SAFETY
MAINTENANCE
1. Use only NPK supplied replacement parts. NPK specifically disclaims any
responsibility for bodily injury or DEMOLITION GRAB damage that results from the
use of parts not sold or approved by NPK.
2. Use extreme caution in handling. A fully assembled DEMOLITION GRAB can
weigh over 2 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. The supplied safety bar (t79) MUST always be installed during transport, repairs,
dismounting and mounting to the carrier, changing the cutters and all other routines
at the attachment (GZ).
4. Wear safety glasses and protective clothing when working on the DEMOLITION
GRAB. 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 DEMOLITION GRAB.
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. When removing or installing mounting pins, beware of flying metal chips.
