OPERATING INSTRUCTIONS (LINEMARKER)
1.
Nozzle flow rate is determined by the pump outlet and the size of restrictor at the return elbow.
2.
Application rate will depend on nozzle flow rate and forward speed. Therefore to vary the concentration of
marker dye on the line the operator can vary speed, or if absolutely necessary by altering the size of
restriction.
NOTE
Too much restriction at the return elbow will increase spraying pressure and may cause the pump to ‘cycle’ (turn
on and off). Avoid pump ‘cycling’. This is caused by the automatic pressure switch (normally set at 60 PSI)
switching the pump off momentarily as pressure in the hose reaches 60 PSI (4 Bar).
3.
Mix dye, empty into tank and spray by turning on the pump with the master switch.
4.
Two adjustments can be made to set the line width.
(a) The entire nozzle body can be raised or lowered by changing the mounting hole used.
(b) The nozzle tip can be rotated through 360° to adjust the angle of spray.
Two Methods of Line Width Adjustment
5.
Always flush the tank and pump with clean water several times after use. Check the suction filter.
OPERATING HINTS
Pressure Gauge
The pressure gauge will indicate any variation in flow rates. If the pressure reading is suddenly higher than normal
then nozzle flow rate has been reduced by a slight blockage or kinked hose. If pressure is lower than normal,
either the battery charge is low, the pump is faulty or there is a leak in the hosing or fittings. Air should not be in
the hosing. If air is present, check the fittings between the tank and pump.
The nozzles may wear eventually after many years but in turf spraying, especially at the low pressures used,
nozzle wear will not cause major pressure fluctuations.
Nozzles
Be wary of blockages or of any distortion in the spray pattern. The standard nozzle supplied with the linemarker
unit is ‘015-80’. The bayonet nozzle cap aligns the nozzle and retains both nozzle and slotted filter. Routinely
check these filters, removing the cap by twisting half a turn clockwise.
Checkvalves
The non-drip checkvalves (4cm above each nozzle) should eliminate dripping. If dripping continues after pump
shutoff, unscrew the collar on the checkvalve and ensure that the diaphragm is sound and that there is no debris.
Pump
If a slight leak develops from between the pumphead components, gently tighten the pumphead screws. If
however, the leak persists or if a leak is observed from between the pumphead and the motor itself, cease
operation immediately and have the pump serviced.
CAUTION
Do not run the pump dry unnecessarily
