The BBM307/YBM307 Block Buster Mini Masonry saw is designed with three different cutting
heights for jam cutting, a moving head for chop (or plunge cutting), and a moving cart combined
with the moving head for step cutting to help make any cutting task easier.
Before adjusting the cutting height always disconnect the electrical power supply.
To adjust the BBM’s fixed cutting position, pull up on the Angle Lock Pin (see Figure 1-1:
Angle Lock Pin), move the head to the new position, release the Angle Lock Pin, and rotate the
cutting head up/down until the Angle Lock Pin locks into position (lowest position for cutting thru
bricks, the middle position for cutting medium size material, and the upper position is for cutting
block.) (See figure 1-2: Angle Locking Position).
To operate the BBM Block Buster Mini as a chop or plunge saw: pull up on the Angle Lock Pin,
rotate 90 degrees, and release. Now the cutting head can be rotated by pulling up or pushing
down on the cutting head handle. When not in use, always lock the head into one of the
three cutting height positions.
Do not install the blade until it is time to use the saw!
This machine is designed for the use with steel center diamond blades ONLY!
Lock the cutting head in place before transporting the BBM
ANSI regulations prohibit the transportation of any concrete saw with the blade installed!
Do not lift the saw by the cutting head. This may result in injury or damage to the machine.
Disconnect the power supply and lockout the power switch before when moving, maintaining, or
servicing the machine.
