GENERAL ELECTRICAL TROUBLE SHOOTING Circuit Breaker During Start Up or Not Cutting: Verify that the power supply voltage matches the motor name plate voltage Failure to run the motor on the proper voltage will damage the motor and is not covered under warranty.
BBM307 Motor Troubleshooting Verify voltage to the motor 115v/60 Hz/1 Phase Verify extension cord See: Extension Cords page 15 What is the motor doing when switch is turned on (nothing, humming, tries to turn on but shuts off, tripping of circuit breaker) It could be a dirty air filter, a faulty start, or a tripped/damage power supply circuit breaker.

Verify that the voltage change switch on the motor matches the power supply voltage see Voltage Change Switch page 17.
OPERATION Installing the Blade The Blade installation for the BBM307 and BBM158 are the same. Please note that the Blade Shaft Bolt is a left-handed thread. 1. Verify that the power switch is in the OFF position 2. Disconnect the machine from any power supply 3.
OPERATION Blade Shaft Directional Airs and Blade Guard Rotational Direction 6. Mount the outside collar on the spindle so that the diamond blade is securely positioned between both collars. Then, with the washer positioned on the screw, insert the blade shaft screw into the end of the blade shaft and turn counterclockwise to secure the blade between the two collars.

OPERATION 2. Move the conveyor cart near the blade and pull down on the head until the blade is lowered to a point where it will lightly contact the top of the material. Then start "step cutting" - which means passing the material beneath the blade with rapid, (50 to 60 strokes per minute) full length strokes, taking a shallow cut (approximately 1/8"...
OPERATION Jam Cutting In "Jam" cutting the head is locked in a fixed position and the material is pushed into it as shown in the sketch at the bottom. "Jam" cutting with the head locked in a fixed position usually provides greater efficiency.
OPERATION Dry Cutting If dry cutting is required follow all local, state and OHSA regulations on Silica Dust Control. Use proper PPE within accordance to OSHA regulations. Cutting dry exposes the operator to Silica Dust see DUST AND SILICA WARNING on page 5 for details. The BBM307 and BBM158 can be installed with the Optional Vacuum Attachment conveyor cart (cutting table) which allows the BBM307 or BBM158 to be used with any OSHA approved HEPA vacuum.
