Your 450 saw has been shipped from the factory thoroughly 

inspected. Only minimal assembly is required to start using the 

saw. Remove the saw from the container using proper lifting 

techniques. Discard or recycle the packing material per your 

regional laws. In your container will be the 450 saw, blade 

shaft wrench, an owner’s manual, an engine owner’s manual, 

a part list, a warranty card, a joint protector sample pack, a 

diamond blade, a skid plate, and a ramp for unloading the saw.
