FS2/FS2SP CONCRETE SAW — MAINTENANCE

CAUTION:

General maintenance practices are crucial to the performance and longevity of your saw.The extreme environments of sawing operations require routine cleaning, lubrication, belt tensioning, and inspection for wear and dam- age

WARNING

The following procedures devoted to mainte- nance can prevent serious saw damage or malfunctioning. Before servicing or inspection, ALWAYS park the saw on a level surface with

the blade removed, and the Console Engine ON/OFF switch & Engine ON/OFF switch in “OFF” position.

WARNING

Some maintenance operations may require the engine to be run. Ensure that the mainte-

nance area is well ventilated. Exhaust contains poisonous car- bon monoxide gas that can cause of unconsciousness and may result in DEATH.

General Engine Care

1.ENGINE CHECK: Check daily for any oil and/or fuel leakage, thread nut & bolt tightness, and overall cleanliness.

2.ENGINE OIL: Check daily. Inspect with blade removed and saw frame level on a level surface. Keep the oil clean, and at the proper servicing level (Figure 8).DO NOT OVERFILL! SAE 10W-30 of SG is recommended for general use.

3.ENGINE OIL CHANGE: Change engine oil the first month or 20 hours of operation.Then every 3 months/or 50 HOURS

NOTE

ALWAYS dispose of used oil in a responsible manner.Ensure that the disposition of all hazardous waste is handled properly. Call your Recycling Center for information about recycling engine oil.

5.ENGINE TANK & STRAINER: Clean every year/or 300 hours.

6.FUEL LINE: Replace every two years/or as necessary.

7.SPARK PLUG: Clean/adjust every 6 months/or 100 hours. Replace every year/ or 300 hours.

Bearing Lubrication Care

There are seven (7) grease points for the FS2 Push Model saw, and nine (9) grease points for the FS2SP Self-Propelled Model saw. [Use only Premium Lithium 12 based Grease, conforming to NLG1 Grade #2 consistency.]

1.Front Wheels (2): Grease daily, see page 42, item 8, Undercarriage Assembly.

2.RearWheels(2): Grease daily, see page 44, item 10, Rear Axile Assembly.

3.Blade Shaft Bearings (2): Grease daily, see page 46, item1, Blade Shaft Assembly.

4.Raise/Lower AdjustTube (1): Grease daily, see page 60, item 26, Raise/Lower Assembly.

5.Transmission Shaft Bearings (2): Grease weekly/or 25 hours,seepage70,item28,TransmissionAssembly(forself- propelled models only).

NOTE

When cutting DRY, lubricate blade shaft bearings 2 to 3 times daily. The grease can provide an added protective seal for the bearings.
