FITTING THE NOZZLE
Fit the nozzle through the nozzle cap and
tighten as shown. Make sure that the seals
are in good condition. If they are damaged
they should be changed otherwise the
nozzle may leak. If fitting the deflector
nozzle or flat fan nozzle ensure that it is
correctly orientated. The opening on the
deflector should be pointing forwards and
the flat fan at right angles to the direction
of travel.
If the sprayer is supplied with a Constant
Flow Valve (CFV) then this should be
fitted at the trigger/lance as shown.
STRAP ADJUSTMENT
With the sprayer on your back and filled as
if ready to spray adjust the length of the
straps for comfort as shown. For maximum
comfort use the waist strap as shown If the
straps are correctly adjusted the sprayer
should fit comfortably on your back with the
weight resting on your hips.
CALIBRATION
Before using the
SA15
the sprayer should be calibrated using water. This is important
as accurate calibration ensures that the correct dose of product is applied. Poor
calibration can result in either over-dosing or under-dosing both of which are wasteful.
The process of calibration involves measuring the three inter-related factors which
determine the volume of spray applied by the sprayer; flow rate, band width and
walking speed.
