Tarmo 311311 Instruction Manual page 2

Releasing pressure and water from the spray gun:
It is very important to release pressure and water from the spray gun before
using the high-pressure washer. Squeeze the trigger to allow any air that is
trapped inside the device and hose to escape. Continue to squeeze the trig-
ger until a steady stream of water comes from the nozzle. (This process may
take up to 2 minutes.) See the Operating Instructions section for this process.
OPERATING INSTRUCTIONS
! This device is to be connected to a cold water source ONLY.
! Before working, make sure that you inspect the water inlet filter and the
nozzle. Make sure there are no impurities.
• Connect the outlet hose to the high-pressure washer and connect the
spray gun to the outlet hose.
• Connect the nozzle and nozzle extension.
• Check that the water inlet filter is clear of any blockage.
• Connect the inlet hose.
• Check that the hose is not twisted.
• Turn on the water and check for leaks.
• Press the trigger to allow air to be released through the pump and hoses.
Lock the trigger.
• Plug in the device and turn it on.
• Unlock the trigger and use the high-pressure washer.
Shut down
1. Turn off the motor (push the switch to the OFF position).
2. Unplug the device from the socket.
3. Turn off the water supply.
4. Press the trigger of the spray gun to depressurise the system.
5. Disconnect the inlet hose from the high-pressure washer.
6. Wipe all surfaces of the device with a damp clean cloth.
7. Engage the spray gun's safety lock.
CAUTION: ALWAYS turn off the device's motor BEFORE turning off the de-
vice's water supply.
Serious damage could occur to the motor if the device is run without water.
CAUTION: NEVER disconnect the inlet hose from the device while the system
is still pressurised. To depressurise the device, turn off the motor, turn off the
water supply and squeeze the trigger 2–3 times.
ADJUSTABLE SPRAY NOZZLE
Turn the spray gun into the closed position first: hold the rear part of the spray
nozzle, then turn the front part of the spray nozzle clockwise. Water will spray
out from the spray nozzle in a fan pattern (fig. 2). Turn the front part of the
spray nozzle anticlockwise. Water will spray out from the spray nozzle lin-
early (fig. 1).
Low/High-pressure adjustable spray gun
Using high pressure:
Make sure the trigger is released and there is no water spraying. Then turn
the rear part of the spray nozzle anticlockwise (fig. 4). Squeeze the trigger
and the gun will spray water with high pressure.
Using low pressure:
Make sure the trigger is released and there is no water spraying. Then turn
the rear part of the spray nozzle clockwise (fig. 3). Squeeze the trigger and
the gun will spray water with low pressure.
CAUTION: Selection of high or low pressure takes place by turning the noz-
zle. You must make this pressure selection with the spray gun in the closed
position.
NOTE! The water inlet filter must be inspected regularly, so as to avoid block-
age and restriction of the water supply to the pump (fig. 5).

USING DETERGENT
Add the cleaner into the container at the back of the device and remove the
head of the nozzle as shown in picture 6.
Turn the lower lever on the front panel of the pressure cleaner to maximum.
When using detergents, the safety data sheet issued by the detergent man-
ufacturer must be adhered to, especially the instructions regarding personal
protective equipment.
Some detergents have been customised for use in high-pressure washers
for specific cleaning tasks. Using detergents that are not recommended for
using in high-pressure washers, such as dishwashing liquid, will clog the
chemical injection system and prevent the application of the detergent.
The cleaning power of detergents comes from applying them to a surface
and giving the chemicals time to break down the dirt and grime. Detergents
work best when applied at low pressure.
On vertical surfaces, apply the detergent starting at the bottom and work
your way upwards. This will prevent the detergent from dripping down and
causing streaks.
Foam cleaning method
Be sure to insert the detergent in the built-in tank on the back of the device
and remove the tip as shown in fig. 6.
SPRAY GUN SAFETY LOCK
Whenever you use the high-pressure washer spray gun, we suggest you grip
it in the right position, with one hand on the handle and the other on the stem.
When you stop the device, you must use the safety lock placed on the gun in
order to avoid any accidents.
NOZZLE CLEANING INSTRUCTIONS
A clogged or partially clogged nozzle can cause a significant reduction of wa-
ter coming out of the nozzle and cause the device to pulsate while spraying.
• Using the included tip cleaner or an unfolded paper clip, insert a wire into
Nozzle
the nozzle hole and move it back and forth until the debris is dislodged.
• Remove additional debris by back-flushing water through the nozzle. To
do this, place the end of a garden hose (with water running) to the end of
nozzle for 30–60 seconds.
DISTANCE AND ANGLE FROM SURFACE TO BE CLEANED
The optimum angle for spraying water against a surface is 45 degrees.
Spraying water against a surface at this angle provides the most benefi-
cial impact force combined with efficient removal of debris from the surface.
Another factor that determines the impact force of the water is the distance
from the spray nozzle to the surface. The impact force of the water is in-
creased as the nozzle is moved closer to the surface.
HOW TO AVOID DAMAGING SURFACES
Damage to surfaces being cleaned occurs because the impact force of the
water exceeds the durability of the surface. Never use a narrow high-impact
stream or a turbo/rotary nozzle on a surface that is susceptible to damage.
Avoid spraying windows with a narrow high-impact stream or turbo nozzle,
as this may cause breakage. The surest way to avoid damaging surfaces is
to follow these steps:
1. Before triggering the spray gun, adjust the nozzle to a wide fan pattern.
2. Place the nozzle approximately 1–2 metres and at a 45 degree angle from
