Be sure to observe and follow these instructions. DANGER! indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING! suggests a potentially hazardous situation which, if not avoided, could result in death or serious injury.

  • Page 6: Observe 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 7: Wear Safety Clothing

    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 8: Dispose Of Sawing By-Products Properly

    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 9 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 10 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 11: Check Sawmill Before Operation

    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 12: Keep Hands Away

    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 13 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 14 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 90: Section 7 Sawmill Alignment

    Routine Alignment Procedure SECTION 7 SAWMILL ALIGNMENT The Wood-Mizer sawmill is factory aligned. Two alignment procedures are available to realign the sawmill if necessary. The Routine Alignment instructions should be performed as necessary to solve sawing problems not related to blade performance. The Complete Alignment procedure should be performed approximately every 1500 hours of operation (sooner if you regularly transport the sawmill over rough terrain).
  • Page 91 Sawmill Alignment Routine Alignment Procedure Saw Head Tilt As the blade enters a wide log or cant, the outside of the saw head will drop down slightly. To compensate for the drop, the saw head is adjusted 1/16" (1.5 mm) higher at the out- side.
  • Page 92 Sawmill Alignment Routine Alignment Procedure See Figure 7-2. To adjust the saw head tilt, use the bolts located at the bottom of the saw head mast. Loosen the three sets of four retaining plate bolts. To raise the outside of the saw head, back the stop bolts out, then tighten the adjustment bolts.
  • Page 93 Sawmill Alignment Routine Alignment Procedure Blade Guide Arm Alignment The blade guide arm moves the outer blade guide in and out. If the arm becomes loose, the blade guide will not deflect the blade properly, causing inaccurate cuts. A loose blade guide arm can also cause blade vibration.
  • Page 94 Sawmill Alignment Routine Alignment Procedure After tightening the blade guide arm rollers, check that the arm is aligned properly. Standard Guides 3. With the arm adjusted 1/2" (15 mm) from fully closed, measure the distance between the blade guide roller flange and the back of the blade. If the sawmill is equipped with optional all-ceramic guides, measure from the back of the blade to the back roller.
  • Page 95 Sawmill Alignment Routine Alignment Procedure See Figure 7-5. Loosen the horizontal adjustment bolt jam nuts. To tilt the arm in toward the blade, loosen the rear bolt and tighten the front bolt. To tilt the arm out away from the blade, loosen the front bolt and tighten the rear bolt.
  • Page 96 Sawmill Alignment Routine Alignment Procedure See Figure 7-6. Measure from bottom of the blade guide mounting block to bed rail with arm open and closed 600025-2 FIG. 7-6 7. Adjust the blade guide arm to 1/2" (15 mm) from fully open. Measure the distance from the bottom of the blade guide mounting block to the bed rail.
  • Page 97 Sawmill Alignment Routine Alignment Procedure See Figure 7-7. Loosen the vertical adjustment bolt jam nuts.
