Multiquip FS2 Raise/Lower Height Adjustment, Setting The Height Of The Depth Gauge Pointer

FS2 CONCRETE SAW — MAINTENANCE

Raise/Lower Height Adjustment

The FS2 is equipped with an Raise/ Lower assembly that is supported by the following:

λACME Screw

λPrecision Thread

λDepth Gauge Bearing

λDepth Gauge Pointer

λTube Height Adjustment

The height adjustment of the FS2 has been factory set utilizing precision standards.

Reference Manual Raise and Lower Assembly on page 52 unless otherwise noted.

Setting The Height Of The Depth Gauge Pointer

Perform the following to set the height of the Depth Gauge Pointer:

1.Place the saw on a level working surface.

2.Remove the rear panel cover, see page 46, item 9.

3.Install an appropriate new diamond blade on the saw and take reference to the diameter.

4.Lower the blade until flush contact is made with the level surface.

5.Loosen the two hex nuts, item 18, that tighten against the upper and lower rod ends, item 19.

6.Loosen the hex nut, item 13, that secures the plunge ball, item 12, depth lock against the adjustment tube.

7.Loosen (counter-clockwise) the plunge ball with an allen wrench. This will unlock the plunge ball from the ACME screw, item 9.

8.Set the blade height indicator to "0" (relative to the diameter of the blade and depth scale). See Figure 6, "Concrete Saw Console".

10.Remove the upper pan-head screw, item 20, to enable the rod end adjustments.

11.Adjust the rod ends as required to ensure that the throw of both rod ends and threaded rod, item 14, support the "0" position of the depth gauge located on the console.

12.Tighten the plunge ball, item 12, to the full depth against the ACME screw, item 9.

13.Unscrew the plunge ball, item 12, 1 FULL TURN (counter- clockwise).

14.Tighten the hex nuts, item 13, against the "Adjustment Tube", item 10, to lock the plunge ball in place.

V-Belt Tension Check

Check tension after first day of operations, then weekly/or 25 hours. Replace as required (see Figure 14). NEVER operate

with less than 3 belts.

The FS2 is equipped with (3) premium 3VX V-belts (Figure 14) that provide optimum torque transfer.

The saw must be operated with all (3) V-belts, and must be ad- justed collectively and properly to be effective

The V-Belt adjustment of the FS2 has been factory set utilizing precision standards. For V-Belt adjustments only, see page 23, V-belts Alignment Tensioning.

V-Belt Replacement

To replace the entire set of V-belts (3) perform the following procedure:

Figure 26. V-Belts

1.Reference pages 38 (Blade Shaft Assembly), 40 (Engine Mount Assembly) and 42 ) Pointers and Covers Assembly).

2.Loosen the tension on the V-Belts.

3.Remove the Belt Cover, item 4, page 42.

4.Loosen the Carriage Bolts, item 11, page 40.

5 Loosen the Hex Head Cap Screws, item 12, page 40.

6.Rotate the engine down to provide slack in the V-Belts.

7.Loosen shaft bearing(s), hex head cap (shaft bearing) screws item 11, page 38.

8.Remove the (2) hex head cap screws, item 11, page 38, that support the ‘pulley-side’ blade shaft bearing.

9.Orient the blade shaft so the belt(s) to be replaced can slide off the blade shaft pulley and engine pulley.

10.Orient the replacement belt(s) around the blade shaft pulley and engine pulley.

11Replace and tighten the (2) hex head cap shaft bearing screws, item 11, page 38.

V-Belt Tension

1.Adjust carriage bolts, item 11, page 40, until the proper belt tension is achieved.

2.Tighten the (2) hex head cap screws, item 12, page 40.

3.Replace the belt cover, item 4, page 42.
