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

2. Pull the shell down until it is completely
off the corners of the gauge, the pull the
gauge forward and out of the shell.
3. Replace the shell by sliding the gauge
bottom first into the large center opening,
then, one at a time, slip the corners of the
shell back over the gauge.
