First Time Assembly:

Tools Required:

•Screwdriver (for Arbor Lock)(Not Included).

•2” (50.8mm) Socket, and Socket Wrench (Not Included).

•Combination Spanner (supplied with machine).

•Torque Wrench.

Unwrap SpeedMill bowl / Hub Assembly from the packaging. Initially all three sizes of Speed- Mill Bowls (4”, 6”, 8”) are as- sembled to the Hub Assembly.

Change the mounted bowl sizes if desired. Turn the 2” (50.8mm) hub nut Counter- Clockwise to remove.

Lift off the smaller bowls, and configure the bowl / hub as- sembly as desired. Example: 6” and 8” bowl combination is popular. ALWAYS mount the 8” bowl, it may shield operator in case of blade breakage.

CAUTION!

Always install the 8” SpeedMill Bowl (P/N 542 19 61- 89) before using the machine! The 8” SpeedMill must always be installed even if the machine will only be used to cut and bevel smaller diameter pipes. Besides serving as a beveller for 8” pipes the 8” flange is also designed to cover the area between the guard and the flange and to prevent unintentional contact with the blade.

Install and Re-tighten the 2” (50.8mm) hub nut. Torque to 130-215 in-lbs. (15-25 Nm). NOTE: Do not tighten exces- sively – nut will tighten during cutting process – making dis- assembly difficult.

Loosen and remove the blade shaft screw & washer from the power cutter. Use the combi- nation spanner supplied, and a Screwdriver to lock the blade shaft in position, if required.

Use a Screwdriver to lock the blade shaft in position. Push the screwdriver into the slot (see picture) and rotate the ar- bor until the screwdriver stops the rotation.

Verify that 1” (25.4mm) adapter (P/N 506 37 96-25) is pushed onto blade shaft so it contacts the inner flange. The mount- ing surfaces of the flange and bushing arbor must be undam- aged, clean, and free of debris. Verify that the flange (P/N 506 02 87-01) has a diameter of 4.13” (105mm).

Mount a 12” (305mm) diam- eter, 1” (25.4mm) arbor High Speed Reinforced Abrasive Blade (not included) on the blade shaft.
