IMPORTANT: DO NOT OVERFILL! lf the oil
level is too high, oil foaming, excessively high oil
temperature and oil leakage at the seal could
result.
4. Start and run the machine long enough for the oil
to circulate and warm slightly. Recheck the level with
the dipstick.
CHANGE 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 out the cooling fins in the radiator
with water pressure or steam.
NOTE: When cold weather is expected, fill the
cooling system with a 50-50% mixture of water
and ethylene glycol anti-freeze.
4. Inspect the radiator cap seal before installing it.
Replace it if it appears defective. The 10 PSI (69 kPa)
pressure cap and engine thermostat work in conjunc-
tion with each other to maintain proper engine cooling.
NOTE: Check the engine temperature lamp
every minute or two after coolant has been
changed. Air pockets can form, and it may be nec-
essary to refill the cooling system after a short
period of use, as the air will naturally bleed out of
the system.
maintaining a light film of grease on the pad tracking
areas of the boom sections. An exception would be if a
boom section has been replaced.
Visually check for loose pad bolts. The bolts are
torqued to 30 ft-lb (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. 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).
NOTE: Perform all other service requirements
up to this point, as well as the following.
CHANGE TRANSMISSION OIL
and FILTER
Operate the machine long enough to warm up the
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 out 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. Spin
tighten.
3. Refill the transmission with new oil as shown in
the LUBRICATION chapter of this manual.
Service Every 1000 Hours
WARNING
Remove the radiator cap only when the engine
is cool, or painful burns could result.

WARNING
Failure to maintain proper slide pad clearance
and thickness could cause damage to the
boom and boom chains, resulting in sudden
boom failure.
