What you need to know:
The chipper is serious equipment, wear safety gear: sturdy footwear, ear and eye protection, gloves and chaps if you have them.
Hardhats will be provided if you don't have them.
Stack piles neatly and face all limb "butts" OUT- for easy grabbing and feeding
Wear "cuffless gloves" Cuffs can snag branches while feeding the chipper
Arrive rested and DRINK plenty of water.
Take breaks and rest if you become winded.
Keep work area clean!
Never approach chipper without an attendant, and their permission.
Feed chipper from side of hopper- NOT the center.
Don't hurry- keep an orderly line and feed the hopper when motioned to.
Always watch for traffic if you're on a thoroughfare- they may be gawking- stay safe
