Safety Practices
2. Clearances
Look out for and avoid other personnel, machinery and vehicles in the area. Use
a spotter if you do not have a clear view of conditions that affect clearances.
Travel with the boom fully retracted and lowered as far as possible while still
maintaining enough ground clearance for conditions.
Always check boom clearances carefully before driving underneath door
openings, bridges, etc.
Always check for power lines when raising the boom. Beware of overhead wires.
Contact with electrical power lines can result in electrocution. See Electrocution
Hazards.
3. Visual Obstruction
Dust, smoke, fog, etc. can decrease vision and cause an accident. Always stop
or slow the vehicle until the obstruction clears and the worksite is visible again.
Have a lookout person assist you.
Where the load will obstruct the operatorís vision, it is recommended that the
vehicle be operated in REVERSE, looking backwards in the direction of travel.
Travel at a slower speed and get someone to direct you.
4. Underground Hazards
Know the location of all underground hazards before operating this vehicle in a
new area or worksite. Electrical cables, gas and water pipes, sewer, or other
underground objects can cause death or serious personal injury. Contact your
local underground utility service or diggers hotline to mark all underground
hazards.
5. Electrocution Hazards
NEVER operate this vehicle in an area where overhead power lines, overhead
or underground cables, or other power sources may exist without first
requesting that the appropriate power or utility company de-energize the lines,
or take other suitable precautions.
