3.8 Blade Tensioner
1. Lubricate the chrome rods of the tensioner system with a heavy duty teflon spray lubricant, such
as Gunk L508, every fifty hours of operation.
2. Lubricate the tensioner screw handle with a NLGI No. 2 grade lithium grease as needed.
See Figure 3-4.
3. Add an Automatic Transmission Fluid (ATF) such as Dexron III ATF to the hydraulic blade ten-
sioner as needed.
See Figure 3-5. To add enough fluid to completely fill the tensioner block:
Remove the tensioner handle and ball. Remove the sawmill blade housing covers, blade
and idle-side blade wheel.
Push the idle-side shaft housing all the way in to collapse the rear tensioner piston and fully
extend the front piston. The front piston should reach the threaded area of the piston guide.
NOTE: If the hydraulic fluid level is extremely low, collapsing the rear piston may not fully
extend the front piston. If it does not, finish the fill procedure in its entirety and repeat. The
first pass should add enough fluid to allow the front piston to fully extend. The second pass
should add enough fluid to completely fill the block.
Locate the fill plug behind the tension gauge. Clean any dirt and debris from the plug area.
Use a 7/16” wrench to remove the plug, making sure to keep the plug o-ring with the plug.
