Method of drain removal;
Rust will develop leading to the cause of trouble if the drain is not removed from the compressor.
Remove the drain at the bottom of the air tank on your compressor. Remove excess water and oil.
Supply clean dry air to the hoist. (Refer to the compressor manual for details
）
２．
Piping
Refer to the diagram below for piping or installation. The main and secondary pipes should be larger
than the air hoist hose size. It the main or secondary pipe is smaller in diameter or too long, you will
experience pressure drop and this will reduce the performance of your hoist.
CAUTION
;
Always install an Air Filter, regulator and lubricator (Line Oiler)
near the hoist.
・
Always use an air filter, regulator and lubricator (line oiler) near the hoist
The size we recommend is a size larger than the actual piping size and for the air regulator we
recommend the pilot type regulator. If a pilot style regulator is not available, we recommend a
regulator one size larger than the standard size. (To keep the performance level for the hoist)
With regards to the lubricator (line oiler), we recommend a flow of 15-20 drops/min. of lubrication.
If air maintenance is not performed properly, this will lead to rust, malfunctioning and premature
wear of the internal parts, and this may result in personal injury.
