times – empty the tank and hoses of residual
water. Store in a frost free environment under cover.
When you have finished with the equipment empty the tank of ALL water – there is a low level
drain in the tank to facilitate this. Wind the H.P. hose onto the reel, ensure the hose-reel lock is
engaged, the jetwash gun is secure, and the lance is in its holder. Clean the equipment
thoroughly prior to returning it to the supplying hire depot.

CAUTIONS / WARNINGS
IN CASE OF EMERGENCY: TURN THE ENGINE SWITCH TO “OFF” TO STOP MACHINE
PRESS JETWASH TRIGGER TO DISSIPATE RESIDUAL PRESSURE.
IF NOT USING THE TORNADO - STOP THE ENGINE WHEN LEAVING IT UNATTENDED.
This equipment is mobile and can be used and located in many different environments. Users are
therefore reminded of the need to ensure that all tasks and locations are risk assessed before activity
commences to ensure that all significant hazards are identified with appropriate precautions put in place.
The Tornado Jetwash is not designed nor intended for use in explosive or flammable atmospheres. The
petrol engine will generate exhaust fumes; the machine should be located in well-ventilated areas where
exhaust fumes are able to safely disperse.
This equipment is designed for high pressure cleaning (150 bar). This equipment ejects water at high
velocity and water jets are dangerous if misused. The jet/spray must not be directed at people, animals,
the machine itself, non-waterproof, fragile or electrical equipment, nor power cables. Do not attempt to
couple or un-couple tools, hoses or nozzles while the equipment is pressurised.
The equipment should be operated by an able bodied adult competent in the use of pressure washers up
to 150 bar / 2200psi. This equipment must not be used by minors or anybody under the influence of drugs
or alcohol. The work area should be demarcated and exclude other people from the jetwash spray zone.
Personal protective clothing must be worn. When operating the Tornado use an impact resistant visor or
goggles and ear defenders as a minimum. Water jets can generate high noise levels and produce a high
impact force, so when using the jetwash protective (waterproof) clothing, gloves and boots should be
worn in addition. Some jetwash applications may generate an aerosol containing pathogens e.g. guano
removal, the cleaning of animal by products etc; the user must assess whether RPE needs to be used in
this situation.
The engine and pump generate noise and the level varies according to engine speed; the equipment has a
Guaranteed Sound Power of LWAd 84dB. The jetwash lance is supplied with a 30 metre hose so where
possible locate the machine away from the cleaning activity and persons who might be affected by the
noise. Personnel obliged to work in close proximity to the machine must use hearing protection. If the
machine is operating in a wholly or partially enclosed space from which noise cannot readily dissipate
Users should consider conducting a noise survey to identify if extended mandatory hearing protection
zones are required.
This equipment contains water - do not allow it to freeze !!! If the pump has frozen DO NOT attempt to
start the engine; allow to thaw and inspect for damage before use. If possible store indoors during frost;
if this is not possible you must introduce anti-freeze (25% solution) via the tank; operate the engine at low
speed to draw it through the pump, hoses, lance and spray nozzles: this will protect down to approx – 5°C.
Before next use flush with clean water and collect the antifreeze solution for re-use (do not dispose of
antifreeze to the environment).
Legionella bacteria can grow at temperatures between 20°C and 45°C, particularly in dirty or
contaminated water. For this reason always fill the bowser with cold, clean, potable (drinking quality)
water only. If you will not be using the equipment for a few days drain the equipment of water. Before use
always purge the equipment using clean water, operating the engine at low speed to minimise production
of spray.
If ambient conditions are such that water temperature is sustained above 20°C consider treating the tank
and flushing the equipment periodically with a sanitising agent such as Milton. The user’s attention is
drawn to HSE’s guidance on Legionella ACoP L8; depending on your work environment and prevailing
temperature it may be necessary for you to include the equipment within your Legionella management
programme.
Fuel & Lubricant: petrol is flammable – take care not to cause a fire - top up fuel and check lubricant
levels with the machine shut down and in a cold state. Lubricant levels should be checked DAILY.
Ensure this equipment is protected from frost at all times – empty the tank and hoses
of residual water. Store in a frost free environment under cover.
Clean the equipment thoroughly prior to returning it to the supplying hire depot.
Equipment returned in a dirty or contaminated condition may be refused and will be charged.
