ACCUMULATOR CHARGING PROCEDURE
To receive the optimum performance from the hydraulic hammer, care must be taken to maintain
the proper nitrogen charge in the accumulator of the hammer. To assist with this, a charge kit is
available. Refer to Section D, Page 5.
NOTE: The customer supplied nitrogen tank MUST be equipped with a regulator!
The following is a step-by-step procedure that should be used to properly charge the accumulator.
These are written for use with the charge kit. The accumulator can be safely charged either on or
off the hammer, as long as these procedures are followed:
STEP ILLUSTRATION
STEP 1
If you haven’t already done so,
assemble all items of the Charge
Kit with the exception of Items 3
and 4. Note: The charge kit, with
the exception of items 3 and 4, is
to be stored as a complete unit
and does not require
disassembly.
Make certain that the shut-off
valve (12) is fully closed
(clockwise).
STEP 2
Remove the plug and o-ring from
the top of the accumulator cover
using a 22mm or adjustable
wrench. Replace with Charge Kit
Adapter (#3) and O-ring (#4).
