2.0 SAFETY PRECAUTIONS

All operators should wear safety goggles when using this or any other

tachometer. Failure to do so could result in serious injury!

1. Check condition of housing, slide-on Contact Adapter and

split mounting hubs of push-in Contact Cone, Surface Speed

Wheel and any other accessories. Replace those that are worn,

loose-fitting or cracked. The Contact Adapter shaft should

rotate freely.

2. When operating in the contact mode, be sure Contact Adapter

fits snugly into the housing grooves.

3. When using the Surface Speed Wheel accessory, make sure it

its the tachometer shaft snugly. In operation, keep the wheel

perpendicular and parallel to the moving surface to prevent it

from running off the tachometer shaft.

4. Do not use the standard surface speed wheel for speeds in

excess of 1000 feet per minute. For higher speeds, specify the

optional Heavy-Duty Surface Speed Wheel (DT12) with

set-screw mounting.

5. Store the instrument in its carrying case when it is not in use
