14Engine / Blade Shaft / Gearbox Speed Adjustment

(See Figures 1-6)

WARNING: Serious injury can occur to the operator or people in the work area if the rotational speed (n/min) of the DIAMOND BLADE (2E) exceeds the maximum speed (n/ min) marked on the DIAMOND BLADE (2E).

ENGINE SPEED:

The engine speed on this machine does not need to be changed from the factory set speed. The maximum engine RPM should be 3250, no load.

BLADE SHAFT SPEED:

The blade shaft speed on this machine should be checked before fitting the DIAMOND BLADE (2E) to the machine. Never install a DIAMOND BLADE (2E) if the blade shaft rotational speed (n/min) of the machine is greater than the maximum speed (n/min) marked on the DIAMOND BLADE (2E)! The BLADE SHAFT PULLEY (3-1N, 3-2N) and BLADE SHAFT FLANGE (2B & 2F) may need to be changed if the diameter of the Diamond Blade is changed!

SINGLE SPEED GEARBOX MODEL:

Each saw model, as delivered from the factory, is designed to operate with a specified range of blade sizes inside the blade guard installed on the machine. If a blade size outside the specified range of sizes for your model must be used, then the saw drive configuration must be changed.

If changing from a small to a very large DIAMOND BLADE (2E) on a machine with a single speed gearbox, the Blade Shaft Pulleys (3-1L), Gearbox Pulleys (3-1N), the BLADE SHAFT FLANGES (2B & 2F), and the Blade Guard must be changed.

For example, to change a single speed gearbox model from a 14” (350mm) drive to a 36” (900mm) drive:

1.Change Engine Gearbox Pulley from 6.00” (152mm) diameter to 3.50” (88.9mm) diameter.

2.Change Blade Shaft Pulley from 4.12” (114.3mm) diameter to 5.60” (142.2mm) diameter.

3.Change Blade Flanges from 4.50” (114.3mm) diameter to 6” (152mm) diameter.

4.Change BLADE GUARD (2H) from 14” (350mm) to 36” (900mm).

5.Engine Speed does not change.

See Blade Size Conversion charts for specific information.

THREE SPEED GEARBOX MODEL (14-26, 18-30,

20-36):

CAUTION: Never shift the Gearbox (3-2A) with engine running! Only shift the Gearbox (3-2A) with engine OFF! Gearbox damage could occur.

See “GEARBOX SHIFT LEVER (3-2O)” for details about operating shift lever.

A machine factory equipped with a Three Speed ENGINE GEARBOX (3-2A), while designed to minimize adjustments required for blade size changes, will require some adjustments. The machine is designed to operate with a specified range of blade sizes inside the factory installed blade guard. Color coded information on machine, and information in operation manual, shows allowable blade sizes for current machine drive configuration. There are three (3) machine drive configurations: a) 14-26 for 14” to 26” (350 to 650 mm) blades, b) 18-30, for 18” to 30” (450 to 750 mm) blades, c) 20-36, for 20” to 36” (500 to 900

mm)blades. For example, to change the blade size on a machine drive configuration 18-30 within these range,

18” to 30” (450 to 750 mm), requires only that GEARBOX SHIFT LEVER (3-2O) be moved into the correct position (1, 2, or 3). If the required blade size is outside of the machine drive configuration range [below 18” (450mm) or above 30” (750 mm) for this example], then the machine drive configuration must be changed. This may require shifting the GEARBOX SHIFT LEVER (3-2O), changing

BLADE SHAFT PULLEYS (3-2L), GEARBOX PULLEYS (3-2N) and BLADE SHAFT FLANGES (2B & 2F).

Example: To change a three-speed gearbox model from a 20” (500mm) drive to a 36” (900mm) drive, first determine the machine drive configuration (14-26, 18-30, or 20-36). This should correspond to the BLADE SHAFT FLANGE (2B & 2F) diameter installed on the saw.

If the machine drive configuration is a 20-36, the FLANGE

(2B & 2F) diameter is should be 6.00” (152mm):

a)Verify proper pulley diameters are installed (See Blade

Size Conversion charts for specific information).

b)Shift the GEARBOX SHIFT LEVER (3-2O) from 3 to 1.

c)Verify that machine drive configuration and blade shaft speed corresponds with information in operation manual, and gearbox range decal (542 19 06-00).

If the machine drive configuration is an 18-30, the FLANGE (2B & 2F) diameter should be 5.00” (127mm):

a)Change the BLADE SHAFT PULLEY from 4.50” (114.3

mm)diameter to 5.20” (132mm).

b)Change the BLADE SHAFT FLANGE from 5.00” (127mm) diameter to 6.00” (152mm).

c)Shift the GEARBOX SHIFT LEVER (3-2O) from 2 to 1.

d)Verify that machine drive configuration and blade shaft speed corresponds with 20-36 drive configuration information in operation manual.

e)Install the 20-36 drive configuration decals (Decals

542 19 06-00, 542 20 65-46, 542 20 65-49 are required). See the “Decals and Locations” page of this manual for more information.

If the machine drive configuration is a 14-26, the FLANGE

(2B & 2F) diameter should be 4.50” (114.3mm):

a)Change the BLADE SHAFT PULLEY from 4.12” (105mm) diameter to 5.20” (132mm).

b)Change the BLADE SHAFT FLANGE from 4.50” (114.3mm) diameter to 6.00” (152mm).
