HP14
V-BELT MAINTENANCE
The HP14 Slab Saw blade arbor is powered by a v-belt from the motor attached to the rear of the oil reservoir.
The belt tension should be checked periodically. Belt tension should be such that 1/2" of deflection is measured
by finger touch. If the belt tension should become too loose, poor sawing performance, belt slipping and dam-
age may result. 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.
If it is necessary to service this belt, unplug the HP14 saw from its power source and remove the fasteners that
secure the belt guard housing to the saw table. Depress the belt in the middle between both the motor and
blade arbor pulleys to see if there is 1/2 inch of deflection once the belt is pushed down (Photo 14).
Belt tension can be adjusted by turning the hex head bolt to pivot motor base in or out (Photo 15). Loosen
locking nut. Turn bolt clockwise to increase belt tension. Or turn bolt counter-clockwise to loosen belt tension.
When correct tension is achieved, retighten locking nut. Be sure to replace and securely attach the belt guard.

POWER FEED SYSTEM AND VISE MAINTENANCE
The power feed system AC gear motor (6 RPM) is mounted inside of the rectangular box attached to the rear of
the HP14 slab saw (Photo 16).
The set screw that fastens the power feed motor to the stainless steel screw feed rod should be checked prior
to use to determine if it has loosened (Photo 17).

This rod set screw can be tightened with a US standard allen wrench. Periodically clean any build up of grime,
grit, metal or debris with a common industrial cleaning solvent (i.e.. WD-40 or ZEP orange) and clean the
threads with a toothbrush or wire brush. Periodically apply a thin coat of lubricating grease (wheel bearing or
lithium grease) to the 3/8-24 LH stainless steel threaded rod to prevent the threads from becoming prematurely
worn.
