PREVENTATIVE MAINTENANCE
DO NOT fill the fuel tank to capacity. Allow room for fuel
expansion.
Tighten the fuel cap securely. If the cap is lost, replace only
with original equipment.
Check the Engine Crankcase Oil Level
1. Level the crane, engage the parking brake and shut off
the engine.
2. Lift the engine compartment cover and support in place
using the furnished prop rod.
3. Remove the engine oil dipstick and check oil level. Oil
should be visible within the crosshatched mark area on
the dipstick.
4. If the oil is low, add recommended oil to bring the level
up to the crosshatch area of the dipstick. When full,
install the dipstick and close the engine compartment
cover.
Check the Transmission Oil Level
1. Check the oil level when the oil is cold. Level the crane,
engage the parking brake and shut off the engine.
2. Lift the engine compartment cover and support in place
using the furnished prop rod. Remove the dipstick
(Figure 5-18) and check the oil level. Oil should be
visible on the dipstick between the minimum and
maximum marks with the oil cold.
3. If oil is low, add recommended oil to bring the level
between the marks. DO NOT OVERFILL. Install the
dipstick. Close the cover.

Check Engine Coolant Level
NEVER remove the radiator cap while the cooling system is
hot. Check coolant level only when the coolant temperature
is below 120° F (50° C). The system is under pressure and
the coolant can cause severe burns or eye injury. Wear
protective clothing and safety glasses. Always turn the cap
slowly to the first stop and allow the pressure to escape
before removing the cap completely.
1. Level the crane, engage the parking brake and shut off
the engine.
2. Check that the overflow bottle (Figure 5-19) is at least
half full. If coolant is low, fill the overflow bottle half way
with a 50/50 mixture of glycol antifreeze and water. Do
not add only water as this could cause rust to form in the
radiator and engine.
3. If the bottle is empty, BE SURE THE ENGINE IS COOL
to below 120° F (50° C), then slowly loosen the radiator
cap to the first stop. Allow all pressure to release.
Remove the radiator cap and check the fluid level.
Coolant should be visible in the radiator.
4. If level is low, add a 50/50 mixture of glycol antifreeze
and water, do not add only water as this could cause rust
to form in the radiator and engine.
