Page 22 BB4500-BB5000 Operating Manual
Both motors have a four-speed gearbox for maximum versatility. Table 2-10 speci-
fies the operating range for each gear.
CAUTION
Before shifting gears, remove the cutting load from the motor and stop
the motor rotation. Shifting gears while the machine is under load could
damage the motor and gearbox components.
CLIMAX’s portable machine tools require a three-wire extension cord. Extension
cords of inadequate wire size may cause a significant drop in mains voltage with a
consequent loss of power.
As the distance from the supply outlet increases, heavier gauge extension cords are
required (see Table 2-11).
