3.11 Up/Down System
1. Adjust the up/down chain tension as needed. Measure chain tension with the cutting head all the way
to the top of the vertical mast. Secure the carriage with a chain at the top, or shim it underneath.
Using the adjustment nut shown in Figure 3-7, adjust the chain tension so that there is 1” (2.5 cm)
deflection in the center of the chain with a 5 lbs. (2.3 KG) deflection force.
WARNING! Always secure the cutting head with a chain or a brace
before adjusting or inspecting the up/down system. The cutting head
may fall, causing severe injury or death.
See Figure 3-7. Use the adjustment nut shown below to tension the chain.
2. Every 500 hours check the up/down chain and chain brackets for wear.
WARNING! If you noticed the up/down chain or chain brackets wear,
immediately stop the work and contact Wood-Mizer Customer Service.
Failure to do so will result in serious injury or death.
3. Adjust the up/down gear belt tension as needed.
WARNING! Before adjusting, always remove the key from the key
switch. Failure to do so may result in serious injury.
