Regarding with O-ring replacement (page 17):
・High pressured fluid on hose reel is very dangerous.
Shut off the fluid supply and set 0 pressure in the hose.
・Allow the hose to fully wind onto the drum to give the minimum winding tension
before carrying out replacement.
・Always put up instruction signs ("Equipment being inspected", "Do not open the
valve", etc.) before carrying out O-ring replecement.
・After finishing O-ring replacement, carry out the fluid leakage test on joint and
each connection part.
Regarding spring replacement (page 19):
・High pressured fluid on hose reel is very dangerous.
Shut off the fluid supply, and set 0 pressure in the hose.
・If the winding side hose is disconnected from mating equipment, the drum may
suddenly rotate.
Allow the hose to fully wind onto the drum to give the minimum winding tension,
and work with more than 2 people divided into the person who secure the drum
and the person who disconnect the hose.
Allow the disconnected hose to wind around the drum, and slowly turn the drum
until the winding tension in the drum is released.
・Never disassemble the reel until winding tension is released.
The spring will burst out and cause personal injury.
Even if the spring seems to be broken, never disassemble before ensuring no
winding tension remains by rotating the drum by hand.
・Never disassemble the reel using any other disassembly procedure.
If disassembled incorrectly, the spring will burst out and cause personal injury.
・Never remove the spring from the spring case.
If removed, the spring will expand explosively and cause personal injury.
・Follow the instructions for handling and disposing of the spring.
・Always put up instruction signs ("Equipment being inspected", "Do not open the
valve", etc.) before carrying out spring replecement.
