5.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).
6.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
7.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.
8.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).
CAUTION - Overfilling the Hydraulic Oil Resevoir
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.
9.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

Battery Maitenance
CAUTION - Battery Maintenance Safety
Wear safety glasses or face mask, protective clothes, and rubber gloves when working with battery.
1.Check the battery terminals periodically to ensure that they are in good condition.
2.Use wire brush or sand paper to clean the battery terminals.
3.Check battery for cracks or any other damage. If white pattern appears inside the battery or paste has accumulated at the bottom, replace the battery.
4.If the machine will not be in operation for a long period of time, store in cool dry place and check the battery charge level every month to maintain the performance of the battery.
Battery Cable Connection
1.Take off the battery cover by removing the M6 nuts (Figure 30).
2.When removing cable, disconnect the ground side (normally negative) first (Figure 30).
3.When installing cable connect the ground side (normally negative) last.
