OPERATION & MAINTENANCE MANUAL STE35SR
Oil Level of Hydraulic: Check or Add
After stopping the engine, the parts and hydraulic oil are still at high temperature, which may
cause burns. Therefore, wait until the temperature drops before starting work.
1. If the working device is not in the state shown in the
figure on the right, start the engine and run the engine
at a low idle speed. Fully retract the arm and bucket
cylinder rod, then lower the boom, adjust the bucket
teeth to the ground contact position, and turn off the
engine.
2. Within 15 seconds after turning off the engine, turn
the safety lock switch to the ON position, and operate
the joystick (working device, walking) in each direction to release the internal pressure.
3. Check the level gauge on the hydraulic oil tank. The
oil level must be between the marks on the level
gauge, otherwise hydraulic oil needs to be filled.
The refueling steps are as follows:
1. Use the key to open the fuel cap lock;
2. Unscrew the fuel filler bolt;
3. Add hydraulic oil and check the level gauge again;
4. Tighten the fuel filler bolt and lock the fuel filler lock.
Air Cleaner Dust Indicator (optional): Check
IMPORTANCE
Only when the pressure difference indicator (1)
pops out and the red mark is visible. The air filter
needs to be cleaned, otherwise there is no need
to clean the air filter element.
If the air filter element is cleaned frequently
before the pressure difference indicator has not
warned, the performance of the air filter will not
be fully exerted, and its filtering effect will be
deteriorated.
In addition, the dirt attached to the filter element
during cleaning will frequently fall to the inner
filter element side and be sucked into the engine,
causing engine wear.
When the pressure difference indicator (1) pops up and shows red, clean or replace the filter
element immediately.
For details about cleaning the filter element, see "Air Filter-Inspection/Cleaning/Replacement"
in Inspection and Maintenance.
