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 cover by removing the four mount-
ing screws that attach the cover to the gear box. Check the level of the grease lubricant in the box by ensuring
that gear box is filled 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 immersed in the lubricating grease. A common automotive bear-
ing lithium or moly type grease lubricant should be used. The bronze pinion gear and worm shaft will need to
broken-in as the unit is first used, causing some heat to build up on the gear shaft and lubricant box during this
initial broken period. The grease level in the box should be checked and refilled if necessary after approximate-
ly 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 finished
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.
