Safety
Use Care on Loose Support
Working heavy loads over loose, soft ground or uneven, broken
terrain can cause dangerous side load conditions and possible
tipover and injury. Travel without a load or balanced load may
also be hazardous.
If temperatures are changing, be cautious of dark and wet
patches when working or traveling over frozen ground. Stay
away from ditches, overhangs and all other weak support
surfaces. Halt work and install support mats or blocking if work is
required in an area of poor support.
Use Solid Support Blocking
Never rely on lift jacks or other inadequate supports when work
is being done. Block wheels fore and aft to prevent any
movement.
Digging Beneath Overhangs
Digging beneath an overhang is dangerous. Overhang could
collapse on top of operator and cause serious injury or death.
Go on to another digging area before steep overhangs are
formed. Know height and reach limits of wheel loader and plan
ahead while working. Park wheel loader away from overhangs
before work shut down.
Digging Beneath Wheel Loader
Digging beneath wheel loader is dangerous. Earth beneath
could collapse. This could cause wheel loader to tip, which could
cause serious injury or death to operator. Working around deep
pits, trenching or along high walls may require support blocks,
especially after heavy rainfalls or during spring thaws.
