Maintenance
6. Carefully remove the plugs from the hydraulic drain
hose and open the valve over the container.
7. Allow all the hydraulic oil to drain from the hydraulic
tank into the container.
8. Reinstall the hydraulic oil drain plug on the drain
hose and tighten securely. Close valve.
9. Change the hydraulic oil lter by turning lter
counterclockwise, then replace with new lter
turning clockwise until snug (by hand only). (Figure
5-25)
10. Carefully remove the cloth from the hydraulic oil
reservoir ll tube opening.
11. Remove the strainer. Replace if necessary.
DO NOT ll the hydraulic oil reservoir
with new hydraulic oil until the strainer inside the ll
cap has been serviced.
12. Fill the hydraulic oil tank with ltered hydraulic oil.
The cold oil level should be about 1/2-inch below the
ll level black line on the sight gauge. (Figure 5-20)
13. Reinstall the hydraulic oil strainer ller cap and
tighten the three wing nuts securely.
14. Start the engine and check the hydraulic system for
possible leaks.
Stop the engine immediately if any
hydraulic leak is noted. DO NOT start the engine until
any problem noted has been corrected.
ELECTRICAL SYSTEM
The electrical system is a 12-volt negative ground
system. Connect the positive (+) cable to the positive
(+) post of the battery. Connect the ground cable to
the negative (-) post of the battery. It is advisable to
disconnect the negative (-) cable rst and connect it last.
Reversed polarity can damage the electrical system.
(Figure 5-26)
Fire and Explosion Hazard! Always
observe battery polarity when connecting a battery
charger or jumper cables to the battery: negative (-)
to negative (-), positive (+) to positive (+). Failure to
do so can produce sparks.
When connecting a booster battery, connect one end
of the rst jumper cable to the positive (+) terminal of
the dead battery and the other end to the positive (+)
terminal of the booster battery. Connect one end of the
second jumper cable to the negative (-) terminal of the
booster battery and the other end to the frame of the
paver with the dead battery.
Fire and Explosion Hazard! Be sure
that the battery charger is in the OFF position before
connecting it to the battery.
Be sure to keep the battery fully charged during cold
weather to keep it from freezing. Freezing weather has
little effect on a fully-charged battery.

ALWAYS turn the master battery
switch off when working on the electrical system
or welding anywhere on the machine. Damage to
electrical components could result.
DO NOT pressure-wash electrical
components, especially around the generator.
Protect electrical components when washing paver.
