Checking Engine Coolant Level
• Never remove the radiator cap while the cooling system
is hot. Check coolant level only when the coolant
temperature is below 50°C (120°F). 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 6-20) 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
(Below 50° C [120° F]), 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.
NOTE: For more details on proper radiator checking and
maintenance procedures, refer to the engine
manual that comes with your crane.
Drain Water From Engine Fuel Filter
1. Shut off the engine and engage the parking brake.
2. Refer to the engine manual furnished with the crane and
follow the water draining instructions.
Checking Hydraulic Oil Level
If the hydraulic oil is constantly low, check for leaks in the
hydraulic system.
1. Be sure the boom is fully retracted and lowered and the
outriggers are retracted and up.
2. Park the crane on a level surface, engage the parking
brake and shut off the engine.
3. Visually check the oil level on the hydraulic oil level sight
gauge (Figure 6-21). The hydraulic oil should be 3 mm
(0.125 in) below the top of the sight gauge. If low, fill tank
with clean recommended hydraulic oil.
