Micron Ulva+ Instruction Manual page 13

Check that the correct number of batteries is being used for the intended application –
five for water-based products to be applied at 10 to 20 litres/hectare, six to eight for
ULV formulations to be applied at 1 to 3 litres/hectare. The number of batteries can
be altered by removing both battery adjustment screws on the battery case, pushing
the extension tube into the battery case as far as it will go and replacing both battery
adjustment screws at the desired setting. Atomiser disc speed can be checked using a
tachometer – and should be 4,000 to 6,000 rpm for water-based treatments and 7,500
to 10,000rpm for ULV treatments. The operating position of the ULVA+ should be
so that the feed nozzle is as close to vertical as possible. The spray head can be
adjusted to accomplish this by using the head locking sleeve.

Before spraying for the first time use water only to check the operation of the sprayer.
Put some clean water in the bottle and add a small amount of detergent. Check for
leaks. Switch on the sprayer with the bottle below the spray head and then turn the
sprayer over so that the bottle is above the spray head (spray liquid will then flow
through the feed nozzle onto the atomiser disc). This is the spraying position, and
spray will immediately be emitted. Start walking as soon as the sprayer has been
turned over. Practice using the sprayer by walking along a few metres and then
stopping spraying (see 'TO STOP SPRAYING').
