transmission oil. Shut down the engine. Access to filter
and drain plug is from underneath the machine.
Proceed as follows:
1. Remove the drain plug and drain old oil. Replace
the drain plug.
IMPORTANT: DO NOT discharge oil onto
ground. Catch and dispose of per local waste dis-
posal regulations.
2. Remove and discard the oil filter. Wipe the sealing
surface on the transmission with a clean cloth.
Apply a thin coat of clean oil to the new oil filter
gasket. Hand tighten.
3. Refill the transmission with new oil as shown in
the LUBRICATION chapter of this manual.
IMPORTANT: DO NOT OVERFILL! lf the oil
level is too high, oil foaming, excessively high oil
temperature and oil leakage at the seals could
result.
4. Start and run the machine long enough for the oil
to circulate and warm slightly. Recheck the level
with the dipstick.
CHANGING RADIATOR COOLANT
Drain, flush and refill the cooling system as follows:
IMPORTANT: DO NOT discharge coolant onto
ground. Catch and dispose of per local waste dis-
posal regulations.
1. Loosen the radiator cap to its stop. This will
release any system pressure. Remove the cap when
all pressure is bled off.
2. Open the radiator drain cock. Remove the water
jacket drain plug from the engine block. When all
coolant is drained, flush the system with clean
fresh water. Allow the flush to drain completely.
3. Replace all drain plugs and tighten the radiator
drain cock. Clean the cooling fins in the radiator
with water pressure or steam.
Visually check for loose pad bolts. The bolts are
torqued to 30 ft.-lbs. (40 Nm). If the bolts are re-
torqued at any time, Loctite
thread lock must be re-
applied to the bolts.
If the boom starts to chatter under load, grease the slide
pads and wipe off the excess. If a top or side slide pad
shows excessive wear, loosen bolts and insert shims to
each side or top and bottom for even distribution of
clearance. Re-apply Loctite
®
thread lock to the bolts
and re-torque to 30 ft.-lbs. (40 Nm). Bottom slide pads
should be replaced when the thickness is worn down to
3/8” (9.5 mm).
