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
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
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.
