V-BELT
The BD10 Trim Saw blade arbor is powered by an AX-27 rubber V-belt from the electric motor. The V-belt is
correctly tensioned at the factory. However, if it is necessary to service the belt, unplug the BD10 Trim Saw
from its power source and remove the fasteners which secure the belt guard housing (Fig. 28). If the belt
tension should become too loose, poor sawing performance or slipping will result. The belt tension should be
checked periodically by removing the guard and depressing the belt in the middle between the motor and blade
pulleys (Fig. 29).
There should be 1/2" of deflection once the belt is pushed down. If the belt is too tight (i.e. no deflection) the
electric motor and blade arbor bearings may be overheated and wear out prematurely or the motor may shut off
due to overheating. Belt tension can be adjusted by loosening the jam nut and then adjusting the hex head bolt
in the center top of the motor mount plate (Fig. 30). Be sure to replace and attach the belt guard.
POWER FEED SYSTEM AND VISE
The power feed system utilizes a AC gear motor mounted inside of the rectangular box attached to the table of
the BD10 Trim Saw. There is no need to service or lubricate the power feed motor unless the motor fails and
the screw feed rod fails to rotate when the feed is engaged. If the set screw that fastens the power feed motor
to the feed rod loosens during use or shipping, the rod will not rotate and move the vise toward the blade. This
rod set screw can be tightened with a US standard Allen/hex wrench should it loosen.
