Page 4: Safety Rules
Make certain the work area is well lighted and that a proper exhaust system is used to minimize dust. Powermatic recommends the use of anti-skid floor strips on the floor area where the operator normally stands and that each machine’s work area be marked off. Provide adequate work space around the machine. - Page 5 Misuse. Do not use this Powermatic cut-off saw for other than its intended use. If used for other purposes, Powermatic disclaims any real or implied warranty and holds itself harmless for any injury or damage which may result from that use.

Page 9: Receiving
The saw cabinet should be bolted to the floor through the holes at the four corners, using high quality lag screws. Unpainted surfaces, such as the table and fence, have been given a protective coating at the factory. -
Page 10: Electrical Connections
A power plug is not provided with the COS18. You may either connect one, or "hard-wire" the machine directly to your electrical panel provided there is a disconnect near the machine. -
Page 11: Dust Collection
DUST COLLECTION Powermatic recommends the use of a dust collection system with this cut-off saw. The collector should have sufficient capacity (600 CFM) for this size machine. Mount the dust collector via a 4" hose to the outlet on the blade access door. -
Page 12: Air Supply
AIR SUPPLY The correct air pressure for the COS18 saw is 70 PSI. Attach the hose from your air source to the machine's air valve as shown in Figure 9. SQUARING THE FENCE The best way to square the fence is to make sample cuts. - Page 13 To mount roller tables to saw: Mount an angle bracket to the pre-drilled holes in the side of the saw cabinet with four M8 x 20 hex cap screws and four M8 flat washers (Fig. 10). Do not fully tighten yet.

LEVELING & ALIGNING ROLLER TABLES Each roller table must now be leveled with the main saw table and aligned with the fence. (The fence must be square with blade – see "Squaring the Fence", page 11.) WARNING: Disconnect saw from both air and electric power sources. -
Page 15: Adjustments
BLADE TRAVEL To adjust the speed by which the saw blade (and the clamp) travel up and down, open the cabinet door and locate the upper and lower pressure regulating valves which are attached to the air cylinder (Fig. -
Page 16: Belt Replacement
BELT REPLACEMENT Release tension on the v-belt and remove old belt. Make sure the new belt is properly situated into the v-grooves of the pulley. Tension new belt. OPERATION WARNING: Do not place your hands close to the guard/clamp at any time during operations. -
