15.4
If it is necessary to unfold the placing boom to do mainte-
nance work, the outriggers must be extended and jacked; just as if the
machine were on a job site.
If you are not an operator, have the operator set up
the machine for you. The need to repair the machine does not qualify you to oper-
ate the machine.
15.5
Electrocution hazard! If it is necessary to unfold the placing
boom to do maintenance work, you must watch for overhead power lines. You
must maintain a minimum clearance of 20 feet (6 meters) between the power line
and any part of the unit (50 feet (15 meters) for lines above 350 Kv). See Figure
71.
15.6
Falling hazard! If you cannot work at ground level, you must
find and use a suitable work platform, a tie-off harness system, or otherwise
secure yourself from falling.
15.7
If maintenance work requires that you use a crane, hoist, fork
truck, or similar machine, read and understand the safety regulations for that
equipment. Remember,
the boom may not be used as a hoist or crane! (See Fig-
ure 72.)
