Warning
Perform a pre-operation inspection and func-
tional tests at the beginning of each work
shift. Perform the pre-operation inspection
first. DO NOT perform the pre-operation
inspection with the engine running or hot.
Contact with moving or heated parts could cause death or
serious injury.
Perform the pre-operation inspection and
functional tests in an open area and away
from any other obstacles or equipment.
Inspections and functional tests may require
assistance. Keep the assistant visible and a
safe distance from the telehandler to prevent death or se-
rious injury.
Remove telehandler from service and place
“Do Not Operate” tags on the starter switch
and steering wheel if anything is found to be
in need of repair or maintenance, defective,
or unsafe in any way.
The safety, efficiency, and service life of your telehandler
will be increased by performing functional tests at the
beginning of each shift. If any of the items in the functional
tests are not operating properly or within set tolerances,
stop the telehandler, follow proper shut down procedures,
tag the telehandler with “Do Not Operate” tags, and have a
qualified mechanic service or repair the telehandler before
placing it into service again.
