Adjustments can be made while sawing or not sawing.

Visually confirm the axle movement and direction.

Standard Model Saw with Manual Axle Adjustment

The axle (4E) is adjusted by turning the M12 MANUAL AXLE ADJUSTMENT BOLT (1CC) located at the rear lower left of saw frame.

If the saw steers to the RIGHT while sawing, turn the MANUAL AXLE ADJUSTMENT BOLT (1CC)

COUNTERCLOCKWISE.

If the saw steers to the LEFT while sawing, turn the MANUAL AXLE ADJUSTMENT BOLT (1CC) CLOCKWISE.

Rear Pivot Model (Saw with Differential Pivot option):

Simply bear against the HANDLEBARS (6G) to hold the saw on the cutting line. DO NOT shift the DIFFERENTIAL SWITCH (1J) from the Center “Lock” position. The Left, “Pivot”, position of the DIFFERENTIAL SWITCH (1J) is NOT for adjusting the straight line sawing of the saw.

10 Maintenance

(See Figures 1-6)

Before performing any maintenance,ALWAYS park the machine on a level surface with the Engine OFF and the ENGINE START SWITCH (1H) in the “0” (OFF) position.

After each use CLEAN the machine.

LUBRICATION:

ENGINE OIL: Check daily (5B). Change Engine Oil and ENGINE OIL FILTER (5D) after every 100 HOURS of operation. See engine manual for recommended oil. SAE 15W40 API Class CF, CF-4, CG-4, or CI-4 engine oil is generally recommended. Capacity is 7.8 quarts (7.4 liters) with ENGINE OIL FILTER (5D). Align oil level with upper mark on ENGINE OIL DIPSTICK (5B). Use ENGINE OIL DRAIN VALVE (3-1I, 3-2I) to drain engine oil:

Remove DIAMOND BLADE (2E), and then lower saw to a horizontal position.

Raise and secure ENGINE HOOD (6E).

Put a container, large enough to contain the engine oil capacity, near the end of the oil drain hose. Open ENGINE OIL DRAIN VALVE (3-1I, 3-2I) and allow contents to drain into the container. Dispose of the used engine oil in an environmentally safe manner. Securely close ENGINE OIL DRAIN VALVE (3-1I, 3-2I). Fill with recommended oil until oil level aligns with the upper mark on ENGINE OIL DIPSTICK (5B).

LUBRICATE EVERY 100 HOURS:

• Front Axle Pivot Bearings (4C)

LUBRICATE EVERY 250 HOURS:

• Bladeshaft Seals and Bearings (4A) 2 Pumps only

HYDRAULIC SYSTEM:

Refer to Section 12 -“Hydraulic System”

ENGINE GEARBOX (3-1A, 3-2A):

Change oil after every 500 hours of operation. Use SAE 75W90 synthetic gear lubricant.

DO NOT OVERFILL! Fill only to “Check Port” or excess

will overflow.

Single Speed ENGINE GEARBOX (3-1A): Oil Capacity is 32 oz. (USA) (0.946 Liter)

Three Speed ENGINE GEARBOX (3-2A): Oil Capacity is 60 oz. (USA) (1.77 Liter)

Drain cooling water from Water Drain Valve (3-1C, 3-2C) to prevent rust and freeze damage (Every Day).

The engine cooling fluid is 50/50 anti freeze/water mixture. See engine manual for recommendations.

Clean the RADIATOR AIR FILTER ELEMENT (1DD) every 50 hours or when required, replace if damaged. Always keep RADIATOR AIR FILTER ELEMENT (1DD) in place.

Check hoses and hose clamps for damage and looseness. Tighten or replace as required.

Check Coolant Freeze Protection yearly.

Flush and Clean radiator and cooling system every 500 hours.

Maintain at least 1/4 full coolant level in RADIATOR COOLANT OVERFLOW BOTTLE (1Y) when engine is cool.

AIR FILTER:

Clean the Air Filter Outer Element (5A) when the AIR RESTRICTION INDICATOR (1N) Red Signal appears. DO NOT clean the Inner Safety Element (5A)!

To change or clean the air filter element:

Remove the Air Filter Housing (5A) by opening the two (2) Air Filter Housing Clamps, and pulling the housing off.

Pull the Air Filter Outer Element out of the filter housing and replace, or clean by using low pressure compressed air [2.75 bars (40 psi) - MAXIMUM)] from the inside out. DO NOT clean the filter element by tapping it on the ground or other objects, this will damage the filter element!

Install the new or cleaned Air Filter Outer Element by pushing it into the housing.
