SAFETY DECALS
Safety decals are attached to the machine to alert the operator
or maintenance person about potential hazards, the
consequences of potential injury, and instructions and/or actions
required to avoid the hazard. The location of the safety decals
and the description of the decals are reviewed in the following
section. Please become familiarized with all safety decals and
their messages.
Make sure that all the safety decals are in their correct location
and legible. Clean or replace the safety decals if they are
damaged, missing, or the texts and pictorials are not legible.
When you clean the safety decals, use a soft cloth, water, and
soap. Do not use solvent, gasoline, or other harsh chemicals to
clean the safety decals because this could loosen the adhesive
that secures the decals to the machine. Remember, if a safety
decal is attached to a part that is replaced, install a new safety
decal on the replacement part.
This machine uses safety decals with and without text. The type
and number of safety decals can vary depending upon
geographical regions and machine models.
Safety Decals With Text
