SECTION 2 - PRE-OPERATION AND INSPECTION
2.1 PRE-OPERATION CHECK AND INSPECTION
Note: Complete all required maintenance before operating unit.
FALL HAZARD. Use extreme caution when checking items beyond your normal
reach. Use an approved ladder.
The pre-operation check and inspection, performed at beginning of each work shift
or at each change of operator, should include the following:
1. Cleanliness - Check all surfaces for leakage (oil, fuel or battery uid) or foreign
objects. Report any leakage to the proper maintenance personnel.
2. Structure - Inspect the machine structure for dents, damage, weld or parent
metal cracks or other discrepancies.
3. Safety Decals Placards - Ensure all safety decals are legible and in place. Clean
or replace as required. See page 2-2 for details.
4. Operation and Safety Manual(s) - Operation & Safety Manual(s) are in cab.
5. Walk-Around Inspection - See page 2-4 for details.
6. Fluid Levels - Check uids, including fuel, hydraulic oil, engine oil, transmission
uid and coolant. When adding uids, refer to Section 6 - Maintenance and
Lubrication and Section 7 - Specications to determine proper type and intervals.
Before removing ller caps or ll plugs, wipe all dirt and grease away from the
ports. If dirt enters these ports, it can severely reduce component life.
7. Attachments/Accessories - Inspect all attachments for dents, damage, weld or
parent metal cracks or other discrepancies. Inspect tie-down straps for cuts, frays
or tears. Inspect chains for weld or parent metal cracks or other discrepancies.
8. Operational Check - Once the walk-around inspection is complete, perform a
warm-up and operational check (see page 2-7) of all systems in an area free of
overhead and ground level obstructions. See Section 3 - Controls and Indicators
for more specic operating instructions.
If your MPL-NG does not operate properly, immediately bring machine to a stop,
lower boom to ground and stop the engine. Determine cause and correct before
continued use.
