I have informed the Purchaser of this product of Warranty terms, provisions, and procedures that are applicable, reviewed the
contents of the Operator's Manual including safety equipment, safe operation, and maintenance, reviewed the Safety Signs on
implement (and tractor if possible), and Purchaser's responsibility to train his operators in safe operation.
MOWERS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be maintained in good repair and installed except
in areas where persons, vehicles, livestock, or other property will not be endangered by thrown objects and where such safety
equipment would prevent the mower's reasonable performance of its assigned task.
DRIVELINES: Make certain that all drivelines, gearbox, and other shields are in good repair and fastened securely in place to
prevent injuries from entanglement or thrown objects.
I have been instructed on the paragraphs above, received and have been instructed in the contents of the Operator's Manual including
safety signs, safety equipment, safe operation, maintenance, and the potential hazards of unauthorized alteration or modification of
the product. I have been informed of the warranty provisions and know that the warranty is not in effect until this form is received
by Alamo Group.
I understand the Mower Guarding statements above and the potential hazards of operating without such guards. I understand that the
operator is responsible for the safety of others in the area. I have examined the product and accept it as being complete and in
satisfactory condition with all required guards.
