NOTICE

The equipment was tested with lightweight oil,

the equipment for the first time.

• To reduce the risk of static sparking, which can 

cause fire or explosion, always hold a metal part of 
the gun firmly against the metal pail when flushing. 
This also reduces splashing.

• Always remove the spray tip before flushing.

• Only metal pails, which are conductive, should be 

used as solvent pails when flushing.
