Sinoboom TB24 Plus - Inspect Coolant Level（Water; Cooled Engine

MAINTENANCE PROCEDURES
TB24 Plus&26J Plus Maintenance Manual 5-9 © Jun 2022
1. Turn the ground/platform select switch to ground
control.
2. Pull out the emergency stop button at ground
controls to ON position.
3. Turn the key switch at ground controls to ON
position.
4. Move the engine start switch and idle it for 2
minutes.
5. Switch off the engine, and 5 minutes later open the
turntable cover on the right side.
6. Remove the engine dipstick to inspect the engine
oil level.
7. The engine oil level should be within the FULL and
ADD marks.
8. Add engine oil as needed. Do not overfill. It is
recommended to use engine oil equivalent to or
higher than CJ-4 with viscosity grade of 15W-40.
Table 5-6
VISCOSITY RECOMMENDED AMBIENT TEMP
0W-30 -35℃～0℃
5W-40 -25℃～30℃
15W-40 -15℃～40℃
20W-50 0℃～50℃
NOTICE
• The engine oil filled by the factory is generally CJ-
4 with viscosity 15W-40, suitable for regions with
ambient temperature range of 15℃～40℃. If the
operating ambient temperature is outside of the
range, please change the engine oil as
appropriate.
• The multi-grade engine oil can provide excellent
lubrication under high-temperature operating
condition, reduce the sediments, and improve the
engine low-temperature start performance and
durability. Also, the multi-grade engine oil plays
an important role in ensuring the machine
meeting the emission standards.
• Do not mix the engine oils of different grades.
• It is recommended that the sulphated ash content
not exceed 1%, otherwise it will damage the air
valve or piston, and lead to excessive
consumption of engine oil.
• The use of high-quality engine oil in conjunction
with suitable oil filter and replacement interval of
oil filter is very critical to maintaining engine
performance and extending service life. If the oil
or oil filter is not replaced as recommended, there
will be sediments, contaminants or wear incurred
which will shorten the engine service life.
A-9 Inspect Coolant Level（water-
cooled engine）
The appropriate coolant level is vital to maintaining the
engine performance and extending its service life,
otherwise it will damage the engine parts. Through the
daily check the inspector can know about the changes
on coolant level which may indicate a system distress
with the engine.
HIGH TEMPERATURE AND
PRESSURE HAZARDS
Before inspecting the coolant level,
allow the coolant to cool down to
room temperature, and slowly open
the cover to release the pressure.
