CAUTION

Preventing damage caused by over-tightening

Do not over-tighten nuts and bolts. Over-tightening can strip the threads or break the bolts. Apply the appropriate torque values.

CAUTION

Personal safety and protecting the equipment

Use a dolly truck, forklift, or hoist whenever possible when handling and moving the equipment, as power equipment is heavy. If a forklift is used, do not remove the packing material before having moved the equipment to its final location. If a dolly truck is used, the packing material can be removed in the reception area. When handling cabinets with equipment installed in them, exercise care to ensure they do not tip over, as they can be top heavy.

CAUTION

Preventing personal injury

When cutting material, wear gloves and goggles. Break all corners and sharp edges with a flat file.

CAUTION

Optimizing the life of the equipment

Make sure there are no obstructions in front of the ventilation openings that can restrict the flow of air.
