1. Keep entire body, especially hands, arms and head out of the path of the falling
weight and tup at all times.
2. Only one operator should operate the machine at any given time.
3. Install the safety "H" bar supplied to ensure weight cannot drop whenever weight is
raised and work is being done on system. The safety "H" bar clips to the guide
columns.
4. Perform regular maintenance.
5. Never use the 50 lb. (22.7 kg) or heavier weight set when operating at velocities
above 14.5 ft/s (4.42 m/s).
6. Do not leave tools, spare parts or debris inside the safety enclosure when operating
the impact machine.
7. Do not handle the guide columns. They are easily soiled, which can seriously effect
impact test results.
8. Do not strike non-deformable objects with instrumented tups. If the tup strikes the T-
grooved baseplate, specimen support fixture or a non-deformable specimen, the tup
will likely be damaged.
9. Frequently check the crosshead weight retainer knobs or screws for tightness. They
should be securely tightened before performing impact tests. If these bolts are loose,
the crosshead can bind on the guide columns.
10. Always unplug the power cord when servicing or repairing the Model 8250.
11. Frequently check the hoist cable for damage.
12. When the optional pneumatic assist is installed, frequently check that the large
springs used to accelerate the crosshead are securely screwed to the rods that hold
them.
13. Always use the shock absorbers when pneumatically assisting the crosshead.
14. To prevent potential damage to the crosshead, make sure that the shock set installed
matches the weight set attached to the crosshead. This can be quickly verified by
matching the background color on the sticker attached to the shock with the color
coded dot located on the weight plates.
