NOTICE

Parking Brake must be dis-engaged to start engine (FS 520 & FS 524). Move Transmission Engagement Lever

(PP)rearward to Dis-Engaged position.

Gasoline Engine Models:

Refer to the engine operating manual for proper engine operation.

FUEL: Unleaded gasoline is recommended. See engine operation manual for more information.

OIL: Check that engine oil level is correct using the Engine Oil Dipstick (Z). See Maintenance section of this document or engine operation manual for more informa- tion.

Because the engine often operates at an angle, check oil level with engine horizontal. Check frequently to ensure that oil level never falls below lower mark on dipstick. 10W30 oil is recommended. See engine operation manual for more information.

NOTICE

If engine is equipped with a low oil shutdown system, engine will not start if oil level is low. Also, engine may stop if maximum angle of operation is exceeded. See engine operation manual.

All Models:

Front Pointer (A) must be checked for alignment with blade. Lay a straight edge along Inner Flange (I). Align Front Pointer (A) to straight edge. If required, adjust Front Pointer (A) by loosening nuts that hold Guide Wheel (B) in place. Align Guide Wheel (B) to straight edge and re- tighten nuts.

Check that water tubing in the Blade Guard (C) is open and that each side of blade has an adequate supply of water.

Test the water supply for pressure and quantity (flow) before starting the saw.

Saw only as deep as the job specifications require. Saw- ing deeper than required will add excessive wear the blade and machine.

Cut in increments of 50mm (2 inches) deep until cutting depth specification is reached. This is known as “step cutting”.

Saw only in a straight line. Mark cutting line clearly so saw operator can follow line without difficulty. Saw should NOT be twisted from side to side to force blade back on line.
