3. WARNING FOR HANDLING ACCUMULATOR (2190-2528, 190-00099)
Accumulator

shut down. Activation of any controls may enable selected function to operate under force of gravity.
When shutting machine down, lower front attachment to ground. After engine has been shut down, turn key
to "ON" position and move joystick controls to release pressure in accumulator. Remove key.
WARNING!
Explosion hazard:
• Keep away from flame.
• Do not weld or drill.
CAUTION!
Any raised attachment will lower to ground if accumulator holds a charge.
IMPORTANT
Refer to Shop Manual for service procedures. Do not release any pilot lines until pressure within
accumulator has been released.
