OPERATION OF THE ENGINE
STARTING WITH AN AUXILIARY BATTERY
To avoid personal injury or death:
A Battery gases can explode.
Do not smoke and keep sparks and flames
away.
A Do not start the engine with an auxiliary battery
if excavator battery is frozen.
A Do not connect the black jumper cable to the
negative (-) terminal of the excavator battery.
BObserve Following Guidelines when
Starting with an Auxiliary Battery
1. Bring the helping machine with the same battery
voltage as near as possible to the excavator.
THE MACHINES MUST NOT COME IN CONTACT
WITH EACH OTHER.
2. Bring the levers and pedal of both vehicles in the
neutral position and put the pilot control lock lever in
the "LOCKED" position.
3. Wear eye protection and rubber gloves.
4. Open the side cover. (See "Opening / closing of the
Side Cover" in "MAINTENANCE" section.)
5. Ensure the vent caps are securely in place (if
equipped).
6. Connect the terminal of the red jumper cable with the
plus (+) terminal of the low battery and connect the
other end of the cable to the plus (+) terminal of the
auxiliary battery.
7. Connect the black negative cable to the minus (-)
terminal of the auxiliary battery.
8. Connect the other end of the black cable (coming from
the auxiliary battery) to the excavator frame as far
away as possible from the low battery.
9. Start the engine of the helping machine and let it run
for a while. Start the excavator with the low battery.
10. Disconnect the jumper cables in the reverse sequence
(Steps 8, 7, 6).
11. Replace the vent caps.
(1) Low battery
(2) Jumper cables
(3) Auxiliary battery
A This excavator has a negative (-) ground 12 Volt
starting system.
A Use only the same voltage when using an auxiliary
battery.
A Using a higher voltage will cause serious damage to
the electrical system. When using an auxiliary battery,
only the compatible (same) voltage is permissible.
CHECK POINTS AFTER STARTING THE
ENGINE
After starting the engine, but before starting operation,
check the following points:
1. Put the throttle potentiometer in the middle between
"
" and "
" symbols and let the engine idle for
approx. five minutes. This allows the engine lubricant
to warm up and penetrate every part of the engine.
2. Once the engine has warmed up, check:
A the warning lamp "Engine oil pressure" has gone
out.
A the warning lamp "Battery charge" goes out when
engine speed is increased.
A the color of the exhaust is normal and no abnormal
noises or vibrations are heard or felt.
A no fluid is leaking from pipes or hoses.
C Should any following conditions occur, stop the
engine immediately.
A The engine rpm's increases or decreases suddenly.
A Sudden abnormal noises are heard.
A Exhaust is black.
A Warning lamp for engine oil lights up during operation.
A In these cases, the excavator must be checked and
serviced by your local the KUBOTA dealer.
