Disassembly And Assembly - YAMADA KGK-400 Series Instruction

- Please contact the store you purchased the product or our business office if a metering error has
happened soon even though it didn't occur at the beginning of use.
- When handling silicone grease, be sure to select a designated valve for silicone grease. If a grease or
adhesive metering valve is used, seizure of a valve and sleeve will occur, resulting in malfunction of a
metering valve.
If material flows out continuously even after a metered shot has been dispensed, it may be caused by
conditions of inlet or outlet lines or a procedure taken to restart operation after repair. Please follow the
following recovery procedures.
- When using a metering valve for the first time including after repair, run the valve without connecting
dispensing equipment, coupling, hose, or any other accessories to a material outlet. Keep running the
valve until all trapped air inside a material supply pump, hose, pipe, and metering valve is expelled
completely. Make sure that the valve is closed before making connection to the outlet.
- When material continuously flows out from dispensing equipment or an outlet of a secondary pipe, the
outlet of the metering valve doesn't generally have a defect. In most of these cases, it is caused when a
pipe line is too long or short or when material of a pipe is flexible. To solve this problem, repeat
"Discharge" and "Standby" until continuous flow stops.

6. Disassembly and Assembly

- Release residual pressure completely BEFORE disassembling metering valves.
- Wash the parts with wash oil and apply a thin layer of lithium grease BEFORE reassembling.
Be extremely careful not to let dust and dirt attach to any of the parts.
