 Electra–Screw

 compressors are the result of advanced engineering and skilled manufacturing.

To be assured of receiving maximum service from this machine the owner must exercise care in its operation and
maintenance. This book is written to give the operator and maintenance department essential information for day–
to–day operation, maintenance and adjustment. Careful adherence to these instructions will result in economical
operation and minimum downtime.

Danger is used to indicate the presence of a hazard which will cause severe personal
injury, death, or substantial property damage if the warning is ignored.

Warning is used to indicate the presence of a hazard which can cause severe person-
al injury, death, or substantial property damage if the warning is ignored.

Caution is used to indicate the presence of a hazard which will or can cause minor
personal injury or property damage if the warning is ignored.

Notice is used to notify people of installation, operation or maintenance information
which is important but not hazard–related.

This book covers the following models:
