Worm Shaft and Pinion Gear Lubrication
The worm drive shaft and pinion gear lubrication box on the rear of the saw should be checked for
adequate grease lubrication periodically. Remove cover to check lubricant, remove the box by remov-
ing the four mounting screws that attach the box to the rear of the saw reservoir. Check the level of the
grease lubricant in the box by ensuring that gear box is filled so that at least 1/3 of the volume of the
box (up to 1 to 1 1/2 inches from bottom of box) such that the bottom of the bronze gear teeth are im-
mersed in the lubricating grease. A common automotive bearing lithium or moly type grease lubricant
should be used. The bronze pinion gear and worm shaft will need to break-in as the unit is first used
causing some heat to build up on the gear shaft and lubricant box during this initial break-in period.
The grease level in the box should be checked and refilled if necessary after approximately 2 to 3
hours of initial use, be sure the worm and bronze gear teeth mesh together. A premium grade wheel
bearing grease for high temperature use is recommended.

Diamond Blade Change-Out
Hold blade in one hand and use a wrench to turn shaft nut counterclockwise and remove nut and
flange from shaft. After reinstalling blade, replace flange and nut and retighten. Do not over tighten
shaft nut.
Lubrication Points
Use premium grade wheel bearing grease when lubricating the saw. Clean the zerk fitting when fin-
ished lubricating. Apply grease slowly; stop when grease is seen between joints. Rotate blade and
driveshaft slowly by hand to spread grease uniformly into ball bearings.
V-Belt Inspection, Adjustment and Replacement
Look for frayed or split belts. Tighten belts for 1/2" to 3/4" of deflection from center of belt. Do not over
tighten.
