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) by turning each of the two

(2) HOOD LATCHES (3-1D, 3-2D) counter clockwise for 180 degrees. For European CE models, a tool, such as a screw driver must be used to open these latches. Rotate the ENGINE HOOD (6E) upward, and secure it in the open position using the HOOD SUPPORT (6H).

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 supplied 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 TRANSMISSION PUMP (6K), (2) HYDRAULIC WHEEL MOTORS (4F), HYDRAULIC FILTER (5K), DC LIFT PUMP (5H), HYDRAULIC OIL RESERVOIR (5J), SAW LOWER- ING SPEED CONTROL KNOB (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. Fill a new HYDRAULIC FILTER (5K) with SAE 10W30 motor oil before installation.

Check HYDRAULIC OIL RESERVOIR (5J) fluid level periodically. Maintain oil level with SAE 10W30 motor oil. DO NOT OVERFILL, check oil level when saw is level.Fill oil to bottom of HYDRAULIC RESERVOIR FILL (5I) port.

Change hydraulic fluid every 500 hours of operation.

Fill HYDRAULIC OIL RESERVOIR (5I,5J) with approximately 2.5 quarts of SAE 10W30 motor oil. DO NOT OVERFILL! Check oil level when saw is level. Fill oil to bottom of HYDRAULIC RESERVOIR FILL (5I) port.

The lowering rate of the saw can be adjusted using the SAW LOWERING SPEED CONTROL KNOB (1U) at the rear of the saw. If the saw falls too quickly, turn the knob on the SAW LOWERING SPEED CONTROL KNOB (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-BELTS (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 OUTER

FLANGE 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
