USING THE VACUUM PUMP:
If the sprayer has not been used for some time or has been left with chemical in it then the pump
valves may become stuck. If this happens the pump will run but no liquid is pumped.
If this happens you can use the hand operated vacuum pump to prime the pump as follows:
1.
Empty the tank and spray hose of liquid
2.
Make sure the power switch on the knapsack is off
3.
Connect the hand pump as shown in the pictures below and lock the trigger on
4.
Pump the handle to draw some air and unstick the pump valves
5.
Clean the vacuum pump after use.
Sometimes when accessing the battery or changing a fuse it is possible to accidentally disconnect a
cable stopping the sprayer from operating.
The Battery box on the back of the sprayer includes the charging socket, fuse and battery. Use the
diagram (right) and troubleshooting instructions to resolve basic difficulties.
