(7) Draining Liquid from the Spill Containment
Drain Pre-operation
1) Set a receptacle under the drain port of the spill containment to catch the liquid.
2) Remove the plug (R 1/2") of the spill containment drain valve and turn the lever to
"OPEN".
3) After draining the liquid, turn the lever to "CLOSE", and apply sealing agent to the
plug (R 1/2") or wrap it with sealing tape before tightening the plug.
<Note>

Secure the drain valve body using a spanner or similar tool so that it does not loosen
when removing/installing the plug by turning it.

It is possible that there is a fuel or oil leak if the drained fluid contains oily components.
If this occurs, check for leakage locations.

Although the fluids that can leak internally consist of oil, fuel, cooling water and
battery fluid, the spill containment does not have a function that can separate
rainwater that has leaked into the equipment from these internally leaked fluids.
Properly dispose of liquid drained from the spill containment in a manner according to
the applicable laws and regulations.
