FS3SP CONCRETE SAW — MAINTENANCE

DriveV-Belt Check

Operating the saw with less than four (4) V-belts, or belts that are slipping or are OverTensioned will significantly diminish the performance of the saw, and may cause damage to the blade.

1.The V-Belts of the FS3SP have been factory set utilizing precisionstandards.

DriveV-Belt(s) Replacement

Reference Pointers and Covers Assembly (page 50), Blade Shaft Assembly (page 46), Engine Mount Assembly (page 48) for this operation.

1.Remove the Belt Guard (page 50, item 17), then loosen the tension of theV-Belts

2.Loosen the Engine Mount Carriage Bolt (page 48, item 4).

3.Loosen the (4) 3/8” HHC screws (page 48, item 7).

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

5.Loosenthe(2)3/4”HHCscrewsthatsupporttheBladeShaft Bearingsontheright-sideofthesaw(page46,item11,also see Figure 30).

6.Removethe(2)3/4”HHCscrewsthatsecuretheBladeShaft BearingontheV-Belt side ofthesaw(page46,item11 also see Figure 30).

Adjust V-BeltTension

1.Tightendowntheenginemountcarriagebolt(page48,item 4,) and monitor the tension on the belts.

2.Determine the proper tension (Figure 31) by using a tensionmeter against the inside belts at mid point between the two pulleys (6-9 lbs.), or by deflecting the center belts at mid point 3/8” (10 mm) to 1/2” (13 mm).

CORRECT V-BELT

TENSION 3/8 IN. (10 MM) TO 1/2 IN.(13 MM) WHEN DEPRESSED AT MIDPOINT AS SHOWN

3.Once the proper tension has been applied to the belts, tighten the (4) 3/8” HHC screws (page 48, item 7).

4.Replace and secure the Belt Guard (page 50, item 17).

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

8.Select the proper Multiquip replacementV-Belts (see page 46, item 12).

9.Remove the wornV-Belt(s).

10.Orient the proper replacement V-Belt(s) around the blade shaft pulley and engine pulley.

11.Replace and tighten the (4) 3/4” HHC screws that secure the Blade Shaft Bearings to the saw frame.

General Cleanliness

Clean the machine daily. Remove all dust and slurry build up. If the saw is steam cleaned, ensure that lubrication is accom- plished AFTER steam cleaning operations.
