WARNING ◆ Only qualified persons are allowed to disassemble the pump. ◆ Do not modify the pump. It may lead to mechanical failure or accident. ◆ Do not put a finger or a stock to the turning part of motor. It may lead to accident or injury.
- Page 4 VACUUM PUMP WARNING ◆ Do not use the power cord concurrently with other electrical equipments and avoid overload connection. ◆ Do not pull the power cord to disconnect from the outlet. It may lead to electric shock, fire or injury. ◆ Do not use the pump in an area where gasoline, thinner or any other combustible gas may exist.
- Page 5 VACUUM PUMP CAUTION ◆ An extension cord used should be a three-core cabtyre cable with a length of 10m or less when its diameter is 2.0㎡ . An unsuitable extension cord (too thin or too long) may lead to starting failure or fire. ◆ Do not let visitors touch the pump. The pump should be used by a person who read through the instruction manual and understands it completely. ◆ Do not use the pump for purposes other than the original intent.
