Machines have provisions for being bolted to the bench.
C. Operator's Chair
The operator's chair should swivel, and should have independent seat height and back rest adjustments. The
seat and back rest should be padded, and the back rest should be large enough to provide support both
above and below the waist line.
In use, the chair should be far enough under the bench so that the operator's back is straight and is supported
by the back rest.
D. Foot Switch
When the operator is correctly positioned in front of a machine equipped with a foot switch, the foot should
rest on the switch comfortably. The foot switch should be movable, so that its location can be readily changed
when the operator shifts position to minimize fatigue. Placing the switch on a rubber mat keeps it movable
while preventing unintentional sliding.
The preferred foot switch location varies to some extent among operators. Some operators prefer the switch
located so that their foot rests on the switch when their feet are in the natural sitting position (calf of leg
perpendicular to the foot). Others prefer the leg to be slightly in front of the natural position. The important
thing to remember is that the foot should be at approximately 90_ (right angle) to the calf when resting on the
switch. Those operators who prefer the foot switch slightly in front of the natural position may require a
wedge-shaped block placed under it.
E. Scrap Removal
A scrap bin is provided with the DCC terminator to capture the scrap chips.
