6.10.2 Works at accumulators
S Use only original Klemm parts! If not, you’ll loose warranty claim.!
S For ordering spare parts there are adequate part- numbers available
in our part lists. This is also valid for repair works!
S Watch the indicated torques for tensioning the screws!
S During disassemble - assemble of units, unit parts, seals,
watch the installation direction and location!
S Do not weld at accumulators for repair purposes!
S Part - assembly drawing shall be used for repairs!
S During works at open systems (drifter, rotary head) works like
oxygen cutting, grinding, welding etc. shall be avoided!
S Any mechanical damages, welding, pretensioning etc. are not allowed!
S The mounting of precision parts has to be executed carefully,
light moving, without jamming and uncontrolled forces!
S Before disassembling the accumulator the nitrogen has to be released:
- take off the cap plug.
- unscrew inlet screw carefully for approx. 1 - 1,5 revolutions, until
nitrogen escapes (hiss effect). Don’t take off the inlet screw completely,
until the pressure has been released completely.
S Disassemble the accumulator and clean all parts carefully.
S Check the parts on damages and change them, eventually the
whole accumulator.
S After each disassembly of an accumulator a new diaphragm,
new screws and seals shall be installed!
S Before assembling the accumulator each part has to be cleaned with non
explosive and non aggressive cleaner and pressurized air (don’t use
water, it leads to corrosion)!
S Fit diaphragm and seals according to the drawing. Oil the seal
edges and watch the assembling position!
S Assemble the accumulator according to the drawings.
S Fill the accumulator with nitrogen (N
2
) only!
S Use therefore only the original Klemm accumulator filling device
( P/N: 40753)!
S Watch the specified filling pressure of the accumulator!
S Don’t inhale nitrogen (N
2
)! work only in safe environment!
