How to clean
Danger! Before every cleaning and storage, bring the sprayer into a
depressurised condition. Clean the sprayer every day after use. Do not let spray
liquid in the tank after use. After complete emptying fill the tank ¼ with water.
Pressurize tank and spray. After emptying, unscrew the spraying lance from the
trigger control valve (Fig. 16). Empty the line by opening the tank (Fig. 4-5), holding
up the line and simultaneously operating the trigger control valve. Depending on
the extent of dirt, clean nozzle and strainer with water after dismantling.
To do this, unscrew the knurled union nut, remove the nozzle and strainer from the
spray lance (Fig. 17) and clean. To clean the sieve tube on the trigger control valve,
loosen the hose clamp on the rear end of the handle and pull the handle off the
trigger control valve. Remove the sieve tube (Fig. 18) and clean it.

After cleaning we recommend the tank be hung upside down with the cover
open.
How to store
Before storing for a long period, it is necessary that all parts are completely dried.
