1. Holding the drain hose vertically, remove the drain hose cap. (Figure 16)
2. Place drain hose in a five-gallon bucket or collection container.
3. Let the lubricant flow into the bucket for proper disposal.
4. The sludge residue will likely not flow through the hose and will remain inside the reservoir. The
sludge should be removed by removing plug and push out sludge through hole.
5. Wipe the inside of the reservoir with a disposal towel. Replace drain hose cap.
6. Refill reservoir with lubricant to cover the ¼” (6.35) of the blade (see Figure 5).
7. Dispose the used coolant and sludge properly. Conform to Federal, State and Local laws, codes
and ordinances relative to environmental protection.
8. Be sure to check the level of lubricant inside the reservoir after every 3 to 5 hours of use. The
lubricant will be absorbed onto the material, combine with rock mud (sludge) and be lost to heat
and evaporation.
9. Spray WD40 lubricant on arbor shaft threads and jam nut to help prevent rust formation.

MAINTENANCE
Figure 16: Drain Hose Cap
The 7-inch Trim Saw will continue to perform at optimum levels with proper care, daily cleaning and
general maintenance.
CAUTION Place the ON / OFF switch in the OFF position and unplug cord before servicing
and when changing accessories, such as blades.
Maintenance
The Rock Vise has cross feed threads attached to a knob to laterally adjust the vise so that chip thick-
ness is accurately controlled before each chip cut. These threads should be lubricated periodically
with wheel bearing or lithium grease to allow for ease of rotation of the cross feed crank.
Should the wooden jaws on the vise become worn or start delaminating, replacement jaws can be
made from plywood.
