correct. Check the oil level frequently to ensure that the level never falls below that specified in the engine operation manual. If the oil level is low, add SAE 10W30, service classification SF or SG oil (for normal conditions) as recommended in the engine operation manual. DO NOT overfill engine with oil!

4. Operating Instructions

Preparing to Saw

1.Perform daily maintenance to saw (see chart).

2.Fuel saw if required. Use good grade of regular gasoline (14).

3.Remove blade guard and mount blade securely on blade shaft. For saws equipped with Magnalock one-piece outer collar blade shaft, insert the outer collar through the blade and into the female inner collar. Make sure the blade collars are clean and free of nicks and burrs on the clamping face. Make sure inner collar is tight on the shaft and drive key is in place. Check the drive pin in the outer collar for damage, loose fit or being bent. Check the blade arbor for gouges, nicks or burrs. SAW BLADE MUST BE HELD TIGHT AND RUN TRUE to achieve the proper blade performance.

4.If using wet cutting diamond blades, visually inspect coolant spray tubes for plugged or damaged openings.

Clean and repair as necessary. Proper coolant flow is essential to good blade performance.

5.Visually inspect blade guard for cracks, hinge failure or loose mounting. Repair or replace guard if necessary. DO NOT USE SAW WITHOUT BLADE GUARD SECURELY IN PLACE!

6.Set line guides.

To Saw

1.Place water safety switch in the OFF position.

2.Start engine and allow it to warm up at half throttle. Observe proper oil pressure and charging amps.

3.Set “Quick Stick” speed control handle (2) to neutral and engage transmission engagement lever (10).

4.Open throttle (5) to full speed position. Engine governor is factory

set. DO NOT CHANGE SETTING unless you have changed the saw blade capacity to accommodate larger or smaller diameter blades.

5.Turn on water to blade (8). Set water safety switch to ON position (leave off if dry cutting). If engine stops, recheck water supply. The water safety switch will automatically shut off the engine if proper water pressure is not supplied.

6.Position saw over cut.

7.Lower blade using toggle switch located in speed control handle (2) (follow instructions on handle). Releasing switch will stop blade from lowering. Stop lowering when blade contacts pavement. With blade touching pavement, set cutting depth indicator (6) to “0”, then continue lowering until the desired cutting depth is shown on the cutting depth indicator.

8.To use depth stop control (3) turn handle clockwise until resistance is met. For greater depth, turn handle counter-clockwise, for lesser depth turn the handle clockwise.

9.Move speed control handle (2) forward SLOWLY until proper cutting speed is achieved.

When Cut is Finished

1.Put speed control handle (2) back to neutral position.

2.Raise blade from cut by using the toggle switch in speed control handle. When switch is released, the raise will stop and hold in place.

3.Once the blade is completely out of the cut, turn off water to blade (8).

4.Close throttle (8) to idle position. Let engine cool down before stopping.

DO NOT STOP ENGINE AT FULL THROTTLE!

NOTE: All sawing is done with engine at full throttle. Engine governor is factory set to achieve proper blade speeds and engine performance.

DO NOT CHANGE GOVERNOR SETTING unless you are changing blade capacity (Diameter).

Straight Line Sawing Adjustment

Your saw is equipped with rear axle adjustment to adjust for blade lead off. The adjustment nut is located at the back of the saw on the lower left frame. To adjust saw, stop saw, stop forward drive, remove blade from cut and stop engine. Loosen rear axle mount bolts on left rear of saw.
