SpeedCut 21
General Information
The cutting frame, of the SpeedCut is raised and lowered by the hydraulic unit in the base. Working in
conjunction with this assembly are the electrical units composed of the control cabinet, front mounted
controls, limit switches, blade micro switch, pump motor, and blade drive motor.
Hydraulic System
• Pump – Positive displacement, rotary type. Forces oil into lifting cylinders.
• Use Mobil DTE 25 Hydraulic Oil or equivalent for hydraulic pump.
• Pump Details
• SpeedCut 78/98 Hydraulic Pump (for Saw Head Motion) - Capacity of 10 gallons of Mobil
DTE 25 Hydraulic Oil or equivalent, 1 Horsepower.
• Cylinder & Piston – steel cylinder and piston with neoprene cup.
• Solenoid Valve – Regulates flow of oil through line as blade pressure increases and
decreases, actuated by blade micro-switch.
• Needle Valve – Governs discharge of oil from cylinder as frame lowers.
Electrical Systems
• Control Cabinet – Contains transformer to provide 110 volts to all controls, magnetic
starters with adjustable overloads, relay and terminal blocks.
• Limit Switches – Upper limit switch stops upward travel of frame at predetermined
height set by trip collar. Lower limit switch stops blade motor at end of cut.
• Blade Micro-Switch – An automatic device is actuated by pressure on the blade
and controls the solenoid valve to maintain constant downward blade force. It also
activates an indicator light on top of the front mounted controls.
• Pump Motor –Drives hydraulic pump.
• Blade Drive Motor – “V” belt drive to gear case.
• Front Mounted Controls – Push buttons for blade motor, feed, emergency stop.
