SOLUTION
9a. Depress each of the overload
buttons 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.35 hydraulic maintenance.)
11c. Adjust accordingly.
12. Select "Manual" mode.
13. Readjust 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.
