WARRANTY & SERVICE

Warranties

Bigger Boyz Toyz offer a 1-year parts warranty on all products used for domestic use from the date of purchase. 
For all commercial use, a 3-month parts warranty period applies, unless specified in the item listing. All conditions 
below are based upon the product being faulty or not performing as described. In the instance where a return 
is required, the purchaser is liable for any shipping cost. Warranties will only be determined by a Bigger Boyz 
Toyz Technician upon inspection.

Warranties do not cover accidents, misuse, neglect, natural disaster or act of God or other external causes, or 
damage caused by operating the equipment in a manner that is not described in the instructions. 

Our products come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled 
to a replacement or refund for a major failure and for compensation for any other reasonably foreseeable loss or 
damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality 
and the failure does not amount to a major failure.

Parts purchases, consumable components and accessories such as chains, carry bags, batteries, hoses, grinding 
discs, covers, belts, cable, wheels and blades are not covered by standard warranty.
