Changing the Radiator Fluid
Change the radiator fluid every 500 hours of operation,
or every two years (whichever comes first). DO NOT
drain the radiator fluid when hot.
1. Open the radiator door.
2. Place a drain pan under the radiator drain valve.
Figure 26: Drain Valve Wing Nut
3. Loosen the drain valve wing nut (below radiator
door) and drain the fluid completely. Dispose of the
used fluid according to city, state, and federal
regulations.
4. Tighten the drain valve wing nut to secure.
5. Open the air bleed valve wing nut (inside radiator
door, near top of door). Slowly remove the radiator
cap.
Note: Remove the radiator cap only when it
feels cool to the touch, and always open it slowly to
relieve any built up pressure
.

6. Add a 50/50 mix of water and anti-freeze through the
radiator fill port until it begins to leak out of the air
bleed valve.
7. Close the air bleed valve wing nut.
8. Add more radiator fluid through the fill port until the
fluid reaches the overflow hole inside the filler neck.
9. Replace the radiator cap and retighten to secure.
Hydraulic System
WARNING

Always place a piece of
cardboard or paper up against
hydraulic components, or use a
leak detection fluid to check for hydraulic fluid
leaks. Keep all body parts away from leaks
and/or areas that may eject hydraulic fluid.
Pressurized hydraulic fluid can penetrate the
skin, causing serious injuries. Seek medical
attention immediately!

Always make sure any hydraulic components
being serviced are not supporting the weight of
other saw components. If a particular
component is under pressure when
connections points are loosened, oil may spray
out forcefully.
Inspect all hydraulic hoses and fittings daily for leaks.
Remember to use cardboard or a piece of paper when
checking for leaks and replace damaged components
immediately.
Adding Fluid to the Hydraulic Lift Pump
Figure 28: Hydraulic Lift Pump
Check the fluid daily and add fluid to the pump as
necessary.
1. Lower the saw to level the frame.
2. Remove pump cover.
3. Remove the shorter hydraulic pump breather cap.
4. Add SAE15W-40 oil or an equivalent to just below
where the fill port extends into the hydraulic pump.
Do not overfill, as this will cause oil leakage through
the breather cap when raising the saw.
5. Replace the breather cap and retighten to secure.
