this Pneumatic Needle Scaler. Operators must
be made familiar with the instructions in
this
Warning
Operators under 18 not allowed to operate this
High Pressure Washer. Operators must be made
familiar with the instructions in this manual
before attempting to operate the High Pressure
Washer. Ensure that job site is clear of bystand-
ers. e high pressure jets are capable of causing
serious injury do not direct spray on people or
animals. Do not spray electried equipment.
Caution

Warning
Use only for high pressure cleaning, do not use
for any other application.
Warning
Safety and protective clothing, eyewear, head-
gear, ear protection, gloves and footwear to be
worn during operation of this High Pressure
Washer. Please see Table C at end of this section.
Warning
While starting operation and also during opera-
tion there is a considerable kickback force from
the lance due to the high energy generated, be
aware of this at all times and keep a rm con-
trol on the direction of the spray jet. Always use
both hands to operate the gun.
Warning
is High Pressure Washer is not designed for
use in an explosive environment.
Warning
Medical attention
Personnel who sustain injuries caused by high
pressure jets MUST be given immediate hospital
attention. It’s important to apprise the medical
attendants of the manner in which the injury
has been caused, namely a high pressure jet.
Caution
Keep the gun trigger locked when not operating.
Warning
Completely turn o the machine and disconnect
air supply line before attempting any service.
Read Assembly and Dis assembly instructions.
Warning
Take care not to exceed the maximum 7 bar
(100 psi) supply air pressure. Use a lter and
regulator and lubricator as close to the equip-
ment inlet as operation will allow to ensure a
clean and regulated and lubricated air ow.
Safety wear mandatory while operating high
pressure washer
Warning
Eye and face and ear protection must be worn at
all times during operation of the High Pressure
Washer. ere is a chance of ying debris from
the jobsite and the quality of wear should be
such to protect against such ying debris such as
akes of the removed layer.

And Fit Breathing cap provided with pump. Do not t Oil Plug.
Caution – a) If oil plug tted aer lling oil instead of breathing cap- Pump will over heat during use
and will damage all internal parts of pump and machine will stop working / developing pressure.
b) If oil is lled fully in pump up to top / maximum level of Oil indicating window, there will be no
space for breathing of oil during use and pump will be over heated which will damage pump internal
parts.

Safety checks before and after operating the High Pressure Washer
Air Supply.
• Ensure that an adequate pressured air supply is
available at 6 bar and at least 250 cfm.
• PW200 is supplied with a FRL unit. Always make
sure to top up lubricator with specied oil grade __.
Failed to do so will cause pre-mature failure of air
motor.
Lubrication.
• e oil sump in the Pump unit should contain
SAE15W40 grade oil.
• Ensure that the oil is at the half level by looking at
the transparent window.
• If the number of hours has crossed y, drain out
the oil by opening the Oil drain plug (4) at the side
of the pump housing. Re x the plug and open the
Vented oil cap (4) to top up oil to the correct level
(Refer g on page 11). ereaer repeat aer every
500 hours of use or whenever the level of oil has
dropped or looks contaminated.
Check list before starting the High Pressure
Washer.
• Check safety wear mentioned earlier in warnings.
• Check the hoses, especially the high pressure hoses
for damage or leaks.
• Make sure that the air supply is maintain by a pres-
sure regulator.
• Make sure that pneumatic hoses are not damaged
and all the connectors between gun, lance, hoses
and pump are secure.
• Make sure that the lter cone on the water supply
in in place.

to start the jetting.
• Adjust the output pressure as required by the pres-
sure regulator.
Warning
keep distance from gun tip to job at
least 8 inches.
Warning
is high pressure washer is a high powered
High Pressure Washer and it is imperative that
it must be operated by a competent and trained
operator. See warnings.
Warning
e high pressure washer needs a constant sup-
ply of water during operation, any starvation of
water to the High Pressure Washer will result in
overheating and quick damage to High Pressure
Washer.
Warning
With the motor running and the jetting o, the
high pressure water circulates in the circuit. DO
NOT pause jetting for more than TWO minutes.
Instead shut down the high pressure washer see
“Shutting down” later in this section
Changing spray nozzle tips
• Choose appropriate nozzle.
• Engage the trigger lock
• Pull back the collar
• Remove spray tip
• Install desired tip,
• Release collar
• Tug on tip to ensure proper seat
Cleaning solution injection
All Teryair high pressure washers have a fa-
cility of injection of Cleaning Fluids to aid in
the cleaning process.ere are several brands
& types of cleaning solutions available in the
market today. Whichever you choose make sure
it designed for use in high pressure washer. It
should say so on the level, if it does not say it,
don’t use it.
Warning: Never use bleach or bleach based
products as they can damage the pump.
• Once you have your cleaning solution is
ready to go, check to make sure that injec-
tor tube is securely attached to the pump as
shown.

FF-MM-311-REV - 01

Operation and Maintenance Guide Pneumatic Pressure Washer
• en insert the other end into the cleaning
solution.
• A pressure washer will only siphon clean-
ing solution when in low pressure mode.
So a lowpressure soap nozzle must be use
on the gun + lance ( Refer Spray tip detail).
• Caution
Aer cleaning Fluid application it is recom-
mended to disconnect the injection system to
allow clean water to rinse through the system
for few minutes.
Shutting down
• DO NOT turn o water source before
switching o the motor.
• Switch o the air supply and disconnect
the air hose.
• Turn o the water source.
• Pull the lance trigger to relieve any residu-
al water pressure.
Storage
• Disconnect the gun from the high pressure hose
and the hose from the pump.
• Hold gun vertically and depress trigger to re-
move all residual water from the gun and lance.
• Drain the hose too in a similar way.
• Remove the water supply hose and drain.
• Run the pump for ten seconds to eject any resid-
ual water that may have remained in.
• Store in a clean and dry place.
• Store under a tarpaulin is recommended.
