M A E D A Mini-Crawler Crane Section 5 – INSPECTION
1/2019 MC285C-3 5-19
Pre-Start Inspection
Perform the following inspections daily before
starting the engine.
WARNING! Equipment Hazard. Failure to
perform these inspections may result in
machine damage and/or personal injury.
Check / Add Engine Coolant
Before checking or adding coolant, read the
maintenance precautions in “Handling and
Service of Engine Coolant” on page 5-6.
WARNING! The following safety messages
address a potential Burn Hazard:
• Relieve internal pressure by slowly rotating
the radiator cap during removal.
• Make sure the radiator cap is closed
properly after checking or adding coolant.
• Never check or add coolant with the radiator
cap removed. Always check and add in the
reserve tank.
• When filling the radiator, do not overfill, as
this may cause the coolant to gush from the
cooling system during machine operation.
NOTICE: Low coolant level may cause
overheating and corrosion attributed to aeration.
Check the ratio of the coolant frequently using a
coolant tester. The mixing proportion of coolant
varies with outside air temperature.
1. Place the machine on a level surface.
2. Check the coolant level in the reserve tank (1)
through the inspection window (A) located at
the front side of the left machinery cover. It
must be between “LOW” and “FULL”.
Fig. 5-9
3. If the coolant level is lower than the “LOW”
level, use the following procedure to refill
coolant.
a. See “Removing Machinery Cover” on
page 5-14 and remove the machinery
cover.
b. Remove the cap (2) of the reserve tank
(1) and fill coolant from the filler opening
to the level “FULL”.
c. After refilling coolant, securely install the
cap (2) of the reserve tank (1).
d. See “Installing Machinery Cover” on
page 5-14 and install the machinery
cover.
Fig. 5-10
4. When the reserve tank is empty, perform the
following procedures.
a. See “Removing Machinery Cover” on
page 5-14 and remove the machinery
cover.
b. Remove the radiator cap (3) and check the
radiator for coolant level.
c. When it is too low, check the radiator,
radiator hose and each part of the engine
for water leakage.
d. Add water through the water filler of the
radiator and securely tighten the radiator
cap.
e. Remove the cap of the reserve tank and
add water up to the FULL level through the
water filler.
f. After the replenishment of coolant,
securely mount the cap of the reserve
tank.
g. See “Installing Machinery Cover” on page
5-14 and install the machinery cover.
