ACCUMULATOR OPERATION CHECK
CAUTION
q
Before starting check operations, make sure that no person or other obstacles are in the surrounding ar-
ea.
Check nitrogen loading pressure as follows.
1.
Stop the machine on a solid and flat surface.
2. Place the working tool as extended as possible (fully extend-
ed boom and bucket in discharge position) and keep it 1.5 m
(A) away from the ground..
Carry out the operations described in points 3-5 within 15 sec-
onds.
Pressure in the accumulator descends gradually when the engine
is stopped. Therefore, the check must be carried out immediately
after the engine is stopped.
3. Keep the working tool at the maximum distance, turn the
start-up key to OFF and stop the engine.
4. Turn the start-up key to ON.
