4.11 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 4-7, 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 4-7.
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.
