Page 56

• Install Air Filter Outer Element by pushing it into the housing.

• Install the Air Filter Housing (5A) and close the three

(3) Air Filter Housing Clamps (5A).

The three (3) Air Filter Housing Clamps (5A) can NOT be closed unless the Air Filter Outer Element is properly installed.

• Replace the Inner Safety Element once per year or if it becomes damaged.

•Replace any damaged filters or gaskets.

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

Wheels and Hubs:

• Check for excess wear and looseness. Tighten or replace as required.

FUEL FILTER :

• Replace Spin-On Fuel Filter (5F) every 500 hours.

11 Blade Shaft V-Belt Tension

(See Figures 1-3)

This saw is equipped with high tension banded V-belts. The belts are properly tensioned at the factory but after a few hours of operation they will stretch and become loose. Re-tension belts as described below.

To Tension V-Belts:

• Turn ENGINE START SWITCH (1H) to the “0” (OFF) position.

• Open ENGINE HOOD (6E): See Figure(s) 3-1/3-2, Item 3-1D/3-2D for procedure.

• Using the BLADE SHAFT WRENCH (2J), loosen the horizontal clamping bolts (3K) at the front of the machine.

• Turn each of the two (2) vertical BELT TENSIONING BOLTS (3-1J, 3-2J) [at the front of machine, below the ENGINE GEARBOX (3-1A, 3-2A)] CLOCKWISE until the V-BELTS (3-1M, 3-2M) are tight.

• Replace V-BELTS (3-1M, 3-2M) in complete sets only.

• For optimum V-Belt tension use Goodyear TensionRite™ Strips, P/N 542 19 13-68. TensionRite™ strips are sup- plied with belts purchased from your dealer.

• Never tension V-BELTS (3-1M, 3-2M) beyond the original factory tension. Loose V-Belts result in poor saw performance and short belt life.

Replace all shields and guards. Never run Saw with out all shields and guards in place.

12 Hydraulic System

(See Figures 1-6)

The hydraulic system on this saw is used to RAISE/ LOWER the Diamond Blade (2E), and to propel the saw FORWARD and REVERSE. The hydraulic system consists of a Hydrostatic Pump (5N), (2) Hydraulic Wheel Motors (4F), Hydraulic Filter (5K), DC Lift Pump (5H), Hydraulic Oil Reservoir (5J), Flow Control Valve (1U), and Hydraulic Lift Cylinder (4G).

•Hydraulic Filter (5K) should be changed after the first 50 hours of operation, then every 250 hours of operation.

•Check Hydraulic Reservoir (5J) fluid level periodically.

Maintain oil level with SAE 15W40 API Class SE, CC, CD motor oil. DO NOT OVERFILL, check oil level when saw is level.

•Change hydraulic fluid every 500 hours of operation.

Fill Hydraulic Reservoir (5I,5J) with approximately 2.5 quarts of SAE 15W40 API Class SE, CC, CD motor oil. DO NOT OVERFILL! Check oil level when saw is level.

•The lowering rate of the saw can be adjusted using the Flow Control Valve (1U) at the rear of the saw. If the saw falls too quickly, turn the knob on the Flow Control Valve (1U) CLOCKWISE until an adequate lowering rate is set.

13 Important Advice

(See Figures 2-3)

•Tighten loose nuts and bolts regularly, particularly after several hours of operation.

•Check V-Belt (3-1M, 3-2M) tension regularly. Re-tighten V‑Belts (3-1M, 3-2M) as necessary.

•Remove the Diamond Blade (2E) for storage. Store it carefully.

•Check the water spray over the Diamond Blade (2E) periodically.

•Tighten the Diamond Blade (2E) firmly on the Blade

Arbor (2C).

•Make sure the contact faces of Flanges (2B & 2F), Diamond Blade (2E), and Blade Shaft (2I) are clean.

Store in a safe place out of reach of children. Remove all adjustment tools and wrenches. Store diamond tool in a safe place so it cannot be damaged.
