The TTV 678 ride-on scrubber dryer has an optional automatic chemical-dosing system.
Simply ll the 5 litre chemical dosing bottle and the machine will deliver the correct mix ratio as set by the operator,
depending on the oor and cleaning conditions. (See page 34)
To ll the chemical dosing bottle, rst lift up the waste-water tank (Fig.25), remove the dosing bottle, unscrew the bottle
cap (Fig.26) and ll with appropriate cleaning chemical. Replace bottle cap, ret dosing bottle (Fig.27) and carefully lower
waste-water tank.
The machine is now ready to be driven to the cleaning site.
Before performing the cleaning operation, place out appropriate warning signs and sweep or dust-mop the oor.

Note: always ensure that the waste-water tank is empty before lifting.
After use, ensure the chemical dosing tank is emptied, cleaned and relled with clean water.
The dosing pipes also need to be cleaned and ushed through with clean-water for at least 60 seconds.
