STORAGE OF HYDRAULIC HAMMER
For short term storage between jobs, place the hammer horizontal on wood blocks
(t20). Be sure the tool (HH) is liberally greased and the hydraulic hoses (AO) are
capped. Cover with a waterproof tarp (t21), not shown.
If the NPK HYDRAULIC HAMMER is not to be used for a long period of time (months),
the following storage procedure is recommended:
1. Discharge the gas pressure using the gas charge valve (M).
2. Remove the tool (HH) and push the piston (N) all the way in.
3. Grease the exposed end of the piston (N).
4. Grease and reinstall the tool (HH) at bushing areas.
5. Plug the hydraulic hoses (AO).
6. Cover with a waterproof tarp (t21), not shown.
