Sinoboom 1323RD - Inspect Hydraulic Oil Level; Inspecting Engine Oil Level

PRE-OPERATION INSPECTION
1323RD&1623RD Operation Manual 5-3 © Mar. 2022
NOTICE
If the machine has to be inspected with platform
raised, please be sure the safety arm is properly set
up.
INSPECT HYDRAULIC OIL
LEVEL
Ensuring appropriate hydraulic oil level is vital to proper
operation of the machine. If too high, the oil will spill out
from the oil tank during machine operation, if too low,
the oil pump will suction air and damage hydraulic
components. Performing daily inspection of the
hydraulic oil level will help you determine if a problem
exists in the hydraulic system.
Perform the following procedure with the platform
retracted:
1. Visually inspect on the hydraulic tank side to be
sure the hydraulic oil level is whithin the marking
range of sight gauge.
Figure 5-1
2. Ensure the tank body and ports are free of leakage.
3. Add hydraulic oil as needed. Never overfill the tank.

cannot be mixed.
INSPECTING ENGINE OIL
LEVEL
NOTICE
Turn off the engine before inspection.
The appropriate engine oil 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 engine oil level which may indicate a system
distress with the engine.
1. Turn the ground/platform select switch to ground
control.
2. Pull out the emergency stop button at ground
controls to ON position.
3. Move the engine preheat switch and idle for 2
minutes.
4. Switch off the engine, and 5 minutes later open the
engine cover.
5. Remove the engine dipstick to inpsect the engine
oil level.
6. The engine oil level should be between the FULL
and ADD marks.
7. Add engine oil as needed. Do not overfill. It is
recommended to use engine oil equivalent to or
higher than CH-4 with viscosity grade of 15W-40.
