SAFETY

MAINTENANCE

1. Use only NPK supplied replacement parts.
responsibility for bodily injury or MATERIAL PROCESSOR damage that results
from the use of parts not sold or approved by NPK.
2. Use extreme caution in handling. A fully assembled MATERIAL PROCESSOR can
weigh up to 5 tons. Sub-assemblies range in weight from hundreds to thousands of
pounds. To avoid bodily harm, use lifting and securing mechanisms of adequate
capacity to support loads. Seek the aid of an assistant as much as possible, and
always when handling heavier sub-assemblies.
3. Use extreme caution when changing jaw sets, particularly in the field. Employ lifting
and securing mechanisms of adequate capacity to support the jaw sets. At least
two people are required to change a jaw set safely in the field.
4. Wear safety glasses and protective clothing when working on the MATERIAL
PROCESSOR. Wear thermal-protective gloves when handling heated parts.
5. Prevent exposure to hazardous fumes. Remove all paint, grease, and oil before
heating, cutting or welding on the MATERIAL PROCESSOR.
6. Be especially cautious around hydraulic lines. Hydraulic oil can be extremely HOT!
Avoid skin contact with hydraulic oil. It can cause severe burns!
7. Protect hands and body from hydraulic fluids under pressure. Escaping fluid
under pressure can penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting any lines. Search for leaks with a piece of
cardboard, or other object. If an accident occurs, see a doctor immediately!
Hydraulic fluid injected into the skin must be surgically removed within a few
hours or gangrene may result.
8. The pressure generated by the power intensifier on the MATERIAL PROCESSOR
exceeds 10,000 psi (690 bar), which is higher than commonly encountered on
hydraulic equipment.
inspection checks, use gauges, hoses and fittings rated at 15,000 psi (1035 bar).
For parts replacement, use only genuine NPK replacement parts. Contact NPK
Service Department at 1-800-225-4379.
9. When removing or installing mounting pins, beware of flying metal chips.
