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 the up/down chain. 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.
Adjust the up/down gear belt tension as needed (option).
WARNING!
Before adjusting, always remove the key from
the key switch. Failure to do so may result in serious injury.
