Maintenance and technical information.
The life of your sprayer will
depend on the care it receives throughout its life. It is the
operator's responsibility to ensure that the machine is not only
correctly operated, but also to ensure that any maintenance
operations outlined in this manual are carried out. Please remember
that you are obliged to keep your sprayer in top working condition
under the various acts and codes of practice mentioned previously. If
you are unsure of how to carry out any of the maintenance or repair
operations, please do not hesitate to enlist the help of your dealer
or T.J. Frazier Ltd. Cleaning
The sprayer should always be kept
clean and MUST be washed out daily whether you are using the same
chemical the next day or not.
DO NOT leave chemicals in the tank
overnight if you can possibly avoid it. If your sprayer does not have the tank wash system fitted, particular care must be taken in washing the inside of the top of the tank, using a hosepipe and brush if necessary.
To get rid of any remaining traces
of chemical in the sprayer, it is generally better to wash it through
several times with relatively small amounts of water i.e. 100-200
litres than it is just to spray one large amount through.
For a thorough wash out, firstly
add about 200 litres of clean water to the sprayer and circulate it
whilst washing the inside of the tank with a hose. Then spray the
water out through the spray lines and finally drain out the tank.
During the washing process direct
the water through the chemical inductor for a while, and operate the
flush ring, can-wash and flushing hose. Also turn the booster
agitator on for a while, if you have not been using it, checking that
the nozzles in the tank are not blocked. Whilst spraying the water
out of the tank turn the boom section switches off for a few moments
to flush out the balanced return pipes back to the tank. It is
important that all the hoses on the sprayer are flushed through
during the cleaning process.
After the initial flush out repeat
the process adding some cleaning agent to the water and, when you
have finished, give it a final rinse through with clean water again.
Leave the pump running for a while with the tank drain open each time
to empty as much water as possible out of the system. You cannot hurt
the spray pump by running it dry.
If you have been spraying with a
particularly "potent" or concentrated chemical, circulate a
detergent mix through the sprayer and spray lines and leave to stand
overnight. Before commencing spraying circulate the mix again, spray
it out and then flush through twice more with clean water remembering
to ensure that all the hoses are flushed through as above.
The outside of the sprayer should
also be cleaned down immediately after use.
Please remember to follow the Code
of Practice etc. when washing the sprayer out and disposing of tank washings. When you have finished, remove all the filters from the sprayer and check them for cleanliness. Clean them off with brush in a bucket of water if necessary and then replace.
