  • Page 7: Safety Instructions

    It is always the owner's responsibility to comply with all applicable federal, state and local laws, rules and regulations regarding the ownership, operation and towing of your Wood-Mizer sawmill. All Wood-Mizer mill owners are encouraged to become thoroughly familiar with these applicable laws and comply with them fully while using or towing the mill.
  • Page 8 Safety Safety Instructions WEAR SAFETY CLOTHING WARNING! Secure all loose clothing and jewelry before operating the sawmill. Failure to do so may result in serious injury or death. WARNING! Always wear gloves and eye protection when handling bandsaw blades. Changing blades is safest when done by one per- son! Keep all other persons away from area when coiling, carrying or changing a blade.
  • Page 9 Safety Safety Instructions HANDLE FUEL/LUBRICANTS SAFELY DANGER! Due to the flammable nature of fuel and oil, never smoke, weld, grind or allow sparks near your engine or storage tanks, especially during times of fueling. DANGER! Never allow fuel to spill on a hot engine during fueling operations or otherwise.
  • Page 10 Safety Safety Instructions USE CAUTION WHEN WORKING WITH BATTERIES (GAS & DIESEL SAWMILLS ONLY) DANGER! Batteries expel explosive gases. Keep sparks, flames, burning cigarettes, or other ignition sources away at all times. Always wear safety goggles and a face shield when working near batteries.
  • Page 11 Safety Safety Instructions CAUTIONS FOR SAWMILL SETUP WARNING! Do not set up the mill on ground with more than a 10 degree incline. If setup on an incline is necessary, put blocks under one side of the mill or dig out areas for the outrigger legs to keep mill level.
  • Page 12 Safety Safety Instructions CHECK SAWMILL BEFORE OPERATION DANGER! Make sure all guards and covers are in place and secured before operating or towing the sawmill. Failure to do so may result in serious injury. Be sure the blade housing and pulley covers are closed (i.e. the safety switches located on them are engaged).
  • Page 13 Safety Safety Instructions KEEP HANDS AWAY DANGER! Always shut off the sawmill engine before changing the blade. Failure to do so will result in serious injury. DANGER! Engine components can become very hot during opera- tion. Avoid contact with any part of a hot engine. The exhaust com- ponents of your engine are especially hot during and following operation.
  • Page 14 Safety Safety Instructions CAUTIONS FOR GAS OR DIESEL ENGINE OPERATION DANGER! Operate your engine/machine only in well venti- lated areas. The exhaust gases of your engine can cause nausea, delirium and potentially death unless adequate ventilation is present. DANGER! Never operate an engine with a fuel or oil leak. The leaking fuel or oil could potentially come in contact with hot surfaces and ignite into flames.
  • Page 15 Safety Safety Instructions USE PROPER PROCEDURE WHEN CONDUCTING ELECTRICAL SAFETY CHECKS AND MAINTENANCE DANGER! Make sure all electrical installation, service and/or maintenance work is performed by a qualified electrician and is in accordance with applicable electrical codes. DANGER! Hazardous voltage inside the electric boxes and at the motor can cause shock, burns, or death.
  • Page 16 Safety Safety Instructions KEEP SAFETY LABELS IN GOOD CONDITION IMPORTANT! Always be sure that all safety decals are clean and readable.
