MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

PRESSURIZED ALUMINUM PARTS HAZARD

fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

skin and cause serious injury. To reduce the risk of an

injuiry from injection, splashing fluid, or moving parts,

follow the Pressure Relief Procedure whenever you:

• are instructed to relieve the pressure,

• check, clean, or service any system equipment,

• or install or clean fluid nozzle.

If you suspect that pressure is not fully relieved

after following the previous steps, using a rag very

slowly loosen the hose end coupling or a fitting on

the fluid line and allow pressure to be relieved grad-

ually, then loosen the part completely and clear the

clog.
