Barranca Diamond CAB COMBO WORKSHOP - Manual (Page 29)

ELECTRIC MOTOR
The Cab Combo Workshop is equipped with a 1/3 HP 1725 RPM single-phase 120 volt 60 Hz 8 amp
motor. The motor shaft has sealed ball bearings and requires no lubrication. The motor is protected
from thermal damage (overheating) with an automatic shut-off switch. If the motor overheats it will
automatically shut off and restart once its internal components cool down and the motor is restarted
manually (red button). Be sure to shut off the main motor by placing the switch lever to the OFF posi-
tion and disconnecting the power source. After allowing the motor to cool (2 to 3 hours), push the red
reset button on the side of the motor (fig. 66) and restart the unit by turning the switch to ON. If the
motor does not restart after a cool down period, remove the motor and have an authorized repair ser-
vice center inspect the motor. Barranca Diamond can refer you to an authorized motor repair service
center in your area.
Please note: On Cab Combo Workshops prior to serial number 850, the motors do not have a reset
switch. Therefore it is imperative that if the saw motor should stop during operation that the power to
the main motor be shut off by placing the toggle switch in the MIDDLE/OFF position as the motor will
restart automatically once cooled down.
DIAMOND BLADE
Periodically, the diamond blade on the Cab Combo Workshop will need to be sharpened or replaced.
A dull or “glazed over" diamond blade can stall and cause the motor to shut off and possibly damage
the blade or “dish" the core. Once the saw begins to labor or struggle to cut, try using a sharpening
stick (green or white silicon carbide material, 60 to 100 grit size) on the blade.
If no sharpening stick is available, use an abrasive material such as cinder block or brick to remove
the glazing over the diamonds on the edge of the blade. Do not oversharpen the blade.
Eventually all diamond blades wear out and must be replaced. New continuous rim diamond blades
(303 Pro) should be mounted on the blade arbor so that the arrow marked on the steel core is point-
ing in the direction of blade rotation. If the arrow cannot be found, use a hand lens or magnifying
glass on the blade edge, find the head and tail of any diamond and orient with the tail trailing behind.
For notched rim diamond blades (297 or 301 models), it does not matter which way the blade is orien-
tated on the arbor shaft.
