Make sure that hand pump is filled with hydraulic oil to the
specified level. Excessive oil may hinder bleed valve function,
resulting in poor reverse performance.
CAUTION -
Overfilling the Hydraulic Oil
Reservoir
6.
Filling the reverse travel circuit with oil
.
a. With the travel lever pushed forward (hydraulic circuit is
connected with reverse travel circuit), add oil into pump
and remove bleed plug of vibrator cylinder (opposite of
belt cover side). In a few seconds, oil will come out of
bleed plug.
b. When aeration disappears, reinstall the plug tightly.
c. Move the travel lever slowly until aeration in the hand
pump disappears (about 10 to 15 times).
7. When the aeration in the pump disappears, with the travel
lever pushed forward, reinstall the valve. Be careful not to
drop the packing into pump. The bleeding valve tightening
torque is 450 to 500 kg-gm.
8. After installing the bleed valve, moving the travel lever all the
way to reverse causes excess oil to be discharged into pump.
If valve fails to activate, aeration still remains in the circuit.
With the bleed valve removed, operate travel lever again to
bleed. If valve is activated, move the travel lever forward to
activate the valve inside spool before moving it to reverse to
activate the bleed valve. Repeat 3 to 4 times.
9. After making sure that the hydraulic oil in the pump is at the
specified level, reinstall the reservoir cover. Coat both sides
of packing with liquid packing (such as Threebond #1215).
10.After adding oil and reinstalling the reservoir cover, operate
the travel lever to make sure of the following:
a.
spool valve:
when pushed forward, resistance is felt in
two-stage motion.
Checking The Fuel
1. Remove the fuel cap located on top of fuel tank.
2. Visually inspect to see if fuel level is low. If fuel is low, replenish
with diesel fuel (Figure 23).
3. When refueling, be sure to use a strainer for filtration. DO NOT
top-off fuel. Wipe up any spilled fuel.

If fuel spillage occurs, wipe up the spilled fuel completely to
prevent fire hazards.
NEVER!

compactor.
Explosive Fuel
Diesel fuel is highly flammable and can be dangerous if
mishandled. DO NOT smoke while refueling. DO NOT attempt
to refuel the compactor if the engine is
hot!
