V-BELT
The PF10 Trim Saw blade arbor is powered by an AX-24 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 PF10 Trim Saw
from its power source and remove the fasteners which secure the belt guard housing to the saw table and
motor. 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.

There should be 1/2" of deflection once the belt is pushed down (fig 25). 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 four mounting nuts (fig 26) attached
to the four studs welded to the rear of the oil reservoir and sliding the motor cradle base up or down to increase
or decrease belt tension. Be sure to adequately retighten the motor mount nuts and replace and attach the belt
guard to the saw table.
POWER FEED SYSTEM AND VISE
The power feed system utilizes a 4 RPM AC gear motor mounted inside of the rectangular box attached to
the front of the PF10 Trim Saw (fig 27). 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 (fig 28) 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.
