Stuck Starter Reminder
Too many starters end up at support for service or repair. All it takes is one Fnger
stuck too long on the start switch to burn out a good starter.
±ollow the word on Page 5-2 of TM
5-3805-280-10. That is, when you try to
start your vehicle’s engine in cold weather,
never keep the starter engaged for more
than 30 seconds. Then stop! Give the starter
at least two minutes to cool off before
trying again.
After an unsuccessful start, do not turn
the starter switch back to START until the
engine stops. That saves the starter and
flywheel teeth. If your excavator’s engine
won’t start in three tries, call it quits. Get
your mechanic to Fnd out what’s wrong.
Ether Canister Empty?
Operators, one reason your excavator
may be hard to start in cold weather is
an empty ether canister.
The starter system has a fuel canister
that automatically injects ether into
the engine when you push the starting
aid switch.
So when your excavator is hard to
start, chances are the ether canister is
empty. Have your mechanic replace it.
Not draining the separator leaves
water and crud in the fuel system. Then
the engine runs rough… or not at all.
Open the separator, located behind
the engine access door (curbside), by
turning its drain cock counterclockwise.
Push down on the press pump to get
water out of the separator.
Store drained fuel in an approved
hazardous waste container. Never dump
it down a drain or on the ground from
the separator’s drain hose.
If the fuel is clear, you’re OK. If the
fuel doesn’t run clear, close the valve
and report it to your mechanic.
HYEX…
Cold Weather
a hard-to-start
engine and cold
weather seem to
go hand-in-hand.
keep these pm
pointers in mind to get
rid of your hydraulic
excavator’s cold
weather jitters.
Prevent starter damage
Don’t crank on
starter for more than
30 seconds at a time!
Drain fuel/water separator to get
water and crud out of fuel system
Check ether canister
Cool nights cause
condensation to form in
the excavator’s fuel tank.
That means you operators
have to drain the fuel/
water separator before
the day’s run.
just can’t get
it going this
morning!!!

by the way, make sure
the dust cap is in
place on the starter
valve when a cylinder
is not installed.
