SOLUTION
9a. Depress each of the overload
b
uttons located in the electrical box.
Depressing one button at a time and
trying to start the saw will indicate
which motor was overloaded.
9b. Replace the fuse with a 5 Amp
250 Volt AG1 type fuse. Random
blowouts may occur but a quickly
repeated blow-out points to an internal
wiring fault.
10. Reload with stock or remount
blade.
11a. Stop immediately; reverse any
two of the 3 phase connections.
11b. Stop immediately, add hydraulic
oil. (See pg.3.28 hydraulic mainte-
nance.)
11c. Adjust accordingly.
12. Select "Manual" mode.
13. Adjust head up limit switch
bracket.
14a. In case of head function non-
response check the related limit
switches. Limit switch levers should
operate freely and emit an audible click
on both depress and release. If not
replace the switch. To check the switch
unit itself remove the switch lid and wire
together the two terminals closest to the
wiring port. If function now responds to
manual switch replace limit switch. If
function still does not respond then.
Open panel door to gain access to
vaves. Remove coil retaining nut and
withdraw problem related coil, replace it
with any other coil from the group. If the
problem remains it requires the
attention of a qualified service person.
PROBABLE CAUSE
9a. Motor overload has tripped.
9b. Control circuit fuse has blown.
10. On machines so equipped,
the out-of-stock or blade breakage limit
switch has been tripped.
11a. If blade wheels run clockwise,
wrong phase order in power connection
to saw.
11b. If pump is noisy cause may be low
hydraulic oil level.
11c. Pump-motor coupling has
separated.
12. Mode Selector switch is in the
"Neutral" position.
13. Head up limit is set fully down.
14a. Observe pilot light(s) on relevant
valve.If pilot light related to inoperative
function fails to light, problem is
electrical.
PROBLEM
9. Saw will not start.
10.Saw starts but will not
run after Start button has
been released.
11.Saw starts but no
hydraulic functions.
12.Saw starts but only front
vise functions.
In Manual Mode
13.Head will not rise.
14.No individual function
will respond to its manual
control switch.
