Always have the plug inserted firmly. When the plug has dirt or oil, and the connection is incomplete, it may cause electric shock or fire. ◆ Do not have the electric cord connected with other electric devices or branched with other cords. It may cause fire.
- Page 5 ECOsaver Tetra CAUTION ◆ Install a filter driyer at the suction port. Otherwise the compressor may be damaged. ◆ An extension cord used should be a three-core cabtyre cable with a length of 20m or less when its wire diameter is 2.0mm or with a length of 30m or less when its wire diameter is 3.5mm An unsuitable extension cord (too thin or too long) may lead to starting failure or fire.
- Page 6 ECOsaver Tetra CAUTION ◆ When the Recovery Machine is dropped or hit, inspect immediately for damage, crack, dent, etc. Recovery under damaged, cracked and dented condition may cause injury ◆ Check every day if there is deformed or corroded area. ◆ If abnormal condition (strange smell, vibration, strange noise) is noticed, stop the unit and refer to the Page24 “ BEFORE REQUESTING REPAIR OR SERVICES” in the manual. ◆ Request for repair or service instead of disassembling for repair, contact the store where the machine was purchased.
