down the engine and allow it to cool down. Otherwise,
you could be burned.
• Before commencing any work on the machine, place a
"Do not operate" tag on the right-hand control arm.

your CASE CONSTRUCTION Dealer. Never try to
carry out any servicing operation on the accumulator. If
this instruction is not followed serious injury can result.
• The accumulator is charged with nitrogen under high
pressure. Do not weld or allow flames to come near to
the accumulator.
• There is high pressure fuel in the feed pipe when the en-
gine is running and immediately after it has been shut
down. Wait for 2 minutes after engine shut down be-
fore you do any maintenance or inspections to allow
the pressure to drop in the pipe.
• High-voltage is charged to the controller and/or to the
