FS3SP CONCRETE SAW — MAINTENANCE

General Transmission Care

All FS3SP Models utilize spline gear wheel design coupled with an EATON Model 7 Hydrostatic Transmission that provides forward/reverse propulsion. The simple design of the system keeps maintenance to a minimum.

1.Transmission Reservoir Cup: Check every 8 hours

of operation. When the transmission is cold (A), check oil level against the level indicator (see Figure 25).

DO NOT use multiple viscosity oils! DO NOT OVERFILL.

Figure 25. Transmission Reservoir

2.Servicing: The transmission reservoir is factory filled. Should servicing be required, use SAE20W-20, API classi- fication (SE,CC,CD) or better, General Motors Dexron B, FordM2C-33F,M2C-41AorInternationalHarvesterHy-Tran fluids. For extreme hot weather, drain oil and refill with an oil having a viscosity of SAE30W-30 or SAE40W-40.

3.Drive Chain: Check every 50 hours. Periodically wipe the chain clean and relubricate with penetrating chain oil.

The drive chain may stretch requiring tension adjustments. Loosen the (3) transmission attachment screws (see page 68, item 11), and pivot the transmission in the“U”slots of thetransmission mount untilthepropertensionisachieved. (see page 68, item 12). EXCESSIVE TENSION ON THE

DRIVE CHAINWILL REDUCE CHAIN LIFE.

AdjustV-Belt Alignment/Replacement Pulleys

The V-belts and their respective pulleys have been professionally aligned at the factory. If there is a requirement to remove/replace or adjust the pulleys, proceed with the following instructions.

1.Select the proper sized pulley both in outside diameter and arbor size. Use approved Multiquip parts to ensure the component compatibility.

2.A change in Pulley diameters may require specifically sized V-Belts. Contact Multiquip Servive Department to en- sureV-Beltcompatibility.

3.Remove theV-Belts from around the Pulley(s).

4.Removethesetscrewsthatsecurethepulleystotherespec- tive shafts (PTO shaft) for engine pulley or the (bade shaft) for the blade shaft pulley.

5.Remove/replace the pulley by sliding it off the shaft.

6.Reorient the new pulley on the shaft, and ensure precise pulley alignment by utilizing an accurate straight edge (see Figures 26 and 27).

7.Replace/tighten set screws treated with a drop of LOCTITE

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

9.Reference the final stages of the DriveV-Belt(s) Replace- ment steps.
