TROUBLESHOOTING
LOWERING THE BOOM TO THE GROUND
LOWERING THE BOOM TO
THE GROUND
If the hoe attachment must be lowered to the
ground while the engine is stopped, use the
following procedure.
Procedure 1
(machines with an accumulator)
Perform this operation within 10 minutes
after the engine stopping.
1. Sit at the operator’s seat.
2. Turn the starter switch to the ON position.
3. Lower the safety lock lever to the unlock
position
4. Slowly push the operating lever forward to
lower the boom.
Procedure 2
(machines without an accumulator)
This operation is dangerous and requires
experience. Ask your sales or service dealer
for it.
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine and the hydraulic system
and many other parts of the machine
are hot immediately after the engine is
stopped. Touching these parts will
cause burns.
· The hydraulic oil is also hot and under
high pressure immediately after the
engine is stopped.
Be careful when loosening the caps or
plugs. Working on the machine under
these conditions could result in burns
or injuries due to the hot oil spurting
out.
• Keep away from the working area when
the hoe attachment is lowered. You may
be hit by dirt falling out of the bucket or
the hoe attachment as it drops.
• Slowly turn the hose nut and lower the
boom at a slow pace.
• Do not loosen or remove the hoses not
located in the specified places. Oil may
spurt out if wrongly handled.
1. Place a pan under the hose to catch the
waste oil.
2. Hold the hose fitting (1) with a wrench and
slowly loosen the hose nut (2) with another
wrench.
3. The oil in the boom cylinder is drained and
the hoe attachment is lowered.
4. After the hoe attachment is lowered to the
ground, check the safety and stability of
the machine.
5. Hold the hose fitting (1) with a wrench and
tighten the hose nut (2) with another
wrench.
