Preparation of Hose and connection
・
Size of Hose;
The hose should have an inside diameter of 19mm.
△
！
CAUTION;
If the hose length is too long, this will result in reduction in air
pressure and reduce the power.
Please refer to the chart below concerning the reduction in air pressure.

※
Above table shows the volume of pressure loss at each air pressure level and
volume. The secondary air pressure at the hose outlet port is the volume deducted
each volume of pressure loss from the air pressure at the hose inlet port.
※
If the hose length is longer than 10m, the hose length and volume of pressure loss
are proportionally related. If the hose length is 20m, the volume of pressure loss is
double the volume on the above chart.
４．
Inspection of Wire Rope.
△
！
CAUTION;
Do not use a Wire Rope which has a kink or is deformed.
(See sketch to the right) Do not use a wire rope which
has broken strands. This will result in serious injury or
accident.
